Modernization of a Tandem Cold Rolling Mill at Arcelor …

Each stand of the 4-Stand Tandem Mill is driven by two respective four DC motors. The DC drives are supplied via two motor-generator sets, each consisting of a 19.5 MW synchronous motor and four genera-tors. Each generator supplies the armature circuits of two or three main motors. The load is balanced via the field supply.
