[0050] Next, in connection with the accompanying drawings, the present invention is further elaborated in conjunction with the accompanying drawings.
[0051] like figure 1 The flow chart shown is shown in the crystallizer leakage steel forecasting method. First, extract the visualization characteristics of the crystallizer copper temperature rate and the pretreatment of it, the structure is obtained, and the six-dimensional special vector; secondly, the logic regression model is adjusted and trained; finally, through the training good logic regression model Classify and drain steel forecasts for feature vectors.
[0052] First step, crystallizer copper plate temperature rate visualization and abnormal regional feature extraction
[0053] (1) such as figure 2 The displayed copper plate and its thermocouple are shown in the crystallizer. The crystallizer is combined by four copper plates, with a total height of 900 mm, and the effective height of 800 mm is 800 mm. In the crystalliz...
