摘要

A hot dip zincing method comprising the steps of dividing a plating vessel storing molten metal therein into a plating tank and dross removing tank, dipping a steel strip into molten metal bath in the plating vessel for hot dip zincing, transferring the molten metal bath in the plating vessel to the dross removing tank, removing in the dross removing tank dross in the molten metal bath, and returning the molten tank in the dross removing tank to the plating tank via an opening provided in the plating tank. The plating device comprising a plating tank, a dross removing tank, means for transferring the molten metal bath in the plating tank to the dross removing tank and the opening provided in the plating tank for returning the molten metal bath in the dross removing tank to the plating tank.
