fire wall; furnace wall; oven wall; wall; sidewall (① As melting proceeds the efficiency of heat transfer to the scrap and bath drops off and more heat is radiated from the arc to the sidewalls. 随着熔炼的进行，对废钢和熔池的传热效率下降，电弧辐射热更多地传向炉墙。② Some of the benefits attributed to foamy slag in EAF are decreased heat losses to the sidewall, improved heat transfer from the arcs to the steel, reduced power and voltage fluctuations, reduced electrical and audible noise, increased arc length without increasing heat loss and reduced electrode and refractory consumption. 电弧炉使用泡沫渣的优点是：降低热量传向炉墙造成的热损、改善电弧向钢水的传热、降低电功率和电压波动、降低电源音频噪声、增加电弧长度但不增加热损失以及降低电极和耐火材料消耗。) |
