Description

Technical Field

[0001] This invention relates to an integrated operation method and apparatus for slag removal and slag receiving, mainly used for slag receiving during the slag removal process of molten metal in a ladle and for preventing slag leakage during the slag discharge process. Background Technology

[0002] Modern metallurgical production is developing towards high-end, high-efficiency, and environmentally friendly production with less pollution. The emergence of slag removal machines has increased the scenarios and functions for vertical slag removal from metal ladles. However, during the slag discharge process after slag removal, the slag leaking out of the slag rake has an adverse impact on the ground environment and other equipment, and to some extent, it can also affect production safety.

[0003] Another problem with rotating the slag discharge after slag removal is that it affects the efficiency of metallurgical production. Rotating the slag discharge after slag removal requires walking a certain path, which takes 3-5 minutes. In modern metallurgical production, this is often not allowed, and even 1 minute is very precious. Summary of the Invention

[0004] This invention proposes an integrated operation method and device for slag removal and slag receiving. It eliminates the need for rotating the slag discharge tray; instead, the tray is directly placed at the metal ladle opening. After slag removal, the tray is simply moved backward to collect the slag, significantly improving equipment efficiency. It also solves the problem of slag leakage during the rotating slag discharge process after slag removal.

[0005] The technical solution of the present invention is as follows:

[0006] A slag-receiving arm with a slag-receiving device hinged to the frame, column, or working arm of a slag remover.

[0007] After the slag rake of the slag remover closes the slag removal outlet, when it runs above the slag receiving pan, the slag is directly discharged into the slag receiving pan;

[0008] When the slag remover rotates to discharge slag into the slag hopper, in order to prevent slag from leaking out, the slag rake is suspended above the slag receiving plate. The slag that falls off the slag rake is caught by the slag receiving plate and will not leak out.

[0009] As a further improvement of the present invention, the slag receiving tray can be connected to the slag receiving arm through a take-up and put-down mechanism, or it can be directly connected to the slag receiving arm.

[0010] As a further improvement of the present invention, a rotating mechanism is provided between the slag receiving pan and the slag receiving arm, which has the dual functions of tilting the slag receiving pan to unload slag during unloading and adjusting the horizontal angle of the slag receiving pan.

[0011] As a further improvement of the present invention: in order to prevent slag from sticking to the slag receiving pan, the inner surface of the slag receiving pan is coated with a fire-resistant and anti-sticking slag coating.

[0012] Compared with the prior art, the present invention has the following positive effects: (1) It eliminates slag leakage during the slag discharge process of the slag remover; (2) The slag receiving plate is placed at the metal ladle opening, and there is no need to rotate to discharge slag after slag removal. The slag remover or working arm can simply move back to the slag receiving plate with the slag rake to discharge slag, which greatly improves the slag removal efficiency and solves the key 3-5 minute time problem that the slag remover cannot be widely used in the metallurgical process. It provides an important means for improving the quality and efficiency of metallurgy, saving energy and reducing carbon emissions, and automating unmanned production. Attached Figure Description

[0019] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings:

[0020] Example 1

[0021] like Figure 1 , Figure 2 and Figure 6 As shown, next to the metal liner 1, the slag remover 2 is mainly composed of a chassis 3, a working arm 4, and a frame 5 or column 6. A slag receiving arm 7 is hinged to the frame 5 or column 6. A receiving mechanism 8 is hinged to the front end of the slag receiving arm 7. A slag receiving plate 9 and a rotating mechanism 10 are hinged to the front end of the receiving mechanism 8.

[0022] During slag removal, the slag remover 2 moves to the slag removal position of the metal ladle 1, the slag receiving arm 7 is lifted by the lifting device 11, the retracting mechanism 8 extends or moves forward, and the rotating mechanism 10 rotates to adjust the pitch of the slag receiving plate 9 so that the slag receiving plate 9 overlaps the ladle opening of the metal ladle 1. The slag remover 2 begins to remove slag. After the slag rake 12 closes to load slag, the working arm 4 is raised until the bottom of the slag rake 12 is higher than the ladle opening, and then moves backward to carry the slag rake 12 above the slag receiving plate 9. The slag rake 12 opens and releases slag into the slag receiving plate 9. The working arm 4 then carries the slag rake 12 back to the metal ladle 1 to remove slag. This cycle continues until the slag removal is completed.

[0023] After the slag receiving pan 9 is filled with slag, the slag removal machine 2 moves, carrying the slag receiving pan 9 to the slag pot 13. The retraction mechanism 8 cooperates (extends forward or retracts backward), and the lifting device 11 descends. After the slag receiving pan 9 is aligned with the slag pot 13, the rotating mechanism 10 moves, tilting and unloading the slag in the slag receiving pan 9 into the slag pot 13.

[0024] Example 2

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, next to the metal ladle 1, a slag remover 2 is arranged, mainly consisting of a chassis 3, a working arm 4, and a frame 5 or column 6. A slag receiving arm 7 is hinged to the working arm 4, and a slag receiving plate 9 and a rotating mechanism 10 are directly hinged to the front end of the slag receiving arm 7. This device is used to solve the problem of slag leakage from the slag rake 12 during the slag removal and discharge process.

[0026] During slag removal, the slag remover 2 moves to the slag removal position of the metal ladle 1. The slag receiving arm 7 is lifted and moved forward by the lifting device 11. The rotating mechanism 10 rotates to adjust the pitch of the slag receiving plate 9 until the slag receiving plate 9 is in a horizontal state. The slag remover 2 begins to remove slag. After the slag rake 12 closes to load slag, the working arm 4 lifts and retracts, carrying the slag rake 12 to above the slag receiving plate 9 and stops. The slag remover 2 rotates back to the position of the slag rake 12 above the slag pot 13. The rotating mechanism 10 rotates the slag receiving plate 9 to the slag unloading state, and the slag flows down. The slag rake 12 opens and the slag is discharged into the slag pot 13. The working arm 4 then carries the slag rake 12 back to the metal ladle 1 to remove slag. This cycle continues until the slag removal is completed. During the entire process of rotating and discharging slag, no slag is leaked outside.
