UTILIZATION OF INDUCTION HEATING TECHNOLOGY IN GALVANIZING LINES
Abstract
Continuous Hot-Dip Galvanizing lines are widely used for the production of coated steel sheets. Quality improvement measures are of great importance for this type of line. A significant proportion of production and quality losses when operating these types of lines occurs when production is transitioning from one strip gauge/thermal cycle to another. Utilizing induction heating technology, in combination with a sophisticated control system, can dramically decrease yield losses during transitions. Dynamic Transition and Production Planning Models have recently been developed for the simulation and control of the continuous hot-dip galvanizing line. The results of this work have been implemented in some galvanizing lines with production rate up to 350,000-ton annual capacity.
