Detailed Product Description
The photo shows high strength refractory casatable in woven bag package. This is the corundum type, with the Al2O3 93%. The max work temp is 1750oC.
Double Egret is the leading manufacturer and exporter of refractory and insulation material in north of China. The main products include refractory castable, refractory brick, insulating brick etc.
CCE WOOL refractory castable is unshaped refractory material that doesn't need firing and features fluidness after adding water. Mixed by grain, fines and binder in fixed proportion, refractory castable can replace special shaped refractory material. Refractory castable can be used directly without firing, easy to construct, and has a high utilization rate and high cold crushing strength.
Refractory castable is primarily used for furnaces and kilns in metallurgy, petroleum, chemical industry, construction, electric power and machine building.
