Zhejiang Changxing Cement: Quiet Change July 17, 2007 Protected color: default white Altair purple Apple green Desert yellow Rose red Font: small font Large font When we are full of respect to sort out and comment on the structural adjustment of the cement industry in Zhejiang, there is a place that can not be left out: here gathered Zhejiang Three Lions, Zhejiang Mountain Eagle, Zongsheng Cement, Zhejiang Jinlong, and so on a large number of familiar enterprises in China's cement industry, cement, cement, and so on, the cement industry, the cement industry. Familiar enterprises, cement production accounted for more than one-tenth of the total cement production in Zhejiang; here the introduction of the country's first cement kiln dismantling incentives, the first in the province to complete the elimination of outdated cement production goals; here the investment in the construction of Zhejiang's first 1,000 tons / day, 2,500 tons / day, 5,000 tons / day of new dry-process cement production line, the successful launch of the first domestic 2500 tons / day, 5000 tons / day full localization of pure low-temperature waste heat generator sets ......
This is Changxing County, Zhejiang Province. A place located in the north of Zhejiang Province, bordering Suzhou and Anhui Province, with a favorable geographical location, rich mineral resources, the cement industry is uniquely suited to the development of the place. Here, the 143-kilometer-long "Oriental Rhine River" - Changhu Shen Golden Waterway and West Campsis Creek after the confluence, beautifully drawn an arc, dashing east, the Taihu Lake on the west bank of Changxing and Huangpu River Shanghai quietly connected together, so that the landlocked Changxing added a sense of openness and global vision.
Changxing County cement industry restructuring in Zhejiang, and even the country, have sample significance. From 1999 to 2005, Changxing County, the county government from the scientific development, harmonious development, sustainable development of the requirements of the starting point, seriously implement the national industrial policy. 2003, they and the local cement enterprises repeatedly meeting, forward-looking preparation of the "Changxing County Cement Clinker Base Development Plan"; in February 2004, in the cement market in Zhejiang a good situation, Changxing County, the county government and pioneering in the cement market in Zhejiang, the county government, County government and pioneering in the "on accelerating the development of industrial economy of a number of opinions" clearly put forward, to be in the "Tenth Five-Year" period of the elimination of machine kiln cement production, and the removal of machine kiln cement enterprises to give a one-time incentive, each machine kiln demolition incentives 30-50 million yuan.
Promoted by the government, planning to guide, the market decision and enterprise awareness of the multiple forces under the combination of the role of the Changxing County Government only 9.05 million yuan of incentive funds, quietly dismantled the machine kiln 38, small dry rotary kiln 4, large wet rotary kiln 5, two years ahead of schedule in the province's first to complete the elimination of backward cement production methods; at the same time, the construction of 2,500 tons of production capacity and above cement At the same time, 10 cement production lines with daily output of 2,500 tons and above were built, and the production capacity of new dry-process clinker exceeded 10 million tons/year, realizing the goal of building Changxing into a new dry-process cement clinker production base proposed by Economic and Trade Commission of Zhejiang Province. The development of cement industry here has influenced the historical process of structural adjustment of cement industry in Zhejiang.
In this quiet change, the machine kiln cement enterprises here have experienced what kind of ups and downs, there has been what kind of journey, the development of enterprises and how? Not long ago, the reporter made a special trip to make a long-awaited return visit. When we look back and touch this past, can still be from the fate of the intersection of the masses of people, realization and perception of the fate of the interlaced, career ups and downs brought about by the bitterness of sweet and sour.
Life here quietly turned a corner
Lin Song is the deputy general manager of Changxing Baixian Cement Company Limited, and now he has to drive more than 10 kilometers every day to work in a place called Baixian Village, Baixian Township. With the company of the roaring machines, with the surrounding farmland, towering slopes as neighbors, day after day, loud talk, big cups of wine, big bowls of food, big pieces of meat, such a life makes the handsome young man looks more energetic, more energetic, but also more bold.
In 2004, graduated from the University of Lin Song had previously worked in the local Broadcasting Bureau for six years, which is not a unit that can be easily accessed, but also not a job that can be casually say something else. However, Lin Song's father, Lin Yanbao, is very busy, in his management of enterprises in the cement, paint, stainless steel, storage batteries and other industries, enterprises across Jiangsu and Zhejiang provinces. More importantly, the company machine kiln demolition time is also looming. "Tiger pro brother, on the battlefield father and son soldiers", in this dilemma of the turning point, Lin Yanbao naturally played the idea of his son Lin Song.
Prior to this, Lin Song had no intention of getting involved in his father's business, and he could have chosen a steady path in life. But fate intersected his future with his father's career, and his father's call and his inner desire to challenge tradition and hardship led him to choose the life he lives today.
