What are the technical requirements for the wear-resistant ceramic sheet of the coal mill?

2022-02-25
 Latest company case about What are the technical requirements for the wear-resistant ceramic sheet of the coal mill?

The wear-resistant ceramic patch is a special corundum ceramic made of 95% AL2O3 as raw material, rare metal oxide as a solvent, and sintered at a high temperature of 1700 ° C. According to the different operating conditions of the equipment, suitable wear-resistant ceramics are selected, to satisfy the customer's request.

 

Wear-resistant ceramic patches are widely used in relevant equipment and pipelines of coal powder transportation in power plants, sintering and dust removal in steel plants, cement plants, etc. The performance of wear-resistant ceramic sheets on the inner wall of coal mills is as follows:

Wear resistance: The content of Al2O3 in the ceramic layer of the ceramic composite steel pipe is more than 95%, and the microhardness is HV1000-1500. It has extremely high wear resistance, and its wear resistance is more than ten times higher than that of quenched medium carbon steel. Better than tungsten drill carbide.

 

Corrosion resistance: Ceramic is a neutral material with stable chemical properties, excellent corrosion resistance, and acid resistance, and can resist various inorganic acids, organic acids, organic solvents, etc., and its corrosion resistance is more than ten times that of stainless steel. 

 

Excellent heat resistance: The operating temperature of the on-site equipment must be determined before the construction of the wear-resistant ceramic patch, and the viscose with different temperature resistance should be selected at different temperatures, otherwise the wear-resistant ceramic chip will easily fall off as the temperature rises.
