Early warning judgment method and early warning judgment device for bonding bleed-out

Abstract

The invention discloses an early warning judgment method and an early warning judgment device for bonding bleed-out, a single row of temperature measuring points are arranged on a crystallizer along the width direction of a casting section, and the method comprises the following steps: acquiring temperature values of the temperature measuring points on a time sequence to form a two-dimensional temperature matrix; carrying out mode processing on the temperature values of the two-dimensional temperature matrix to form a mode matrix, wherein the mode processing refers to converting the temperature value of the temperature rising starting point into a, converting the highest temperature into b and converting other temperature values into c for the temperature value of each temperature measuring point if the temperature is in a rising-to-falling mode; for the non-rising-to-falling mode, converting the temperature into a; and identifying data of the mode matrix to obtain an equivalent feature contour, judging whether a triangular early warning block is formed or not, and taking whether the triangular early warning block is expanded in the transverse direction and / or the longitudinal direction or not as a judgment basis for bonding or not. According to the invention, the defect that early warning depends on multiple rows of thermocouples is solved, the maintenance cost is reduced, andthe phenomena of missing report and false report caused by thermocouple abnormality are reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgical production, in particular to an early warning judgment method and an early warning judgment device for bonded breakouts. Background technique [0002] In metallurgical production, steel breakout is a catastrophic production accident with high frequency and high destructiveness, and bonded steel breakout is the most frequent type of accident among all steel breakout accidents. Therefore, when bonding defects occur in production, through timely Identifying the occurrence of bonding and taking corresponding measures is an important part of preventing steel breakout accidents. [0003] At present, there are many methods of bonding judgment, such as logical judgment method, neural network method, image neural network method, etc., but still have not solved the problem of bonded breakout in the metallurgical industry. The main defects of these methods are: [0004] Logical judgment method: By stu...
