摘要

摘要在降低成本和实现双碳目标的双重要求下，降低石墨电极在钢包炉中的连续消耗更有意义。本文建立了电磁场、传热、流场的三维耦合模型，研究了埋置钢条对电极中电流、温度和石墨连续消耗的影响。石墨和钢条中的电流分别主要分布在靠近左侧电极的边缘区域。随着钢条半径的增加，通过钢条的电流占总电流的比例增加，每个温度范围的面积在500以上 K和电极的总连续消耗率降低。

Effect of steel rod embedded in electrode on continuous consumption of graphite by using numerical simulation

ABSTRACT 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.
