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 mixed with appropriate amounts of dispersants, coagulants, stainless steel fibers, and strictly formulated composites. They have many characteristics such as good high-temperature strength, wear resistance, high thermal conductivity, thermal shock resistance, corrosion resistance, good sealing, and early strength. The products are widely used in industries such as circulating fluidized bed boilers, metallurgy, petrochemicals, and thermal power.
