METHOD OF PRODUCING STRIP OF VARIABLE THICKNESS AND STRIP OF VARIABLE THICKNESS Russian patent published in 2024 - IPC B21B37/16 B21B37/26 B21B1/08 B21B1/22 B21B1/26 B21H8/00 

FIELD: production of strip of variable thickness.

SUBSTANCE: billet is rolled by rolling stands to produce at least one section with thickness varying along its length. Change in thickness of the section with varying thickness is performed in one direction with preset intensity T/dt. During rolling of section with varying thickness, deviation from preset path of changing thickness of section with varying thickness, which does not exceed 17 % of specified thickness of this section, is controlled. Specified intensity T/dt of the section with varying thickness is calculated by the formula: T/dt = (|T1| + |T2|) / (Lv_i / Vd), where T1 and T2 are the first and second preset deviations, Lv_i is the length of the section with thickness varying along its length, Vd is the design speed of the strip behind the last rolling stand.

EFFECT: creation of a more technological method of producing strip of variable thickness is provided.