Changxing Baixian Cement Co., Ltd. and the branch plant is located in Baixian Township, about 2 kilometers, *** with φ2.8 × 10, φ2.9 × 10, φ3 × 11 machine kiln each one, the annual production of cement more than 200,000 tons of cement, the year is good when you can achieve the benefits of the very considerable. 1999, Zhejiang Province, Economic and Trade Commission on the adjustment of the structure of the cement industry policy was introduced, with the introduction of new dry-process cement production lines have been put into production. After 1999, Zhejiang Province Economic and Trade Commission's policy on adjusting the structure of the cement industry has been introduced one after another, with the new dry-process cement production line has been put into production, the two market competitiveness of the high and low self-evident.
In line with the idea of early elimination and early initiative, "Baiyan Cement" dismantled three machine kilns in December 2004, through the county government and the relevant departments of the coordination of planning, the original cement industry into two parts of the development. According to the principle of "total amount control and equal amount elimination", they let the index of machine kiln elimination to invest in the construction of new dry cement clinker production line of Xiaopu Zongsheng and Coal Mountain Zongsheng, so that the direction of industrial investment can be optimized. At the same time, "Baiyan Cement", through technological transformation, adopted φ3.2×13m large mill with roller press for joint grinding, and clinker was supplied by our partner "Zongsheng Cement", which built a cement grinding station with an annual capacity of 600,000 tons in 2005, continuing the service to our past cement customers. The cement grinding plant with an annual capacity of 600,000 tons was built in 2005, continuing the service to the past cement customers. After the dismantling of the kiln in the branch plant, the company said goodbye to cement production, and the 40 acres of vacant land was used to set up a small refractory material factory. The government gave nearly a million kiln demolition incentive funds, before and after the investment in the above project. The company's main goal is to provide the best possible service to its customers.
Lin Song is in the grinding station renovation eve left the Broadcasting Bureau to the enterprise, he said with a smile into the plant encountered suffering labor is not words to express, but all of this for him as a pure amateur solid enlightenment, remedial lessons, shorten his integration into the enterprise time. He participated in the technical transformation of the cement grinding station, and then responsible for the production and operation of the enterprise, today's Lin Song managed the cement grinding station head to head. 2006, Lin Song planted 3000 trees on the vacant site, and this year renewed the planting of more than 1,000 trees, so that the former dusty cement plant has become green and lush.
Now it seems that Lin Song's choice may make society less of a mediocre bureaucrat and more of a corporate talent.
Career here quietly turned a corner
There are many times, farewell is a choice, a responsibility, but also a realization.
Zhejiang Xinminghua Building Materials Co., Ltd. is located in Changxing Lijiaxiang, west of National Highway 104. The original is a machine kiln cement, white cement production enterprises, the chairman of the board of directors Wang Xiaoshi is a strong entrepreneurial spirit, but also a reporter's many years of old acquaintances. From 2001 to 2004, the new Minghua building materials **** demolition of three machine kilns, kiln diameter from 2 meters to 2.8 meters. In these four years, Wang Xiaoshi actively looking for new investment direction, especially focusing on environmental protection and comprehensive utilization of resources, they are part of the enterprise facilities for technological transformation, invested millions of dollars to build a fine chemical workshop. The use of 80 acres of land vacated, and recently began negotiations with German businessmen to invest in the construction of 200,000 tons of light calcium carbonate cooperation intention.
"New Minghua building materials," the technical staff of the introduction, the reason why foreigners favor them, lies in the company's attention to environmental protection. They have built an annual output of 80,000 tons of ultra-fine calcium carbonate production line, designed with carbon dioxide exhaust and calcium oxide residue recovery device, can be used to produce calcium hydroxide, part of the calcium oxide residue can also be used for white cement production. Now the water inside and outside the enterprise is clear, the air is fresh, the original sewage enterprise has been transformed into an environmentally friendly enterprise to treat pollution and benefit the waste. The ex-factory price of their activated calcium reaches 750 yuan/ton, light calcium carbonate 560 yuan/ton, and 400 purposes of heavy calcium carbonate is also sold to 290 yuan/ton. Wang Xiaoshi's career has taken a welcome turn in his business development choices and social responsibility.
East of Changxing, at the foot of Bent Mountain, 47-year-old Wang Jinhua, general manager of Huzhou Bent Mountain Building Materials Co., Ltd. was assigned to buy the cement plant in 2000 when Hongqiao Township enterprises were restructured. Enterprise original three machine kilns, a kiln diameter of less than 2.2 meters of machine kilns dismantled in 1999, 2004, 2005 and dismantled the remaining two. During this period, he transformed the enterprise into a grinding station with an annual output of 500,000 tons of cement.
