<p>A manipulator of an oxygen blowing apparatus is provided to allow the user to use an oxygen lance within a small space by regulating the insertion angle of the oxygen lance into an electric furnace by bending the oxygen lance to regulate the insertion of the oxygen lance into the electric furnace. A manipulator of an oxygen blowing apparatus comprises a case(10) having a front hole(8a) and a rear surface(8b), an oxygen lance(4) which is drawn out from the rear hole to supply oxygen to the electric furnace, a bending unit(20) which applies a bending force in a bending roller so that the oxygen lance is bent on the front end of the case, a driving unit(80) outputting the driving force and driving the oxygen lance with the outputted driving force, a pinch unit(160) which pinches or releases the oxygen lance while applying or cutting-off the outputted pinch driving force, a tilt control unit which regulates the inclination angle of the case while outputting a tilt control force upward or downward on the rear upper side of the case, and a guide unit which guides entry or exit of the oxygen lance to the case.</p> |
