Description

Technical Field

[0001] This utility model relates to the field of material feeding for casting different types of steel, specifically a material feeding device for mixing different types of steel. Background Technology

[0002] Mixed casting of dissimilar steel grades is a complex and systematic process involving numerous process parameters. Efficiently selecting the optimal parameters is fundamental to ensuring stable production on the casting machine. Achieving optimal parameters requires ensuring the accuracy and feasibility of each process parameter, necessitating more refined continuous casting operation techniques and skill levels. During the steel casting process, a feeding device is required. Traditional feeding devices typically only feed one type of molten steel at a time and cannot control the molten steel flow rate in real time, resulting in poor performance. Therefore, this application proposes a feeding device for mixed casting of dissimilar steel grades to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a feeding device for mixing different steel grades, so as to solve the problem mentioned in the background art. This technical solution can realize the mixing of medium carbon 235B and medium carbon 355B to reduce costs, save the cost of using tundishes, and improve the steel yield.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mixing and feeding device for different steel grades, comprising an upper chamber, two molten steel conduits inserted and installed at the bottom of the upper chamber, each of the two molten steel conduits being equipped with a sealing component, and multiple vertical pipes inserted and installed at the bottom of each of the two molten steel conduits, a sealing plate being fixedly installed at the end of the molten steel conduit away from the upper chamber, a servo motor being installed on the outside of the sealing plate, a screw being fixedly installed on one side of the servo motor, one end of the screw penetrating the sealing plate and being rotatably connected to the sealing plate, and a threaded sleeve being threadedly connected to the outside of the screw, the threaded sleeve being located in the inner cavity of the molten steel conduit, and a round pipe being fixedly installed on one side of the threaded sleeve, with a sealing plug fixedly installed at one end of the round pipe.

[0005] Preferably, the sealing assembly includes a stepper motor located outside the molten steel conduit, and a rotating rod is fixedly installed on one side of the stepper motor. One end of the rotating rod passes through the outer wall of the molten steel conduit and is rotatably connected to the outer wall of the molten steel conduit. A baffle is fixedly installed on one end of the rotating rod, located inside the molten steel conduit, and the baffle matches the inner diameter of the molten steel conduit.

[0006] Preferably, a base is fixedly installed on the outer wall of the stepper motor, and the base is fixedly connected to the bottom of the upper compartment.

[0007] Preferably, a base two is fixedly installed on the outer wall of the servo motor, and the base two is fixedly connected to the outer wall of the molten steel conduit.

[0008] Preferably, a fixing sleeve is fitted and fixedly installed on the outer wall of the molten steel conduit, and the outer wall of the fixing sleeve is fixedly connected to the outer wall of the base.

[0009] Preferably, the threaded sleeve has multiple circular holes, and each of the multiple circular holes has a circular rod slidably connected to its inner cavity. One end of each of the multiple circular rods is fixedly connected to the outer wall of the sealing plate.

[0010] Preferably, a partition is fixedly installed in the inner cavity of the upper compartment, and the partition is curved.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up two molten steel conduits and multiple vertical pipes, the internal space of the upper chamber is divided into two independent cavities by a partition. Medium carbon 235B molten steel and medium carbon 355B molten steel can be temporarily stored in the two independent cavities respectively. This allows the medium carbon 235B molten steel and medium carbon 355B molten steel to enter the corresponding molten steel conduits respectively, and then be discharged into a tundish through multiple vertical pipes. This achieves the mixed casting of medium carbon 235B molten steel and medium carbon 355B molten steel, saving costs.

[0013] 2. By incorporating a servo motor, a screw, and a sealing plug, the servo motor can be driven to rotate the screw when adjusting the mixing ratio of medium carbon 235B molten steel and medium carbon 355B molten steel. The screw rotates the threaded sleeve, which in turn moves the circular tube. The circular tube then moves the sealing plug inside the molten steel conduit. By using the sealing plug to block the flow, the amount of molten steel discharged from the vertical pipe can be controlled, thus achieving the purpose of adjusting the mixing ratio of medium carbon 235B molten steel and medium carbon 355B molten steel.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figs. 1 to 4 This utility model provides a technical solution: a mixing and feeding device for different steel grades, including an upper chamber 1. Two molten steel conduits 3 are inserted and installed at the bottom of the upper chamber 1. Each of the two molten steel conduits 3 is equipped with a sealing component, and multiple vertical pipes 4 are inserted and installed at the bottom of each of the two molten steel conduits 3. A sealing plate 12 is fixedly installed at the end of the molten steel conduit 3 away from the upper chamber 1. A servo motor 11 is installed on the outside of the sealing plate 12. A screw 13 is fixedly installed on one side of the servo motor 11. One end of the screw 13 passes through the sealing plate 12 and is rotatably connected to the sealing plate 12. A threaded sleeve 14 is threadedly connected to the outside of the screw 13. The threaded sleeve 14 is located in the inner cavity of the molten steel conduit 3. A round pipe 17 is fixedly installed on one side of the threaded sleeve 14. A sealing plug 18 is fixedly installed at one end of the round pipe 17.

