Bessemer surface repair material
Product parameter
Production process: high purity magnesia and high purity synthetic dolomite sand as the main raw materials, at the same time adding wetting agent and sintering agent by hot mixing.
Main application: hot repair of converter surface.
Usage method: When repairing a large area, pour -200-300kg (according to the size of the converter and the degree of erosion and area of the lining brick) of the large surface hot repair material into the furnace with a chute to repair the part, sintering 10-30 minutes (according to the thickness of the repair material) can be used; For small area local repair, our company produces 10kg/ bag and 5kg/ bag of hand-cast hot repair materials according to the use habits of steel mills, which can be selected according to the specific situation of the repair parts.
