Description

Technical Field

[0001] The utility model relates to the technical field of steel casting, in particular to a rotary tower for continuous casting of steel billets. Background Art

[0002] Continuous casting, that is, continuous steel casting, is a molten steel forming technology that continuously adds refined molten steel into a crystallizer and pulls the molten steel out from the bottom of the crystallizer after solidification. Usually, the tundish continuous casting metallurgical method is used. The overall process flow is that the ladle is first transported to the rotary tower through a transport device, and then the molten steel in the ladle is transported to the crystallizer through a unloading mechanism to solidify and form a shell. The ingot with liquid core is then cooled in the secondary cooling zone to make the shell grow evenly and stably. Finally, the shell is completely produced and transported to the steel rolling process for processing via a conveying mechanism.

[0003] The existing rotary tower mainly uses a fixed ladle rotary tower, which transports the ladle and injects the molten steel in the ladle directly into the fixed ladle on the rotary tower, and then transports it to the intermediate tank through the discharge pipe. However, in actual use, the bottom of the ladle located on the rotary tower is horizontal, the molten steel is not easy to be completely discharged, and slag rolls are easily formed on the refractory layer of the inner wall of the ladle, which increases the maintenance frequency.

DETAILED DESCRIPTION

[0021] The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0023] like Figures 1 to 5 As shown, a rotating tower for continuous casting of steel billets includes a base 1, a rotating motor 2, a rotating shaft 3 and a turntable 4, wherein the rotating motor 2 is arranged on the base 1, and the power output end of the rotating motor 2 is connected to one end of the rotating shaft 3, and the other end of the rotating shaft 3 is connected to the turntable 4, and a steel ladle 6 can be placed on the turntable 4, wherein a limiting groove 9 for placing the steel ladle 6 is provided on the turntable 4, and an inclined baffle 7 capable of contacting the bottom of the steel ladle 6 is provided in the limiting groove 9.

[0024] The purpose of this design is to provide a limit groove on the turntable so that the ladle can be inserted into it, and the connection between the two is tighter and safer than placing the ladle on the top. By providing an inclined baffle in the limit groove, on the one hand, it can be used with a ladle with an inclined bottom, so that the material discharge area is concentrated in the material discharge pipe area, and on the other hand, when used with a ladle with a horizontal bottom, it can be tilted to facilitate material discharge.

[0025] The invention solves the problem that in actual use of the existing turntable with a molten steel ladle, the bottom of the molten steel ladle located on the turntable is horizontal, the molten steel is not easy to be completely discharged, and slag rolls are easily formed on the refractory layer of the inner wall of the molten steel ladle, which increases the maintenance frequency.

[0026] In this embodiment, the bottom of the ladle 6 is inclined toward one side and can contact the inclined baffle 7, and a feed pipe 8 is connected to the bottom of the ladle 6. The connection between the feed pipe 8 and the ladle 6 is located at the lowest point of the inclined surface of the bottom of the ladle 6, and the inclination angle of the bottom of the ladle 6 is 5°-10°.

[0027] The purpose of such a design is to provide a steel ladle with an inclined bottom, which is supported and stabilized by the inclined baffle and the inclined section of the steel ladle.

[0028] It should be pointed out that, due to the limited overall tilt angle, a conventional steel ladle may be used if the size is appropriate, so that the bottom of the conventional steel ladle can be lifted up by the tilting baffle to make it tilt at a certain angle.

[0029] At the same time, if Figure 2 and Figure 3As shown, this embodiment provides a connection method between a rotating tower and a ladle, wherein a limit groove 9 is located at the edge of a turntable 4, and after the ladle 6 is inserted into the limit groove 9, a portion of the ladle 6 is located outside the limit groove 9, and the ratio of the area of ​​the ladle 6 located inside the limit groove 9 to the area outside the limit groove 9 is 9:1.

[0030] The purpose of this design is to facilitate the drawing out of the molten steel in the ladle from the outside by setting the limit groove at the edge of the turntable, and at the same time set a specific ratio of the area of ​​the ladle located inside the limit groove and the area outside the limit groove, so that a certain tilt can be achieved while ensuring that the ladle is fixed.

[0031] like Figure 5 As shown, another connection method between the rotary tower and the ladle is provided in this embodiment, wherein the limiting groove 9 is close to the edge of the turntable 4, and after the ladle 6 is inserted into the limiting groove 9, the ladle 6 is located in the turntable 4.

[0032] In this embodiment, an annular reinforcement bundle 10 and reinforcement ribs 5 are provided at the bottom of the turntable 4, and the annular reinforcement bundle 10 is provided at the connection between the turntable 4 and the rotating shaft 3, one end of the reinforcement rib 5 is connected to the annular reinforcement bundle 10, and the reinforcement ribs 5 are radially distributed with the annular reinforcement bundle 10 as the center.

[0033] In actual use, compared with the existing arrangement of placing the ladle on the top of the rotating tower, the technical solution provided in this embodiment is replaced with a built-in type, which requires a higher bearing capacity of the turntable. Therefore, the mechanical strength of the turntable is improved by setting annular reinforcement bundles and reinforcement ribs.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
