[0074] This embodiment provides a method for identifying the risk of side disc shearing and blocking in a cold rolling production line. Decisions are made by acquiring hot rolling data and cold rolling real-time data, combining the influence of hot rolling quality problems genetics and the operation of strip steel at the entrance section of cold continuous rolling In the hot rolling process, carry out risk pre-identification on parts with a high risk of edge blocking, such as camber bends caused by difficult rolling control of the head and tail parts of the strip in the hot rolling process, and strip width loss during the rolling process. Combining the risk of edge blocking caused by material characteristics and the risk of edge blocking caused by operating conditions for risk identification can provide early warning of production for edge blocking problems; this method can be realized by electronic equipment, which can be a terminal or a server.

Abstract

The invention discloses a method and system for identifying the risk of side-cutting and blocking of discs in a cold-rolling production line. Risk identification of edge blocking caused by running deviation of cold-rolled strip realized by monitoring data. Based on the "hot rolling-cold rolling" data acquisition platform and the process monitoring information of the cold rolling production line, the present invention establishes a set of edge blocking risk identification methods based on the quality data of hot rolling incoming materials and the operating status of cold rolling equipment, which can be aimed at The problem of edge blocking provides early warning of production, so that relevant personnel can intervene in advance, thereby reducing unplanned downtime and providing guarantee for the 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 system for identifying the risk of disc shearing and blocking in a cold rolling production line. Background technique [0002] In the traditional pickling-cold rolling unit, after the hot-rolled coils are uncoiled, sheared, welded, and pickled in the cold-rolling line, a disc shearing device is arranged before the entrance of the cold tandem mill, and its function is to trim the strips according to the specified width. Both sides of the steel provide guarantee for the stable operation of the cold rolling process. The system sets different openings of the disc shears according to the incoming materials of different widths, and performs edge trimming on the running strip steel. For the trimmed edge wire waste, it is equipped with a scrapping edge shear device, which is used to cut the edge wire waste into pieces. Short edge filaments with constan...
