A newly developed bottom gas blowing method consisted of bottom nozzle with double or triple annular tubes was presented to improve the flexibility of the bottom gas flow rate and the bottom blowing stability. Hydrocarbon blowing through the inner tube of the bottom nozzle realized stable stirring without over cooling of the nozzle. By using bottom gas blowing method mentioned above, iron oxidation was suppressed in the last stage of the blowing and (T.Fe) content which meant iron content existed as iron oxide in the slag was decreased.
