presser roller

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.

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。

HC轧机辊间压力分布的分析

So during calculating the distribution of pressure between rolls,the model with offset can be instead.

计算结果表明,其与不带有偏移量的辊间压力分布基本相同。
