Analysis of Driving Torque of 20-High Sendzimir Mill


Because of the complex roll system of the 20-High Sendzimir mill, the calculation of the driving torque is different from the 4-High or 6-High rolling mill, except the rolling torque MR, the friction torque Mf cannot be ignored, and the friction torque Mf is consist of the friction torque caused by the rolling friction between the rolls Mf R and the friction torque to overcome the friction in the backing bearings MfB. On the basis of the force analysis of the roll system, the driving torque of the 20-high Sendzimir mill was calculated and analyzed, include the torque MR, Mf, MfR and MfB, the composition and distribution law have been gained; what’s more, the contact stress between rolls was also calculated, these are significant for the design of the 20-High Sendzimir mill.
