Abstract

A process for producing a metal-coated ferrous strip, whereby a basic ferrous metal strip is thoroughly cleaned first, then introduced into and removed from a molten metal bath by carrying a layer of the molten metal, characterized in that the cooling of said molten coating metal is controlled by applying a heating or cooling fluid to selected longitudinal zones of said band.
