Beschreibung
Zusammenfassung:	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.
