Feed angles on the rolls were between 8° and 16° determined by Zhao et al. in 2014. Through the experiment, Pater et al. found 3-roll mills were 30% faster than 2-roll mills to produce thick tubes as the circumferential flow is increased in 2-roll mills at the surface layer, consuming more time and affecting both strains and energy consumption.

The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.
