A method of making billets, whereby a composite billet is produced by continuous casting or rolling, which billet is star-shaped in cross section and has at least two ray members disposed symmetrically relative to the central longitudinal axis of the composite billet; the base of each star ray member of the composite billet at the place of its juncture with the central portion thereof is selected to be 0.72 to 2.3 of the ray member height, the other base being 0.5 to 1.0 of the ray member height, the lateral sides of the ray member may differ in length; the segregation zone is caused to concentrate in the central portion of the composite billet selecting appropriate relationship between geometric dimensions of the composite billet and by creating favorable conditions for producing the composite billet; thereafter, the ray members are severed from the central portion of the composite billet by means of rolls in a rolling mill, this being performed by subjecting one of the lateral sides of the ray member to the action of an appropriately grooved roll.

Method of making billets

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

Apparatus for severing moving members such as ingots, tube skelps and rolled stock, comprising cooperating cutters disposed transversely to the direction of movement; power means for simultaneously urging the cutters together from opposite sides of the member being cut; pneumatic means for urging the cutters apart; and means for automatically disengaging the cutters from the severed member through use of the force of the moving member.
