Gongyi Jinshi Refractory Co., Ltd.
The main mineral composition of the steel groove platform brick is α-Al2O3-Cr2O3 solid solution. The secondary mineral composition is a small amount of composite spinel (or without composite spinel), the content of chromium oxide 1% to 30%. There are casting chrome corundum bricks and sintered chrome corundum.
At present, the application of steel groove brick has a wider application, one kind is made of metal chromium slag as the main raw material called chrome corundum bricks, widely used in zinc smelting furnace, volatile kiln, chrome corundum brick Has excellent thermal stability and high temperature creep performance, at the same time in line with the requirements of national recycling economy.
