The tension value of Ut of hot roll strip mill. where σ is yield stress. Yield torque which strip bending deformation needed occupies a larger proportion in the total output torque. Bending torque changes according to the material properties and its size, so it is a very im portant to calculate the torque.

rolling load . Rolling force in hot rolling: Material flow in hot rolling is less homogeneous. Strain rate also affects the flow stress of the material. Further, friction conditions are rather unpredictable. Friction coefficient in hot rolling may be high – ranges from to Strain rate in hot rolling can be found out from the expression:

Roll separating force during rolling actually depends on three primary factors: the mean flow stress, the projective contact area and the shape factor. Mean flow stress depends on material only (including deformation history), and the shape factor is affected by the strain state and stress state in the deformation zone.

Jan 28, 2009· The rollers and the workpiece exert force on each other, and if either is absent, there is no force on either. The rollers exert force on the mill frame at their bearing points. There is no benefit to trying to make a distinction between who presses on who as it does not change what happens nor does it change the design of the rolling mill.
