that roll load and forward slip decrease with increasing rolling speed due to the decrease in contact ratio and friction. The predictions of the model are veried using mill trials under industrial conditions. For both thin strip and foil, the load predicted by the model has
With the correct strip tension now obtained, the mill accelerates to rolling speed. For further reversing passes the strip remains wound on the two tension reel mandrels. The strip tension is measured at the reels and the thickness is measured by the two x-ray thickness gauges, one entry side and one exit side of the mill stand.

In their setup, the desired strip roughness can be achieved by combination of different rolling forces on the two mill stands. However, most temper rolling mills use a single mill stand. In these cases strip tension might be an alternative, as it is widely adjustable and influences the transfer ratio via its effect on the roll pressure.