[0021] In this embodiment, during use, molten medium carbon 235B steel and molten medium carbon 355B steel are temporarily stored in the upper chamber 1. The molten medium carbon 235B and molten medium carbon 355B steel are then discharged through two steel conduits 3 and multiple vertical pipes 4 at the bottom of the conduits 3, entering the tundish for mixing. If it is necessary to stop the output of molten medium carbon 235B and molten medium carbon 355B steel from the upper chamber 1, a sealing assembly is used to seal the steel conduits 3, preventing the molten medium carbon 235B and molten medium carbon 355B steel from entering the tundish. In the water conduit 3, if it is necessary to adjust the mixing ratio of medium carbon 235B molten steel and medium carbon 355B molten steel in the future, the servo motor 11 can be driven to drive the screw 13 to rotate. The screw 13 drives the threaded sleeve 14 to move. The threaded sleeve 14 drives the round tube 17 to move. The round tube 17 drives the sealing plug 18 to slide inside the molten steel conduit 3. By using the sealing plug 18 to seal in the molten steel conduit 3, the amount of molten steel discharged from the vertical pipe 4 can be controlled, thereby achieving the purpose of adjusting the mixing ratio of medium carbon 235B molten steel and medium carbon 355B molten steel.

[0022] As an optional implementation, the sealing assembly includes a stepper motor 6, which is located outside the molten steel conduit 3. A rotating rod 7 is fixedly installed on one side of the stepper motor 6. One end of the rotating rod 7 passes through the outer wall of the molten steel conduit 3 and is rotatably connected to the outer wall of the molten steel conduit 3. A baffle 8 is fixedly installed on one end of the rotating rod 7. The baffle 8 is located in the inner cavity of the molten steel conduit 3 and matches the inner diameter of the molten steel conduit 3.

[0023] In this embodiment, if it is necessary to seal the inside of the molten steel conduit 3 during use, the stepper motor 6 needs to be driven so that the stepper motor 6 drives the rotating rod 7 to rotate. The rotating rod 7 drives the baffle 8 to rotate inside the molten steel conduit 3. After the baffle 8 rotates to a horizontal state, the baffle 8 is used to seal the inside of the molten steel conduit 3. If it is necessary to keep the inside of the molten steel conduit 3 unobstructed afterward, the stepper motor 6 can be driven again. The operation is convenient.

[0024] As an optional implementation, a base 5 is fixedly installed on the outer wall of the stepper motor 6, and the base 5 is fixedly connected to the bottom of the upper compartment 1.

[0025] In this embodiment, during use, the base 5 is used to fix the stepper motor 6 to the bottom of the upper compartment 1, ensuring the stable performance of the stepper motor 6 during subsequent operation.

[0026] As an optional implementation, a base 2 10 is fixedly installed on the outer wall of the servo motor 11, and the base 2 10 is fixedly connected to the outer wall of the molten steel conduit 3.

[0027] In this embodiment, during use, the base 2 10 is used to fix the servo motor 11 to the outer wall of the molten steel conduit 3, ensuring the stable performance of the servo motor 11 during subsequent operation.

[0028] As an optional implementation, a fixing sleeve 9 is fixedly installed on the outer wall of the molten steel conduit 3, and the outer wall of the fixing sleeve 9 is fixedly connected to the outer wall of the base 10.

[0029] In this embodiment, during use, the base 10 is fixed to the outer wall of the molten steel conduit 3 by setting the fixing sleeve 9, thereby improving stability.

[0030] As an optional implementation, the threaded sleeve 14 has multiple round holes 15, and each round hole 15 has a round rod 16 slidably connected to its inner cavity. One end of each round rod 16 is fixedly connected to the outer wall of the sealing plate 12.

[0031] In this embodiment, during use, the horizontal movement trajectory of the threaded sleeve 14 is limited by the cooperation of multiple round rods 16 and round holes 15.

[0032] As an optional implementation, a partition 2 is fixedly installed in the inner cavity of the upper compartment 1, and the partition 2 is bent.

[0033] In this embodiment, during use, the internal space of the upper chamber 1 is divided into two independent cavities by the partition 2, which are used to temporarily store medium carbon 235B molten steel and medium carbon 355B molten steel, and then used for subsequent mixed casting of different steel grades.
