Abstract: In a method of making chrome steel in an electric arc furnace, a charge of chrome-bearing molten metal in the furnace is decarburized by blowing into the charge a jet of pure oxygen and water vapor through a double lance consisting of two concentric tubes and extending into the furnace through a wall or the roof of the furnace, the end of the lance being submerged in the charge and surrounded by a medium which protects it against high temperature wear.
