Control Method for Eliminating Transverse Vibration Line Offset at Tail of Thin Strip in Short Process

Abstract

The invention discloses a method for eliminating a horizontal-vibration linear offset of the tail of short-process thin strip steel. The control method can eliminate the horizontal-vibration linear offset of the tail of short-process thin strip steel by control over centering of guide plates of rolling mills through measurement of rolling central lines, control over tail sleeving of loops, controlover the rolling force and roll bending force, control over the time sequence of a water system, control over the rolling tonnage of working roller, and control over the temperature of plate blanks.By adoption of the control method, the problem of the horizontal-vibration linear offset of the tail of ultra-thin CPS materials is solved; the technical problem that the plate shape of the tail of ultra-thin strip steel rolled through a short process is difficult to control, and consequentially, tail whipping and instable production are caused is solved; and high-quality and high-stability large-scale production of the ultra-thin strip steel rolled through the short process is realized.

Description

technical field [0001] The invention relates to the technical field of manufacturing hot-rolled strips, in particular to a control method for eliminating the deflection of transverse vibration lines at the tail of short-run thin strips, which is suitable for manufactured products with a thickness of 1.2 mm to 2.0 mm. Background technique [0002] Due to its technological characteristics, the CSP production line (continuous casting and rolling of thin slabs) is more conducive to the production of thin materials than conventional hot rolling. At the same time, under the promotion of "cooling with hot heat", the market potential of thin materials is huge. Facing the current situation of the steel industry and the homogeneous competitiveness of the market, the current product structure has been greatly adjusted, and the thin material plan has been greatly increased. [0003] The shape control of the strip tail is a difficult point in the production process of rolling thin produc...
