DETAILS

High-chromium bricks (Cr2O3≥90%) are mainly used in key parts of coal-fired chemical, chemical industry kiln, alkali-free glass fiber kiln, garbage incinerator, etc.; chrome corundum brick is mainly used in carbon black furnace and copper smelting furnace. The lining, the molten pool of the glass furnace, the slide of the rolling steel heating furnace, and the tapping platform. The appearance size, physical and chemical indicators and service life of the products have reached or exceeded the level of similar products at home and abroad.
