摘要: 使用Al₂O₃坩堝在真空感應爐內測定了1600℃時氮在含C還原渣和鋼液之間的總傳質系數β_o.研究表明，β_o與氣相中氮分壓P_N₂的大小有關，隨著P_N₂的增加β_o增大.由物料平衡計算得出，在本實驗條件下，β_o為3.7×10^-4 cm/S.

Abstract: The total transport coefficients of nitrogen from reducing slag containing carbon into liquid steel in Al₂O₃ crucible at 1600℃ have been measured. The result shows that β has been related to the panial pressure of nitrogen in gas phase P_N₂, β increases with the increase of P_N₂ The calculated results of mass balance was shown that under this experimental condition β₀ =3.7×10^-4 cm/s.
