四辊中板可逆轧机受力频繁。分析轧机两侧机架轧制力、机架拐角应力和液压系统缸内压力之间的关系,对保证设备安全,改进生产工艺有重要意义。实测数据的分析表明,三者之间有很好的线性相关性和性态的一致性,均可作为度量轧机受力状态的参数,特别是用拉式应变传感器测量机架两侧轧制力简单方便,测量数据准确可靠,重复性好。
Reversible four-roll plate mill in force. The analysis of the relationship between the rolling force of the frame on both sides of the rolling mill, the corner stress of the frame and the pressure in the cylinder of the hydraulic system is of great significance for ensuring the safety of the equipment and improving the production technology. The analysis of the measured data shows that there is a good linear correlation between the three and the consistency of the state, can be used as a measure of the rolling mill stress state parameters, especially with the pull strain sensor measuring the rolling force on both sides of the rack Simple and convenient, accurate and reliable measurement data, good reproducibility.
