  • What is a Reversing Mill?

     · A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge. Reversing mill plants are preferable for rolling silicon steels and other special ...

  • Finishing Mill

    B. López, RodriguezIbabe, in Microstructure Evolution in Metal Forming Processes, 2012 Thermomechanical processes based on dynamic recrystallisation. In rod rolling, the high strain rates in the finishing mill lead to very short interpass times (below 50 ms) compared with reversal or strip rolling. Under these conditions, the interpass time is not long enough for the ...
