efficiency of heat transfer(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。)
inclusion elimination efficiency(The inclusion elimination efficiency will be reduced significantly if there are reoxidation conditions during continuous casting. 如果在连铸期间存在二次氧化的条件，那么夹杂物去除效率将大为降低。)
effect of jet striking narrow face(For narrow mold, once inclusions enter the lower flow zone created by the effect of the jet striking the narrow face, it is unlikely that they would rise by buoyancy to the free surface. 对于窄结晶器而言，只要夹杂物一进人由于流股撞击结晶器窄面效应而形成的向下流动区，它就不可能依靠浮力再上升到钢水自由面。)
result of electromagnetic braking(【技】电磁制动的效果包括：降低结晶器内金属弯月面下的钢水水平流速和弯月面的波动，防止保护渣卷人，促使保护渣均匀铺展，降低铸坯表面纵向和横向裂纹产生的几率；降低流股的向下流速和贯穿深度，有利于夹杂物上浮和均匀分布；弯月面下钢水温度得以提高，有利于保护渣吸收上浮的夹杂物，改善铸坯质量；有利于初生坯壳的均匀生长，降低角裂和漏钢的发生几率。)
