7. The flow guide device for the tap hole of a submerged arc furnace according to claim 6, characterized in that: The disassembly assembly comprises a tilting rod (701) arranged on the upper part of the square kit (2); a support rod (702) is fixedly connected to the lower surface of the tilting rod (701); a strip groove (703) is formed through the end of the tilting rod (701); and a lever (704) is slidably connected to the interior of the strip groove (703).

8. The flow guide device for the tap hole of a submerged arc furnace according to claim 7, characterized in that: The disassembly assembly further comprises a collar (705) arranged inside the square kit (2); a protrusion (706) is fixedly connected to the top of the collar (705); a slot (707) is provided on the upper surface of the protrusion (706); and the lever (704) is clipped inside the slot (707).

9. The flow guide device for the tap hole of a submerged arc furnace according to claim 8, characterized in that: A slide groove (708) is provided in the middle of the upper surface of the square kit (2), and the protrusion (706) slides inside the slide groove (708). A fulcrum groove (709) is provided at the edge of the upper surface of the square kit (2), and the support rod (702) is clamped inside the fulcrum groove (709).

10. A method of use, using the guide device for a tap hole of a submerged arc furnace as claimed in claim 9, the method of use is as follows: S1. Installation: Place the carbon core (3) into the square kit (2) so that the carbon core (3) is placed inside the collar (705), then use taphole mud to seal the connection port between the square kit (2) and the carbon core (3), fully insert the arc plate (511) into the pin hole (513) on the outer surface of the long rod (510), start the cleaning assembly to push the long rod (510) into the interior of the carbon core (3) to seal the carbon core (3); S2, flow opening and protection: the cleaning component is started to drive the long rod (510) to move out of the carbon core (3), and the closed carbon core (3) is opened. At the same time, the protection component drives the protection plate (603) to cover the outer surface of the square kit (2) under the transmission of the cleaning component, so as to achieve a protective effect. At this time, the molten steel will flow out of the carbon core (3) into the guide groove (8); S3, cleaning: after the molten steel is drained, the arc plate (511) on the outer surface of the long rod (510) is removed and replaced with a grinder (512), the cleaning assembly is started to rotate and push the long rod (510) into the carbon core (3), and the inner wall of the carbon core (3) is polished and cleaned. After the end of the long rod (510) penetrates the carbon core (3), the grinder (512) at the end position is removed and replaced with an upper arc plate (511), and the cleaning assembly is started again to drive the long rod (510) to move out of the carbon core (3); S4. Replacement: With the protection component open, install the disassembly component on the upper part of the square kit (2), then push the tilting rod (701) to drive the ring (705) to move and collide with the cannon mud seal (4). After the cannon mud seal (4) is broken, take out the discarded carbon core (3) and replace it with a new carbon core (3).
