Description

Technical Field

[0001] The utility model belongs to the technical field of iron and steel metallurgy, and particularly relates to a water slag flushing device for slag-containing smelting of ferroalloys. Background Art

[0002] In the submerged arc furnace smelting industry, slag-containing smelting is relatively common in ferroalloy smelting. In the previous transformation of submerged arc furnace smelting, since the previous smelting was slag-free smelting (such as ferrosilicon alloy) and there was no need to pour slag, after changing the smelting variety to slag-containing smelting (such as silicomanganese alloy, ferrochrome alloy), it was all slag-containing smelting, and the amount of discharged slag was large, so it was necessary to pour the slag. Because there was no water flushing system in the old workshop, it was necessary to use a slag trough to pour and drain the slag into the slag pond. During the cleaning process of the slag trough after pouring, it needed to be cleaned by personnel, with a relatively high temperature, a large amount of labor, and risks. When pouring the slag, a large amount of flue gas overflowed and the dust was large. Content of the Utility Model

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A water slag flushing device for slag-containing smelting of ferroalloys includes a water slag pond and a water slag trough. One end of the water slag trough is provided with a slag discharge port, and the slag discharge port is arranged in the water slag pond. The inner bottom surface of the water slag trough slopes downward in the direction towards the water slag pond. A slag pouring die head is arranged on the water slag trough. A circulating water flushing mechanism is arranged between the slag pouring die head and the water slag pond. The circulating water flushing mechanism includes a water spraying pipe, a water pump and a water outlet. The water spraying pipe is arranged in the slag pouring die head, the water outlet penetrates through the bottom of the water slag pond, a filter screen is arranged in the water outlet, and the water pump is respectively connected with the water spraying pipe and the water outlet through water pipes.

[0006] In order to further implement the utility model, the water slag trough is of a U-shaped structure, and the two extended ends of the U shape are provided with open slag discharge ports. The discharge port of the slag pouring die head is arranged inside the closed end of the U shape, and the bottom end of the discharge port does not contact the inner bottom surface of the water slag trough.

[0007] In order to further implement the utility model, the slag pouring die head is arranged at one end of the water slag trough far away from the water slag pond, and the axis of the slag pouring die head is perpendicular to the bottom surface of the water slag trough.

[0008] In order to further implement the utility model, the slag discharge port penetrates through the side wall of the water slag pond.

[0009] In order to further implement the utility model, the water spraying pipe penetrates through the side wall of the slag pouring die head, and the water spraying pipe is arranged at 2 / 3 of the height of the slag pouring die head.

[0010] In order to further implement the utility model, the water pump adopts a high-pressure water pump.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows:

[0012] The present utility model connects the water outlet, water pump and water spray pipe in sequence by means of a water pipe. The water pump connecting pipe is in the water slag pool. The water pressure of the water pump is used to spray the water in the water slag pool into the water slag tank to realize the cooling of the slag obtained by casting with circulating water, and then the water flow is used to wash into the water slag pool.

[0013] The present utility model effectively controls the smoke and gas overflow pollution to the environment caused by casting waste slag and productive slag, and prevents environmental protection incidents; the circulating flushing mechanism cools the red slag during the casting process of the slag and then flows into the water slag pool through the water slag tank; the personnel control the casting speed and stop the water supply, so there is no need for manual cleaning of the slag tank in the high-temperature environment after casting the slag, reducing the manual labor intensity and the safety risks that may be caused by working in the high-temperature environment.

[0014] The present utility model conducts a water flushing transformation on the dry slag tank, and the sanitary environment of the on-site area is better after the process improvement of the ferrosilicon slag smelting.

[0015] The present utility model can reduce the phenomenon of smoke and dust overflow during the casting process, and there is no need for people to pry the slag in the high-temperature environment, reducing the harm of manual labor in the high-temperature environment.
