Product Description
The high quality MgO-CaO clinker is used as raw material for the production of the product. According to the customer' requirement to select the ratio of MgO/CaO, the bricks are manufactured by the process of rational proportioning, high pressure moulding, high temperature burning, vacuum pich or pyrophyllite impregnation under pressure. The product is characterized by good slag resistance, high strength under high temperatures, good thermal shock resistance and so forth. The bricks are mainly used in the equipment of VOD, AOD and ladle furnace etc, for secondary steelmaking.
