Description

Technical Field

[0001] This invention relates to the field of medium carbon steel converter steelmaking equipment, and more specifically to a medium carbon steel converter steelmaking equipment and method. Background Technology

[0002] Medium carbon steel converter steelmaking equipment is a converter system and its supporting devices specifically designed for the production of medium carbon steel. Its core lies in achieving high-precision control of composition and temperature through precise control of the smelting process. However, in most existing technologies, the metal raw materials are fed into the converter via a tilting method. This poses a risk that, due to the rapid pouring of the metal raw materials, a large amount of waste material may fall simultaneously during the tilting process, resulting in a lack of stability in the pouring of the metal raw materials. Therefore, this application is proposed to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this invention is to provide a medium carbon steel converter steelmaking equipment and method. The beneficial effect is that, during the medium carbon steel converter steelmaking process, it is easier to improve the stability of the metal raw materials when they are fed into the converter and to prevent the metal raw materials from scattering.

[0004] The objective of this invention is achieved through the following technical solution: a medium carbon steel converter steelmaking equipment, comprising a support base and a tilting frame rotatably connected to the middle of the support base, a converter fixedly connected to the middle of the tilting frame, a transverse sliding seat slidably connected to the rear side of the support base, a storage box slidably connected to the middle of the transverse sliding seat, a right-angle seat slidably connected to the rear side of the storage box, a pusher plate fixedly connected to the front side of the right-angle seat, and a lead screw rotatably connected to the top of the rear side of the support base, the lead screw being drivenly connected to the top lead screw of the transverse sliding seat.

[0005] Both sides of the pusher plate are curved and face forward.

[0006] The lower surface of the pusher plate slides against the inner bottom surface of the storage bin.

[0007] A concave frame is fixedly connected to the right side of the storage box. A sliding frame is slidably connected to the concave frame. Multiple long rods are rotatably connected to the sliding frame. Multiple ring tubes are fixedly connected to the left side of each long rod. Multiple conical plates are evenly fixedly connected to the surface of each ring tube along the circumferential direction. A sprocket is fixedly connected to the right side of each long rod. The multiple sprockets are connected by a transmission chain.

[0008] The bottom of the storage bin has multiple elongated holes.

[0009] A method for producing medium-carbon steel using the aforementioned medium-carbon steel converter equipment includes the following steps:

[0010] S1: Pour the metal raw materials for steelmaking into the storage box, and move the storage box to one side of the converter by the lateral movement of the transverse shifter.

[0011] S2: The converter relies on the two sides of the tilting frame as the rotation center, so that the furnace mouth of the converter is tilted towards the storage box;

[0012] S3: The raw materials located in the storage bin are poured into the converter by pushing the pusher plate;

[0013] S4: Before S3, multiple long rods are inserted into the storage box, and the conical blades on the long rods make circular motions, stirring the metal raw materials in the storage box. Attached Figure Description

Detailed Implementation

[0026] A medium carbon steel converter steelmaking equipment includes a support base 101 and a tilting frame 102 rotatably connected to the middle of the support base 101. A converter 202 is fixedly connected to the middle of the tilting frame 102. A transverse sliding seat 301 is slidably connected to the rear side of the support base 101. A storage box 302 is slidably connected to the middle of the transverse sliding seat 301. A right-angle seat 401 is slidably connected to the rear side of the storage box 302. A pusher plate 402 is fixedly connected to the front side of the right-angle seat 401. A lead screw 103 is rotatably connected to the top of the rear side of the support base 101. The lead screw 103 is connected to the top lead screw of the transverse sliding seat 301 via a transmission connection.

