The invention discloses a novel finish rolling hydraulic system for a steel rolling workshop. The system comprises an oil tank and a plurality of hydraulic pump sets connected in parallel, and the hydraulic pump sets comprise at least two conventional pump sets and a standby pump set; and each hydraulic pump set is connected with the oil tank through an independent pump set oil conveying pipe, and an outlet of each pump set is connected to an oil conveying header pipe for providing hydraulic pressure for a rolling mill set. A pump set oil return pipe is connected to the position, behind the hydraulic pump sets, of the oil conveying header pipe; an oil return header pipe and an overflow pipe are connected between a rolling mill set and the oil tank; and the system further comprises a cooling system and an energy storage system. The plurality of hydraulic pump sets connected in parallel are arranged in the system, one part serves as the conventional pump sets, the other part is the standby pump set, and the two parts alternately work and complement each other.
Description
technical field [0001] The invention relates to a finishing rolling hydraulic system suitable for a steel rolling workshop. Background technique [0002] The process of pressing the steel ingot to change the shape of the billet between the rotating rolls is called steel rolling. The purpose of steel rolling is the same as other pressure processing. On the one hand, it is to obtain the required shape, such as: steel plate, strip steel, wire rod and various types of steel, etc.; on the other hand, it is to improve the internal quality of steel. In the existing steel rolling workshop, the hydraulic system in the rolling area shares one hydraulic device for rough, medium and finish rolling. When multiple actuators are used, the pressure and flow often cannot meet the production needs. Contents of the invention [0003] In view of this, the present invention provides a new hydraulic system for finishing rolling in a steel rolling workshop, which meets the needs of the rolling ...
