Description

Technical Field

[0001] The utility model relates to the technical field of electroslag furnace protection covers, in particular to an electroslag furnace protection cover. Background Art

[0002] A slag furnace is a special smelting equipment that uses the heat energy generated by the remelting current to melt the consumable electrode inserted into the slag pool. After the metal droplets are cleaned by the slag liquid, they are crystallized into electroslag ingots in a water-cooled crystallizer. The electroslag furnace is an indispensable production equipment for special steel plants. Most electroslag furnaces are open, and the air humidity is high, which will cause pore defects in the steel ingots and increase the hydrogen content. If the hydrogen content in the steel is high, white spots may be produced, resulting in scrapping and losses. Therefore, a protective cover is required to take gas protection measures during electroslag remelting.

[0003] According to the description of an electroslag furnace atmosphere protection cover disclosed on the patent website (authorization announcement number: CN 215799807U), "The utility model discloses an electroslag furnace atmosphere protection cover, including an upper protective cover, a lower protective cover arranged above the crystallizer, and an adjustment rod arranged between the outer side of the upper protective cover and the outer side of the lower protective cover. The adjustment rod is a telescopic rod composed of an inner rod and an outer rod, and the inner rod and the outer rod are locked by a locking screw. The upper part of the adjustment rod is connected to the top of the side of the upper protective cover, and the lower part of the adjustment rod is connected to the bottom of the side of the lower protective cover. The cross-section of the upper protective cover is in the shape of a letter and extends in the circumferential direction to form a cylindrical structure. The upper protective cover and the lower protective cover of the utility model are each provided with a cooling liquid cavity inside, and the sealing is achieved by plugging in. Under the premise of ensuring that the height can be adjusted, the sealing is guaranteed, the leakage of the cooling liquid is avoided, and the safety is improved. Moreover, the lower protective cover is close to the crystallizer, and the cooling liquid it responds to is more, which ensures that it can have a good cooling effect."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, since the device transports the coolant to the interior of the upper protective cover and the lower protective cover through the coolant inlet pipe, the crystallizer is cooled by circulating the coolant inside the upper protective cover and the lower protective cover. When the coolant absorbs heat and its own temperature rises, it needs to be circulated and replaced. However, the liquid inlet pipe and the liquid outlet pipe are both arranged near the top of the protective cover. When the cooled coolant enters the interior of the protective cover, only the coolant near the top will be discharged, and the coolant at the bottom cannot circulate, so the cooling effect is not good. Therefore, it is necessary to improve the electroslag furnace protective cover to solve the above problem. Utility Model Content
