off-center tap hole(EAF slag carry over into the ladle is controlled using an off center tap hole and keeping a 30 tonne heel in the furnace. 通过使用偏心出钢口和在炉内保持有 30t 的浇余钢水池，使得电弧炉下渣到钢包得以控制。)
vortex over tap hole(At the end of tap, formation of a vortex over the tap hole cannot be avoided and causes furnace slag entrainment into the tap stream. 在出钢结束时，出钢口上方不可避免地会形成旋涡，从而引起出钢流裹人炉渣。)
average taphole service life(In spite of the rapid increase in the average taphole service life, its performance is not stable. 尽管出钢口平均寿命迅速提高，但其性能却不稳定。)
taphole sleeve(A BOF taphole is replaced when the inner diameter of the existing taphole sleeve becomes excessively large and tap time becomes short. 当氧气顶吹转炉的出钢口袖砖内径变得过大、出钢时间变短时，其出钢口就应更换。)
segmented taphole sleeve(① The wear pattern inside a used segmented taphole sleeve is shown in Figure 3. 一个使用过的分段式出钢口袖砖内部磨蚀形状示于图3。② For comparison, the tap time and service life of segmented taphole sleeves of similar dimensions are shown in Figure 6.为了进行比较，将类似尺寸分段式出钢口袖砖的出钢时间和使用寿命示于图6。)
BOF taphole(A BOF taphole is replaced when the inner diameter of the existing taphole sleeve becomes excessively large and tap time becomes short. 当氧气顶吹转炉的出钢口袖砖内径变得过大、出钢时间变短时，其出钢口就应更换。)
exit of mold(If the heat transfer model is used to predict the thickness of the solidified shell, at the exit of the mold, a value of about 10mm would have been obtained. 如果将该传热模型用于预测结晶器出口处的凝固坯壳厚度，那么所得的厚度值约为10 mm。)
