A continuous mill consists of several stands of rolls arranged in a straight line (in tandem), with each succeeding
stand operating with roll surface speed greater than its predecessor. This type of mill is in very common usage
for rolling strip, sheet, billets, bars, rods, etc. Any part of the workpiece, after pass through the roughing,
intermediate and finish stands, is rolled from initial shape into the finish one, and emerges from the last roll stand.
A semi-continuous mill comprises also a reversing roughing stand for reducing the piece prior to entering the
continuous mill for reduction to the finished shape. This arrangement gives moderately high production with
lower first cost than a continuous mill.
