Abstract

Abstract—The formation and ascent of gas bubbles when disperse magnesium is injected into hot metal in an argon jet are analyzed. The thermodynamic probability that magnesium will react with oxygen, nitrogen, and hydrogen during desulfurization of the hot metal is established. Industrial experiments provide information regarding the removal of harmful impurities from hot metal on desulfurization by the injection of disperse magnesium in a gas jet.
