Technical Study on Ultra-low Sulfur Steel Production in Ansteel

摘要：

Based on the fact of long period deep desulfurization treatment in LF, the relationships among top slag constituent in LF,molten steel constituent, stirring ability of blowing argon, molten steel temperature and desulphurization rate were analyzed. Through the experiments, the parameters about treatment technology of top slag in LF, the Als content in molten steel, slag charge match,molten steel temperature and the argon flow for stirring have been optimized. The desulphurization treatment period in LF can be shortened by 5～8 minutes. The target sulfur content in molten steel can be controlled below 30 ppm within one LF treatment period which is only 36 minutes. The LF treatment period of ultra-low sulfur steel can primarily match with the continuous casting period,multi-heat continuous casting can be ensured.
