High Alumina Refractory 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.
Characteristic of High Alumina Castable
1.Has a certain degree of corrosion resistance;
2.High refractory temperature and high load softening temperature;
3.High compressive strength and excellent thermal shock resistance;
4.High density, low porosity.
5. Good resistance to flake performance.

Application of High Alumina Refractory 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.
Packaging: 25kg/bag, two layers kraft bag with water proof, and with ton bag outside or each ton packed on a fumigation pallet according to customers' request.