"Bent Mountain Building Materials" original system of quarry enterprises evolved from the plant more disabled people, resettlement is more difficult, the legacy of more problems. Changxing County government at all levels combined with the local mine remediation, environmental remediation along the highway and market changes, in order to solve the difficulties of enterprises, revitalization of land resources, and business consultation with the original approval of 1 million tons of cement grinding station is no longer built, the existing 500,000 tons of grinding station all out of the enterprise can be subsidized by 11 million yuan. Wang Jinhua and shareholders after discussion, agreed to the government's program. Wang Jinhua said that the poor market competitiveness of machine kiln cement enterprises, the impact of environmental pollution is serious, the machine kiln dismantled plant and equipment utilization rate is not high, coupled with the additional burden of the enterprise is too heavy, has lost the future of survival and development. The government through the adoption of the above initiatives, effectively help enterprises to solve the machine kiln demolition brought about by the various contradictions.
Not long ago, "Bent Mountain Building Materials" commissioned the auction company to let all the plant facilities and equipment, and access to auction funds 4.5 million yuan. Wang Jinhua and shareholders intend to build a standard factory on the old site, can be used to rent, but also for their own development of other industries. So far, the enterprise has basically withdrawn from the cement industry, can properly solve the remaining problems.
Industry here quietly on a stage
60-year-old Zhou Shaochang voice, eyes gleaming, looks far lighter than his actual age. As a landmark figure in the cement industry in Changxing and even in the cement industry in Zhejiang Province, he is the only entrepreneur in Changxing County who has experienced the whole process of developing a new dry-process kiln from a vertical kiln to a daily output of 1,000 tons, 2,500 tons, and then 5,000 tons per day. His every choice almost represents a direction, a trend and an inevitability. His life, condensed the process of the historical development of small cement enterprises in China's townships.
Changxing Coal Hill Cement Plant is the ninth in Changxing County, Coal Hill Township, the first machine kiln cement enterprises. 1982, the beginning of the enterprise, due to a lack of funds, the project can not be delayed. 1983 into the plant Zhou Shaochang is the fourth director of the preparation of this enterprise. No technology, no talent, no money, how to do? Local government leaders took Zhou Shaochang to Shanghai to approach the compensation trade, and finally raised millions of dollars in funds, in January 1986 the first kiln diameter of 2.2 meters of the machine kiln was completed. 1988, Zhou Shaochang also raised funds to design their own 50,000-ton annual output of machine kiln cement production line. Through the production, expansion, transformation, through the market weakness, sales several times round, the enterprise after ten years of life gathering development, finally formed in 1994 with 6 vertical kilns, more than 400,000 tons of cement annual output, assets of nearly 40 million yuan of Zhejiang Mountain Eagle Building Materials Group.
In the province's cement enterprises, Zhou Shaochang is known for his knowledge of technology, dare to innovate. The original six machine kiln cement production line, in addition to the first of the rest are designed by Zhou Shaochang's own organization and construction, he was the first in the province to use extruder technology, the first two-stage crushing of raw materials and the vertical breaking process, and he was a joint venture with a foreigner to build the province's first 1,000-ton per day production line of new dry process rotary kiln.
In 1994, 93-year-old Singaporean patriotic overseas Chinese Mr. Lim Kok Yan saw Zhou Shaochang's character and talent, and proposed to cooperate with him *** for development. Foreigners spent 65 million yuan to buy the "Zhejiang Mountain Eagle" 50% of the shares, *** with an investment of 200 million yuan, the construction of a 1,000 tons / day of new dry process rotary kiln cement production line. Although the final investment of 250 million yuan, it took nearly three years to complete the project, but for various reasons, the operating efficiency of the enterprise is not good. 1999, Zhou Shaochang to the board of directors proposed the expansion and transformation, and then on a 2,500 tons / day of new dry-process production line. As a partner of the board of directors of overseas listed companies did not agree to this investment plan, they questioned: already dug a well that did not see water, why dig a second one? Zhou Shaochang, finally convinced the board of directors, only 130 million yuan of funds, 10 months at the end of 2002, the production line will be completed and put into operation, the next year to create a considerable benefit.
At the same time, by Zhou Shaochang financing 150 million yuan of Xiaopu Zongsheng Cement Co., Ltd. 2500 tons / day of new dry-process cement production line was put into operation; the end of 2003, the investment of only 258 million yuan of 5000 tons / day of Coal Mountain Zongsheng Building Materials Co. Zhou Shaochang in 2004, 2500 tons / day of new dry-process cement production line supporting the construction of the first fully localized 3 megawatts of waste heat generator set, to achieve the energy-saving emission reduction of cement production.
"Zhejiang Mountain Eagle" six machine kilns were dismantled before the two new dry-process cement production lines "Zongsheng Cement" and "Zongsheng Building Materials" were built and put into operation, and the enterprise has long gotten rid of the traditional small production mode and become a new enterprise. In 2005, Zhou Shaochang left "Zhejiang Shanying" and retired, now he puts his main efforts on the management of "Zongsheng Cement".
