  • Method for controlling a coating weight uniformity in industrial galvanizing lines
    Patent number: 11685984
    Abstract: A method for controlling and optimizing a transverse uniformity of a coating thickness on at least one side of a running metal strip in an industrial galvanization installation, the coating being deposited by hot dip coating in a pot containing a liquid metal bath, includes at least the steps of: heating the strip substrate to a temperature higher than a pot temperature; passing the strip through the bath by wrapping the strip around at least a first deflector roll or sink roll followed by at least one second deflector roll, the second deflector roll improving a flatness of the strip; wiping excess coating thickness carried away by the strip on one or both sides of the strip by wiping nozzles blowing a gas on the strip at an exit of the liquid metal bath; and measuring an actual distance profile between the nozzles and the strip.
