High Alumina Castable Introduction
High Alumina Castable is a kind of refractory castable which uses high alumina raw material as aggregates and the powder and then be added with binding agent. High aluminum refractory castable has high mechanical strength, good thermal shock resistance, good corrosion resistance. It's mainly used for furnace lining of boiler, blast furnace hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.
Application of High Alumina Castable
High Alumina Castable also called calcium clinker, is made from industrial alumina oxide powder and selected limestone powder. It is produced after manufactured under high temperature in rotary and grind into powder. The product is for making high quality refractory castables, which is a dispensable tool used in high temperature facilities in industries like metallurgy, building material, chemical, electric plant, etc.
