WebProduct Details. Magnesia Chrome Brick is characterized by a high direct bonding rate and large crystals. It has good resistance to heat flaking. Low alkali neutrality has good slag resistance when repairing low acid feed furnaces. The main raw materials for manufacturing magnesia-chrome bricks are sintered magnesium and chromite. WebTo prevent dolomite brick hydration, wax immersion and water free packing are usually used. Wax immersion is: immerse the 60~100℃ dolomite brick into liquid paraffin and cools in the air. The liquid paraffin permeates into brick pores and form a thin film about 10 μm after solidification.
