Corundum brick is a kind of super grade refractory. From the view of chemical composition, the biggest difference from normal high alumina brick is the Al2O3 content is above 90%. The most advantage features are high compressive strength around 340Mpa, and higher refractoriness under loading up to 1700℃. The specification makes it with good chemical and mechanical stability, and well performance on withstanding the acid or basic slags, metal and glass liquid, etc.
Application:
Corundum brick is widely used in the high temperature, high pressure, severe working conditions, like the area with seriously chemical erosion and mechanical abrasion heat-treatment refractory lining materials. It is widely used for the blast furnace, and hot blast stove, slide gate and glass furnace, and petrochemical industry, and other industrial heat equipment.
