The wear-resistant ceramic sheet is a special corundum ceramic made of AL2O3 as the main raw material, rare metal oxide as the flux, and calcined at a high temperature of 1,700 bai. It is a high wear resistance material, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron.
Not only does it have good wear resistance, it also has the characteristics of high hardness. Its Rockwell hardness is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel. The weight is much lighter than steel, which can reduce the load on the equipment. It is widely used in coal handling, material conveying system, pulverizing system, ash discharge, dust removal system and other mechanical equipment of thermal power, iron and steel, smelting, machinery, coal, mining, chemical, cement, port terminals and other enterprises.
How long the specific wear-resistant ceramic sheet can be used depends on the working conditions. Its service life depends on the size, concentration, impact speed, working temperature, and friction of the conveyed particles. Generally speaking, the smaller the particle, the lower the concentration, the smaller the impact force, and the longer the service life of the wear-resistant ceramic sheet.
Under the working conditions of conveying slag powder, 20mm wear-resistant ceramic sheets can generally be used for 8-10 years. In the pipeline conditions that transport bulk materials, wear-resistant ceramics may be worn off in less than half a year. Therefore, it is necessary to choose different wear-resistant ceramic products according to different working conditions.
