magnesia-calcium brick
產品參數
Magnesium calcium brick is made from magnesia and magnesium calcium sand as main raw materials. According to different needs, the appropriate proportion of magnesium and calcium is made by anhydrous binder, which is formed by high pressure and fired at high temperature. It has good high temperature resistance, good thermal stability, strong chemical impregnation resistance, and is conducive to the purification of steel such as desulfurization and dephosphorization. It is mainly used in key parts of stainless steel refining furnace, AOD furnace, VOD furnace, ladle and so on.
