Refractory Castable

Detailed Product Description

This picture shows refracotry castable in woven bag and jumbo bag. The type is alkali-resistant refractory castable HA-40. This type has the same density and working temp with A-40, but the strength is much higher.

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.
