High quality industrial furnace used chrome brick
Chrome brick, based on corundum and fused chromium oxide as the main raw materials, with micro-powder and other additives, through mixing, molding and drying, are made by baking at high temperature in shuttle kiln.
It is characterized by high temperature, good corrosion resistance, thermal shock and bulk stability under high temperature etc .
