DEVICE TO DISPLACE MANDREL AT PIPE ROLLING MILL

摘要

FIELD: process engineering.SUBSTANCE: invention relates to metallurgy, particularly to pipe rolling mills. Pipe rolling plant comprises multiple stand pipe rolling mill with two or more rolls in stands and engaging/disengaging mechanisms. One engaging/disengaging mechanism is arranged at pipe rolling mill inlet to interact with the mandrel rear shank. Second engaging/disengaging mechanism is arranged at the mill outlet area to interact with the mandrel front shank. This plant comprises adjustment means to coordinate operation of said mechanisms.EFFECT: production of thin-wall different-length pipes.13 cl, 23 dwg
