Abstract

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℃.
