In addition to the main motor of the rolling mill on the hot rolling production line,the largest installed capacity is the descaling pump motor,which has a large space in reducing production costs.The key equipment of the hot rolling descaling system is introduced,the characteristics of various empty rolling times are summarized,and the different stages of the work-ing state of the descaling pump are analyzed.The energy-saving method is studied based on the configuration of the existing descaling system,and the practical debugging application is carried out.According to the characteristics of the finishing roll-ing descaling system and the roughing rolling descaling system,different energy-saving schemes are given,and it is clarified that the energy-saving section of the descaling system is mainly used in the roughing rolling area.The configuration of the large-volume accumulator group plus frequency conversion speed regulation system is the best energy-saving scheme for the roughing rolling descaling system,which provides an energy-saving reference for the design and transformation of the desca-ling system.
