Description

An automatic eye-opening and plugging machine for submerged arc furnace production Technical Field

[0001] The utility model relates to the technical field of eyelet opening and blocking machines, in particular to an automatic eyelet opening and blocking machine for submerged arc furnace production. Background Art

[0002] The submerged arc furnace is also called the electric arc furnace or the resistance furnace. It is mainly used for reducing and smelting raw materials such as ores, carbonaceous reducing agents and solvents. When the submerged arc furnace is in use, if you want to obtain the molten and high-temperature liquid materials in the submerged arc furnace, you need to open the furnace eye of the submerged arc furnace (i.e. open the eye), and the high-temperature liquid materials in the submerged arc furnace will flow out of the submerged arc furnace through the furnace eye; after all the liquid materials in the submerged arc furnace have flowed out, the furnace eye is blocked with taphole mud (i.e. blocked the eye). At this point, the work of opening and blocking the eye of the submerged arc furnace is completed. The eye opening machine is one of the key equipment in front of the submerged arc furnace. The quality of its operation directly affects the production efficiency and production safety of the blast furnace.

[0003] Please refer to the announcement number CN208487971U for a hole-opening and plugging machine for an electric arc furnace. In this patent, it is stated that "the traditional hole-opening and plugging machine needs to move horizontally continuously to test the centering when switching between opening and plugging. The operation is cumbersome and time-consuming, and inaccurate centering is prone to occur, affecting the normal operation of the electric arc furnace." The above embodiment uses a ring structure to connect the hole-opening machine and the mud gun, so that the hole-opening and plugging machine can be quickly switched, thereby eliminating the centering step and improving work efficiency. However, the hole-opening and plugging machine in the above embodiment needs to be manually switched between opening and plugging. Due to the heavy weight of the equipment, the operation is more cumbersome and it is not convenient to achieve flexible switching. In addition, the hole-opening machine rotates during the switching process, and the gun mud therein is easy to fall off, resulting in a waste of resources. The present application proposes another technical solution to solve this technical problem.
