total energy input to the EAF(It is now common for 30-40% of the total energy input to the EAF to come from oxy-fuel burners and oxygen lancing. 现在氧-燃烧嘴配合氧枪吹氧所提供的能量通常占电弧炉总能量输人的30% ~ 40%。)
electric ladle preheater(However, the operating experience with the electric ladle preheater has not indicated any problem with inadequate heating of the ladle bottom as evidenced by solidified steel or difficulty in opening the pouring nozzle. 然而，使用钢包电能预热器的操作经验尚未显示出任何可以证明与钢包底部加热不足有关的问题，如钢水凝固或水口难于打开等。)
