The brick was made from high grade bauxite, the bricks are processed by moulding under high pressure and sintering under high temperature, with features like large heat accumulating capacity and small creep rate. They are available for blast hot stove matched of middle and small blast furnace.
1-Cheaper price compared with other refractory bricks
2-Most widely application
3-Size can be made according to requirements
1-Different high temperature kiln, such as cement kiln
2-Used as insulating layer
