Abstract

1498642 Straightening by skew rolling VALLOUREC (USINES A TUBES DE LORRAINE - ESCAUT ET VALLOUREC REUNIES) 22 Jan 1975 [25 Jan 1974] 2887/75 Heading B3M A rod or tube 1, Fig. 1, to be straightened is passed between skewed rolls 2 and 4 by means of skewed feed rollers 30-33 located a short distance upstream and downstream of feed rollers 30-33, the distance being, for bars or tubes having a diameter/thickness ratio below 10 between 4 and 8 times the diameter of the thickest bar or tube to be treated. For tubes with a diameter/wall thickness ratio of between 10 and 35, the distance is between 3 and 6 times the diameter of the thickest tube to be treated. The roll 2 may be of hyperboloidal shape and be supplemented by a further pair of rolls 6 and 7 arranged on either side of the rod or tube for maintaining it in a vertical plane during deformation. In an alternative form Fig. 5, the rolls 2 and 4 are replaced by a central roll 34 and two rolls 35 and 36 on opposite sides of the central one.
