Chrome bricks are made of fused corundum, fused oxidation and zirconia as the main raw materials, with a variety of oxide micro-powder additives. After CNC intelligent mixing configuration, molding, drying, the final step is high temperature firing in a shuttle kiln.
Wear resistance
Thermal shock resistance
Resistant to acid and alkali corrosion
High-chrome bricks are mainly used in the key parts of the furnaces for coal chemical industry, chemical industrial, alkali-free glass fiber and garbage incinerator,etc. Chromium-corundum bricks are mainly used for the linings of carbon soot furnace and copper smelting furnace, the skid rail molten pool of glass furnaces, and tapping platform of rolling mill furnace. Chrome-Corundum can also be used as superstructures and burner blocks for insulating fiber glass furnaces.
