Making the localization of bell-less furnace tops more solid
Remembering Xu Zhendong, the director of the Furnace Top Research Institute of Qinye Heavy Industry Co.
Xu Zhendong, the director of the Furnace Top Research Institute of Qinye Heavy Industry Co. Since his graduation, he has been committed to the technological innovation of major metallurgical equipment, especially the bell-less furnace top equipment, and has made gratifying achievements.
Looking back to the past, step by step towards maturity and perfection
In 1998, Xu Zhendong began the development and design of complete sets of bell-less top equipment for blast furnaces under the guidance of famous masters, and participated in the whole process of designing, manufacturing, assembling, and debugging of the first set of domestically produced bell-less top equipment, and successfully launched the first set of commercialized bell-less top equipment with the independent intellectual property rights in China with his team in 2001. The first set of commercialized bell-less furnace top equipment with domestic independent intellectual property rights was successfully launched with the team in 2001. This set of equipment once used in Fujian Sanming Iron and Steel Plant, that created three days to reach the design output target. Breaking the monopoly of foreign companies in the market of bell-less furnace top.
In the process of designing the complete set of bell-less top equipment, Xu Zhendong and his team used three-dimensional software to carry out solid design, and used analysis software to carry out stress and motion simulation analysis to minimize the risks in the manufacturing process of the test prototype. So that the prototype manufacturing a success.
The fabricator is the core component of the bell-less roof equipment, its service life is very critical, the service life of a generation of furnace age is guaranteed to be more than 10 years, in order to ensure the service life, Xu Zhendong and his team, whether from the structural design or the choice of materials have been fully considered. For example, the ring guide device by sliding friction into a rolling friction. This reduces the possibility of the ring being skewed and jammed to zero. Fabricator water cooling initially used a ring pipe spray cooling, due to the cooling water is hard, sometimes there are sand and other impurities in the water, often leading to spray pipe blockage. For this problem we formed a research group, after in-depth investigation and analysis, completely changed the structure of the cooling waterway, and no more cooling waterway blockage.
"Everything comes from practice, everything comes from the field". This is a phrase Xu Zhendong often said.
The most critical part of the service life of the bell-less furnace top equipment is the wear-resistant liner in contact with the charge, according to the wear and tear of each part and the importance of the degree of choice of different materials, take the high chromium cast iron liner, good quality can be used for a year, and poor quality is three or four months, in order to solve the problem of the quality of the liner, Xu Zhendong together with the relevant experts to an outsourcing manufacturer, and the In order to completely solve the problem of liner quality, Xu Zhendong, together with relevant experts, went to an outsourcing manufacturer and signed a technical agreement with it, and carried out the whole process of monitoring such as batching, melting, pouring and subsequent heat treatment, and finally found the optimal material ratio composition and pouring temperature as well as the process of heat treatment, so that the quality of the liner meets the requirements of the drawings, and won the praise of the users.
Xu Zhendong believes that knowledge creates wealth and innovation can develop enterprises. If an enterprise does not have independent intellectual property rights of the core products, it will not have good development. At present, Xu Zhendong has already declared the improvement and innovation of the key parts of the furnace top as a national patent. So far, Xu Zhendong has participated in more than 20 projects of double bell top equipment renovation and new blast furnace bell-less top equipment, and has designed, developed, manufactured, assembled and guided the on-site installation and commissioning of more than 20 sets of bell-less top equipment, which is a solid step towards the localization of bell-less top.
February 2007, Qinye Heavy Industry, complete sets of bell-less top equipment to the international market, exported to Turkey, Indonesia and other countries in Asia and Europe; Xu Zhendong and his team produced and supplied three sets of 2,500 cubic meters of blast furnace bell-less top, as the director of his team will lead the team to the larger level of the blast furnace bell-less top complete sets of equipment to move forward step by step. He will make due contribution to the splendor of the domestic bell-less top business. In the same year, Xu Zhendong led his design and R&D team to investigate the use of 3000~4000 cubic meters level blast furnace and accumulated a lot of on-site information, which laid a foundation for entering the market of bell-less top of blast furnace at this level. Throughout the process of R&D and market recognition of bell-less top equipment of Qinye Company, we can see that the technology is improving, the market is expanding, and step by step, it is becoming mature.
With high quality, defining the connotation of product quality
2009 is the year of quality improvement for QMC, and all the staffs are involved in the activity of improving quality. Taking advantage of this opportunity, Xu Zhendong discussed with his team the technical key of the furnace top sets and the problematic points that are prone to occur, so as to make the quality consciousness deep in the heart of every employee. At present, Xu Zhendong, who is striving for the project of bell-less top of 5800 cubic meters blast furnace of a certain plant, said confidently, "We have reason to believe that a product, as long as the technology is mature and excellent, can be applied to how big the blast furnace is".
The quality of the product determines the future of the company. The wear-resistant material used in large quantities in the top of the furnace without material bell is high-chromium cast iron, and it has been difficult to meet the design requirements after casting of this material. Xu Zhendong, in-depth and extensive cooperation with institutions, through the cooperation with the Chinese Academy of Sciences, Shenyang Institute of Materials, together with the foundry investigation, sampling and analysis, and ultimately succeeded in solving the problem of the casting quality, so that the product quality has reached a new level.
With good service, to win the trust of customers
In the efforts to do a good job of product quality at the same time, increase the site technical guidance and problem handling. Xu Zhendong led his team before and after the depth of Cheng Steel, Tiantie, Longgang, Heilongjiang Jianlong, Xilin and other large-scale iron and steel enterprises to provide technical guidance. In the detailed inspection of the installation equipment before the opening of the new No. 4 2580 blast furnace of Chengshan Steel, the hidden danger of gas leakage after the opening of the furnace due to the deformation of the flange was ruled out in time, so that the opening of the blast furnace was completed smoothly at one time. Successfully solved the problem of frequent breakdown of water seal on the top of 1280 blast furnace of Longgang. Heilongjiang Jianlong used our company's bell-less furnace top equipment for the first time, and has not yet mastered the operation skills of digital cylinder fabricator and digital cylinder throttle valve. In order to eliminate the problems caused by improper operation of the user, in the early stage of equipment installation, the company's roof research institute sent technicians to the scene several times to explain and actually use the training, so that the user can effectively master the operation of the equipment, which has really won the user's recognition and praise.
Xu Zhendong and his team use the best quality to satisfy customers; use the best service to win customers; use the most sincere heart to move customers, they are using practical action to interpret the Qinye people "customer-centered" corporate values, they are full of enthusiasm to meet the challenges, and actively contribute to the leapfrog development of Qinye Heavy Industry. They are embracing the challenges with enthusiasm and actively contributing to the leapfrog development of Qinye Heavy Industry.
