Advanced technological solutions for developing a technology of steel production from the steel scrap with excessive copper content

Abstract

It was shown, that it is possible to raise effectiveness of the sulfide treatment with the help of special organization of the process: intensive saturation of the iron melt with sulfur in the process of its blowing with powders based on sulfur and sulfurcontaining compounds; the creation of favorable conditions for sulfide inclusions formations and following extension of them, as well as further thorough separation of sulfide and iron phases. Applying to modified filtration technique to separate these phases allows considerably increase the total copper removal from metal after sulfidyzing treatment and decrease contamination by sulfides. The worked out and tried in the investigations technical solutions make promising the realization of copper removal from iron-carbon melts at industrial conditions
