METHOD OF ADJUSTING THICKNESS OF COGGED INGOT FED THROUGH MULTI-STAND MILL, FEED-FORWARD AND/OR CLOSED-LOOP CONTROL DEVICE, AND ROLLING MILL STAND Russian patent published in 2013 - IPC B21B37/26

Abstract RU 2477661 C2

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy, particularly, to strip hot rolling at multi-stand mill 1. First section G-1 of cogged ingot G is rolled to first thickness at outlet H3. Second section G-2 of said ingot is rolled to second thickness H3' that differs from said first thickness H3. Transition from said first thickness to second thickness occurs at speed V₀ of feeding ingot G to mill stand line 2 that is adjusted as the function of ingot speed V_g of leaving unit 6. Said unit 6 is located ahead of mill stand line 1 in direction of bulk flow and may be operated irrespective of other units located ahead of said line 2.

EFFECT: higher efficiency of rolling.
