PATCH 74 top sealing Dry ramming mass material Refractory for ferrous alloy for Vacuum induction furnace work lining

PATCH 74 is fused corundum wet vibrating furnace sealing refractory material for coreless induction furnaces for melting steel and other high temperature metals. The materials are packaged in dry form, add water and stir on site according to the instructions to obtain the designed density and strength. PATCH 74 uses magnesium oxide and corundum as the main raw materials to form magnesium aluminum based spinel material after sintered, which can improve the thermal shock resistance and erosion resistance of the material, reduces or avoids cracks in the furnace collar and working furnace lining, and resists mechanical collision and wear .
