Abstract

The weight and distribution of the coating material applied to a moving steel strip, extracted from a bath of molten zinc, are advantageously controlled by combined action of magnetic forces that are induced in a layer of coating by means of a non- continuous magnetic field and a jet of gas. The synergistic effect of the electromagnetic forces and the jet of gas enables removal of the coating material in excess, prevention of a premature solidification of the coating layer in the area of impact of the gas, and prevention at the same time of any oscillation of the strip. Thanks to the jointed action of the magnetic forces and of the gas jets a uniform coating is obtained.
