Simplified Calculation of the Bending Torques of Steel Sheet and

bending torques of the steel sheet at contact points with the working rollers are first calculated and then the straightening forces are determined. In straightening steel sheet, The speed of the rolling mill is set at 10 rpm, giving a roll surface velocity of 70.69 mm/s. It was found necessary to use guides for the bars, both at entry and exit, in order to minimize sideways bending. The parameters monitored during the experiments include the temperature, roll force and torque.Roll Torque an overview ScienceDirect Topics

A simplified method to calculate the rolling force in hot rolling

In this paper, a new specific roll pressure formula is derived from the Navier-Stokes equation (N-S equation) by the hydrodynamics method (HM) with assumptions that strip materials take the characteristics of viscous fluid during plastic deformation of hot rolling processes. Results predicted by this HM formula, Sims θ = 180° (or π radians) This is a situation where the force vector points directly into r. Again, shoving toward the axis of rotation isn't going to cause any rotation either and, once again, the mathematics Calculating Torque With Examples ThoughtCo

Data-Driven Roll Pass Design of Wire Rod Mills ResearchGate

A computational method for pass design of the four-roll rolling process for sizing of round sections. The four-roll rolling process (4RP) enables the further evolution of sizing processes in1. Introduction. For accurate dimensional control of a hot-rolling process, the roll-separation force and the torque are the most important quantities for both forward production planning and real-time process control. Additionally, the roll-separation force and the torque during hot rolling are limited by the equipment of the rolling mill.Calculation of Deformation-Related Quantities in a Hot-Rolling
