Tracking and detecting system and method for head and tail billet positions of continuous casting

Abstract

The invention discloses a tracking and detecting system for head and tail billet positions of continuous casting. The system comprises an image collecting unit, an image processing unit, a displacement detecting unit and a tracking and monitoring unit, wherein the image collecting unit is used for collecting image information of a continuous casting billet in real time; the image processing unit is used for recognizing whether the billet head or billet tail of the continuous casting billet appears or not according to the image information, and sending signals of 'billet head in position' or 'billet tail in position' when the billet head or billet tail appears; the displacement detecting unit is used for detecting signals representing the casting length of the continuous casting billet in real time; and the tracking and monitoring unit is used for determining the casting length of the head billet or tail billet according to signals received from the displacement detecting unit, and calibrating the determined casting length of the head billet or tail billet according to the signals of 'billet head in position' or 'billet tail in position'. Correspondingly, the invention further discloses a tracking and detecting method for head and tail billet positions of continuous casting. By means of the system and method, the head and tail billet positions can be tracked and detected, accumulative errors can be eliminated, and thus continuous casting production process control precision and quality control precision are guaranteed, and normal production and product quality are preventedfrom being affected.

Description

technical field [0001] The invention relates to the field of continuous casting process detection and control, in particular to a continuous casting head and tail blank position tracking detection system and method. Background technique [0002] In the steelmaking and continuous casting production line, the accuracy of the position tracking and detection of the head blank and the tail blank directly affects the control precision and quality control precision of the continuous casting production automation process. The position tracking accuracy of the head and tail blanks will not only affect the position of the high and low pressure automatic switching point of each tension leveler, the position of the light pressing control point of each pinch roller, but also affect the position of the dummy bar's automatic detachment control point, and The positions of the control points for automatic head and tail cutting of the slab. If the tracking and detection of the position of th...

Problems solved by technology

This invention has a redundant effect on the failure of a single encoder failure, but still does not reliably solve the problem of large cumulative errors in the long-distance head-to-tail billet tracking process under the encoder detection method of the tension leveler
