Problems solved by technology

[0004] In addition, sometimes the edge of the strip does not completely cover the sensor of the shape sensor, resulting in errors in its feedback signal. Large rolling force fluctuations, these factors will cause edge thinning and cannot be accurately identified by the shape meter

Abstract

The invention relates to the technical field of shape control of metallurgical steel rolling equipment, in particular to a novel rolling mill external cooling device and an operating method for segmentally and flexibly adjusting the roll shape, which can flexibly adjust the local thermal crown of the roll to form a good roll gap shape and The parts that cannot be identified by the shape meter are compensated, and finally the flatness of the overall shape is improved, and high-quality strips are rolled.

Description

technical field [0001] The invention relates to the technical field of plate shape control of metallurgical steel rolling equipment, in particular to a novel rolling mill external cooling device and an operating method thereof for segmentally and flexibly regulating the roll shape. Background technique [0002] Shape is an important index to measure the quality of strip steel, and shape control is the core technology in the strip rolling process. A stable roll gap is the premise to achieve a uniform thickness of the strip after rolling and improve the yield of the plate. With the market's urgent demand for high-quality strips, good strip formation has become the basic requirement for high-end strips, and has also become the pursuit goal of manufacturers. For this reason, a series of strip shape control technologies have been formed successively, such as the most commonly used roll tilting, hydraulic roll bending method, etc. The emergence of these technologies has greatly i...
