摘要：The invention relates to a descaling system for descaling in hot rolling mills,comprising at least one hydraulic pump (P1) which is driven by means of a pump motor(M). Here, the pump motor (M) is configured as a pole-changing motor and is connectedto a controller (STR) which is set up for pole changing between descaling times anddescaling pauses. A considerable amount of energy is saved in this way during a descalingpause, by the rotational speed of the pump motor (M) being reduced by means of polechanging.
