TUBES ROLLING METHOD IN TUBE ROLLING PLANTS WITH PILGER MILLS

摘要

FIELD: production of hot rolled tubes of large and mean diameters with lowered wall thickness and with increased relation D/S in tube rolling plants with pilger mills. ^ SUBSTANCE: method comprises steps of biting and deforming metal by means of strikers of rolls; rolling around - forming wall of tubes by means of polishing portions of rolls. At time moment of transition of joining points between strikers and polishing portions to vertical plane passing through axes of rolls, additional effort is created in feeding apparatus system; said effort is oriented in direction of sleeve-tube rolling away. ^ EFFECT: reduced wall thickness difference, elimination of stability loss of lengthwise profile.
