What are the applications of wear-resistant ceramic sheets in pulverized coal pipelines?

 Latest company case about What are the applications of wear-resistant ceramic sheets in pulverized coal pipelines?

The elbows of the pulverized coal transportation pipelines of thermal power plants are particularly worn and have long been the key parts of power plant maintenance. The service life of the pipelines is directly related to the operating costs and economic benefits of the entire power plant. From the wear resistance, high temperature resistance and corrosion resistance of the pipeline Considering the convenience of function and construction, the application of wear-resistant ceramics in pipes can fundamentally solve this problem.

 

The wear-resistant ceramic sheet uses AL2O3 as the main raw material and is a special corundum ceramic produced by calcining at a high temperature of 1700 Baidu. Its Rockwell hardness is HRA80-90, the hardness is second only to diamond, which can greatly extend the service life of the elbow of the pulverized coal pipe.

 

The wear-resistant ceramic commonly used in the wear-resistant elbow of the pulverized coal pipeline adopts the welding process with a hole in the middle, and is equipped with a steel bowl and a porcelain cap. The construction of this wear-resistant ceramic sheet is also more convenient. The ceramic sheet is directly welded to the steel body, and the overall appearance is all ceramic surfaces. This further strengthens the firmness of the ceramic sheet pasted on the pulverized coal pipe. The advantage of this type of ceramic patch is that it is easy to repair and maintain. Even if the pipeline is worn during operation, it can be directly repaired, saving manpower and material resources.

 

Wear-resistant ceramic sheets are used in various industrial wear environments, such as wear-resistant and anti-corrosion of fan impellers and casings. Wear-resistant ceramic sheets are also often used to compound wear-resistant pipe elbows with various metal materials. The wear-resistant ceramic sheet can also be used in the wear-resistant and wear-resistant of various types of water pumps, slurry pumps, circulating water pumps, impellers and various overcurrent components.
