Embodiment Construction

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] attached figure 1 It is a flow chart of a method for tracking a weld seam of a cold rolling processing line provided by the present invention. A method for tracking a weld seam of a cold rolling processing line provided by the present invention includes the following steps:

[0023] Area division step: divide the cold rolling treatment line into several tracking areas from the initial position where the weld seam appears, so that a tension roller is arranged near the exit of several tracking areas, as the speed reference tension roll of this tracking area, in several tracking areas Includes fixed-length tracking regions and variable-length tracking regions.

[0024] Such as figure 1 As shown in , taking the unit from the uncoiler to the tension roll as an example, the cold strip production line is divided into the first area 1, the secon...

Abstract

The invention relates to a cold rolling processing line welding seam tracking method which is applied in a cold rolling processing line. According to the welding seam tracking method, welding seam tracking is conducted in a subarea mode, so that the welding seam tracking is made to be more accurate. The method comprises the steps that the cold rolling processing line is divided into a plurality of tracking areas, a tension roller is arranged in an outlet of each tracking area and is used as a speed standard tension roller of the corresponding tracking area, and the tracking areas comprise fixed-length tracking areas and non-fixed-length tracking areas; when a welding seam is generated in the cold rolling processing line, welding information corresponding to the welding seam is generated, and the welding seam information of the welding seam is stored in real time; when the welding seam enters one tracking area, collection of the roller face line speed of the speed standard tension roller of the corresponding tracking area is started, the roller face line speed is used as the moving speed standard of the welding seam in the tracking area, and the real-time stroke of the welding seam in the corresponding tracking area is obtained; the real-time position of the welding seam is rectified in the outlets of the non-fixed-length tracking areas; area information groups of all the tracking areas are stored in real time.

Description

technical field [0001] The invention relates to a seam tracking method, in particular to a seam tracking method for a cold rolling processing line. Background technique [0002] With the rapid development of computer automatic control technology, the automation degree of cold rolling processing line, especially the cold rolling strip production line is getting higher and higher. At the same time, it is required to track the welding seam of the strip steel more accurately. The simple photoelectric physical detection method cannot be used to detect the weld seam, but the weld seam must be effectively tracked throughout the production line so that when the weld seam passes through a certain equipment After the distance, upload and send a certain parameter, or start and stop a certain equipment, and realize automatic changes to various process parameters such as strip tension and running speed. Because factors such as changes in tension in the induction heating furnace and chan...
