Description

Technical Field

[0001] This application relates to the field of metallurgical technology, and in particular to a device for adding activated carbon to the liquid surface of a large-section round billet crystallizer. Background Technology

[0002] Large-section round billet crystallizers are key components in continuous steel casting, used to produce large-diameter round billets (typically greater than 300mm). They are not only the "mold" for the initial solidification of molten steel but also a core element in ensuring the internal quality of the billet and preventing serious defects. Compared to ordinary small-section crystallizers, large-section round billet crystallizers have a more specialized and complex design due to the enormous size of the billets they produce. Compared to general crystallizers, large-section round billet crystallizers have a larger opening and a wider molten steel surface area. During the crystallization process, protective slag is typically added to the surface of the molten steel to achieve the following functions: 1. The protective slag isolates the molten steel surface from air, reducing oxidation; 2. It absorbs non-metallic inclusions and floating slag, purifying the molten steel; 3. The protective slag, which absorbs inclusions, also serves as insulation, minimizing cooling at the molten steel surface. Protective slag typically uses powdered silica, carbon powder, sodium oxide, and other materials with fluxing, insulating, and melting point regulating properties.

[0003] Traditional crystallizers use a single-axis, single-metal arm to pour protective slag into the crystallizer. This structure is difficult to apply to large-section round billet crystallizers. Increasing the length of the metal arm can easily cause the protective slag to spill. Utility Model Content

[0004] Since conventional feeding devices suitable for small-volume crystallizers are difficult to apply to large-section round billet crystallizers, this utility model proposes an activated carbon feeding device suitable for the liquid surface of large-section round billet crystallizers.

[0005] This utility model is achieved through the following technical solution:

[0006] A device for dispensing activated carbon onto the liquid surface of a large-section round billet crystallizer includes: a transmission pipe, a base mounting section, a first rotating arm, a second rotating arm, and a dispenser; the dispensing device is externally fixed through the base mounting section.

[0007] A first drive cylinder is provided between the first rotating arm and the base mounting part; the first drive cylinder drives the first rotating arm to swing in the horizontal plane;

[0008] A second drive cylinder is provided between the second rotating arm and the first rotating arm; the second drive cylinder drives the second rotating arm to swing in the horizontal plane;

[0009] A third drive cylinder is provided between the dispenser and the second rotating arm, and the third drive cylinder drives the dispenser to rotate in the vertical direction;

[0010] The transmission pipe extends along the base mounting section to the dispenser, and the activated carbon moves along the transmission pipe to the dispenser and is poured out through the dispenser.

[0011] Furthermore, the basic installation unit includes a storage box, the transmission pipe is connected to the storage box, and activated carbon is stored in the storage box.

[0012] Furthermore, the basic installation unit includes a pump body located between the transmission pipe and the storage box, the pump body driving activated carbon to be transported along the transmission pipe from the storage box to the dispenser.

[0013] Furthermore, an alarm is installed on one side of the storage box.

[0014] Furthermore, the basic mounting part includes a support part and a mounting pad, wherein the support part is fixed on the mounting pad, and the mounting pad is fixed against the outside.

[0015] Furthermore, the side of the first rotating arm away from the first driving cylinder includes a first fixing device, and the transmission pipe is fixed to the first rotating arm by the first fixing device.

[0016] Furthermore, the side of the second rotating arm away from the second driving cylinder includes a second fixing device, and the transmission pipe is fixed to the second rotating arm by the second fixing device.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention increases the overall structural length of the feeding device through the linkage structure of multiple rotating arms and cylinders. The linkage of multiple cylinders controls the rotation of multiple rotating arms on the horizontal plane, thereby achieving the purpose of controlling the feeder to feed activated carbon at a designated position. This increases the feeding point of the feeder, which is beneficial for activated carbon and other protective slags to be evenly dispersed on the surface of the molten steel in the crystallizer during the feeding stage.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] Please refer to Figures 1 to 4This utility model discloses a liquid surface activated carbon feeding device for a large-section round billet crystallizer, comprising: a transmission pipe 5, a base mounting part 1, a first rotating arm 2, a second rotating arm 3, and a feeder 4; the feeding device is externally fixed through the base mounting part 1. The base mounting part 1 includes: a support part 11 and a mounting gasket 12, the support part 11 being fixed to the mounting gasket 12, and the mounting gasket 12 being externally abutted and fixed. The mounting gasket 12 is used to increase surface flatness and ensure the stability of the support part 11 during fixing.

