Title: Control method by draft setting in rolling mill
Inventor: OGAWA SHIGERU
IPC: B21B37/00
Filed: 1983-07-28
Abstract: PURPOSE:To maintain sheet thickness highly accurately by deciding a draft set- value basing on a mill stretch (an increment of roll gap between upper and lower roll due to a rolling load and a bending force) obtained by theory and experiment. CONSTITUTION:The causes of a mill stretch are separated into roll deformation and other factors. As the deformation characteristics of these factors are complex and difficult to resolve, a press-squeezing experiment is performed by previously touching the upper and lower rolls. From the relationship between a rolling load and a draft set-value obtained from those results, a contributory content other than roll deformation excluding the contributory content of roll deformation obtained theoretically is obtained; and a highly accurate equation of mill stretch is obtained. Thus an automatic sheet thickness control is performed basing on the equation, and the sheet thickness is maintained highly accurately.
