A high-temperature metallurgical slag tank slagging cover automatic pushing and supporting device according to claim 2, characterized in that, The roller group (502) is slidingly connected in the guide rail (4), and a thermal expansion gap of 5-8 mm is reserved between the guide rail (4) and the roller group (502).

4. The automatic pushing and supporting device for the slag cover of the high-temperature metallurgical slag ladle according to claim 3, characterized in that, The PLC control system (602) of the positioning module (6) is provided with an intelligent deviation correction algorithm, when the laser sensor (601) detects that the offset of the slag cover body (3) is greater than 3 mm, the telescopic rod (203) fine adjustment program is automatically triggered to differentially control the telescopic rods (203) of the two hydraulic oil cylinders (202); the stroke of the offset side push rod is shortened and the stroke of the opposite side push rod is simultaneously lengthened.

5. A slag pot comprising the automatic pushing and supporting device for the cover of a high-temperature metallurgical slag pot according to claim 4, characterized in that, Further comprising a U-shaped support (11) fixed on the rack (1) and a slag tank body (12) rotationally connected in the U-shaped support (11) through a rotating shaft, a driving motor (111) for driving the slag tank body (12) to rotate is arranged on the U-shaped support (11), the sealing plate (702) is movably abutted with the top of the slag tank body (12), the top of the slag tank body (12) is provided with a first recess (121) matched with the movable block (801), and the inner wall of the first recess (121) is provided with a second recess (122) matched with the positioning block (901).

6. A method of using the slag pot of claim 5, wherein, The method comprises the following steps: S1: initial positioning: The driving motor (111) rotates the slag tank body (12) to a horizontal position; The hydraulic oil cylinder (202) synchronously extends the telescopic rod (203) to push the slag cover body (3) to translate along the guide seat (5); S2: travel monitoring: The laser sensor (601) scans the three-dimensional pose of the slag cover body (3) in real time, when the offset is greater than 3 mm, the PLC control system (602) triggers the deviation correction program, and the telescopic rods (203) on the two sides are differentially displaced to adjust the pose of the slag cover body (3); S3: sealing linkage: The slag cover body (3) is abutted with the stop seat (101) under the pushing of the telescopic rod (203), at this time, the slag cover body (3) is located directly above the slag tank body (12), with the telescopic rod (203) continuing to move towards the slag cover body (3), the elastic telescopic sleeve (2033) automatically shrinks under the condition that the second rod body (2032) cannot move, the push rod (2034) presses the stress plate (703) to make the rotating ring (7) rotate, the rotating ring (7) pushes the sealing plate (702) downward through the connecting piece (701), and the sealing surface of the sealing plate (702) is abutted with the top wall of the slag tank body (12); S4: positioning locking: When the first rod body (2031) is displaced relative to the second rod body (2032), the steel wire rope (10) is no longer tensioned, the first elastic element (802) pushes the movable block (801) to be embedded in the first recess (121), and the second elastic element (902) releases the positioning block (901) to be clamped into the second recess (122), so that the connection and locking of the slag cover body (3) and the slag pot body (12) are realized, and the slag cover body (3) performs the sealing work on the slag pot body (12).
