Prof. Ramesh Singh, Notes by Dr. Singh/ Dr. Colton 13 Flat Rolling Analysis • Consider rolling of a flat plate in a 2-high rolling mill

POWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip tension.The total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc of contact ata distance 'a' from the line of centers of the rolls...The Calculation of Roll Force and Torque in Cold Strip Rolling with Tensions. D. Bland, H. Ford. Engineering. 1948. 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….

rolled to a thickness of 20 mm in one pass. The roll radius is 300 mm, and the rolls rotate at 100 rpm. Calculate the roll force and the power required. For annealed copper, it has a true stress of about 80 Mpa in the unstrained condition and …...Fig. 1.7.1: Rolling mill control From the above curves, we could understand the control of rolling mill. The solid curve, called plastic curve, represents the variation of rolling load with rolled thickness. As thickness reduces, roll force increases. This was shown earlier. The solid line represents the elastic deformation of the roll.

Flat Rolling •Roll Force: F= LwY avg •Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value...In the hot continuous rolling process, the main factor affecting the actual thickness of strip is the rolling force. The precision of rolling force calculation is the key to realize accurate on-line control. However, because of the complexity and nonlinearity of the rolling process, as well as many influencing factors, the theoretical analysis of the traditional rolling force prediction model ...

Accurate prediction of the rolling force is critical to assuring the quality of the final product in steel manufacturing. Exit thickness of plate for each pass is calculated from roll gap, mill spring, and predicted roll force. Ideal pass scheduling is dependent on a precise prediction of the roll force in each pass. This paper will introduce a concept that allows obtaining the material model ...KELK Strain Extensometers. Extensometers are simple, economical sensors attached to rolling mill housings to measure the strain in the housing posts resulting from roll force. Roll force can be derived from these measurements, but due to outside influences, these calculated results can never be as accurate as direct load cell force measurement.

Abstract. Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Kármán's equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be ...
