A furnace oxygen supply device is provided to improve the decarboxylation performance of a lance nozzle, reduce the oxygen blowing time, and increase the yield of hot metal. A furnace oxygen supply device includes a lance body disposed at an upper side of a converter, a nozzle body(120) connected to an end of the lance body, an air supply(130) connected to the nozzle body for jetting oxygen into the converter via the nozzle body, a cooling media supply(140) connected to the nozzle body for cooling the nozzle body by the flow of cooling media, and a cooling unit(150) coupled in the nozzle body and receiving working fluid inside. The cooling unit cools the nozzle body by the circulation of the working fluid through the evaporation and condensation due to capillary phenomena in response to temperature gradients. |
