对钢液精炼所需的保温和加热,作为钢包炉的重要功能,历来为冶金工作者所关注。ASEA-SKF、VAD和LF钢包炉因其具有电弧加热功能,无论在适炼的钢种方面,浇钢温度的精确度方面,还是在操作工艺的自由度以及成品钢的质量方面,都要比没有外加热装置的VOD、AOD等钢包炉来得优越些。但这些加热的钢包炉使用的都是三相交流电极电弧。由于钢包炉的内径相对较小,不适于高功率和长时间的三相电弧加热,尤其是热点处的耐材最易消蚀。
The need for insulation and heating of molten steel, as an important function of ladle furnace, has always been the concern of metallurgical workers. ASEA-SKF, VAD and LF ladle furnaces, thanks to their arc-heating function, are more suitable than steel for precision steels, as well as for the degree of freedom in the operation of the process and the quality of the finished steel There is no external heating device VOD, AOD ladle furnace superior. However, these heated ladle furnaces use three-phase AC electrode arcs. Due to the relatively small inner diameter of the ladle furnace, it is not suitable for high-power and long-term three-phase arc heating, especially the heat-resistant refractory material is the most easily eroded.
