Product description

The main mineral composition of aluminum chrome brick is α-Al2O3-Cr2O3 solid solution. The minor mineral composition is a small amount of compound spinel (or not containing compound spinel), chromium oxide content of 1% ~ 30% refractory brick. There are two kinds of cast chrome corundum bricks and sintered chrome corundum bricks. In general, chrome corundum brick refers to sintered chrome corundum brick.

Chrome corundum brick is mainly used in the lining of carbon black furnace, copper smelting furnace, glass furnace melting pool, steel rolling furnace slide, steel platform. Product size, physical and chemical indicators, service life has reached or exceeded the level of similar products at domestic and abroad.
