Product Description
Product Overview:
Fused cast zirconia corundum brick is based on industrial alumina powder and zircon sand. After mixing, it is added to an electric arc furnace to melt, cast, anneal, process, and preassemble into a kiln. According to the content of zirconia: 33 #, 36 #, 41 #. According to its casting method, it is divided into four types: ordinary casting PT, inclined casting QX, quasi non-shrinkage casting ZWS, and non-shrinkage casting WS.
