Castable refractories are material that contain precision-graded fine and coarse refractory grains. They are gelled with the help of a binder system in the material's green state. After the material is heated, the binder either changes or volatilizes allowing the formation of a ceramic bond. High Alumina Cement (HAC) is the most typical binder used in castables. Other binders that are commonly used include colloidal silica and hydratable alumina.

Our high alumina refractory catables are made from selected high quality aggregates and binder after optimized its ingredients, the product has many advantages including abrasion resistance excellent high temperature performance, erosion and corrosion resistance, etc.

High alumina refractory castables are widely applied in high heat industries. Specifically, they are used in building power plant, blast furnace, melting furnace, heating furnace, soaking furnace, heat treatment furnace and induction furnace in different parts.

Castables are bonded with water and then set up by either pumping or pouring. Vibration is needed to place the material.
