Accurate calculation of strip steel elongation in tension leveling process
摘要
Abstract
In the tension leveling process, the traditional method to calculate of the strip elongation only considers the extension rate after the tension recovery, but ignores the extension loss after bending elastic recovery of the strip steel, so the calculated value of elongation is large enough to affect the process control accuracy. This paper considers not only the residual strain after bending elastic recovery, but also the influence of the residual deformation on the neutral layer extension under plain cross-section assumption. The comparative analysis of mass test results show that the extension rate calculation result obtained from the new formula is much closer to the simulation result, compared with the traditional calculation method. It indicates that, as for the tension leveling process, the parameters set by the new method is more accurate than those set by the traditional method.关键词
