Industrial Benefits of Siemens Wiping System Implementation on Continuous Galvanizing Lines
Installed in Bor?elik,the Dynamic Air Knives system (DAK?E) which allows the best characteristics of coating products,permits managing,automatically and on-line,the opening of the lips across the width of the strip.This leads to reach an accurate controlled width homogeneity of the zinc coating thickness.Main objectives of DAK?E are to save zinc within coating thickness target with lip gap adjustment,to improve surface quality with air cushion and to improve strip weldability with a more consistent distribution on zinc coating.DAK?E equipment is able to control on-line lip profile,air pressure and distance strip/nozzle according to operation and process condition variation: strip shifting,strip cross-bow and strip section changes.In addition and to improve coating surface quality,DAK?E system is supplied with an automatic lip cleaning,a contactless baffle including an autocentering device.Bor?elik and Siemens teams worked together to optimize the performances of this wiping equipment.DAK?E finally shows an excellent behaviour with about 2% decrease on zinc deposited thickness target which can lead to interesting and significant zinc savings,in the frame of the requested coating thickness tolerances target.In conclusion,such system DAK?E installed in Bor?elik CGL 3 allows to get better performances and to have a rapid return of investment.
