Advanced Process and Quality Control in Hot Rolling Mills Using Eddy Current Inspection Autor: SVEN KLING Speaker: Markus WITTE PRÜFTECHNIK NDT Ismaning, Germany +49 89 99 616 152 Abstract Eddy current testing is a common method for the surface inspection of semifinished products.
Keywords: rolling mill, multistand mill, thickness control, tension control, flying gauge change, nonlinear control, flatness based control. Abstract A multistand rolling mill is a highly complex coupled nonlinear system. If the operating point is changing in a wider range the nonlinearities can no longer be neglected in the controller ...
Technological controls for cold rolling processes Rolling of flat metal products is a complex process where the quality of the product is influenced by various factors like incoming material, mechanical and electrical equipment, lubrication and control strategies. For highend performance in terms of material quality and productivity,

control for rolling mill vibration can be obtained and is shown in Figure 3(b). To achieve compensation, the interaction force between the work roll and the back roll and the vibration.
172007· This paper considers some of the control issues in hot rolling mills. Hence to set the context, first we give a brief description of a typical process. The role of a hot strip mill process is to roll the slabs produced in a continuous casting process and produce strips of thickness –20 mm. Fig. 1 shows a typical layout of a hot strip mill.
principle, Steel industry, Tandem rolling mill, Looper control, Strip te nsion control. 1. INTRODUCTION In the metals industry, tandem hot strip rolling mills are used for rolling out thick semi nished products,, slabs, to thinner at products. The product, which is often referred to as strip, is clamped in each mill .

Rolling Mill Automatic Flatness Control (AFC) System Description The TelePro/SSE AFC system consists of integrated control of work roll bending, HGC tilting, variable roll crown shifting (if available) and multizone work roll cooling to minimize deviations .
Tags Rolling Mills, Slitting Lines; Rolling Mill History. Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519.
Tandem cold rolling process is a nonlinear complex system with external and internal uncertainties and significant disturbances. The improvement in the quality of the final output depends on the control strategy of centerline thickness and interstand tension. This paper focuses on interstand tension control problem in 5stand tandem cold rolling mills.
rolling mill roll eccentricity control. H #x221E Control system for tandem cold mills with roll . In order to meet the requirement for higher thickness accuracy in cold rolling processes it is strongly desired to have high performance in control units.
Abstract: Considers some of the distributed aspects of the control of modern metal rolling mills. Such mills have a range of ever more ambitious targets, for example product quality, yield, metallurgy and throughput. These aims are supported by high levels of mill sophistication, in terms of plant equipment, instrumentation, actuators and control hardware.