[0030] The first rotating arm 2 and the second rotating arm 3 are multi-segment rotating arms of the delivery device on a horizontal plane, wherein a first driving cylinder 21 is provided between the first rotating arm 2 and the base mounting part 1; the first driving cylinder 21 drives the first rotating arm 2 to swing on the horizontal plane.

[0031] Similar to the first rotating arm 2, a second driving cylinder 31 is provided between the second rotating arm 3 and the first rotating arm 2; the second driving cylinder 31 drives the second rotating arm 3 to swing in the horizontal plane.

[0032] This invention effectively extends the overall structural length of the dispensing device and enhances its planar coverage by employing a linkage structure of multiple rotating arms and multiple cylinders. Through the coordinated control of multiple sets of cylinders, the multi-segment rotating arms can be precisely driven to rotate as needed on the horizontal plane, thereby flexibly adjusting the position of the dispenser 4 above the molten steel surface to ensure accurate arrival at the preset designated dispensing point. This coordinated operation of the multi-segment rotating arms and multiple cylinders significantly increases the number of dispensing points that the dispenser 4 can cover, allowing for a more uniform and widespread distribution of protective slag such as activated carbon during the dispensing process. This effectively covers the surface of the molten steel in the crystallizer, improving the uniformity and coverage efficiency of the protective slag distribution, which is beneficial for improving subsequent process effects.

[0033] A third driving cylinder 41 is provided between the dispenser 4 and the second rotating arm 3, and the third driving cylinder 41 drives the dispenser 4 to rotate vertically. The dispenser 4 is a hemispherical spoon body. When the dispenser 4 rotates vertically, activated carbon is poured into the crystallizer from the dispenser 4 by tilting.

[0034] The transmission pipe 5 extends along the base mounting part 1 to the dispenser 4, and the activated carbon moves along the transmission pipe 5 to the dispenser 4 and is poured out through the dispenser 4.

[0035] Please refer to Figures 1 to 4The basic installation unit 1 includes a storage box 13, and the transmission pipe 5 is connected to the storage box 13. Activated carbon is stored in the storage box 13. The storage box 13 is pre-stored with a certain amount of protective slag powder, i.e., activated carbon powder. By storing a specified amount of carbon powder in the storage box 13, operators can avoid continuous and frequent replenishment of activated carbon, thus reducing operating costs.

[0036] The basic installation unit 1 includes a pump body 14 located between the transmission pipe 5 and the storage box 13. The pump body 14 drives activated carbon to be transported along the transmission pipe 5 from the storage box 13 to the dispenser 4. In one feasible embodiment of this utility model, an alarm 15 is installed on one side of the storage box 13. The alarm is connected to a detection device for detecting the quality of the protective slag in the storage box 13, and the alarm emits an alarm sound or warning light to alert the operator that the protective slag level is insufficient.

[0037] The first rotating arm 2, on the side away from the first driving cylinder 21, includes a first fixing device 22, through which the transmission pipe 5 is fixed to the first rotating arm 2. Further, the second rotating arm 3, on the side away from the second driving cylinder 31, includes a second fixing device 32, through which the transmission pipe 5 is fixed to the second rotating arm 3. In this embodiment, both the first driving cylinder 21 and the second driving cylinder 31 are located above the rotating arm, and the transmission pipe 5 is located below the rotating arm, to reduce the risk of the transmission pipe 5 bending or being clamped between the rotating arms and breaking during rotation.

[0038] This invention increases the overall structural length of the feeding device through the linkage structure of multiple rotating arms and cylinders. The linkage of multiple cylinders controls the rotation of multiple rotating arms on the horizontal plane, thereby achieving the purpose of controlling the feeder 4 to feed activated carbon at a designated position. This increases the feeding point of the feeder 4, which is beneficial for activated carbon and other protective slags to be evenly dispersed on the surface of the molten steel in the crystallizer during the feeding stage.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
