Stainless steel cold continuous rolling unit

By adopting a double eccentric design in the stainless steel cold rolling mill, the offset of the center line of the support roll and the work roll is set to be greater than the offset of the center line of the intermediate roll by a first preset distance, which solves the problems of roll system stability and mill life, and realizes the stability of the roll system and the protection of the work roll.

AI Technical Summary

Technical Problem

Existing six-roll stainless steel mills cannot simultaneously address the issues of roll system stability and mill lifespan, especially when rolling high-yield-strength stainless steel. The improvement in roll system stability is limited while the rolling force is too large, leading to easy deformation and damage of the work rolls.

Method used

The stainless steel cold rolling mill with a double eccentric design has a first preset distance between the center line offset of the support roll and the work roll, which is greater than the center line offset of the intermediate roll, forming a larger triangle to ensure the stability of the roll system, while reducing the rolling force on the work roll and preventing work roll deformation.

Benefits of technology

The double eccentric design improves the stability of the roll system, reduces the rolling force on the work rolls, extends the service life of the rolling mill, and achieves efficient fully continuous rolling.

Abstract

The invention provides a stainless steel cold continuous rolling unit, which relates to the technical field of rolling equipment and comprises a rolling mill section, the rolling mill section comprises a plurality of rolling mills arranged in sequence, and each rolling mill comprises a working roll, a middle roll and a supporting roll. The symmetrical center line of the cross section projection of the supporting roller in the direction perpendicular to the extension direction of the supporting roller is deviated by a first preset distance relative to the symmetrical center line of the cross section projection of the middle roller in the direction perpendicular to the extension direction of the middle roller; the symmetrical center line of the cross section projection of the working roller in the direction perpendicular to the extension direction deviates by a second preset distance relative to the symmetrical center line of the cross section projection of the middle roller in the direction perpendicular to the extension direction, and the first preset distance is larger than the second preset distance. The roll system of the rolling mill adopts a double-eccentric design, and roll system stability and rolling mill service life can be both considered.
