[0074] This embodiment provides a method for identifying the risk of disc shear and edge blocking in a cold rolling production line. Decisions are made by acquiring hot rolling data and cold rolling real-time data, combined with the genetic influence of hot rolling quality problems and the strip operation at the entry section of cold rolling. In the hot rolling process, the cambering caused by the difficulty in rolling control of the head and tail parts of the strip, the loss of width of the strip during the rolling process, and other parts with high edge plugging risks are pre-identified. The edge blocking risk caused by the characteristics of the future material and the edge blocking risk caused by the operation state are combined to carry out risk identification, which can provide production early warning for the edge blocking problem; the method can be realized by electronic equipment, and the electronic equipment can be a terminal or a server.

Abstract

The invention discloses a cold rolling production line circle shear edge blocking risk identification method and system. The method comprises the steps that edge blocking risk identification caused byhot rolling incoming material characteristics is achieved on the basis of hot rolling incoming material data, and edge blocking risk identification caused by cold rolling strip steel operation deviation is achieved on the basis of cold rolling deviation monitoring data. On the basis of a hot rolling and cold rolling data acquisition platform and cold rolling production line process monitoring information, a set of edge blocking risk identification method based on hot rolling incoming material quality data and a cold rolling equipment operation state is established, and production early warning can be provided for an edge blocking problem, so that related personnel can intervene in advance, unplanned shutdown can be reduced, and a guarantee is provided for stable operation of equipment.

Description

technical field [0001] The invention relates to the technical field of mechanical automation control, in particular to a method and a system for identifying the risk of disc shearing and plugging of a cold rolling production line. Background technique [0002] In the traditional pickling-cold rolling unit, after the hot rolled coil is uncoiled, sheared, welded and pickled in the cold rolling line, a disc shearing device is arranged in front of the entrance of the cold rolling mill, and its function is to trim the strip according to the specified width. Both sides of the steel provide a guarantee for the stable operation of the cold rolling process. The system sets different openings of disc shears according to incoming materials of different widths, and performs edge trimming operation on the running strip. Short side filaments with constant length. In the process of trimming, it is necessary to keep the width of the edge wires on both sides as consistent as possible. Howe...
