[0048] Example 1
[0049] Such as Figure 1-Figure 3 As shown, an efficient furnace protection method for predicting the final slag viscosity model of the converter in this embodiment is performed according to the following steps. The data acquisition module 11 of the prediction model collects the data information of the steel mill feeding system in real time and transmits it to the calculation processing module 21. The information processed by the calculation processing module 21 is classified and processed by the judgment processing module 31 to obtain different output results, and the output module 41 outputs to obtain the slag splash solution.
[0050] The data collection module 11 of this embodiment is used to exchange information and data with the secondary feeding system of the steel plant. The collected information includes information on the composition and temperature of the molten iron, the amount of metal and the amount of slagging auxiliary materials. The auxiliary mate...

[0084] Example 2
[0085] Using the above-mentioned high-efficiency furnace protection method for predicting the final slag viscosity model of the converter, the top and bottom combined blowing converter of Maanshan Iron and Steel Co., Ltd. was successfully tested to control the final slag viscosity of the converter to achieve the purpose of efficient slag splashing. The steps are:
[0086] S1. First carry out data exchange through the data acquisition module 11 and the secondary system of the steel plant, collect information including the composition of molten iron, temperature, metal loading and slagging auxiliary material addition, as shown in Table 3 below, and transmit the data to Next level processing
[0087] Table 3 Data collected by the secondary system
[0088]
[0089] S2. The calculation processing module 21 receives the upper-level transmission data, performs processing, selects and searches in the database module 220 by establishing a mathematical model, and obtains the ...
