[0023] The utility model is further described below in conjunction with the drawings and specific embodiments. It is necessary to point out here that the description of these embodiment modes is used to help understand the utility model, but does not constitute the limitation of the utility model. The specific structure and functional details disclosed in this paper are only used to describe the example embodiment of the utility model. However, the utility model can be embodied in many alternative forms, and should not be understood as being limited in the embodiments described herein.

[0024] As Figure 1 shown, Figure 1 The structure schematic view of the slag breaking tool provided by the embodiment of the application; a slag breaking tool for outside refining processing, the slag breaking tool comprises a main body 100, a first operation part 200 and a second operation part 300, and cooperates to realize efficient breaking of ladle slag. Wherein:

[0025] As Figure 1 shown, the main body 100 is arranged on the upper part of the liquid surface of molten steel and can be lifted; the main body 100 can be arranged on the upper part of the liquid surface of molten steel and can be lifted. The main body 100 can be configured to be made of a solid material to withstand high temperature and heavy load, while ensuring stability during lifting. The lifting mechanism of the main body 100 can be electric or hydraulic drive to realize accurate control.

[0026] As Figure 1 shown, the first operation part 200 is fixedly arranged at one end of the main body 100 close to the liquid surface of molten steel, the first operation part 200 can be lifted synchronously with the main body 100, and the first operation part 200 is used for breaking the ladle slag surface.

[0027] As Figure 1 shown, the first operation part 200 is fixedly arranged at one end of the main body 100 close to the liquid surface of molten steel, and can be lifted synchronously with the main body 100. The main function of the first operation part 200 is to break the ladle slag surface, which can penetrate the slag layer on the surface of molten steel. When selecting the material and structure of the first operation part 200, high temperature and wear resistance are considered to ensure the reliability of the first operation part 200 in long-term use.

[0028] As Figure 1As shown, the second working part 300 movably sheaths the first working part 200 and can move up and down along the axial direction of the first working part 200. When the main body 100 moves towards the lower part of the liquid surface of the molten steel, the molten steel can relatively push the second working part 300 and the first working part 200 to separate, and the first working part 200 and the second working part 300 can successively penetrate the slag surface of the ladle. When the main body 100 moves out of the liquid surface of the molten steel with the first working part 200, the second working part 300 can move downwards on the first working part 200 and scrape the adhered slag on the outer wall of the first working part 200.

[0029] As shown, Figure 1 the second working part 300 movably sheaths the first working part 200 and can move up and down along the axial direction of the first working part 200. When the main body 100 moves towards the lower part of the liquid surface of the molten steel, the molten steel can relatively push the second working part 300 and the first working part 200 to separate. To allow the first working part 200 and the second working part 300 to successively penetrate the slag surface of the ladle, the efficiency and area of slag breaking are increased.

[0030] When the main body 100 moves out of the liquid surface of the molten steel with the first working part 200, the second working part 300 can move downwards on the first working part 200 due to the gravity of the second working part 300, and the adhered slag on the outer wall of the first working part 200 is scraped by the second working part 300. Through the lifting control of the main body 100, the penetration ability of the first working part 200 and the scraping function of the second working part 300, efficient and safe slag breaking operation is realized.

[0031] In an optional embodiment, the slag breaking tool in the present application is used for auxiliary operation of the secondary refining process, and the working principle of the slag breaking tool is as follows: the slag breaking tool comprises a main body 100, a first operation member 200, and a second operation member 300, the main body 100 is arranged to be liftable above the liquid surface of molten steel, the first operation member 200 is fixedly arranged at one end of the main body 100 close to the liquid surface of molten steel, the first operation member 200 can be synchronously lifted with the main body 100, the first operation member 200 is used to break the slag surface of the ladle, and the second operation member 300 is movably sleeved on the first operation member 200 and can move up and down along the axial direction of the first operation member 200. In actual secondary refining operation, the main body 100 is operated to move towards the lower part of the liquid surface of molten steel, the second operation member 300 sleeved on the first operation member 200 is pushed by the molten steel, the second operation member 300 moves away from the first operation member 200, and the first operation member 200 and the second operation member 300 break the slag surface of the ladle in sequence. While the first operation member 200 breaks the slag, the second operation member 300 can break the slag with a larger slag breaking area to achieve the required slag breaking area. After the slag breaking operation is completed, the main body 100 is operated to move and drive the first operation member 200 to move out of the liquid surface of molten steel, and then the second operation member 300 moves down under the action of gravity and is sleeved on the first operation member 200, until the second operation member 300 is completely sleeved on the first operation member 200. During the downward displacement of the second operation member 300, the slag adhering to the outer wall of the first operation member 200 is synchronously scraped off, thereby forming a rapid cleaning process and avoiding manual cleaning operation, which is more efficient and safer.

[0032] As shown in Figure 1 In an optional embodiment, one end of the first operation member 200 towards the liquid surface of molten steel is tapered. Such a tapered end helps to improve the penetration force, so that the first operation member 200 can more easily penetrate the slag surface of the ladle. The sharp tip of the taper reduces the contact area, thereby generating higher local pressure when contacting the slag surface, so that the slag breaking process is more efficient.

[0033] As shown in Figure 1 In an optional embodiment, the outer diameter of the second operation member 300 is greater than the outer diameter of the first operation member 200. The outer diameter of the second operation member 300 is greater than the outer diameter of the first operation member 200. This enables the second operation member 300 to completely cover the first operation member 200, which on the one hand increases the slag breaking area on the basis of the first operation member 200, and on the other hand provides additional support and protection.
