Description

Technical Field

[0001] This utility model relates to the field of high-carbon ferrochrome processing technology, and in particular to a decarburization device for high-carbon ferrochrome. Background Technology

[0002] High-carbon ferrochrome is an alloy of iron and chromium with a relatively high carbon content. It is typically produced from chromium ore through smelting and has important applications in steel production and other fields. During storage, transportation, and initial production, high-carbon ferrochrome is generally in a solid state. During decarburization, it is heated and melted into a solution. In this liquid state, the atoms and ions within the ferrochrome are more reactive, allowing for more thorough contact and reaction with oxygen and decarburizing agents, significantly improving the reaction rate and decarburization effect.

[0003] Currently, oxygen blowing is used in the decarburization process. Oxygen is blown into the molten high-carbon ferrochrome, causing an oxidation reaction between the oxygen and the carbon in the ferrochrome, thus achieving decarburization. However, because the oxygen blowing location is fixed, the oxygen distribution in the molten metal is uneven. The oxygen concentration near the blowing port is too high, resulting in an overly vigorous decarburization reaction, while areas farther from the blowing port suffer from insufficient oxygen supply, leading to incomplete decarburization and uneven carbon content in the product, resulting in unstable quality.

[0004] Therefore, it is necessary to provide a decarburization device for high-carbon ferrochrome to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 A schematic diagram of a preferred embodiment of the decarburization device for high-carbon ferrochrome provided by this utility model; Figure 2 This is a schematic diagram of the overall structure; Figure 3 for Figure 1 The side sectional view shown is shown below; Figure 4 for Figure 2 The diagram shows the internal explosion structure. Figure 5 for Figure 4 The enlarged schematic diagram of part A shown below; Figure 6 for Figure 4 The enlarged schematic diagram of section B is shown below; Figure 7 for Figure 4The diagram shown is an enlarged view of section C. The decarburization device for high-carbon ferrochrome includes: a heating device 1, a connecting pipe 11 on the left side of the heating device 1, a discharge pipe 12 on the right side of the heating device 1, a driving assembly 2 inside the heating device 1, a supporting assembly 3 outside the driving assembly 2, and an oxygen injection assembly 4 inside the supporting assembly 3. The oxygen injection assembly 4 includes two symmetrical first connecting pipes 41 and two symmetrical second connecting pipes 42. The two first connecting pipes 41 are disposed inside the supporting assembly 3, penetrating the supporting assembly 3 and extending to its... Externally, the bottom of the two first connecting pipes 41 is fixedly connected to a main spray box 43 for storing oxygen. The outer surface of the two main spray boxes 43 is provided with a plurality of first nozzles 44 for gas pressurization at equal intervals. The two second connecting pipes 42 are disposed inside the support assembly 3. The two second connecting pipes 42 penetrate the support assembly 3 and extend to its outside. The bottom of the two second connecting pipes 42 is fixedly connected to an auxiliary spray box 45. The outer surface of the auxiliary spray box 45 is provided with a plurality of second nozzles 46 for gas pressurization at equal intervals. The oxygen spraying assembly 4 is provided with a conveying assembly 5 on its outside.

[0025] Heating device 1 provides heat energy for the decarburization of high-carbon ferrochrome inside. Material can be added through connecting pipe 11, and decarburized gas can be discharged during internal oxygen blowing. Drive assembly 2 enables the carrier assembly 3 to rotate synchronously. This rotation drives the main spray box 43 and auxiliary spray box 45 at the bottom of the first connecting pipe 41 and the second connecting pipe 42 to rotate synchronously. The main spray box 43 and auxiliary spray box 45 are designed to face each other, allowing the first nozzle 44 and the second nozzle 46 to blow in opposite directions. This accelerates the convection of the high-carbon ferrochrome solution between the main spray box 43 and the auxiliary spray box 45, resulting in better decarburization. Conveying assembly 5 continuously delivers gas to the interior of the oxygen injection assembly 4, providing it with energy.

[0026] The drive assembly 2 includes a drive member 21, which is installed at the bottom of the heating device 1. The output end of the drive member 21 is fixedly connected to a transmission member 22 for rotation. The transmission member 22 passes through the heating device 1 and extends into its interior. The outer surface of the transmission member 22 is rotatably connected to the interior of the heating device 1. A mixing component 23 for stirring is fixedly connected to the outer surface of the transmission member 22.

[0027] The drive component 21 is installed at the bottom of the heating device 1. By activating the drive component 21, the transmission component 22 can rotate. When rotating, the mixing component 23 can push the solution in the middle of the heating device 1 to the outside. Through the cooperation of the main spray box 43, the auxiliary spray box 45 in the oxygen spray assembly 4 and the mixing component 23, the solution inside the heating device 1 is mixed more evenly, increasing the quality of decarbonization.

[0028] The mixing component 23 includes, but is not limited to, turbine blades, propulsion blades, and anchor blades;

[0029] In this example, the mixing component 23 is preferably a turbine blade. The turbine blade can generate high-intensity shear force in a small area, enabling rapid mixing of the molten metal and rapid dispersion of oxygen into the molten metal, resulting in more uniform decarburization.

