The paper considers that the application in metallurgical enterprises-s mixing argon bath at the end of oxygen blowing in the smelting of corrosion-resistant steel has found wide application [1, 2]. However, the deficit-ness and the relatively high cost of argon, low pressure in his shop on line constrain most plants use argon at you-melting corrosion resistant steels. The article suggests that in-intensification of decarburization in the smelting of corrosion-resistant chromium-nickel steels in the 40-ton electric arc furnace use compressed air instead of argon.
