Refractory Castable for ladles

Detailed Product Description

The picture showing above is refractory castable for ladles in jumbo bag, high Alu-spinel A-70 type. The chemical content is Al2O3 70% and MgO 8%.

Double Egret is the specialized manufacturer and exporter of refracotry and insulation material in north of China. Our products mainly include refractory castable, refractory brick, insulating brick. For refractory castable, Double Egert has the production capacity 500tons per month, primarily export to USA, AUSTRALIA, RUSSIA, JAPAN, GREECE etc.

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.
