white and sintered corundum refractory brick

Product Description:

Our white corundum refractory sintered products imported tabular corundum brick, high purity fused corundum as main raw materials, the application of superfine powder with advanced technology, after mixing, molding, drying, in shuttle kiln high temperature burn becomes.Sintering white corundum brick with high refractoriness, good thermal shock resistance and high temperature strength, strong corrosion resistance, slag resistance and small expansion coefficient, low creep and spalling resistance, suitable for all kinds of atmosphere under the condition of high temperature furnace use;Sintering white corundum brick is widely applied in zirconia ceramics, fluorescent material, electronic ceramics, magnetic materials, ceramic powders of high temperature sintering and petrochemical industries gasifier, 2 of ammonia conversion furnace, carbon black reactor, glass industrial furnace equipment, etc.Appearance size, physical and chemical index of the products, service life have reached or exceed the level of similar products at home and abroad.
