Insulation Fire Brick, Firebrick, Refractory Brick
Basic InfoFeature: Long Time MaterialsShape: BrickSize: According to The DrawingSpecification: SGS&ISOHS Code: 69022000Refractoriness (℃): 1580< Refractoriness< 1770Type: Refractory MaterialMaterial: MulliteTrademark: WAMOrigin: ChinaProduct DescriptionMullite insulating bricks characteristics and advantages:1. Lower content of iron,Website:, alkaline and impurities, good high temperature properties.2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.3. High strength, good thermal shock resistance under high temperature.4. Precise sizes due to grinding and shaping after sintering, which meets the requirement of construction.5. Max service temp: Up to 1730C (3160F)Physical and Chemical Properties of insulating brickIndex /brandWAM-20WAM-23WAM-25WAM-26WAM-28WAM-30WAM-32Classification temperature o C F Bulk density kg/m Ib/ft .56478Modulus of rupture MPa 0.70.91.41.51.61.72Ib/in Cold crushing strength MPa 1.21.22.02.02.62.83.4Ib/in 2 Permanent Liner Change % -0.1-0.1-0.5-0.5-0.8-0.9-0.9o C x hour1230X241230X241350X241400x241510x241620x241730x24 400 o C0.170.170.240.240.300.400.49Thermal conductivity600 o C0.190.190.280.270.320.420.50(W/m. k)800 o C0.220.220.320.300.350.440.511000 o C0.240.250.370.320.380.450.531200 o C -- -- --0.350.390.470.55Al2O3 %Fe2O3 %0.70.70.650.60.30.30.3SiO2 %TiO2 %1.31.21.31.10.90.50.3CaO+ MgO %0.50.70.60.30.20.30.2K2O+ Na2O %1.01.31.11.10.80.20.1The above datas are subject to normal manufacturing variations and change without notice.
