Chrome-corundum brick

Chrome-cornt brick has such characteristics, as high fire resistance, high strength, high refractoriness under load and excellent thermal shock resistance. It has good corrosion resistance to other slag, slag for non -ferrous metal smelting, slag for coal gasification and various glass melts.

The process of production of chromium brick chromium

Al2O3 is used as raw material, By adding the corresponding amount of chromium oxide powder and fine powder of chromicurundum clinker after molding and firing at high temperature. The content of chromium oxide in seduced chromicurundic bricks is usually lower, than in melted cast chromacrunt bricks. It can also be prepared by pouring suspension. Mix Al2O3 powder and chromium oxide powder evenly, add baking powder and organic binder, to make a thick suspension, at the same time add part of the chrome-corundum clinker, make bricks using the grouting method, and then burn.

Application of chrome-corundum bricks

Chrome-corundum bricks are resistant to high-temperature oxidation and corrosion and are used in ferrous metallurgy and foundries, petrochemical industry, for lining glass furnaces, porcelain ovens, slag disposal tanks for immersing slag, etc..
