W12 4-rolling machine

    
    W12 4-roll rolling machine with mechanically-driven up-roll, and hydraulically-driven low-roll and side-roll, is electrically controlled. The machine can finish pre-changing of two ends of plates, rolling of cylindrical or arc parts, levelling and pre-bending of metal plates at one time,thus, it is very effective.
