Description:
Burnt magnesia-chrome bricks are made from high quality magnesia and chrome concentrate, cr2o3 content can be adjusted according to different requirements. The bricks have good thermal stability and high temperature performance, and are widely used in cement kilns and non-ferrous metal metallurgical furnaces and so on. High temperature burnt directly bonded magnesia-chrome bricks, semi-re bonded magnesia-chrome bricks and magnesia-chrome bricks are made from low impurity raw materials. All or part of raw materials are pre-burnt or electro fused. The best proportioning, high pressure molding, ultra high temperature and good volume stability. The bricks are widely used in large cement rotary kiln, and secondary refining units such as RH, VOD, AOD furnaces, non-ferrous metal metallurgical furnaces, glass tanks and so on.
