It's a huge challenge to avoid excessive tension at the strip edge during aluminum strip cold rolling. The conventional solution is the hot edge spray (HES) method of heating the work roll barrel. New on the market, our inductive edge heating system reduces strip tension. That ensures faster rolling speeds at lower energy consumption and higher efficiency.

Essentially, the principle behind our inductive edge heating system is an alternating magnetic field that induces eddy currents to generate heat directly on the roll surface.
