From an approximate theory, equations are derived for roll force and torque with and without front and back tensions applied to the strip. Where tensions are applied the calculations for each pass take about an hour; without tensions, and with the use of curves given in …

However, the accurate roll torque and roll separating force for broadside rolling in a roughing sequence are the prerequisite for the automatic control of the rolling mill, . Motivated by the information above, the present paper proposes an analytical solution to the total power functional for broadside rolling.

Roll force is a key parameter in the process control of hot strip rolling, and its computational accuracy directly determines thickness precision, strip shape quality and rolling stability, . Therefore, the online calculation model of roll force with high accuracy is taken as the core for substantial studies at home and abroad, . According to ...

Following are the results of the calculation of the roll load for various passes of the material through the rolling mill on the basis of the output voltage obtained in the strain indicator circuit. III. CALCULATION OF LOAD FROM W.L. ROBERT‟S FORMULA f V c l e Where f: Specific rolling force (force per unit width of material) V c

The force that resists the motion of a body rolling on a surface is called the rolling resistance or the rolling friction.. The rolling resistance can be expressed as. F r = c W (1). where . F r = rolling resistance or rolling friction (N, lb f). c = rolling resistance coefficient - dimensionless (coefficient of rolling friction - CRF)

Tire rolling resistance F RR. The force due to rolling resistance is a function of many factors such as tire design, inflation pressure, vehicle weight, and speed. The primary mechanism behind rolling resistance is the deformation of the tire as it rolls under the weight it supports, and the friction of contact with the road surface.

According to ...

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.

Rolling Friction Calculator. Rolling friction is also called as the rolling resistance or rolling drag. It is the frictional force which opposes the movement of an article which is moving through a surface.
