轧机张力计测量系统精度分析

Accuracy analysis of rolling mill tension gauge measurement system

首钢迁钢酸连轧机组是非常重要的产线,酸连轧机组的张力计表对于机组的的张力控制起着非常重要的作用,是酸连轧机组连续生产的保证。因此,张力计的稳定性和测量精度直接影响酸连轧机组的生产。影响张力计测量精度的因素主要包括张力辊包角、压头绝缘下降、压头信号电缆信号干扰和张力计控制单元电子元件老化等。通过定期检查张力辊包角、检测压头绝缘、电缆接地等措施保证张力计检测系统稳定准确地运行,减少张力计检测系统故障,保证轧机连续稳定运行。

Shougang Qiangang acid continuous rolling unit is a very important production line.The tension meter of the acid continuous rolling unit plays a very important role in the tension control of the unit.It is a guarantee for the continuous production of acid continuous rolling unit.Therefore,the stability and measurement accuracy of the tension meter directly affect the production of acid continuous rolling unit.The factors affcted the measurement accuracy of tension meter include the angle of tension roll,the decrease of insulation of pressure head,the signal interference of pressure head signal cable,and the aging of electronic components of tension meter control unit.Through the regular inspection of the tension roll wrap angle,the test head insulation,cable grounding and other measures,the stability and accuracy of the tension meter detection system are ensured.The tension meter detection system failure is reduced,and the stable and continccous operation of rolling mill is ensured.
