The metallurgical industry is one of the industries that currently uses the most refractory materials, accounting for more than 60% of the weight of refractory consumption. Refractory material is also an important basic material in the nonferrous metal metallurgy industry, and is the main recipient of high temperature melt physicochemical erosion and mechanical damage. At present, the refractory materials used in the non-ferrous metal industry mainly include magnesium-chromium refractory materials, silicon carbide refractory materials, bauxite corundum refractory materials and silicon-aluminum refractory materials.
