Embodiment Construction

[0034] The present invention will be further described below in conjunction with the examples, but the present invention is not limited.

[0035] like figure 1 As shown, a method for logically judging bonded breakout based on space-sequential features of the present invention includes the following steps:

[0036] 1) Search for hot and cold areas of bonded breakout

[0037] (1) According to the abnormal bonding area and on-site inspection results, establish a sample database of casting billet bonding in the mold;

[0038](2) Based on the continuous casting mold breakout visualization monitoring system, the abnormal bonding area in the mold is visualized, and the thermal image is as follows figure 2 shown;

[0039] (3) Search for hot and cold areas of bonded breakout;

[0040] 2) Obtain the space-sequential features of the hot area of ​​the bond breakout

[0041] (1) Obtain the characteristics of the hot zone area, and determine the maximum value S of the hot zone area of...

Abstract

The invention relates to a bonding breakout logical judgment method based on space-time sequence characteristics in the field of ferrous metallurgy, which is characterized by comprising the following steps of: searching a hot area and a cold area of bonding breakout; acquiring space-time sequence characteristics of the hot area; acquiring space-time sequence characteristics of the cold area; and judging true and false bonding breakout and the like. Based on a visual monitoring system forcontinuous casting crystallizer breakout, the true and false bonding breakout is judged by utilizing the characteristics of the hot area and the cold area of the bonding breakout and adopting a logical judgment method, and an accurate and rapid judgment method is provided for the detection of the continuous casting breakout.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy continuous casting, and relates to a logical judgment method for bonded breakout based on space-time sequence characteristics. Background technique [0002] As a major catastrophic accident in continuous casting production, breakout not only brings great disturbance to the normal production order, but also destroys the equipment of the continuous casting machine and causes huge economic losses. In order to reduce the interference of breakout accidents on continuous casting production, the main influencing factors of breakout have received extensive attention from metallurgical workers, and the method of breakout forecasting is also under constant optimization and research. It is generally believed that the billet bond breakout is formed near the meniscus, and the billet shell tearing caused by poor mold lubrication and excessive friction is the direct cause of billet sticking, wh...
