new type light weight mullite refractory

1.Definition It is the new type quality thermal insulating refractory material, and alumina contents from 50%-85%, and make (3Al2O3.2SiO2)as major phases and binder phase mullite. Working temperatures are from 1350°C to 1700°C.2.Features:1).High strength of high temperature structure2).Low creep rate at high temperature3).Low thermal expansion rate4).Strong resisting chemical erosion performance.5).Fine resisting thermal shock performance.6). ISO 9001:2000 Certificate. 7).Packing: wooden pallet, plastic film wrapped, steel fiber. 3.Property ITEM HXP40-10 Properties Al2O3 % ≥55 Fe2O3 % ≤0.8 Bulk density g/cm3 ≤1.0 Cold crushing strength MPa ≥3.5 Thermal shock Stability (1100°C, cold air) Times 20 Thermal conductivity (w/m×K) (350°C) 0.33 Linear Change rate is on reheating (1400°C, 12H) % ≤1 4. Application: Made as the working lining of directly contacting flame furnace to improve saving energy effect of the furnace.
