  • Method of rolling section billets
    Patent number: 4204416
    Abstract: The invention relates to a method of rolling section billets in which billets interconnected by bridges are successively formed from a slab in a number of grooves defined by a plurality of transversely juxtaposed passes, with subsequent separation of billets from one another by effecting a relative displacement of adjacent billets by prevailingly acting with a groove on one of the sides of the adjacent billets at an angle other than 90.degree. to the roll axis when the bridge thickness becomes equal to 0.01-0.3 of the groove height.

  • Method of rolling section billets
    Patent number: 4201075
    Abstract: A method of rolling section billets wherein a plurality of billets transversely interconnected by bridges are successively simultaneously formed from a slab in a number of grooves defined by a plurality of transversely juxtaposed grooves. The forming is effected in two stages by reducing the value of longitudinal tensile stresses in central portions of the billets at one stage by changing the position of zones of prevailing reduction transversely of the billets, with the subsequent separation of billets from one another.
