Description
Technical Field
The utility model relates to a high temperature resistant, leak protection lose long-life oxygen rifle shower nozzle.
Background
The oxygen lance nozzle is used as a key spare part in converter steelmaking, and is responsible for converting high-purity oxygen into supersonic jet flow to enter molten steel, providing dynamic and thermodynamic conditions required by steelmaking production, and smelting the molten steel into molten steel. The oxygen lance not only bears the strong thermal radiation of a reaction zone in the converter but also bears the strong impact action of high-temperature steel slag in the blowing process, and can contact with molten iron when being improperly controlled, so that the working condition is extremely bad. Once the oxygen lance nozzle is caused to be tempered and burn through the inner pipe of the nozzle, cooling water of the oxygen lance flows into the converter, so that the explosion accident of molten liquid molten steel in the converter is easily caused, and great potential safety hazards exist.
The design parameters of the oxygen lance nozzle directly influence the blowing effect of converter steelmaking, and the service life of the oxygen lance can reflect the stability of the production operation of the converter, the yield and the quality of the steelmaking and the safety of the production. At present, most oxygen lance nozzles of various production units adopt 20 steel seamless pipes as inner pipes, and in the actual production process, due to the cooling effect of cooling water, faster production rhythm and unstable conditions of steel scraps and molten iron, tempering is easy to occur, so that the inner pipes of the oxygen lances are burnt through, oxygen lance corrosion leakage occurs, and great potential safety hazards are brought to converter production personnel and equipment.
Therefore, the problem to be solved is to prevent the inner pipe of the oxygen lance nozzle from burning through in the production process of the converter.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a long-life oxygen lance nozzle which is high temperature resistant and corrosion resistant and solves the problems in the prior art.
The technical scheme adopted for achieving the purpose is that the high-temperature-resistant and corrosion-resistant long-service-life oxygen lance nozzle comprises an outer pipe, a middle pipe is arranged in the outer pipe, a conical disc is arranged in the middle pipe, one end of the conical disc is connected with a 300-series stainless steel industrial seamless pipe, and an oxygen blowing hole communicated with the 300-series stainless steel industrial seamless pipe is arranged in the conical disc.
Furthermore, one end of the oxygen blowing hole is communicated with the 300-series stainless steel industrial seamless pipe, and the other end of the oxygen blowing hole sequentially penetrates through the middle pipe and the bottom end of the spray head to be communicated with an oxygen supply pipeline.

Detailed Description
The present invention will be further described with reference to the following embodiments and the accompanying drawings.
As shown in figure 1, the high-temperature-resistant and corrosion-resistant long-life oxygen lance nozzle comprises an outer pipe 5, a middle pipe 4 is arranged in the outer pipe 5, a conical disc 3 is arranged in the middle pipe 4, one end of the conical disc 3 is connected with a 300-series stainless steel industrial seamless pipe 2, and an oxygen blowing hole 1 communicated with the 300-series stainless steel industrial seamless pipe 2 is arranged in the conical disc 3.
One end of the oxygen blowing hole 1 is communicated with a 300-series stainless steel industrial seamless pipe 2, and the other end of the oxygen blowing hole 1 sequentially penetrates through a middle pipe 4 and the bottom end 6 of the spray head to be communicated with an oxygen supply pipeline.
The utility model adopts 300 series stainless steel industrial seamless pipe as the inner pipe of the oxygen lance nozzle; the oxygen gun cooling water passes through the outer pipe and the middle pipe, the middle pipe and the inner pipe, and oxygen passes through the inner pipe.
Furthermore, in the production process, when the tempering occurs, the high-temperature flame can not burn through the inner pipe again to cause accidents.
The utility model discloses in, the shower nozzle bottom is passed through welded fastening with the one end of outer tube and is connected, conical disk 3 and 300 adopt welded fastening between the seamless pipe of stainless steel industry 2, have seted up the seal groove on 300 the seamless pipe's of stainless steel industry lateral wall, and the sealing member is installed to the seal groove fit-in, and oxygen-blowing hole 1 is the alpha angle with conical disk 3's axis. The utility model discloses when concrete implementation, 300 are seamless pipe of stainless steel industry can prevent the problem of tempering and burn through the inner tube at the steelmaking in-process, can reduce the intensity of labour of the rifle operation of trading and the running cost of equipment, stop the potential safety hazard.
