METHOD OF PRODUCING Russian patent published in 1996 - IPC

Abstract RU 2069232 C1

FIELD: ferrous metallurgy. SUBSTANCE: when producing balanced steel microalloyed with vanadium and nitrogen in converter by a method involving blowing metal smelt with oxygen, heating metal, prior to be tapped into ladle, to a temperature by 5- 20 C higher than prescribed temperature, introducing deoxidizing agents, alloying additives, and vanadium slag to metal smelt, and blowing metal in ladle with inert gas, into the ladle, simultaneously with introducing slag nitrogen-containing additives begin to be added and their addition stops when metal tap is finished. EFFECT: facilitated nitrogen content control.
