  • Roll Pass Designing In Continuous Bar Mills

    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.
