The main mineral composition of chrome corundum brick is α-Al2O3-Cr2O3 solid solution. The secondary mineral is a small amount of composite spinel (or without composite spinel), and the content of chromium oxide is 1% to 30%. There are casting chrome corundum bricks and sintered chrome corundum brick. Under normal circumstances, chrome corundum brick refers to the sintered chrome corundum brick.


At present, the application of chrome corundum brick made of chromium metal slag are widely used in zinc smelting furnace, volatile kiln. Chrome corundum brick has excellent thermal vibration stability and high temperature creep performance; at the same time meet China’s national requirements of circular economy.




The chrome corundum bricks made by Zhengzhou Jinshi Refractories Co., Ltd. Takes corundum and fused oxide chrome as the main raw material, together with the powder and other additives, and treated by mixing, molding, drying, firing at shuttle kiln.


Products are with features of wear-resistant, heat shock, acid and alkali erosion. High chromium brick (Cr2O390%) is mainly used in coal chemical industry, chemical industry kiln, alkali glass fiber furnace, garbage incinerator and other key parts of the kiln; While chrome corundum brick is mainly used for carbon black furnace, copper smelting furnace lining, the glass furnace molten pool, rolling steel furnace slideway and tapping platform.
