In the precision cold rolling of aluminium strips, heating up the side areas of the work roll barrels is critical to prevent the “tight edge” phenomenon—a localized increase in strip edge thickness and hardness caused by excessive heat loss at the roll ends. This defect leads to poor flatness, edge cracking, and significant yield loss in high-value products.
Metals-Tech’s Electromagnetic Work Roll Heating System with our partners provides an advanced, targeted solution to this persistent challenge. Unlike hot edge spray method, our system utilizes precisely controlled electromagnetic induction to apply direct, localized heat to the work roll barrels, with a focus on maintaining optimal thermal crown—especially at the critical roll edges.By integrating this innovative system, aluminium producers can dramatically reduce edge-related scrap, expand the operational window for challenging alloys and gauges, and achieve a new level of thickness consistency and strip shape—directly translating to higher yield, reduced finishing costs, and entry into more demanding market segments.
