摘要：
A number of metallurgical plants employ ladle stirring with argon at the end of oxygen blowing during the melting process of corrosion-resisting steels [1, 2]. At the same time, the scarcity and relatively high cost of argon, its low pressure in a shop air pipeline restrain most plants from using argon for corrosion-resisting steel production. Compressed air was used instead of argon to intensify the process of decarbonizing when chromium-nickel stainless steels were made with a 40-ton electric arc furnace at the Kuznetsk Metallurgical Plant.
