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.

In this paper we have suggested the methodology for calculation of forces acting on the gear by using theory of hot rolling. In this paper the analysis process is define by comparing the power and torque available at the input and the total power and torque required for hot rolling process.
Roll wear is amongst the key criteria for devising a rational roll pass design. Rolls in a hot mill have to withstand radial loads up to 12 MN and high temperatures in the range of 900 to 1300 oC. In addition to the obvious need for resistance to breakage, there is the continuing component of roll wear that is critical to the economics of ...
The HSMM model performs a variety of calculations to simulate the physical process of rolling steel in a hot strip mill. To model the various mechanical and thermodynamic processes during hot rolling, these calculations rely on equations from the basic principles of physics and on equations developed from theories of rolling mill researchers.
