Magnesia Chrome Brick

Direct Bonded Magnesia Chrome Brick

Direct Bonded Magnesia Chrome Brick is made from high purity magnesia and chromite materials and sintered under the high temperature in the tunnel kiln, it’s widely used in the lining of the RH/DH vessel , cement rotary kiln, glass tank furnace, non-ferrous metal metallurgical furnace, AOD, VOD furnaces, etc.

Re-Bonded Magnesia Chrome Brick

Re-Bonded Magnesia Chrome Brick is made from fully electro-fused MgO-Cr2O3 grain, and fired under more than 1700 ° C with weak oxidizing atmosphere. It’s a high quality Magnesia Chrome product with excellent strength & volume stability at high temperature, excellent slag corrosion resistance and erosion resistance; widely used in second-refining furnance, like slag line of VOD and AOD, RH/DH’s snorkels and regenerators of glass kiln ,etc.

Semi-Re-Bonded Magnesia Chrome Brick

Semi-Re-Bonded Magnesia Chrome Brick is made from electro fused MgO-Cr2O3 grain, fused magnesia, chromite and some sintered MgO-Cr2O3 grain, then fired at high temperature. It has some characteristics both direct bonded and re-bonded, like dense inner structure, lower porosity, good high temperature strength, thermal shock resistance is better than re-bonded, slag erosion resistance better than direct bonded. It can be used in sidewall of EAF, DH/RH degasser, VOD, LF, AOD’s side wall/bottom or free board and some serious parts like slag line, regenerators of glass furnace, etc.
