Abstract
The invention relates to the steel production in oxygen-blown vessels. A method for metal purification involves melt blowing with oxygen gas, containing nitrogen admixture, in quantity, determined by passing of reaction of melt decarbonization. During scavenge period of corresponding region of supercritical carbon content in metal carbonaceous material, discharge intensity of which is determined from carbon content in metal and carbonaceous material, is introduced into the melt.
