Rotating oxygen lance of converter

The utility model provides a rotating oxygen lance of a converter and relates to a mechanical auxiliary part. The rotating oxygen lance comprises a connector, a gas outlet, an oxygen port and an intake tube; the connector is a hollow cylinder and is connected with a tube bundle; the oxygen port is arranged in the middle position of the connector; the intake tube is arranged on the tube bundle; a valve is arranged on the intake tube; the tube bundle is connected with a rotating box; the intake tube is connected with the rotating box; a rotor is arranged inside the rotating box and the rotor is connected with the rotating box by use of a bearing; a blade is arranged on the rotor; the gas outlet is formed in the sidewall of the rotating box; a round cap is arranged at the bottom of the rotor and fixed on the rotor by welding. The intake tube is used for blowing the oxygen into the rotating box; the oxygen pushes the blade to drive the rotor to move; the rotor drives the round cap to rotate, so that the oxygen is ejected via the oxygen port; as the round cap is rotary, the oxygen is sprayed in a plurality of directions; through the process, the steel can be oxidized more uniformly, the toughness of the steel can be higher, the working efficiency can be greatly improved and the resources can be saved.
