PROCESS FOR REFINING HIGH-CHROMIUM STEELS Abstract of the Disclosure: A process for refining high-Cr steel, e.g. 13%Cr steel and 18%Cr steel, is disclosed. The process comprises preparing molten iron in a top-and-bottom blowing converter, heating the molten iron to a predetermined temperature, effect- ing the decarburization of the thus prepared molten iron by blowing oxygen gas through a top lance against the surface of the molten iron to provide a molten steel while, as bottom- blown gas, initially introducing an oxygen-containing gas into the molten steel then changing to an inert gas when the carbon content of said molten steel is reduced to a predetermined level so as to suppress the oxidation of chromium, and tapping the resulting molten steel out of the converter after adjusting the steel composition.
