Abstract

A hot dip coating system comprises a bath of molten coating metal contained in a vessel having a strip passage opening located below the top surface of the bath. A metal strip is directed along a path extending through the strip passage opening and through the bath of molten coating metal, to coat the strip. An electromagnet is employed to prevent the escape of the bulk of the molten coating metal from the bath through the strip passage opening while permitting the strip to move along its path.
Expedients are provided to reduce leakage of molten coating metal through the strip passage opening.
