• ### Roll Separating Forcean overview ScienceDirect Topics

The roll separating forces obtained in a single-stage pass of 55 reduction and two two-stage passes of 14/39 and 20/33.6 reduction are given in Figure 15.4, measured when rolling the softer AISI 1008, deep-drawing quality steel. Figures 15.2 and 15.4 are quite similar. The dynamic response of the mill is also similar to the previously observed behaviour. Jul 29, 2010 · If the finished stand delivers at a speed of 12 mps, then stand 1 must run at 0.39 mps 0.3 x 3467 = 12 x 113. In this case the constant is about 1050, i.e., if you know the areas, you can immediately calculate the exit speeds. And, you have no problems in setting the speed at each stand, as each stand has its own independent motor.
