Hot pilgrim rolling mill for tube rolling - has roll cage driven oscillatory via crank mechanism

摘要

A hot pilgrim mill for rolling tubes comprises a roll cage driven in an oscillatory manner via crank mechanisms, the cage being balanced by balancing means. The rolls are rotated by fixed racks engaging with pinions mounted on the roll shafts. The amplitude of oscillation is greater than in conventional mills, the equipment also being cheaper and more reliable than conventional mills.
