摘　　要：为了更好地改善硅钢的电磁性能,需要尽可能地降低钛含量。磷元素可以显著改善钢的机械性能,部分硅钢品种通常磷含量较高。本文结合工业化的生产,研究了炼钢工艺对硅钢钛含量控制的影响,通过采用优质磷铁,控制RH精炼初始游离氧含量,以及优化磷铁加入方式等措施,可以将含磷硅钢的钛含量有效降低至10×10-6以下。Titanium is an impurity element for steel. In order to improve the magnetic properties of silicon steel, it is necessary to remove the titanium. Phosphorus can obvious improve the mechanical properties of electrial steel, and the middle and low grade electrical steel sheet always have high phosphorus content. Effects of phosphorus content and steelmaking process on titanium content were discussed in present work. By adopting high quality ferrous-phosphorus and addition method, and controlling the free oxygen content at the beginning of RH refining, the titanium content of the electrical steel containing phosphorus can be keep under 10×10-6.
