Abstract (en)
[origin: EP1170068A1] A three-roll-type reducing mill (1) including three forming rolls (19,23) brought into contact with an outer periphery of an electro-resistance-welded steel tube (P) for reducing its diameter. Two left and right sliding brackets (22) respectively mounted with two follower forming rolls (23) are slidden symmetrically with respect to a center of a main forming roll (19) and simultaneously only by rotation of a single adjusting screw shaft (27), thereby enabling the diametrical reduction of the steel tube (P) to be adjusted on-line and speedily. <IMAGE>
