The invention relates to the technical field of steel-making molten iron pretreatment mechanical equipment, in particular to a lifting hook lifting type molten iron tank tipping hydraulic control system and method. Through cooperation of the tipping work control oil way, the tipping accident reset oil way and the pressure control oil way, accurate and efficient control over tipping operation of the lifting hook lifting type molten iron tank can be achieved, reliability is high, and safety is high; the hot-metal bottle is tipped in a manner of lifting a lifting hook by a single hydraulic cylinder, so that the problem of synchronization of jacking and tipping of double hydraulic cylinders is avoided, the tipping reliability is higher, and the maintenance is simpler; by adjusting input signals of the proportional reversing valve, the running speed of tipping and resetting of the hot-metal ladle is controlled, a low-speed running mode is adopted when the hot-metal ladle starts tipping and stops tipping, a high-speed running mode is adopted in the middle tipping stroke of the hot-metal ladle, the process requirements can be well met, and the working efficiency is improved.
本发明涉及炼钢铁水预处理机械设备技术领域,具体涉及一种吊钩提升式铁水罐倾翻液压控制系统及控制方法。通过倾翻工作控制油路、倾翻事故复位油路和压力控制油路相配合,能够实现吊钩提升式铁水罐倾翻运行的精确、高效控制,且可靠性强、安全性高;铁水罐倾翻采用单液压缸提升吊钩的倾翻方式,避免了双液压缸顶升倾翻的同步问题,倾翻可靠性更强,且维护更加简单;通过调节比例换向阀的输入信号,从而控制铁水罐倾翻和复位的运行速度,且在铁水罐开始倾翻和停止倾翻时采用慢速运行模式,在铁水罐倾翻中间行程中采用快速运行模式,能较好满足工艺需求,提高工作效率。
