<p>A reduced chromium-ore bearing powder used for producting of a chromium-containing steel in a converter, is produced by a reduction of chromium-ore powder having a particle-diameter of 3 mm or less by a carbonaceous reducing agent having a particle diameter of 3 mm or less in an inert-gas atmosphere, while the chronium-ore powder and carbonaceous reducing agent are stirred and mixed with each other in the reaction chamber (5). The reduced chromium-ore powder has 3 mm or less of particle diameter. Acid-soluble chromium is in an amount of 85 % or more of the total chromium, and acid-soluble iron is in an amount of 95 % or more of the total iron.</p> |
