Abstract

The purpose of the present invention is to provide a ladle surface fault diagnosis method and equipment. The present invention overcomes the deficiencies of the prior art and improves the automatic detection accuracy of ladle surface faults, especially for improving the detection rate of minor faults, while ensuring the detection of ladle surface faults efficiency. The present invention does not use defect data as in the prior art. The present invention uses the temperature trend curve obtained by fitting to calculate the normal value interval of the temperature, and judges whether the ladle is normal through the interval range, so as to avoid the problem of unbalanced positive and negative samples.

Description

technical field [0001] The invention relates to a ladle surface fault diagnosis method and equipment. Background technique [0002] Steel ladle generally refers to molten steel ladle, which is used in steelmaking plants and foundries to receive molten steel and perform pouring operations before open hearth furnaces, electric furnaces or converters. During the operation of the ladle, due to long-term contact with high-temperature molten steel and slag, the service life of the ladle lining will be shortened. According to experience, ladle slag surface (ladle wall), trunnion position and ladle bottom position are prone to failure. If these three failures occur, the safety performance of the ladle will be seriously affected, and in severe cases, molten steel splashing and ladle rupture will be caused. Therefore, real-time monitoring of the surface quality of the ladle is of great significance. At present, the commonly used detection method is to use a temperature measuring gun...
