Description

Technical Field

[0001] The present application relates to the technical field of converter tuyere tube installation, and in particular to a converter tuyere tube installation tool. Background Art

[0002] The tuyere is a key component of the converter, responsible for delivering air (or other blowing gas) into the molten pool within the converter to participate in the oxidation reaction. The tuyere plays a crucial role in this process, ensuring the uniform distribution and effective utilization of the blowing gas, which in turn impacts converter production efficiency and product quality.

[0003] To ensure the long-term stable operation of the converter tuyere tubes, they require regular maintenance and upkeep. This includes clearing slag from the tubes, inspecting them for wear, and replacing damaged ones. Furthermore, careful control of parameters such as temperature and pressure during the blowing process is crucial to minimize erosion and wear on the tubes.

[0004] After each maintenance operation, the tuyere tubes need to be installed on the converter tuyere base. The traditional installation method involves manually rotating the tuyere tubes to secure them to the base. However, due to the large number of tuyere tubes, this method is labor-intensive.

[0033] The above description is merely an optional embodiment of the present application and is not intended to limit the present application.

[0034] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0035] Example 1:

[0036] See also Figure 1 and Figure 2 A converter tuyere tube installation tool, the converter tuyere tube installation tool comprising:

[0037] Electric drill 1;

[0038] A connecting rod having a square cross section at one end and a circular cross section at the other end to form a square column segment and a cylindrical segment;

[0039] A four-jaw chuck 2 is provided with a sleeve 3, and a square hole and a round hole matching the square column segment and the cylindrical segment are provided in the sleeve 3;

[0040] One end of the connecting rod is installed in the chuck of the electric drill 1, and the other end is embedded in the sleeve 3, so that when the electric drill 1 is operated, the connecting rod is driven to follow its synchronous movement, thereby driving the sleeve 3 and the four-jaw chuck 2 to rotate.

[0041] Specifically, during use, the jaws of the four-jaw chuck 2 are inserted into the tuyere tube 5, and the position of the jaws is adjusted so that they are firmly fixed to the upper end of the tuyere tube 5. After installing one end of the square column section of the connecting rod (not shown) into the chuck of the electric drill 1, the entire connecting rod is inserted into the sleeve 3. The electric drill 1 is then started, and the torque of the electric drill 1 is transmitted through the connecting rod to the sleeve 3 and the four-jaw chuck 2, thereby driving the sleeve 3 and the four-jaw chuck 2 to rotate. The four-jaw chuck 2 then drives the tuyere tube 5 to rotate, allowing it to be installed on the tuyere seat.

[0042] In this embodiment, the installation of the air eye tube 5 is achieved through the cooperation of the electric drill 1, the connecting rod, the sleeve 3 and the four-jaw chuck 2. The electric drill is used instead of the manual drive method, which reduces the labor intensity and improves the installation efficiency.

[0043] It should be noted that the four-jaw chuck 2 is an existing structure and will not be described in detail here.

[0044] Example 2:

[0045] See also Figures 2 to 5 Based on the first embodiment, optionally, the sleeve 3 is fixed to the four-jaw chuck 2 through a steel pad 4.

[0046] Specifically, one end of the steel pad 4 is welded to the sleeve 3, and the other end is welded to the end of the four-jaw chuck 2 away from the jaws. In this way, the sleeve 3 and the four-jaw chuck 2 are fixed, so that the torque of the sleeve 3 can be transmitted to the four-jaw chuck 2.

[0047] Optionally, the inner diameter of the end of the sleeve 3 close to the steel pad 4 is 14 mm.

[0048] Specifically, see Figure 5 Since the connecting rod has a cylindrical section, a circular hole matching the cylindrical section of the connecting rod is opened inside the end of the sleeve 3 close to the steel pad 4 to facilitate the fit of the two and thus facilitate the transmission of torque. The diameter of the circular hole is 7 mm.

[0049] In this embodiment, the inner diameter of the end of the sleeve 3 close to the steel pad 4 is selected to be 14 mm, which facilitates the opening of the circular hole while ensuring that the sleeve 3 has a certain structural strength.

[0050] Optionally, the inner diameter of the end of the sleeve 3 away from the steel pad 4 is 22 mm.

[0051] Specifically, see Figure 5 Since the connecting rod has a square column section, a square hole matching the square column section is opened inside the end of the sleeve 3 away from the steel pad 4 to facilitate the fit of the two and thus facilitate the transmission of torque. The square hole is connected to the aforementioned round hole to facilitate the embedding of the connecting rod.

[0052] Optionally, the diameter of the steel pad 4 is 24 mm.

[0053] Specifically, the diameter of the steel pad 4 should be larger than the inner diameter of the end of the sleeve 3 close to the steel pad 4 to facilitate welding of the sleeve 3, so the diameter is selected to be 24 mm.

[0054] Optionally, the connecting rod and the steel pad 4 are made of Q345 steel.

[0055] Specifically, Q345 steel is a high-strength steel that can withstand significant external forces without deformation or damage. It also has excellent weldability and is less prone to defects such as cracks and pores during welding.

[0056] Optionally, the sleeve 3 is made of stainless steel.

[0057] Specifically, stainless steel is resistant to most chemical media, including acids, alkalis, and salts, and has excellent stability in humid and corrosive environments, extending its service life. Stainless steel has high wear resistance and can maintain its surface integrity and durability under conditions of friction and wear.

[0058] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.

[0059] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
