The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm ''a'' λ = for hot rolling and for cold rolling. The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt = Consider two high roll mill as shown in the figure.
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product.
parameters. A largedeformation constitutive model applicable to the calculation of roll force and torque in heavyreduction rolling was presented by Byon, Kim, and Lee (2004). 3D FE analysis coupled with the proposed constitutive models has been carried out to calculate workpiece deformation and the rolling force in their investigation. An
Rolling processes 51 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 (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
