Low Carbon Brick and Carbon-free Brick

Honsin series of magnesia-chrome bricks are composite basic refractory products, made by magnesite and chromite which are burned at high temperature or ultra-high temperature. The products show the features of excellent resistance against slag, high fired strength, good erosion resistance and thermal shock resistance. They can be applied in AOD/VOD refining furnace, DH/RH degassing device, and lining of nonferrous metal converter.
