Abstract
Drag out of lead with elongated steel elements (1) upon exit from a bath (2) of molten lead is prevented by bringing the elongated steel elements into contact with an amount of a substance such as H.sub.2 S, Hcl or ZnCl.sub.2 /.nNH.sub.4 Cl, that is capable of transforming lead oxide into another product at the exit conditions of said elongated steel elements (1) from the bath (2) of molten lead. The steel may emerge from the bath into a non-oxidizing atmosphere, such as a bed of coal, where the converted lead or lead compound may be mechanically stripped from the element.
