Abstract

1,084,142. Rolling. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY I PROEKTNO - KONSTRUKTORSKY INSTITUTE METALLURGICHESKOGO MASHINOSTROENIJA. Jan. 6, 1965, No. 530/65. Heading B3M. External helical grooves 7 are produced on a bimetallic tube 1, 2 by three driven rolls 3, arranged at 120 degrees to each other, with their axes lying at an angle to the tube axis, equal to the angle of the helix. Each roll comprises a first set of discs 4, having the same peripheral shape but different diameters, a second set 5, having gradually thickening sections of the same diameter, and a third set 6 having a thinner cross-section and greater diameter. During rolling, rolls 3 rotate and feed the tube axially. The tube may have more than two layers.
