Method for operating a brush system on a rolling stand and brushing system

摘要

Method for operating a brush installation (1) on a roll stand (2), wherein the brush installation (1) comprises at least one rotating brush (3) which can be brought into engagement with a work roll (4) of the roll stand (2), wherein the brush (3) is rotationally driven by a hydraulic motor (5), the hydraulic motor (5) being connectable to a pressurized fluid supply source (6), the pressurized fluid supply source (6) comprising a pump (7) and a drive motor (7) driving the pump (7). 8) and wherein a working fluid is maintained at a predetermined base pressure (p0) by the pump (7), characterized in that the method comprises the steps of: a) detecting the force applied to the work roll (4) by the brush (3) Load and / or the power consumed by the brush (3) (PB); b) determining a working pressure (p1) of the working fluid required for application of the load or application of the power (PB) of the brush (3); c) comparing the required working pressure (p1) with the base pressure (p0); d) Reduction of the drive power (PM) of the drive motor (8) of the pressure fluid supply source (6), when the working pressure (p1), taking into account a tolerance, is lower than the base pressure (p0) and increase the drive power (PM) of the drive motor (8) the pressurized fluid supply source (6) when the working pressure (p1), considering a tolerance, is higher than the base pressure (p0).
