SUMMARY:Development of ladle furnace automation system
DESCRIPTION:In the steelmaking process, the input of ferroalloy, especially Mn, causes a lot of heat loss. In this situation, the importance of the ladle furnace is gradually increasing as the production of high-grade steels containing a lot of alloys increases. However, due to the characteristics of LF operation, it is difficult to standardize operation, so automation is being developed later than other secondary refining facilities such as RH. However, with the recent development of machine learning techniques, it is possible to develop models with high accuracy, and it is also easy to connect the calculation results of these models with systems such as PLCs. As a result, demand for automation system development is increasing in LF as well.
Our company developed a high-accuracy model for temperature prediction and completed a field test, and also developed a linear programming-based model for calculating the ferroalloy input. Based on the operator's operation performance, the pattern model according to the situation was configured as a rule-based system, and the automation system was developed by combining the previously developed temperature and ferroalloy model. As a result of applying an automated system that minimizes operator intervention to the operation, it was confirmed that more standardized and less variance operations were possible.