[0027] This section is based on Figure 1-7The working process described in sections 10 and 11 is as follows: During the medium carbon steel converter steelmaking process, in order to improve the stability of the metal raw materials when feeding them into the converter and to prevent the metal raw materials from scattering, the recovered metal scrap is poured into the storage box 302. The output shaft of the first motor is fixedly connected to the right side of the lead screw 103 via a coupling. The first motor is fixedly mounted on the top of the support base 101 by bolts. Driving the first motor causes the lead screw 103 to rotate. When the lead screw 103 rotates, the lead screw drive connected to it... The transverse shifter 301 moves laterally, and the storage box 302, which is slidably connected to the middle of the transverse shifter 301, moves laterally synchronously. The movable end of the first electric push rod is fixedly connected to the top rear side of the transverse shifter 301 via a flange. The fixed end of the first electric push rod is fixedly connected to the top of the transverse shifter 301. When the storage box 302 moves from its front opening to one side of the top of the converter 202, the first electric push rod is driven to move the front opening of the storage box 302 to the furnace opening position of the converter 202. Further, in the vertical... The rear side of the corner seat 401 is fixedly connected to the movable end of a second electric push rod via a flange. The fixed end of the second electric push rod is fixedly connected to the bottom of the storage box 302 via a flange. Driving the second electric push rod causes the right-angle seat 401 located at the movable end to move the push plate 402 within the storage box 302, and pushes the metal raw material in the storage box 302 out through the opening on the front side of the storage box 302 and into the converter 202 at the bottom of the opening of the storage box 302. Compared with the existing technology, which involves turning over the container containing the metal raw material, there is a risk of a large amount of waste material falling simultaneously during the turning process and scattering around the furnace body, which may injure the workers around the furnace body. Therefore, the storage box 302 containing the metal raw material is set horizontally and the internal raw material is pushed out horizontally by the push plate 402. This can control the amount of raw material pushed out and falling into the converter 202, while preventing the falling raw material from scattering around the furnace body and injuring the workers around the furnace body, thus improving the stability of the metal raw material when feeding it into the converter.

[0028] Both sides of the pusher plate 402 are arc-shaped and face forward.

[0029] This section is based on Figure 1-7 The working process described in 10 and 11 is as follows: both sides of the pusher plate 402 are arc-shaped facing forward, and the outer edges of the two arcs are respectively attached to the inner two sides of the storage box 302. When the pusher plate 402 pushes out the metal raw material in the storage box 302 through the opening on the front side of the storage box 302, the metal raw material in the storage box 302 can be pushed out more comprehensively through the arc-shaped parts on both sides.

[0030] The curved design on both sides of the pusher plate 402 naturally guides the material towards the opening on the front side of the storage bin 302, reducing material accumulation in the corners or edges of the bin. The curved shape eliminates right-angle areas, avoiding stagnation zones caused by right-angle obstructions during the pushing process, ensuring smooth material discharge.

[0031] Compared to the traditional method of tipping over containers containing metal materials to discharge them, the pusher plate 402 that can push the material reduces the discharge interruption caused by material accumulation or jamming.

[0032] Furthermore, the storage bin 302 is set horizontally and the internal raw materials are pushed out horizontally by the pusher plate 402, so that the metal scrap can be discharged from the discharge port in a more stable and controllable manner, avoiding the material splashing or scattering caused by inertia during the traditional flipping discharge method.

[0033] The lower surface of the pusher plate 402 slides against the inner bottom surface of the storage box 302.

[0034] This section is based on Figure 1-7 The working process described in 10 and 11 is as follows: the lower surface of the pusher plate 402 slides and adheres to the inner bottom surface of the storage box 302, so that the pusher plate 402 can rub against the inner bottom surface of the storage box 302 when pushing the metal raw material, and can push out the raw material located inside the storage box 302 more comprehensively.

[0035] A concave frame 303 is fixedly connected to the right side of the storage box 302. A sliding frame 501 is slidably connected to the concave frame 303. Multiple long rods 503 are rotatably connected to the sliding frame 501. Multiple ring tubes 504 are fixedly connected to the left side of each long rod 503. Multiple conical plates 505 are evenly fixedly connected to the surface of each ring tube 504 along the circumferential direction. A sprocket is fixedly connected to the right side of each long rod 503. The multiple sprockets are connected by a transmission chain.

[0036] This section is based on Figure 1-11 The working process described is as follows: In order to facilitate the stirring of the metal scrap collected in the storage box 302, the impurities adhering to the surface of the metal scrap in the storage box 302 are removed by stirring, thereby improving the cleanliness of the metal scrap and improving the overall purity of the steel in the subsequent steelmaking process.

