<p>PURPOSE:To provide a producing method of a stainless steel, by which the production is easily executed without need to provide two furnaces of a smelting reduction furnace and a decarburizing furnace and the recovery of chromium and desulfurization are effectively executed. CONSTITUTION:In a method to recover chromium into molten steel by reducing the chromium oxide in slag with carbon in the molten steel or carbon in a carbon-containing material by bringing recycled chromium oxide-containing slag into contact with the molten steel before blowing for roughly decarburizing and temp.-raising or during the blowing, the heating by plasma-arc is executed before the blowing or after the blowing.</p> |
