异步轧制是近两年来引起人们注意的一项轧制新工艺.从1973年以来的实验和生产使用情况来看,求用基于“HB”法轧制思想的“S”异步轧制法对薄带钢的平整生产来说是有成效的.本文阐述了该法的工艺条件和特点;提出关于张力、压力等参数的近似表达式,用轧制的弹塑性变形曲线图和静摩擦力作用原理.分析了该法能稳定轧制的原因;并将实验和生产中的应用情况和结果作了简要介绍,认为平整能力、操作要求、产品质量等方面都比普通平整法优越和具有特点.
Asynchronous rolling is a new rolling technology that has drawn people’s attention in recent two years.From the experimental and production use since 1973, it is necessary to use “S” asynchronization based on “HB” rolling theory The rolling method is effective for the flat production of thin strip steel.This paper describes the process conditions and characteristics of the method, puts forward an approximate expression about tension, pressure and other parameters, using the elastoplastic deformation curve of rolling The principle of static friction is analyzed. The reasons for the stable rolling of the method are analyzed. The application and the results in the experiment and production are briefly introduced. It is considered that the method is superior to the ordinary smoothing method in terms of formation ability, operation requirement and product quality It has the characteristics of.
