双机架平整机组摩擦因数模型的开发

双机架平整机组湿平整轧制过程中影响摩擦因数的因素较多,采用常规方法无法回归问题。在大量的现场试验与理论研究的基础上,通过对辊缝中润滑油膜厚度与摩擦因数之间关系的定量研究,建立了一套双机架平整机组湿平整轧制过程中的摩擦因数模型,解出了双机架平整机组机架间的延伸率分配系数,并将其应用到某1420连退平整机组的生产实践,取得了良好的使用效果,具有进一步推广应用的价值。

Development of Friction Coefficient Model of Double Stands Temper Mill

As there were more factors affecting the friction coefficient in the process of the wet skin pass rolling of double stands temper mill,the regression could not be done when used the conventional methods.After a number of field experiments and theoretical studies,a friction coefficient model had been built in the process of the wet skin pass rolling through the quantitative research on the relationship between the lubricating film thickness in the roll gap and the friction coefficient.And the elongation dist...
