  • Patent number: 4652306
    Abstract: Molten steel is tapped from a converter into a refining ladle, and an ore such as Nb.sub.2 O.sub.3 ore is charged into the molten steel. Then, the interior of the refining ladle is held in an inert gas atmosphere. A reducing agent such as an Al reducing agent is charged into the molten steel. Electrodes are dipped in slag on the molten steel to form an arc therebetween so as to heat the molten steel with an arc. The ore is reduced by the reducing agent, so that a metallic component of the ore is added to the molten steel. On the other hand, carbon electrodes each having a gas supply port at its lower end can be used to inject an ore powder or particles from the injection ports to the arc between the electrodes and molten steel. The ore is reduced by electrode carbon with arc heat, so that a desired component is added to the molten steel.

  • Patent number: 4551174
    Abstract: Nondeoxidized molten steel is removed from a steel converter and poured into a ladle. Carbon electrodes are submerged in a slag layer on the molten steel and are separated by a predetermined distance from the molten steel. The electrodes are energized to generate arcs with the molten steel. Argon gas is blown into the molten steel through a lance submerged in the molten steel to stir the molten steel with the gas. The molten steel is arc-heated and at the same time stirred. Carbon in the molten steel reacts with residual unstable oxygen in the steel to deoxidize the molten steel. The molten steel is also decarburized, thereby preventing an increase in carbon content of the molten steel in the arc process.
