PURPOSE:To obtain plates and shapes causing no blister at the plated surface in the following plating stage by subjecting cold rolled stocks after annealing- pickling to mechanical polishing and dry rolling. CONSTITUTION:An ingot is hot-rolled and cold-rolled to form a plate or shape, which is subjected to mechanical polishing by wet buff rotary polishing rolls etc., after annealing-pickling, the final stage of the cold rolling, to remove the pickling compounds formed by the pickling from the stock surface completely. Subsequently, the stock is dry-rolled to press the metal powder, which is yielded by the mechanical polishing and is adhering to the stock surface, to the surface so that they are united into one body, which is subjected to oil rolling, if necessary, and then to ordinary degreasing and etching treatments, followed by plating treatment. In this way, the blister-free metal-plated plate and shape can be obtained at a low cost. |
