Wear resistant castables mainly refer to castables with good wear resistance at room temperature and specific temperature. The determination of wear resistance of wear-resistant castables at room temperature can be determined according to the test method for wear resistance of refractory materials at room temperature. The smaller the amount of wear , indicating that the wear resistance of the castable is better.

In the cement clinker firing system, wear resistant castables are mainly subjected to severe wear from cement raw meal, clinker or dust-containing high-temperature gas, so the raw materials selected for wear resistant castables must have the characteristics of high bulk density and high mechanical strength. Such raw materials mainly include fused corundum, sintered corundum, fused corundum, silicon carbide, silicon nitride, etc. In addition, in order to improve the durability and wear resistance of the material, it is generally necessary to add heat-resistant steel fibers.

Wear resistant castable is suitable for large and medium-sized cement kiln front kiln mouth, coal injection pipe, tertiary air pipe elbow, gate, grate cooler throat and other parts
