Product introduction of magnesia hercynite brick
The magnesia hercynite brick is made of good synthetic spinel raw materials and special processes. It also has the characteristics of being easy to stick the magnesia chrome brick directly to the kiln skin, which solves the problem of environmental pollution caused by the production of potassium hexachrome in the use of magnesia chrome bricks for cement kilns.
Feature of magnesia hercynite brick
The magnesia hercynite brick has the characteristics of high compressive strength, good thermal shock stability, good thermal creep property and high load softening temperature.
Advantages of magnesia hercynite brick
Magnesite hercynite bricks are mainly used in the firing zone of large dry process cement rotary kilns.
