摘要

FIELD: cold rolling in six-roll stand.;SUBSTANCE: in six-roll stand having pair of rolling rolls, pair of intermediate rolls and pair of backup rolls at least intermediate and rolling rolls engage with apparatuses for axial shifting. Barrel of each intermediate roll has length increased by shifting stroke and ground zone (x) near band edge at one side. According to invention upper intermediate roll is shifted in axial direction towards side As of drive unit and lower intermediate roll is shifted towards control side BS or vice versa. Said shifting is realized relative to neutral position (Szw = 0 mm) of mean portion (y-y) of stand symmetrically by the same value in direction of their axis (x-x). Shifting position is set in different portions along width of band by means of piecewise characteristics on base of different positions of beginning of ground zone relative to band edge. Configurations of ground zone of roll barrels are normalized by means of mathematical relations.;EFFECT: enhanced accuracy of rolled product geometry.;3 cl, 4 dwg
