Efficient converter protection method for predicting converter final slag viscosity model

[0049] like Figure 1-Figure 3 As shown, a high-efficiency furnace protection method for predicting the final slag viscosity model of the converter in this embodiment is carried out according to the following steps. The data acquisition module 11 of the prediction model collects the data information of the steel plant 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 is output by the output module 41 to obtain a slag splashing scheme.

[0050] The data acquisition 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 the composition and temperature of molten iron, the amount of metal loaded and the amount of slagging auxiliary materials added. The auxiliary materials used...

[0085] Using the above-mentioned high-efficiency furnace protection method for predicting the final slag viscosity model of the converter, a successful test was carried out in the Maanshan Iron and Steel Co.

[0086] S1, first exchange data through the data acquisition module 11 and the secondary system of the steel plant, and collect information including molten iron composition, temperature, metal loading and slag making auxiliary material addition, as shown in Table 3 below, and transmit the data in signal form to next level processing;

[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, obtains the final slag viscosity of the converter, and classifies and processes it through the judgment processing module 31 to give the furnace Whether it is necessary to upgra...