[0037] In use, the output shaft of a second motor is fixedly connected to the right side of the rear long rod 503 via a coupling. The second motor is bolted to the rear side of the sliding frame 501. A third electric push rod's movable end is fixedly connected to the bottom of the sliding frame 501 via a flange. The fixed end of the third electric push rod is fixedly connected to the right side of the concave frame 303. Driving the second motor causes the rear long rod 503 to rotate. When one long rod 503 rotates, multiple long rods 503 rotate synchronously via sprockets and a transmission chain, thus affecting the rotation of each long rod. Multiple ring tubes 504 on the long rod 503 and multiple conical blades 505 on each ring tube 504 synchronously move in a circular motion along the corresponding long rod 503 as the central axis. This drives the third electric push rod to make the sliding frame 501 extend the conical blades 505 that are moving in a circular motion into the storage box 302. Thus, the metal scrap located in the storage box 302 is agitated by the multiple conical blades 505 moving in a circular motion. During agitation, the metal scrap collides and rubs with each other, thereby removing the impurities adhering to the surface through collision and friction, improving the cleanliness of the metal scrap, and improving the overall purity of the steel in subsequent steelmaking.

[0038] The bottom of the storage bin 302 is provided with multiple elongated holes.

[0039] This section is based on Figure 1-11 The working process described is as follows: multiple elongated holes are machined at the bottom of the storage box 302 so that impurities scattered during the stirring of internal metal scrap can be scattered out through the elongated holes on the bottom surface of the storage box 302, so that workers can collect and clean them.

[0040] A circular plate is fixedly connected to the left side of each long rod 503.

[0041] The storage bin 302 has multiple round holes on its right side, and each round hole corresponds to a round plate, with the same diameter.

[0042] This section is based on Figure 1-11The working process described is as follows: Before the multiple long rods 503 are inserted into the storage box 302, the circular plates on one side of each long rod 503 block the multiple circular holes on the right side of the storage box 302, so that when the multiple long rods 503 are inserted into the storage box 302, they are inserted into the storage box 302 through the corresponding circular holes. When the long rods 503 are inserted into the storage box 302, the circular plates on each long rod 503 push the metal scrap inside the storage box 302 to both sides. The metal scrap poured into the storage box 302 is poured in small amounts and multiple times, so that the circular plates on the long rods 503 can reach between the piles of metal scrap. When the long rods 503 are withdrawn, the workers push the metal scrap that has been stirred and impurities removed to both sides of each long rod 503 to prevent it from affecting the withdrawal of the long rods 503.

[0043] Each long rod 503 has a circular disk fixedly connected to its right side, and the diameter of each circular disk is the same as the diameter of each circular hole. When the conical blade 505 on the long rod 503 stirs the metal raw material, the circular disk blocks each corresponding circular hole to prevent the metal from scattering from the circular hole when stirring the metal.

[0044] A baffle 502 is fixedly connected to the top of the sliding frame 501.

[0045] This section is based on Figure 1-11 The working process described is as follows: A baffle 502 is fixedly connected to the top of the sliding frame 501 by welding. When multiple long rods 503 on the sliding frame 501 extend into the storage box 302, the baffle 502 above the sliding frame 501 moves to the top of the storage box 302 to cover the top of the storage box 302, preventing metal scrap from splashing out and accidentally injuring nearby workers when the internal metal scrap is stirred.

[0046] A fixed base 201 is fixedly connected to the bottom of the converter 202. A traction base 203 is rotatably connected to the front side of the fixed base 201. The movable end of the hydraulic rod 204 is fixedly connected to the upper side of the traction base 203. Another traction base 203 is fixedly connected to the fixed end of the hydraulic rod 204. The other traction base 203 is rotatably connected to the top front side of the support base 101.

[0047] This section is based on Figure 1-11 The working process described is as follows: When the converter 202 is rotated, the hydraulic rod 204 is pulled by the traction seat 203 located on its movable end and lifted upward from the converter 202 through the fixed seat 201. Thus, the converter 202 rotates around the position where the two sides of the rotating frame 102 are rotatably connected to the support seat 101, so that the furnace mouth of the converter 202 can receive the discharged metal raw materials at the opening of the storage box 302.

[0048] A method for producing medium-carbon steel using the aforementioned medium-carbon steel converter equipment includes the following steps:

[0049] S1: The metal raw materials for steelmaking are poured into the storage box 302, and the storage box 302 is moved to one side of the converter 202 by the lateral movement of the transverse shift seat 301.

[0050] S2: The converter 202 is rotated with the two sides of the tilting frame 102 as the rotation center, so that the furnace mouth of the converter 202 is tilted towards the storage box 302.

[0051] S3: The raw materials located in the storage bin 302 are poured into the converter 202 by the pusher plate 402;

[0052] S4: Before S3, multiple long rods 503 are inserted into the storage box 302, and the conical blades 505 on the long rods 503 move in a circular motion, thus agitating the metal raw materials in the storage box 302.
