Several High Temperature Resistant Components in High Temperature Castable Refractory
In the working lining of various kilns, the kiln mouth and coal injection nozzle of the new dry-process cement kiln are subject to strong high-temperature seismic erosion and serious wear and tear, and high-quality uncertain refractory materials are required. Generally, high temperature castable refractory for cement kiln contains corundum, mullite, andalusite, silicon carbide minerals. Next, several high temperature resistant components of high temperature castable refractory will be analyzed. High Quality H igh T emperature C astable R efractory Corundum C omponents Corundum is divided into sintered corundum and fused corundum. Among them, fused corundum is a product obtained by melting alumina or bauxite in an electric furnace and then cooling. The fused corundum has large grains, high density, low porosity and high hardness. The sintered corundum has small grains, many pores and small hardness, but it has good thermal shock resistance. Generally speaking, cor...
