济钢宽厚板厂5000 t压力矫直机的应用

摘要

Pointing to some problems such as low rigidity of the frame, back spring of steel plate after straightening, lacking straightening force caused by oil leakage of main hydraulic cylinder in the use process of pressure straightening machine, through taking a series of measures such as calculating prestrss for insuring the rigidity of the frame, anti-uneven-loading design of main hydraulic cylinder and hierarchical control of the pressure and speed of hydraulic system, the oil leakage was solved, ensuring straightening effect.%　　针对压力矫直机使用过程中出现的机架刚性低、钢板矫直后回弹、主液压缸漏油不能保压造成矫直力不足等问题，通过计算预应力确保机架刚性，采取主液压缸防偏载设计、液压系统压力和速度分级控制等措施，解决了漏油问题，确保了矫直效果。
