  • Patent number: 4381658
    Abstract: The method of I-section rolling in a continuous mill includes successive rolling of a bar in horizontal slitting passes, horizontal closed roughing beam passes with alternate directions of the slope of the flange outer sides, vertical reduction passes and finishing universal beam passes; and it also includes working of bent-out live flanges of the bar prior to reversal of the direction of the slope of the flange outer sides in the closed beam passes. All the passes are arranged one after another according to the production process in a combination which provides for producing an I-section. In all the horizontal closed roughing beam passes, the rolling of the bar is effected with the flange outer sides having a slope of 15-100 percent on the live flanges and a slope of 8-12 percent on the dead flanges. In the vertical reduction passes the outer sides of the bar are worked to slopes corresponding to the slopes of the outer sides of the dead flanges of the succeeding horizontal closed roughing beam pass.

  • Patent number: 4378687
    Abstract: A method for rolling H-sections in a continuous mill comprises bevelling of the leading edge of a billet on the faces which are horizontal during rolling and subsequent rolling thereof in slitting and beam passes. The end of the billet is bevelled at an angle of 20.degree.-30.degree. relative to the horizontal axis thereof.
