Technical Field

[0001] The utility model relates to the field of arc furnace electrodes, in particular to an arc furnace electrode fixing structure. Background Art

[0002] An electric arc furnace is a device that uses electric energy to generate high temperatures through electric arc discharge to melt metal or other materials. It is usually composed of electrodes, electric arcs, furnace bodies, and cooling systems. The working principle of an electric arc furnace is to open holes in the top of the furnace, fix the electrodes with fixed structures, and insert the electrodes into the furnace body through the holes in the top of the furnace by moving the fixed structures to work. After the work is completed, the electrodes are separated from the electric arc furnace by moving the fixed structures upwards, and the electrodes are removed from the fixed structures.

[0003] At present, in the process of driving the electrode to move, a fixed structure of an electric arc furnace directly drives the fixed structure to move downward and upward through a hydraulic device. When installing and removing the electrode, the fixed structure is always located above the electric arc furnace, which is inconvenient for workers to install and remove the electrode on one side of the electric arc furnace. Therefore, the utility model proposes an electric arc furnace electrode fixing structure. Utility Model Content
