Investigation on the Ultra-Low Nitrogen Steel Smelting Techniques

摘要：

　　In this paper,the relative factors which influence denitrogenation during smelting process of IF steel were systemically analyzed.The results indicated that nitrogen concentration in the molten steel decrease with sulfur decreasing,slag amount increasing,re-blowing time shortened and deoxidization.The carbon content at ending point controlled within 0.06% ~0.07% can guarantee lower nitrogen content in tapped molten steel.
