Geringes Gewicht hohe Tonerde isolierende Verblender

Light weight high alumina Insulating brick Material And Technic This series ofinsulating bricksare made of high grade bauxite, kaolin clay as the main material. Produced by our licensed technology shaped by casting sintered at high temperature been cut and polished to the demand sizes. ApplicationThey are widely used in petrochemical, machinery, ceramic industry, as insulating linings of various industry furnaces(for example:high furnace, hot blast furnace, coke oven, tunnel kiln, roller hearth furnace, carbon furnace, calcining furnace, lime kiln)where no high temperature melt corrosion occurs.The maximum service temperature is 1400°C.Type Bulk Densityg/cm3Cold CrushingStrengthMpaPreheating Liner Change≤2% at °cThermal conductivity(350±25°C)≤W/m.kDFLG-1.0≤1.0≥101400°C0.35DFLG-0.9≤0.9≥81400°C0.32DFLG-0.8≤0.8≥71400°C0.26DFLG-0.7≤0.7≥61400°C0.25DFLG-0.6≤0.6≥3.51400°C0.18DFLG-0.5≤0.5≥2.51300°C0.17DFLG-0.4≤0.4≥2.51300°C0.15Al2O3 % ≥48Fe2O3 % ≤2.0
