距离三相电极弧光最近的炉壁耐火材料厚度太薄,无法继续冶炼,是多数炼钢电弧炉被迫停炉中修的主要原因。 一、电弧炉热源 点状热源和三相供电制是炉壁热点产生的根源。
The refractory thickness of the furnace wall closest to the arc of the three-phase electrode is too thin to continue smelting, which is the main reason that most steel-making electric arc furnaces are forced to shut down. First, the electric arc furnace heat source point-shaped heat source and the three-phase power system is the source of the hot wall.
