摘　　要：采用影响函数法建立轧辊的弹性变形解析模型,针对首钢3 500 mm中板轧机在轧制过程中,支承辊端部出现剥落或掉肉现象,根据首钢中板厂的轧制工艺,分析了不同板宽、不同轧辊辊型、不同轧辊端部倒角以及直倒角参数对辊间压力分布的影响规律。研究结果表明,在轧制能力范围内,轧件越宽,轧辊采用凹辊型可以使辊身部的辊间压力分布更为均匀;倒角的选择和改变直倒角的参数都会相应地改变端部的应力集中现象。研究结果为该轧机的辊型的改造和配置以及提高轧辊寿命提供了理论依据。The inactivation and scaling of backup rolls in 3500 mm plate mill at Shougang Group are caused by non-uniform contact pressure distribution as well as stress concentration at the edges of rolls. An analytic model of roll elasticity deformation based on the influence function method was developed to simulate the rolling process. The effects of rolling parameters such as plate width, roll contours, chamfer and straight chamfer parameters on the contact pressure distribution were studied. The results show, that for wide plate and roll with concave contour, the contact pressure distribution tends to be uniform, the stress concentration at the edges of rolls is influenced by chamfer parameters. This analysis can be used as the basis for optimizing design of the roll contour, and enhancing the roll service life.
