Technical requirements for electric field ash conveying wear-resistant pipeline? 1, production process:?
Self-propagating ceramic composite steel pipe is made by advanced self-propagating high temperature centrifugal synthesis process. The pipeline consists of corundum ceramics, transition layer and steel body from inside to outside. The ceramic layer is a dense corundum ceramic formed at a high temperature above 2200 degrees, which is firmly combined with the steel pipe through the transition layer. ?
The process adopts the method of self-propagating centrifugal casting, which mainly uses the chemical reaction of the substance itself to generate high temperature through exothermic combustion and synthesize new substances during the propagation of combustion waves. 2. Performance characteristics:?
Good wear resistance, the lining is made of corundum porcelain (AL2O3), and Mohs hardness > 9.0 is equivalent to HRC > 90, so it has high wear resistance to any medium transported by electric power, metallurgy, mining, coal mine, chemical industry, etc., and its service life is more than 10 times that of ordinary steel. Because the lining is corundum porcelain (AL2O3), the crystal structure is single and stable, so it is between-50 and-50. The linear expansion of the material is 6~8× 10-6/℃, the inner surface of the composite steel pipe is smooth, the running resistance is low, and it has comprehensive properties such as corrosion prevention and scale prevention, and the welding performance is good. Direct welding, flange connection and quick pipe joint can be adopted, which is very convenient for construction and installation. 3. Wide application:?
Because of its wear resistance, corrosion resistance and heat resistance, the pipe can be widely used in electric power, metallurgy, mining, coal, chemical industry and other industries, and it is an ideal wear-resistant pipe as an abrasive granular material and corrosive medium for conveying sand, stone, pulverized coal, ash and aluminum liquid. ?
Application of 1 in metallurgical power industry? Metallurgical and electric power industries need to consume a lot of metal pipes to transport pulverized coal, ash and mud every year. Replacing other pipes with ceramic composite pipes has the characteristics of high wear resistance, long service life, convenient installation and remarkable economic benefits, and its service life is ten times or even dozens of times that of steel pipes.
