Zusammenfassung:The invention particularly relates to a refining method applied to aluminum-containing steel production, which is characterized in that molten steel is refined in an LF (ladle furnace) smelting process by adopting a'five-determination 'method, namely argon flow range in a certain stage, power distribution gear in a second-determination stage, power transmission time in a third-determination stage, deoxidizer amount in a fourth-determination stage, calcium wire amount in a five-determination stage and wire feeding speed. The refining method for aluminum-containing steel production is easy to operate, high in universality and suitable for operation of all aluminum-containing steel in the refining furnace process, and molten steel is smelted mainly through the refining method of'five-fixed 'of the refining furnace; according to the method, the deoxidation effect and the final temperature in the refining process can be stably controlled, the stability of the content of TFe + MnO in refining final slag and the sta
