For the improvement of the productivity and work safety, the company Unitechnik Automatisierungs GmbH has developed a procedure for the automatic skimming of slag at the zinc coating line. With this procedure, slag is continuously skimmed from the zinc bath's surface and temporarily stored in a special tank. Depending on the filling level, the tank is emptied and the slag recycled. Specifically for this, Unitechnik has constructed a skimming tool and the corresponding movement strategies to gently skim the zinc dross. The control of such installations can be integrated in the existing installation control, or be realized independently with the corresponding interfaces.
