Light Weight Alumina Heat Thermal Mullite Insulating Refractory Fire Brick for Furnace and Boiler¹

Product Description HJM insulating firebrick is manufactured from high grade refractory powder and materials in good purity. During the process of production, some organic and multiple filling materials are added according to the specific requirement proportion. By compressed in vacuum and sintered under high temperature, the brick has typical advantages including low thermal conductivity, good thermal shock resistance, low heat capacity and low iron content as well as outstanding mechanical flexibility which has extensive applications in variety of industrial markets.Applications Of Insulating Fire BrickNonferrous Metal FurnaceRotary & Shaft KilnVarious IncineratorReheating FurnacePermanent Lining For EAF LadleGeneral Industrial Furnace etc.FeaturesDirect access to fireLow thermal capacityLow thermal conductivityExcellent thermal stabilityExcellent thermal resistanceHigh purity and low iron contentAccurate dimension and easy cuttingDescriptionHJM-23HJM-26HJM-28HJM-30HJM-32 ABC2626A2828AChemical composition(%)AL2O3353745515660657175SIO2555349444036322623FE2O3110.90.80.80.670.650.60.55K2O+NA2O1.41.30.231.21.10.90.80.80.8Physical propertiesDensity(kg/m3)48060080080080090090011001200Classification temperature(oC)120012501300135014301490153016501730Cold rushing strength1.11.22.22.32.52.82.93.54.0Modulus of ruputre0.91.11.21.51.51.81.82.02.1Permanent linear change(%)*24h1150-0.51200-0.31250-0.21300-0.41400-0.41450-0.91500-1.01550-1.11650±1.1Thermal Expansion(%) 1000oC0.50.60.70.70.70.80.850.91.1Thermal Conductivity(W/m.k)         350oC0.130.170.230.230.21----400oC---0.250.220.340.330.380.48600oC---0.260.2350.370.350.40.521250oC---0.280.2650.460.430.480.58As one of the leading manufacturers and suppliers of refractory products in China.Greenergy Refractory& Insulation Material Co., Ltd enjoys close proximity to her customers.During long time in the market, we accumulate a lot of experiences in refractory and insulation materials for Steel plant, Boiler, Cement, Ceramics, Aluminum, Petrochemical and Metallurgy industries as well as other thermal treatment industries.
