IF steel refining process alloying method

The invention particularly relates to an IF steel refining process alloying method, which belongs to the technical field of steel refining, and is characterized in that a titanium-iron alloy is added for multiple times, a part of the titanium-iron alloy is added for the first time, a high-titanium-concentration area is formed around the titanium-iron alloy, and reacted with aluminum oxide inclusions in steel to form a part of aluminum-titanium composite oxide, however, the removal capacity of the cluster-shaped aluminum oxide is very high, and after the ferrotitanium alloy is added in the later period, the aluminum oxide inclusions in the steel are reduced, and the reactions are correspondingly reduced, so that the number of the generated aluminum-titanium composite inclusions is reduced, and the yield of the ferrotitanium alloy is increased to 85-95% from 70-80%. 本发明特别涉及一种IF钢精炼过程合金化方法，属于钢铁精炼技术领域，通过将钛铁合金分多次加入，第一次加入部分钛铁合金，钛铁合金周围形成了高钛浓度区域，与钢中氧化铝夹杂物反应，形成一部分铝钛复合氧化物，但簇状氧化铝去除能力很强，后期加入钛铁合金后，由于钢中氧化铝夹杂物减少，上述反应相应减少，因此生
