Refractory Castable

Refractory Castable is one type of monolithic refractory materials, which is made of multiple aggregates and one kind or multiple kinds of adhesives. When using refractory castable, match with liquid through stiring. Refractory Castable is featured with high refractoriness, liquidity and plasticity, and can be used in the thermal equipment of metallurgy, chemical industry, petroleum, and light industry.

Refractory Castable for Sale

Refractory castable for sale is a kind of special refractory materials. Compared with the other monolithic refractories, refractory castble has its own properties. This refractory material has more binders and water, so it has good fluidity and thixotropic properties. As a kind of refractory mortar, it is conveniently used in the way of pouring at high heat, or being made into prefabricated blocks, because it doesn’t need heating before use.

According to its properties and functions, these refractory castables can be classified into insulation castable, high alumina concrete, low cement castable(LCC), steel fiber castable, and so on. Based on the chemical properties, it can be classified into alkaline castable, neutral castable, and acid castable. Magnesium or calcium is the main chemical composition of the alkaline castable, which can be used at the environment where a lot of alkaline gasses or slags are produced. Alumina or carbon is the main component in the neutral castable, which is used in all of the high heat environment, because it can withstand either acid or alkaline atmosphere, such as the corundum castable. As for the acid resistant concrete, silica is the most represented material. Such castable can be used in the acid environment.

Attentions: Refractory Castable needs regular repairs, because it maybe splits because of the erosion of the slags or thermal shock.
