      Refractories for copper smelting furnace and RH furnace

         The main furnace type of copper smelting furnace and RH furnace is mainly used for the construction of high grade magnesium-chrome brick and pouring material, because the furnace type is different and the life span is different. The physical and chemical indexes of refractory materials produced by China magnesium group are as follows.
