(PDF) Methodology for Calculation of Rolling Load and Forces Acting On
In this paper the concentration is given to the calculation of rolling load and the forces acting on the gears of steel rolling machine. After that power and torque required is calculated for the rolling load and the gear forces simultaneously which is further useful for designing and analysis the gear used in gearbox of hot rolling machine.

The Calculation of Roll Force and Torque in Hot Rolling Mills
There is close agreement between the calculated and measured roll loads, but the roll torque is over-estimated slightly by the theory, above reductions of about 30 per cent in thickness. References Bailey, W. H. 1951 British Iron and Steel Research Association Report MW/AA/28/51*.

Deformation Processing
Prof. Ramesh Singh, Notes by Dr. Singh/ Dr. Colton 1 Deformation Processing
Fundamental concept of metal rolling 1) The arc of contact between the rolls and the metal is a part of a circle. 2) The coefficient of friction , µµµµ, is constant in theory, but in reality µµµµvaries along the arc of contact. 3) The metal is considered to deform plastically during rolling. 4) The volume of metal is constant before and

Optimization of mill performance by using
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
