Method and apparatus for producing hot-dip coated metal belt

摘要

The invention provides a method for producing a hot-dip plated metal strip comprising the steps of: annealing a metal strip; imparting plastic strain to the metal strip; drawing the metal strip into a molten metal bath for plating; drawing up the metal strip out of the molten metal bath without contacting the molten metal with a roll in the molten metal bath after turning around the metal strip upward with adhering the molten metal on the metal strip; and controlling the coating weight of the molten metal adhered on the metal strip-with a wiper. According to the method of the invention, a hot-dip plated metal strip can be produced, in which buckling does not occur, lateral evenness of coating weight is excellent, and dross defects are few.
