METHOD OF HOT ROLLING AT CONTINUOUS WIDE-STRIP MILL Russian patent published in 2016 - IPC B21B1/26 

FIELD: metallurgy.

SUBSTANCE: rolling of strips of preset width B mm with specified bulge of transverse section not exceeding 0.06 mm is performed at the continuous wide-strip mill. This results from rolling sequentially not over 30 strips of width B₁<(B-50) mm for warming the roll bodies and at least 2000 tons of rolled stock of width B₂ mm within the limits of one run of the rolls. Note here that B≤B₂≤(B+50), and not over 1050 tons of rolled stock of preset width B at the end of working rolls run.

EFFECT: higher precision of geometrical sizes over the strip width.
