摘要
A method for compensating for the asymmetric plate shape of a strip mill, which is used to compensate for the asymmetric plate shape introduced to the strip during the processing by the strip mill in the current technical conditions. A non-linear asymmetric dummy roll shape contour curve is formed by polishing the upper and lower work rolls, and a non-linear asymmetric dummy roll slit between the drive side and the work side is formed between the upper and lower work rolls. Is. The strip rolling mill in the current technical conditions is currently used frequently and is a double roll rolling machine driven by the drive side of the work roll, or a quadruple that adds a support roll to the double roll rolling mill. It is a rolling mill or a multiple rolling mill that further adds an intermediate roll. The present invention compensates for an asymmetric dummy roll slit in a work roll, and presents an asymmetrical plate shape defect caused in a processing process by a strip rolling mill under the current technical conditions, and an obvious Can reduce or eliminate potential asymmetric plate shape quality problems, while reducing production stability failures such as misalignment, meandering and multi-layer rolling caused by asymmetric plate shapes during production on strip mills Can be made.
