Investigation of the Process of Screw Rolling in a Four-Roll
2018.11.15 According to the data presented in Fig. 10, it is necessary to spend 17.49 kJ (3 × 5.83 kJ) for rolling in the three-roll mill and 16.46 kJ (2 ××7.93 + 2 ××0.3 kJ) for rolling in the four-roll mill. In other words, the procedure of form-changing in the case of rolling in a four-roll mill requires less (by 6%) energy than for the threeroll ...

A Comparative Analysis of Forming Railway Axles in 3- and 4-Roll ...
2020.7.10 The maximum axial load is 580.4 kN for a 4-roll mill and 455.1 for a 3-roll mill. An interesting fact is the occurrence of a negative load acting on the chuck when the biggest diameter steps are formed. This indicates that the rolling process runs on an independent basis and that the chuck prevents the axial movement of the workpiece.

A comprehensive review on incremental deformation in
2022.2.15 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.
