2017-8-9 THE DEVELOPMENT OF THE THEORY OF METAL ROLLING AND ITS APPLICATION TO ROLLING MILL CONTROL INTRODUCTION In the realm of process control it is the rigidness of specifica- tion upon the finished product which dictates the refinement neces- sary for adequate control. As the end product becomes more and more critical the solution to the control problem can no longer be

2010-10-4 A Closer Look at Machine Styles. Three-roll initial-pinch (see Figure 5) or single initial-pinch plate rolls generally are for light-capacity applications and may be electromechanical or hydraulic. They work by pinching the flat sheet between two vertically opposed rolls while the third, offset roll—or bending roll—moves upward to contact and then bend the sheet.

However it is very difficult to measure this variation in µµµµ, all theory of rolling are forced to assume a constant coefficient of friction . •For cold-rolling with lubricants, µµµµ~ 0.05 –0.10. •For hot-rolling ,

Four Roll Bending Machine Structure and Working Principle. According to the principle of three-point forming, the rolling machine makes use of the relative position change and rotation motion of the working roll, so that the sheet can produce continuous elastoplastic bending to obtain the workpiece with predetermined shape and precision.

2013-7-19 Contemporary plate rolling mills and pinch pass mills, which are unstable during the rolling process, are all statically indeterminate structures influenced by micro-scale parameters. The micro-scale parameters include bending deformations of the rolls and the side clearances between the chocks and the side surfaces of the housing window.
