    The calculation of rolling force - Innoval Technology

    The calculation of rolling force. When manufacturing sheet products it’s important to understand the rolling force. This is because you need it to set the appropriate roll gap on the mill, accounting for the stretch of the stand. The prediction of rolling force can be challenging due to the large number of inter-connected process variables

    Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the

    The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm ‘a’ λ =0.5 for hot rolling and 0.45 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 = 2P.a Consider two high roll mill as shown in the figure
