Proposed herein is a method of producing shaped rolled sections, residing in that the blank is subjected to plastic working by being rolled and cold formed in rolls, with the former put in between the blank and the rolls; the former being made as a rod-like structure arranged lengthwise the axis along which plastic working occurs, whereas the vacant end thereof is brought outside the zone of plastic working.

Method of producing shaped rolled sections

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

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.
