What aspects affect the performance of submerged arc furnace?

According to the structural and working characteristics of the submerged arc furnace, 70% of the system reactance of the submerged arc furnace is generated by the short network system, and the short network is a large current working system, and the large current can reach tens of thousands of amps. Therefore, the performance of the short network determines the performance of the submerged arc furnace. For this reason, the natural power factor of the submerged arc furnace is difficult to reach more than 0.85, and the natural power factor of most furnaces is between 0.7 and 0.8, The lower power factor only reduces the efficiency of the transformer, consumes a lot of reactive work, and is charged by the power part with additional power penalty. At the same time, due to the manual control of the electrode and the stacking process, the power imbalance between the three phases increases, which can reach more than 20%, which leads to the low smelting efficiency and the increase of electricity charge. Therefore, improving the power factor of the short network and reducing the power grid imbalance is to reduce energy consumption, An effective means to improve smelting efficiency.
