ABSTRACT OF THE DISCLOSURE A molten metal plating method and apparatus is provided. In such apparatus a horizontal molten metal plating tank is arranged in a horizontal strip pass line. A current and a magnetic field, which intersect each other at right angles, is provided at the strip feeding and the discharge ends of such tank. The current and magnetic fields are applied in a direction perpendicular to the direction of travel of a steel strip to apply an electromagnetic force to the molten metal at each end thereof, such force being directed toward the inside of the plating tank. By adjusting the intensity of the mag- netic field or the amount of current, the run-out or leakage of the molten metal from the strip feeding and discharging ends of the plating path is reduced to substantially zero or controlled to a desired value. The effect of this is that the molten metal is effectively prevented from leaking out at the strip feeding end of the plating tank, while at the discharging end of the tank the coating thickness or the weight of coating on the plated strip is controlled. A horizontal linear coating line is provided, thus making the plating of heavy-gauge steel strip or plate and the application of thicker coatings possible.
