Introduction of refractory castable
In refractrory world, there has many kinds of castable. Different castable has its own features and application, they are important to kiln, furnace and other thermal equipment.
Castables has high alumina low cement castable, sic castable, corundum castable, alumna steel fiber castable, alumina self flowing castable, corundum mullite castable, mullite castable, wear resistance castable, clay castable, etc.
We use Steel fiber reinforced refractory castable as example.
Steel fiber reinforced castable is made up of high aluminum bauxite clinker as aggregate, high quality bauxite clinker as matrix, various composite materials such as ultrafine powder as binder and additive, plus heat-resistant stainless steel fiber.

Refractory Castable Physical and Chemical Features
1.High mechanical strength
2.Good thermal shock resistance
3.Good toughness and anti-stripping
4.High refractoriness
5.Tiny linear variation,no cracking
6.Resistant to scour and erosion
7.Good volume stability under high temperature

Refractory Castable Physical and Chemical Application
Steel fiber reinforced refractory castable is mainly used in heat treatment furnace,heating furnace,soaking pit furnace,tundish slag dam weir,seconclary refining and the catalytic cracking unit etc key part of kiln furnace and thermal equipment.
