Product Description

Wholesale Price Unshaped Refractory Material High Quality Refractory Castable for Kiln Furnace
Refractory castables refer to a mixture of refractory aggregates, binders and admixtures, which are mixed with water (or liquid binders) to form a mud material that can be constructed by pouring. The difference from other amorphous refractory materials is that refractory castables have a certain coagulation and hardening time after construction, so after pouring and forming, they need to be cured for a certain period of time before demoulding, and then after a suitable period of natural curing, they can be put into baking and use.

Classification: Low Cement/High Strength/Light Weight

Low cement castables refer to new castables with very little cement binder. The cement content of refractory castables is generally 15% to 20%, and the cement content of low cement castables is about 5%, and some are even reduced to 1% to 2%.

High strength wear-resistant castable is composed of high strength aggregate, mineral admixtures, high strength aggregate and anti crack and wear-resistant agent.

High alumina castables are refractory castables made of high-alumina raw materials as aggregates and powders, and added with binders.

The lightweight castable with low bulk density is made of aluminate cement, high alumina fine material, ceramsite, and additives.
