Abstract
Metal, e.g. copper, is electrolytically deposited within the recess formed over a plugged hole of a component of a pyrometallurgical vessel, e.g. a cooling block, to form a seamless seal with the surface of the component. The method comprises the steps of inserting a mechanical plug into a channel opening of the component such that a recess is formed between the external surface of the plug and the outer surface of the component; positioning an anode adjacent the recess; providing an aqueous solution containing metallic ions, e.g. a solution of copper sulfate, between the anode and the mechanical plug; and creating an electric potential across the anode and the mechanical plug such that metal is deposited within the recess, preferably until the recess is filled with the electrodeposited metal. In alternative embodiments, the process can be used to secure fittings and the like to the components or to repair ruptured or weakened areas along the perimeter of such fittings.
