<p>In the electrolytic coating of one side of a moving metal strip (1), the strip as cathode is in contact with a rotating roller (3) and an insoluble anode (4) is concentric with the roller (3) at a distance from the strip (1) so that a slot (5) is formed. The electrolyte flows through the slot (5) at a sufficient average velocity that turbulent flow occurs, and is fed from a nozzle (9) as a fluid jet into the slot (5) opposite to the direction of travel of the strip (1) at the end of the slot (5) at which the strip (1) exits. To improve efficiency, the conformation of the nozzle (9) is substantially uniform across the whole width of the strip and the electrolyte is fed into the slot at a velocity that nowhere varies more than 10% from the said average velocity of the electrolyte.</p> |
