FIELD: metallurgy. ^ SUBSTANCE: procedure consists in control of rolling mill containing rolling stand (1) with working rollers, roller bed (2) positioned on its inlet side and device of control (5). Levelling a front edge of breakdown relative to an inter-roller gap is ensured with control of the rolling mill when working rollers (6) rotate with circular velocity (vU), while roller bed is controlled so, that initial edge (14) of stripped rolled material (8) reaches inter-roller gap (g) at inlet velocity exceeding circular velocity (vU). Circular velocity (vU) and inlet velocity (vE) are matched between them by device of control (5) so, as to at least decrease possible skew of initial edge (14) relative to inter-roller gap (g) due to this matching. The rolling mill, data medium and control device are furnished with corresponding equipment. ^ EFFECT: raised efficiency and output of accepted product at strip rolling. ^ 17 cl, 5 dwg |
