“…According to the experimental and simulation study of the reaction between graphite and oxygen in air by researcher [20,40–42]. , it is obtained that the reaction between graphite and oxygen on the surface of graphite mainly consists of the following two reactions and surface reaction rates: Based on these studies [18,43], the sublimation of the bottom surface of graphite is directly proportional to the amount of passing charge.…”

“…Bowman [19] used photogrammetry to find that the closer to the tip, the greater the electrode consumption rate, and obtained the relationship between the electrode consumption rate and the electrode diameter, current. Zeng [20] studied the effects of surface temperature, gas flow and environmental pressure on the oxidation behaviour of graphite in oxygen through experiments. The weight loss rate changes slightly at 1400∼1800°C and significantly at 2000°C.…”

Under the dual requirements of cost reduction and double carbon goal, it is more meaningful to reduce the continuous consumption of graphite electrode in ladle furnace. In this paper, the three-dimensional coupling model of electromagnetic field, heat transfer, flow field is established, and the influence of embedded steel rod on the current, temperature and continuous consumption of graphite in the electrode was studied. The current in graphite and steel rod is mainly distributed in the edge area near the left electrode, respectively. With the increase of the radius of the steel rod, the proportion of the current passing through the steel rod to the total current increases, the area of each temperature range above 500 K and the total continuous consumption rate of the electrode decrease.
