only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone. Besides “normal rolling conditions” - a stable, theoretical assumption - mills experience many different changes in rolling conditions. After a roll change or a mill stop rolls need some time to return to stable

Rolling processes - الرئيسية

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.

Basics of Rolling and Rolling Mills – IspatGuru

May 30, 2013  Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration – This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.

A typical hot rolling mill consists of a reheat furnace, sizing press, roughing mill, finishing mill, runout table and coiler, as shown in Figure 1. Among these components, the finishing mill, which is composed of two work rolls (WRs), two intermediate rolls (IMRs) and two backup rolls (BURs) supporting them, has a major influence on the ...

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 Process: Working, Application, Defects, Type of ...

Definition of Rolling process: Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers, thus the uniform thickness is formed. To do this, the temperature is essential. There are two types of processes. One is Hot rolled and another is Cold Rolled.
