[0037] A method for cleaning a reduction furnace chassis, using an automatic cleaning system for the reduction furnace chassis, the cleaning method comprising the following steps:

[0038] (1) The cleaning rack 1 is accurately mounted on the reduction furnace chassis 3. Before cleaning, the reduction furnace chassis 3 is placed on the ground and the upper surface of the reduction furnace chassis 3 is in a horizontal state. Then, three positioning pins 31 that are not in a straight line are inserted into the reduction furnace chassis 3. Then, the cleaning rack 1 is placed on the reduction furnace chassis 3, and the upper ends of the positioning pins 31 are inserted into the positioning holes of the cleaning rack 1. In this way, the cleaning rack 1 and the reduction furnace chassis 3 are accurately positioned, and all electrodes 4 are in the cleaning rack 1.

[0039] (2) The control center controls the rotating assembly and the lateral adjustment assembly to work simultaneously, so that the cleaning assembly stops working when it is coaxial with the electrode 4 on the reduction furnace bottom plate 3. Before controlling the vertical adjustment assembly to move downward, the electrode 4 and the dry ice spray head 10 must be positioned first, and the rotating assembly and the lateral adjustment assembly are controlled so that the dry ice spray head 10 can work around the axis of the electrode 4 to be cleaned, that is, the outer ring sleeve 9 is kept coaxial with the electrode 4.

[0040] (3) The vertical adjustment assembly is controlled to move downward by the control center, and stops working when the lower end of the cleaning assembly is sealed with the upper surface of the reduction furnace bottom plate 3. When the vertical adjustment assembly moves downward, the flexible dustproof retaining ring 18 on the outer ring sleeve 9 is in full contact with the upper surface of the reduction furnace bottom plate 3 and is sealed to prevent the dust generated during the cleaning process from leaking out.

[0041] (4) The control center first controls the dust collector to work, then controls the dry ice blasting to work, and finally controls the cleaning component to work. Before cleaning, the dust collector works first and the dry ice blasting works first, or they can work simultaneously.

[0042] (5) Control the cleaning rotating motor 13 on the cleaning assembly to drive the dry ice nozzle 10 to slowly rotate 360 ​​degrees in the forward direction, and then slowly rotate 360 ​​degrees in the reverse direction to return to the initial position. The dry ice nozzle 10 rotates around the electrode 4 and cleans it. The forward and reverse directions are used for two cleaning operations. If two cleaning operations are not thorough enough, three, four or more cleaning operations can be selected. Dry ice cleaning will not cause damage to the electrode 4.

[0043] (6) Control the cleaning rotating motor 13 to stop working, then control the dry ice blasting to stop working, and finally control the dust collector to stop working. Before stopping cleaning, the dry ice blasting stops working before the dust collector, and the dry ice blasting and the dust collector can also stop working synchronously.

[0044] (7) Control the vertical adjustment component to move upward. The vertical adjustment component moves upward to facilitate the adjustment of the position of the cleaning component and prevent interference between the lower end of the cleaning component and the electrode 4 when the rotating component and the lateral adjustment component are working.

[0045] (8) After the vertical adjustment assembly is moved upward, repeat steps (2) to (7). By repeating steps (2) to (7), all the cleaning work of the electrodes 4 can be completed.

[0046] (9) After all electrodes 4 on the reduction furnace bottom plate 3 have been cleaned, the cleaning rack 1 is removed from the reduction furnace bottom plate 3 .
