Product introduction of magnesia aluminum spinel brick
The magnesia-aluminum spinel brick is manufactured from good synthetic spinel raw material and special process. The product has the characteristics of high compressive strength, good thermal shock stability, good thermal creep energy and high load softening temperature. At the same time, the magnesium-chromium bricks are easy to stick to the kiln skin, which solves the problem of the production of hexavalent chromium-potassium by the magnesium-chromium bricks used in the cement kiln and pollutes the environment.
