MOLD WIN METHOD FOR PLATING ORIGINAL COPPER PLATE MOLD FOR CONTINUOUS CASTING

摘要

PURPOSE: A Mold Win method for plating copper plate mold is provided, which has good resistance to heat and abrasion and high hardness for continuous casting operation. CONSTITUTION: The method is provided to plate the copper plate with nickel and nickel -boron alloy in layers of one over the other. The process of forming the layer of nickel-boron alloy follows the steps of electrolytic cleaning and water cleaning of the nickel surface for pretreatment and placing the mold in an electrolyte including sulfuric acid, boric acid nickel sulfate to make the nickel electrode for an anode and form nickel plating nucleus on the nickel layer surface to plate a layer of nickel-boron alloy on it.
