  • Looper and tension control in hot rolling mills A survey

    Jul 01 2007 · 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 0.8–20 mm. Fig. 1 shows a typical layout of a hot strip mill.

    Rolling processes 5-1 introduction Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working called hot rolling owing to the large amount of deformation required.

  • 5.2.3 The Ring Rolling Process Forging Industry Association

    Ring rolling is a hot forming process that produces seamless rings varying in size from a few inches in diameter and weighing less than one pound to over 25 feet in diameter and face heights approaching 10 feet. The process and equipment are similar in principle to rolling mills used for plate. In both processes the metal is rolled between two rolls which move toward each other to form a

    The main drive system using for four-high mill is usually a double closed loop DC motor speed regulating system. Generally the speed controller and current controller are PID controllers and the parameters of controllers are determined by the engineering design method. Once disturbance occur the control effects are often just passable. In this paper fuzzy logic is used to set the

    CiteSeerXDocument Details (Isaac Councill Lee Giles Pradeep Teregowda) This paper deals with the problem of looper control for tension-free rolling. Conventional controllers cannot deal eectively with unmodeled dynamics and large variations which can lead to scrap runs and damages to machinery. Therefore a fuzzy controller has been designed to use the expert knowledge of the operators
