Abstract
As bottom-blowing O2–CaO converter steelmaking process enables rapid slag formation, efficient phosphorus removal, and improved steel quality. It has significant strategic significance for the greening and high-quality development of the iron and steel industry. In this study, we collected field actual smelting data, established a mass and energy model, and developed a bottom-blowing O2–CaO control model with Visual Studio.NET 2019 (VS2019) as the development tool. The application results indicated that bottom-blowing lime powder flow accuracy is ± 50 kg/min, time accuracy is ± 30 s, and the degree of automation reaches more than 90%. Real-time monitoring allows for dynamic adjustment of the converter's O2–CaO bottom-blowing and accurate control, improving steelmaking production efficiency.