Zhou Shaochang retired from "Zhejiang Shanying" in 2005, and now he puts his main energy on "Zongsheng Cement".
Zhou Shaochang is lucky, he experienced the rise of machine kiln cement, development and elimination, accurately grasped the direction and timing of the development of new dry cement, to achieve the industrial upgrading of enterprises and take off development.
Local economy here quietly on a stage
Zhejiang Zhongxing Building Materials Group Company is the machine kiln cement enterprises in Changxing County, "grandfather", built the county's first cement machine kiln. Started in the seventies of last century, the rise of "five small industries" when the "Zhejiang Zhongxing", from the annual output of 3,000 tons of cement, 5,000 tons has been developed to 150,000 tons of production scale. 1991, they cooperate with Singapore Baolong ash company and other partners, the formation of Zhejiang Xing Baolong Building Materials Co. Ltd., invested more than 60 million yuan to build a 600 tons / day five-stage cyclone preheater kiln, the production line went into operation in January 1994, which is the first township enterprises in Huzhou City, the first cement rotary kiln enterprises.
Although "Zhejiang Zhongxing" cement kiln management is not bad, tons of cement integrated power consumption of 75 kilowatts or less, tons of clinker coal consumption of 140 kg or less, but in 1999 and 2005, they still bear the pain of dismantling the two kilns. Now, "Zhejiang Zhongxing" in addition to the "Xingbaolong building materials", last year also supported the "Xingbaolong building materials" to transform the production line into 1600 / day tons of new dry process rotary kiln, itself The cement industry has completely withdrawn, no longer involved in the production and management of cement enterprises.
Now "Zhejiang Zhongxing" demolition kiln vacated 55 acres of land has been successfully developed new industries. Ltd. covers an area of 30 acres, a project investment of 26 million yuan, the production of calcium carbonate fineness of 1,500 - 5,000 purposes, the second phase of the project for the production line of modified plastic additives. Ltd. with an investment of 18 million yuan covers an area of 20 acres, has been put into production in 2006. The output and benefits of the two new enterprises far exceed the contribution of cement production to local economic development.
According to estimates, Changxing County by the new dry-process cement production to replace a variety of backward production processes, improve limestone resource utilization rate of about five percentage points, dust emissions by half, sulfur dioxide gas emissions reduced by more than 2/3, fluorine and nitrogen oxides, and other harmful gas emissions also meet the national standards, effectively improving the quality of the local air and living environment. Now there are five enterprises using pure low-temperature waste heat power generation technology, annual power generation 147 million kilowatt-hours, equivalent to 18,000 tons of standard coal, according to the calculation of 0.6 yuan per kilowatt-hour of electricity, each ton of clinker can reduce the production cost of about 16.8 yuan, and there are four enterprises plan to complete the construction of pure low-temperature waste heat power generation project in this year and next year. 2006, the cement industry in Changxing County completed profits and taxes of 278 million yuan, a net increase of 22 times more than the structural adjustment of former In 2006, the cement industry completed a profit tax of 278 million yuan, a net increase of 22 times compared with 1998 before the restructuring, and the sustained and optimized development of the cement industry has strongly contributed to the growth of the local economy and the improvement of people's livelihood.
It is worth mentioning here, Zhejiang Three Lions Group gave full play to the leading role in the cement industry, they built the first 2500 tons / day, 5000 tons / day of new dry-process cement production line in the province, for the construction of new dry-process cement production line in Changxing has set a model. 2004 and 2005, the Zhejiang Three Lions Group, Zhejiang Changguang Cement Company Limited, and other provincial enterprises in Changxing. In 2004 and 2005, Zhejiang Three Lions Group, Zhejiang Changguang Cement Co., Ltd. and other provincial enterprises in Changxing took the initiative to dismantle four small dry rotary kilns and five large wet rotary kilns in accordance with the requirements of industrial development and the actual situation of the enterprises.
From the machine kiln to the grinding station, to the new dry process rotary kiln, or completely out of the cement industry after the conversion, Changxing cement enterprises in the local government and the invisible hand of the market under the dual role of the invisible hand, to make their own choices. Although their decision time is not the same, the adjustment process is not the same, the difficulties encountered are not the same, the direction of development is not the same, but they have always insisted on eating through the industrial policy, fit the market direction, relying on the resources of the market, optimize the capital investment in the determination and awareness has not changed, through the local government and the relevant departments dedicated service, troubleshooting, to ensure that the transformation of enterprises to switch to the production and restructuring of the target The company's business has been a great success.
Especially valuable, so a huge machine kiln industry cluster withdrawal, silent, as in a wide lake cast a stone, no sound, only wonderful ripples.
