ABSTRACT

Optimizing refining processes is crucial for the advancement of steel mills. This study provides a comprehensive overview of historical LF methods, examining their strengths and weaknesses. By comparing and analyzing various refining processes, it highlights the advantages of the LF refining process, including its low equipment investment cost, suitability for smelting multiple steel grades, and compatibility with other refining methods. Whether establishing new lines or upgrading existing ones, the LF process offers high cost-effectiveness. Strategies such as phased aluminum calcium line feeding and the use of new refined slag to replace fluorite have been successfully employed to enhance the LF refining process, yielding significant results in practical applications. This study serves as a technical reference and offers development insights for refining process optimization in steel plants.
