摘要

摘要: 基于鋼水爐外脫磷工藝, 在實驗室對鋼水爐外脫磷劑的選用開展實驗研究.首先確定轉爐鋼水在管式爐中脫磷時初始磷含量和脫磷劑加入量, 然后分別對不同成分和配比的Ca O系和Ba O系脫磷劑進行研究.實驗結果表明, 最佳Ca O系脫磷劑的配比為w (Ca O) ∶w (Ca F₂) ∶w (Fe O) = (65⁷0) ∶ (15²0) ∶ (10²0) , 最佳含Fe O的Ba O系脫磷劑的配比為w (Ba O) ∶w (Ca O) ∶w (Ca F₂) ∶w (Fe O) = (10²0) ∶ (55⁶5) ∶15∶10, 不含Fe O的Ba O系脫磷劑的最佳配比為w (Ba O) ∶w (Ca O) ∶■

Abstract: Based on the deep dephosphorization process of molten steel out of converter, the various dephosphorization agents for secondary dephosphorization were investigated by laboratory scale experiments.The initial phosphorus content in steel and the amount of dephosphorizing agent added into the tube furnace were firstly determined.And then, the compositions of the Ca O-based and Ba O-based dephosphorization agent were investigated, respectively.The results shows that the best ratio of Ca O-based dephosphorizing agent is w (Ca O) ∶w (Ca F₂) ∶w (Fe O) = (65-70) ∶ (15-20) ∶ (10-20) , the best ratio of Ba O-based dephosphorizing agent with Fe O is w (Ba O) ∶w (Ca O) ∶w (Ca F₂) ∶w (Fe O) = (10-20) ∶ (55-65) ∶15∶10 and the best ratio of Ba O-based dephosphorizing agent without Fe O is w (Ba O) ∶w (Ca O) ∶w (Ca F₂) = (30-40) ∶ (55-65) ∶ (15-20) .
