据了解,迄今国内单相电弧炉仍多为人工在炉旁操作手轮调节电弧,进行熔炼。炽热的炉体,有毒的烟尘,刺耳的噪声,对炉旁工人健康是不利的;熔炼的速度及质量又随操作者熟练程度不同而异。为节约电力,要求在电炉的熔炼时间上争分夺秒,采用自动调节电极是 It is understood that so far the domestic single-phase electric arc furnace is still more manual operation of the hand wheel to adjust the arc, the melting. Hot furnaces, toxic fumes, harsh noises are detrimental to the health of workers at the furnace; the speed and quality of smelting vary with the proficiency of the operator. In order to save electricity, it is required to race against time in the smelting time of the electric furnace, and to adopt the automatic adjusting electrode
