Firebrick, High Alumina Brick, Refractory Castable, Firebrick(High alumina bricks,Phosphate brick,Magnesite Alumina bricks,fire clay brick,refractory brick,ceramic brick) is made from high purity refractory clays and other raw materials, with light weight and mini-porosity well distributed. Each brick is machined to precise tolerances on all six faces.
Characteristic:
- Low thermal conductivity
- Low heat storage
- High spalling resistance
- High hot compressive strength
- Low iron oxide and alkali flux content
- Accurate dimensions.
Application: - Hot face refractory lining for furnaces, kilns, flues, refining vessels and heaters, regenerators, gas producers and similar high temperature industrial equipment.
- Back up insulation for furnaces, kilns and similar high temperature industrial equipment.
Specification: - Classification Temperature: 1260C, 1425C, 1538C, 1650C, 1790C.
