依据交流电弧稳定燃烧的特点和外电路条件,结合硅铁炉炉内电路的实际情况,对硅铁炉炉内交流电弧稳定性进行了分析。研究表明,相比敞开弧,硅铁炉炉内电弧燃烧更加稳定。另外,用于炼钢电弧炉的交流电弧稳定性条件cosφ<0.84不能直接用于硅铁矿热炉炉内电弧稳定性分析,需要依据电路理论建立电弧稳定性外电路条件。

According to the combustion characteristics and the external circuit conditions, AC arc stability in ferrosilicon SAF is analyzed in this paper based on the actual situation of circuit in the ferrosilicon SAF. Results of the research show that AC arc in ferrosilicon SAF is more stable compared with the open arc. In addition, the AC arc stability needs cosφless than 0.84 in electric arc furnace for steel making. This conclusion can not be directly used for ferrosilicon SAF, while AC arc stability in ferrosilicon SAF should be built according to circuit theory.
