Mathematical Model for Strip Surface Roughness of Stainless Steel in Cold Rolling Process
Surface roughness control is one of the most important subjects during producing stainless steel strips.In this paper,under the conditions of introducing to the concepts of transferring ratio and genetic factor and through the further theoretical analysis,a set of theoretical models about strip surface roughness were put forward in stainless steel cold tandem rolling.Meanwhile,the lubrication experiment in cold rolling process of SUS430 stainless steel strip was carried out in order to comprehensively study surface roughness.The effect of main factors on transferring ratio and genetic factor was analyzed quantitatively,such as reduction,initial thickness,deformation resistance,emulsion technological parameters and so on.Attenuation function equations used for describing roll surface roughness were set up,and also strip surface roughness at the entry of last mill was solved approximately.Ultimately,mathematical model on strip surface roughness for cold tandem rolling of stainless steel was built,and then it was used into the practical production.A great number of statistical results show that experimental data is in excellent agreement with the given regression equations,and exactly,the relative deviation on roughness between calculated and measured is less than 6.34%.
