Zirconia Corundum Brick Introduction
RONGSHENG zircon corundum brick is made of a-Al2O3, ZrO2 and zirconium corundum clinker as materials ,zircon corundum bricks is produced by mixing, molding, drying and sintering at high temperature in shuttle kiln.
Zircon corundum refractory brick are the most widely used materials both in glass contact and superstructure of glass melting furnaces. Refractory products have passed the ISO international certified, are made of high pure material, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity, good erosion resistance and so on. Refractory zirconia corundum fire brick is widely be used for linings of furnace in industries.
