Description

Technical Field

[0001] The utility model relates to the field of ferrosilicon casting, and particularly relates to a ferrosilicon alloy casting system. Background Art

[0002] After ferrosilicon alloy is smelted in a submerged arc furnace, it needs to be poured into a ladle. The ladle is hoisted by a traveling crane to the upper part of the pouring port of the cooling mold. The operator operates the ladle to pour the ferrosilicon alloy into the cooling mold for cooling. After cooling, the formed ferrosilicon material is lifted and transferred to the finished product area for crushing. However, in the prior art, the cooling molds are all fixed, and the traveling crane needs to be continuously operated to move the ladle to the corresponding cooling mold for tilting and pouring. This not only has high requirements for the movement position of the high-temperature ladle (the movement of the high-temperature ladle is relatively dangerous), but also the high-temperature flue gas generated during pouring diffuses around, affecting the surrounding environment. Content of the Utility Model

[0003] In order to solve the above problems, the utility model provides a ferrosilicon alloy casting system.

[0004] The utility model is realized by the following technical solutions:

[0005] A ferrosilicon alloy casting system includes a moving track and its protective cover body arranged in the casting area. A plurality of cooling molds for casting and cooling ferrosilicon alloy are arranged on the moving track. When the cooling molds cast and cool the ferrosilicon alloy, they enter the protective cover body to remove the high-temperature flue gas.

[0006] Further optionally, the protective cover body includes a casting cover body and an adsorption cover body that are fixedly connected in the front and back directions. The lower parts of the casting cover body and the adsorption cover body are supported and fixed by support columns.

[0007] Further optionally, the protective cover body spans across the upper part of the moving track. A casting groove hole is opened at the top of the casting cover body, and a closed baffle is arranged at the lower part of the edge of the casting groove hole.

[0008] Further optionally, a collection groove is arranged directly below the casting groove hole, and an adsorption pipe is connected to the tail end of the adsorption cover body.

[0009] Further optionally, the casting area is separated from the finished product area on one side by a partition wall. A transport track perpendicular to the moving track and extending into the casting area is arranged in the finished product area, and a transport trolley is arranged on the transport track.

[0010] Further optionally, a movable traveling crane is arranged in the upper space of the moving track. A ladle is connected to the lower part of the traveling crane through a steel wire rope.

[0011] Compared with the existing technology, the beneficial effects of the present utility model are as follows: By providing a plurality of cooling molds that can move along the moving track, during pouring, the cooling molds are moved into the protective cover body that generates negative pressure. In this way, when pouring ferrosilicon alloy, it is not necessary to move the ladle multiple times. It is only necessary to move the cooling molds along the moving track, which greatly improves the pouring efficiency, and the high-temperature flue gas generated during pouring will not diffuse outward to improve the surrounding environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:

[0017] As Figure 1 shown, a ferrosilicon alloy pouring system includes a moving track 2 arranged in the pouring area 1 and its protective cover body. A plurality of cooling molds 9 for pouring and cooling ferrosilicon alloy are arranged on the moving track 2. When the cooling molds 9 pour and cool the ferrosilicon alloy, they enter the protective cover body to remove the high-temperature flue gas.

[0018] The protective cover body includes a pouring cover body 3 and an adsorption cover body 7 that are fixedly connected in communication with each other before and after. The lower parts of the pouring cover body 3 and the adsorption cover body 7 are supported and fixed by support columns 4.

[0019] The protective cover body straddles the upper part of the moving track 2. A pouring slot hole 5 is opened at the top of the pouring cover body 3. The pouring slot hole 5 can ensure that the steel wire rope above the ladle 11 passes through and enters, so that the ladle 11 can completely enter the interior of the pouring cover body 3. A closing baffle 6 is arranged at the lower part of the edge of the pouring slot hole 5. The closing baffle 6 can prevent the high-temperature flue gas from diffusing outward and polluting the environment.

[0020] A collection tank 10 is arranged directly below the pouring slot hole 5. The collection tank 10 can collect the ferrosilicon alloy leaked during pouring and prevent the leaked ferrosilicon alloy from diffusing outward and causing safety accidents. An adsorption pipe 8 is connected to the tail end of the adsorption cover body 7.

[0021] As Figure 3As shown in the figure, the pouring area 1 is separated from the finished product area 14 on one side by a partition wall 13. The finished product area 14 is provided with a transport track 15 that is perpendicular to the moving track 2 and extends into the pouring area 1. A transport trolley 16 is arranged on the transport track 15. Such an arrangement is more reasonable, integrated with the cooling and transportation, and the operation is more convenient and efficient.

[0022] As Figure 2 shown in the figure, a movable overhead crane 12 is arranged in the upper space of the moving track 2. A ladle 11 is connected to the lower part of the overhead crane 12 by a steel wire rope, and the overhead crane 12 is supported on the side wall of the workshop for moving and lifting.

[0023] The implementation principle of the ferrosilicon alloy pouring system in the embodiment of the present application is as follows:

[0024] When pouring ferrosilicon alloy (as Figure 2 shown in the figure), operate the movable cooling mold 9 to move on the moving track 2, move to the lower part of the protective cover body and stop. Then operate the overhead crane 12 to move the ladle 11 into the pouring cover body 3 of the protective cover body, and make the steel wire rope hoisted on the upper part of the ladle 11 enter into the pouring trough hole 5. Tilt and pour the ladle 11 to pour the ferrosilicon alloy into the lower cooling mold 9. The ferrosilicon alloy liquid moves along the cooling mold 9 and is filled. After filling, stop pouring. After pouring is completed, continue to move forward and move out of the pouring cover body 3 for static cooling, and the next cooling mold 9 moves into the pouring cover body 3 to continue pouring, realizing the rapid cyclic pouring of multiple cooling molds 9. When pouring ferrosilicon alloy in this way, there is no need to move the ladle 11 multiple times (the ladle has a high temperature and is very easy to be dangerous), and only need to move the cooling mold 9 along the moving track 2, which greatly improves the pouring efficiency, and the safety during pouring is also greatly improved;

[0025] During the whole pouring process, the adsorption pipe 8 with negative pressure (the adsorption pipe 8 is connected to the dust collector) makes the adsorption cover body 7 generate negative pressure, and adsorbs and processes the high-temperature flue gas generated by the pouring of the ladle 11 in the connected pouring cover body 3, effectively avoiding the diffusion of the high-temperature flue gas and improving the surrounding environment.

[0026] After the ferrosilicon alloy in the cooling mold 9 is cooled, operate the overhead crane 12 (at this time, the ladle 11 is not pouring and is on the moving trolley) to lift and transfer the ferrosilicon plate material on the cooling mold 9 onto the transport trolley 16, and move to the finished product area 14 along the transport track 15 by the transport trolley 16, realizing the closed-loop processing of the whole cooling and transportation, and greatly improving the recycling efficiency of the cooling mold 9.
