Main mineral composition of Chrome aluminum brick is α-Al2O3-Cr2O3 solid solution. Secondary mineral composition: a small amount of composite spinel (spinel or without compound), chromium oxide content of 1% to 30%.
Chorome bricks can be cast chromium corundum brick and fired brick. Under normal circumstances, chrome corundum bricks refer to sintering chrome corundum bricks.

At present, aluminum chrome bricks have a wider application, chrome corundum bricks made of chromium slag are widely used in zinc smelting furnace, the volatile kiln, chromium corundum brick has excellent thermal stability and high temperature creep vibration performance while meeting national recycling economy.
The main material of chromium corundum brick made by Jinshi Refractory are corundum and fused chromium oxide with powder and other additives. After kneading, shaping, drying, high temperature fired in shuttle kiln. The product has the characteristics of wear-resistant, anti thermal shock and acid erosion.
High chrome brick (Cr2O3≥90%) is mainly used at the key parts of kilns in coal chemical industry, chemical industry, E-glass fiber furnaces, waste incinerators, and other kiln; Chromium corundum brick is mainly used in carbon black furnace, copper smelting furnace lining, glass furnace bath, rolling furnace chute, tapping platform. Product dimensions, physical and chemical indicators and service life have reached or exceeded the level of similar products at home and abroad.
