Abstract
A method and apparatus for galvanizing an elongated conductive metal element by drawing it through a bath of molten zinc in a conductive pan. Corrosion of the pan is prevented by electrically isolating the element from the pan, except through the zinc, eliminating circulating currents between the element and the pan wall. Quality of the coating, and particularly the uniformity of the thickness of the zinc deposited on the element, is improved by stabilizing the electrical potential in the element and thus the current flowing longitudinally through it. Where multiple elements are drawn in parallel through the bath for simultaneous galvanizing, circulating currents between them are minimized by electrically short circuiting the elements at the incoming and exit ends of the bath.
