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, 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                                   1230126013501430154016501760F                 2246230024622606280430023200Bulk density   kg/m 352058080080089010301250Ib/ft 33236505055.56478Modulus of rupture    MPa                               0.70.91.41.51.61.72Ib/in 2102131203218232247290Cold crushing strength   MPa                       1.21.22.02.02.62.83.4Ib/in 2          174174363348377406493Permanent 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   %45454555657276Fe2O3    %0.70.70.650.60.30.30.3SiO2     %50505042332622TiO2    %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.
