Thisproduct made of ZHONGNAI No.5 material is a prefabrication product. Advantage: excellent heat preservation ,thermal shock resistance ,resisting scour from aluminium and aluminium alloy fusant, high strength, mechanical strike resistance , standard finished size. In the processing of round bar and square bar casting, allocated pouringbox can stable surface of the fusant and support the lauder make fusant transmitting in the same level reducing the second impurity before casting. Besides general specification, we offer products according customers' requirementPS: Form A ZHONGNAI material physical capabilityWorking temperatureDensityTortuous intensityPressure resistance intensityCoefficient of heat conductivityHeat linear shrinkageCoefficient of heat expansionoCg/cm3kg/cm2kg/cm2700oC (w/m·k)800oC(%)700oC(×10-8oC)≥10000.6-2.5≥50≥105≤0.2≤0.3≤2.77Form B ZHONGNAI material chemical compositionSi O 2AL2O3Fe2O3CaOMgOTiO2K2ONa2O52-5542.50.880.411 21.70.51
