| 摘 要： | 液压剪是连铸生产线上使用的关键设备,具有体积小、工效高、无金属损耗等优点。文中对300t液压剪的液压系统进行了设计计算。采用二通插装阀结合普通滑阀的复合控制方式,同时采用了多台变量泵供油的流量适应回路,增设了蓄能器和独立的冷却过滤回路。液压剪实际使用效果良好,系统效率高,压力冲击小,工作频率高,控制方便。 |

| Abstract: | The hydraulic shearing machine is one of the key equipments in the continuous-casting line.It has the advantages of small size,high efficiency,less loss of metal,etc.A shearing machine hydraulic system is studied.It is controlled by adopting compound control pattern formed by cartridge valves and common slide valves.Meanwhile,it utilizes four variable pumps to supply oil to the flow adaptation circuit.In addition,it adds accumulators and independent filter cooling circuit.Results show the hydraulic shearing machine has advantages of higher system efficiency,lower hydraulic shock,high working frequency,easy to control etc. |
| Keywords: | hydraulic shearing machine cartridge valve hydraulic system heat checking |
