带钢平直度的精度取决于几个因素;轧辊磨损是影响带钢表面质量的主要变量之一。轧辊磨损源于复杂的摩擦条件,因为带钢不与支承辊接触,有时没有分析支承辊磨损;但几个轧制周期之后,因为压力分配不均匀,支承辊磨损就变得很危险了。研究带钢热轧机支承辊表面劣化对开发带钢热轧机板形自动控制系统而言是非常重要的。根据两个轴线平行的圆柱体之间的Hertz压力分布开发了一个数学模型。实时使用该模型来计算支承辊磨损,并据此来防止支承辊过度磨损造成成品返工或损坏设备的事故。 The accuracy of strip flatness depends on several factors; roll wear is one of the main variables that affect strip surface quality. Roller wear originates from complex frictional conditions because the strip does not come into contact with the backup roll and the backup roll wear is sometimes not analyzed; however, after several rolling cycles wear on the backup roll becomes dangerous due to uneven pressure distribution. It is very important to study the surface degradation of back-up roll of strip hot-rolling mill in the development of strip-shaped automatic control system for hot strip mill. A mathematical model was developed based on the Hertz pressure distribution between two cylinders parallel to each axis. The model is used in real-time to calculate backup roll wear and, accordingly, to prevent over-wear of the backup roll resulting in finished product rework or equipment damage.