[0030] The bearing component 3 includes a mounting member 31, which is mounted on the outer surface of the transmission component 22. Three first connecting members 32 for connection are equidistantly arranged on the outer surface of the mounting member 31. The ends of the three first connecting members 32 are fixedly connected to a main ring plate 33 for providing a mounting base. The interior of the main ring plate 33 is fixedly connected to the outer surface of the first connecting pipe 41. Three second connecting members 34 are equidistantly arranged on the outer surface of the main ring plate 33. The ends of the three second connecting members 34 are fixedly connected to an auxiliary ring plate 35. The interior of the auxiliary ring plate 35 is fixedly connected to the outer surface of the second connecting pipe 42.

[0031] When the transmission component 22 rotates, it can drive the first connecting component 32 and the main ring plate 33 outside the mounting component 31 to rotate synchronously, and make the first nozzle 44 on the main spray box 43 at the bottom of the first connecting pipe 41 rotate synchronously and blow out oxygen. Similarly, the second connecting pipe 42 installed on the auxiliary ring plate 35 can rotate synchronously, so that the second nozzle 46 on the auxiliary spray box 45 at the bottom of the second connecting pipe 42 will also rotate and blow out oxygen. The main spray box 43 and the auxiliary spray box 45 are arranged opposite each other.

[0032] The delivery assembly 5 includes two main pipes 51 and two auxiliary pipes 52. The two main pipes 51 are disposed at the top of the first connecting pipe 41, and the two auxiliary pipes 52 are disposed at the top of the second connecting pipe 42. The output ends of the two auxiliary pipes 52 are fixedly connected to the outer surfaces of the two main pipes 51. A receiving member 53 is fixedly connected to the top of the two main pipes 51. A pipe body 54 for inputting gas is fixedly connected to the top of the receiving member 53. A one-way control member 55 is disposed on the outer surface of the pipe body 54.

[0033] By inserting a rotatable oxygen supply pipe device into the pipe body 54, oxygen can enter the interior of the container 53 through the pipe body 54, and the one-way control device 55 is used to prevent the gas from flowing backward. The oxygen is stored and distributed to the two main pipes 51 through the container 53, and then transported to the interior of the auxiliary pipe 52 through the main pipes 51, so that there is oxygen inside both the main spray box 43 and the auxiliary spray box 45.

[0034] The heating device 1 is provided with a first stabilizing component 6 on its top. The first stabilizing component 6 includes a cover 61, which is disposed on the top of the heating device 1. The top of the cover 61 has an annular groove 62 for maintaining rotational stability. A ring block 63 is rotatably connected inside the annular groove 62. Four support pillars 64 for providing support are equidistantly arranged on the top of the ring block 63. A ring frame 65 is fixedly connected to the top of the four support pillars 64. The inside of the ring frame 65 is fixedly connected to the outer surface of the receiving member 53. The heating device 1 is provided with a protective component 66 for maintenance. The inside of the protective component 66 is movably connected to the outer surface of the tube 54. The tube 54 passes through the protective component 66 and extends to its outside.

[0035] When the receiving member 53 rotates, the support column 64 on the ring frame 65 can drive the ring block 63 to rotate and connect inside the annular groove 62, so that the conveying assembly 5 can maintain stable rotation.

[0036] The heating device 1 is provided with a second stabilizing component 7. The second stabilizing component 7 includes a first circular groove 71 and a second circular groove 72. Both the first circular groove 71 and the second circular groove 72 are opened inside the heating device 1. A first support member 73 for maintaining rotational stability is rotatably connected inside the first circular groove 71. The top of the first support member 73 is fixedly connected to the bottom of the main spray box 43. A second support member 74 is rotatably connected inside the second circular groove 72. The top of the second support member 74 is fixedly connected to the bottom of the auxiliary spray box 45.

[0037] The first support member 73 and the second support member 74 inside the first circular groove 71 and the second circular groove 72 can provide support for the main spray box 43 and the auxiliary spray box 45 during rotation.

[0038] The working principle of the decarburization device for high-carbon ferrochrome provided by this utility model is as follows: First, high-carbon ferrochrome is added to the heating device 1 through the connecting pipe 11, and the heating device 1 provides heat energy for decarburization. At the same time, the conveying component 5 stably delivers oxygen to the main spray box 43 and the auxiliary spray box 45 of the oxygen spraying component 4 through the pipe body 54, the receiving component 53, the main pipe 51 and the auxiliary pipe 52. Then, the driving component 21 located at the bottom of the heating device 1 is activated, which drives the transmission component 22 to rotate. The transmission component 22 drives the bearing component 3 to rotate, and the bearing component 3 in turn drives the main spray box 43 and the auxiliary spray box 45 of the oxygen spraying component 4 to rotate synchronously, so that the first nozzle 44 and the second nozzle 46 on the opposing main spray box 43 and the auxiliary spray box 45 blow oxygen in opposite directions, accelerating the convection of the high-carbon ferrochrome solution. At the same time, the transmission component 22 drives the mixing component 23 to rotate, pushing the solution in the middle of the heating device 1 to the outside, and cooperating with the oxygen spraying component 4 to make the solution mix more evenly. Finally, after the decarbonization reaction is completed, the processed material is discharged through the discharge pipe 12. During the entire process, the connecting pipe 11 can also discharge the gas generated during oxygen blowing decarbonization.
