Study on Control Technology of Slag Composition for Low-Sulfur and Low-Oxygen Steel

摘要：

In order to reduce the content of oxygen and sulfur in steel, and produce low-sulfur and low-oxygen steel, study on slag has been carried out. Refining slag system of CaO-SiCVA^C^ is put forward with the consideration of slag amount from converter, oxidizability of slag and activity of oxygen in molten steel. On this basis, refining slagging system for low-sulfur and low-oxygen steel has been developed combined with the modification of slag from converter and composition control of refining slag in LF treatment process. The results show that oxygen content is not more than 15x10-6, as well as sulfur content is as low as 0.005％ in tube blank steel. And it achieves the production of low-sulfur and lowoxygen steel.
