Details Introduction
Corundum castables include corundum castables, corundum plastic materials, corundum ramming materials, and corundum wear-resistant materials. Corundum products are made from refractory materials with an Al2O3 content greater than 90%, primarily composed of corundum as the main crystal phase, and are compounded with appropriate amounts of dispersants, accelerators, stainless steel fibers, according to strict formulations. They have many characteristics such as good high-temperature strength, wear resistance, high thermal conductivity, thermal shock resistance, corrosion resistance, good sealing properties, and early strength. The products are widely used in circulating fluidized bed boilers, metallurgy, petrochemicals, thermal power, and other industries.
