Effects of Temperature and Sulfur Content on Kinetics of Nitrogen Removal of Liquid Steel

Metallurgy School, UST Beijing, Beijing 100083, China

摘要: 在LECO436氧氮分析儀上研究了1600~2813℃溫度范圍內鋼液脫氮動力學。結果表明:溫度低時,脫氮受液相邊界層傳質及界面化學反應混合控制,溫度高時,脫氮受液相邊界層傳質過程控制。在2250℃以下,溫度對k₁'的影響服從Arrhenius公式。硫對脫氮的阻礙作用隨著溫度的升高而降低,在溫度2250℃以上,硫的表面活性作用消失。

Abstract: The kinetics of denitrogenization of liquid steel was studied in LEC0436 under 1 600~2 813℃. The results showed that when the temperature is lowen nitrogen removal is controlled by both nitrogen transferring in liquid transfer layer and the chemical reaction at the liquid-gas interfacei and when the temperature is higher, it is only controlled by nitrogen transferring in liquid transfer layer. Under 2 250℃, the effect of temperature on k₁' followed Arrhenius formula. The resistance of sulfur on nitrogen removal decreases as the temperature rises, and disappeares at temperature 2250℃.
