Abstract

Process for producing steel with ultra-low carbon content comprises receiving and refining the melt. The refining of melt is provided in a converter with a bottom stay, by first purging is performed with a protective oxygen (natural) gas to obtain a carbon content of 0.03-0.04% in the melt, and then continue to purge with the argon-oxygen mixture with an oxygen content in the blast 10- 15% to obtain a carbon content in the melt 0.007-0.009% and then to purge with pure argon until the carbon content in the melt is not more than 0.002%.
