1,Description of Magnesia Calcium Brick:
At present, there are two kinds of magnesia-calcium bricks, CaO20% and CaO 30%. They are used in AOD furnace and VOD furnace for smelting stainless steel, replacing the original magnesia-chromium brick,major raw materials for producing magnesia-calcium bricks are light-fired synthetic magnesia-calcium sand, fused magnesia, which are formed by hydraulic press and fired at 1550℃-1600℃ degrees Celsius.The finished product is impregnated with paraffin to cover the surface with a layer of paraffin film to avoid hydration reaction during storage, transportation and masonry.
