摘　　要：通过试验研究了钢液在脱氧过程中氧含量和夹杂物尺寸的变化规律,分析了夹杂物与组织的关系。结果表明,钛脱氧后氧含量基本稳定在0.001%(质量分数)左右,夹杂物尺寸在钛脱氧4 min后达到最小值,平均尺寸为1.27μm,此时钢的凝固组织为均匀分布的针状铁素体。The change pattern of oxygen content and inclusions in liquid steel during deoxidizing was in- vestigated through experiments, and the relationship between inclusions and microstructures was also analyzed. The results show that the oxygen content stabilizes around 0. 001% （mass fraction） after de- oxidizing, and the inclusion size reaches the average minimum value of 1.27 OLin after deoxidizing for 4 minutes when aeicular ferrite distributes uniformly in the steel.
