Technical Field
[0001] The utility model belongs to the technical field of electrode core measurement, and in particular relates to a device for measuring the three-phase electrode core of a refining LF furnace. Background Art
[0002] LF furnace refining relies on the conversion of electrical energy into thermal energy for smelting. High voltage electricity is converted into low voltage and high current and transmitted to the LF furnace, and electrical energy is converted into thermal energy in the form of electric arc to smelt molten steel. The adjustment of the pole center position of the three-phase electrode is of great significance to the arc length, arc current and voltage between the electrode and molten steel in production. Therefore, in order to ensure the safety and reliability of the smelting process, the pole center position of the three-phase electrode needs to be adjusted regularly. It is usually measured manually with a ruler, but the manual measurement accuracy is low. At the same time, the measurement process is cumbersome, time-consuming and labor-intensive, which is not conducive to the efficient adjustment of the pole center position of the three-phase electrode.

[0016] like Figure 2 As shown, firstly, the first base 101, the second base 102 and the third base 103 are placed on the inner sides of the three electrodes 11 respectively. After placement, the second level 10 is used to determine whether the base is stable. The base is fine-tuned by the leveling base 8 to make the base stable, so as to further improve the accuracy of measurement and adapt to different terrain conditions. Then, the first base 101, the second base 102 and the third base 103 are connected and fixed to the three electrodes 11 respectively through the adjustable fixing belt 7.
