Owen Pearcey (Hatch Ltd)23/06/2021, 16:10HDG Process Technology - Furnace, Galvanizing Bath, Coating Weight ControlOral PresentationHatch has been developing and deploying a model-based coating control system for over 20 years. The resultant physics-based gas wiping process model has been adapted to a wide variety of equipment and coatings now being produced by the major steel producers. As the coating control technology has matured and the processing ability of PLCs has increased, the process model and control system has...Go to contribution page

MICHEL DUBOIS (CMI INDUSTRY)23/06/2021, 16:30HDG Process Technology - Furnace, Galvanizing Bath, Coating Weight ControlOral PresentationThe paper adress the problem of crossbow correction with a 3 pot roll system. in order to estimate the curvature radius of the strip wrapping the rolls, an elastic assumption is taken. It comes that a single position of the stabilizer or Sink rol cannot correct all the prodcuts, especially the thicker onesGo to contribution page

Takashi OKE (NIPPON STEEL)23/06/2021, 16:50HDG Process Technology - Furnace, Galvanizing Bath, Coating Weight ControlOral PresentationGas wiping is one of the most important processes which determine the product quality in continuous galvanizing line. Here, there are many problems known as, stability of coating weight, edge splashing and full splashing. We focused on the full splashing phenomenon which the runback flow of zinc detaches the substrate and pours on the gas nozzle. Generally, this phenomenon is known to occur...Go to contribution page

Jaap van Eenennaam (Tata Steel in Europe)23/06/2021, 17:10HDG Process Technology - Furnace, Galvanizing Bath, Coating Weight ControlOral PresentationIncreasing revenues in Hot Dip Galvanising can be achieved by increasing the line productivity. Therefore, the industry trend is to increase line speed. However, in elevating line speed of a hot dip galvanising line the drag out of molten zinc on the strip increases. As a consequence, more molten metal has to be wiped from the strip. To accomplish this air knives are of increasing importance....Go to contribution page
