METHOD, AS WELL AS ROLLING MILL FOR ROLLING MADE BY POURING INTO INGOTS OF ROLLING MATERIAL, CONTROL AND/OR REGULATION DEVICE FOR ROLLING MILL, COMPUTER-READABLE PROGRAM CODE FOR CONTROL AND/OR REGULATION DEVICE, AS WELL AS STORAGE MEDIUM Russian patent published in 2016 - IPC B21B1/22 

FIELD: metallurgy.

SUBSTANCE: before rolling, rolled stock has form of a truncated pyramid with a base area (4), a top area (6) and four side areas (8a, 8b, 10a, 10b). Production rectangular products without distorting their shape provided due to that during a first rolling pass sequence, two opposite side areas (10a, 10b) of rolled stock (2) are rolled in a first direction (R₁) in such a way that, at end of first rolling pass sequence, all of cross-sectional areas (4, 6) of rolled stock (2) that are oriented transversely in relation to rolling direction have same surface area, rolled stock (2) is turned through 90°, during a second rolling pass sequence, same two opposite side areas (10a, 10b) of rolled stock (2) are rolled in a second direction (R₂), transversely in relation to the first direction (R₁).

EFFECT: redistribution of material of rolled stock (2) after first rolling pass sequence makes it possible for desired geometry to be set fully automatically with high precision, in particular without use of vertical rolling stands.
