Abstract
PURPOSE: Extremely small diameter working roll and relatively large diameter roll are combined to efficiently perform a high reduction rolling.
CONSTITUTION: A rolling system consists of a center working roll 1 and radially arranged periphery working rolls 2,2', 2". A strip 3 advanced from the upper portion of the periphery working roll 2 at obliquely above, passes through A between the periphery roll 2 and the center roll 1, and through B between the center roll 1 and the bottom periphery roll 2' enclosing the center roll 1. The strip, further enclosing the center roll 1 and contacting with the other periphery roll 2" at obliquely above, moves upwards. When the center roll working roll is extremely small as in this invention, in which the rolling reaction and the rolling torque are reduced, the periphery rolls can be made smaller without losing strength. For such small working center roll, super hard alloy roll can be used.
