High Alumina Refractory Brick
Description:
CH Refractories high temperature kiln refractory high alumina bricks use special grade aluminum bauxite clinker as the main raw material, supplemented by special additives, high pressure forming and high temperature firing. Refractory bricks alumina has the characteristics of large heat storage capacity and small creep rate.
Can provide Al2O3 content from 45%~85% high alumina refractory brick, SK35,SK36,SK37,SK38,SK40 high alumina fire brick.
The high alumina brick made by CH refractories with very widely application and various size with free mold charge to meet different kiln applications. To be professional high alumina furnace brick manufacturer since 1984, CH refractories provides alumina lining bricks not only can design fire furnace bricks size according to your kiln or furnace drawing for free, but also suggest you the most economical refractory furnace alumina bricks price for your kiln or furnace. Generally , there are three levels lime kiln refractory high alumina brick in our plant, just please inform bricks working condition, CH refractories will suggest you the most suitable alumina refractory bricks to save your money and achieve the best performance.
