Features of Three Roller Rolling Machine. The motor power can be calculated according to the following formula. Johnson The bending of plate using a three roll pyramid type plate bending machine J.
Windseaker1 Sorry for being late getting back yes the bend formula works for rolling as well when you roll a plate you are bending it on a large radius the metal still has to shrink on the inside of the neutral line and stretch on the outsideTo get a finished diameter that you want you have to compensate by adding or subtracting part of the metal thickness from. These two methods are combined in one single machine to work smoothly and efficiently. P the total pressure acting on the roller kN.
All machines are really designed to function best when used to half their working. The slab thickness is normally 220 mm but also 290 and 140 mm exist.
