Detailed Product Description

The above photo shows refractory castable in jumbo bag. This casable is Alkali-resistant refractory castable A-48. This type can work at the temp 1300^oC.

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.
