马钢初轧厂6 VH钢坯连轧机组是第一重型机器厂仿宝钢初轧厂连轧设计制造的,具有较高的技术水平。机组采用了多个液压系统,以完成钢坯的翻转夹送、轧辊与接轴的平衡、机架紧固、定位,换辊等多种动作,并在这套国内首次制造的大型连轧机上采用了水一乙二醇作为工作介质。连轧机轧制方坯时,由初轧机来的方坯由45°翻钢机夹持,翻转45°,喂送进6VH轧机,全部动作均由液压系统完成。为满足生产需要,各液压缸和液压马达分别由φ32mm电液换向阀控制,流量较大。管路中配有φ32和φ25高压胶管24根。翻钢机每喂一根钢,胶管都要依次充压,扭曲各一次,因此寿命较短。由 Masteel rolling plant 6 VH slab continuous rolling mill is the first heavy machinery factory imitation Baosteel rolling mill design and manufacture of rolling, with high technical level. The unit uses a number of hydraulic system to complete the billet flip pinch, roll and shaft balance, rack fastening, positioning, roll change and other movements, and in the first domestic production of large tandem mill A water glycol as a working medium. Even rolling mill billet, the billet from the initial rolling mill by 45 ° turning machine clamping, turning 45 °, feeding 6VH mill, all movements are completed by the hydraulic system. In order to meet the production needs, the hydraulic cylinder and hydraulic motor are respectively controlled by φ32mm electro-hydraulic directional control valve, and the flow rate is relatively large. The pipeline is equipped with φ32 and φ25 high-pressure hose 24. Every time a steel machine is fed, the hose should be pressurized and twisted one by one, so the service life is shorter. by
