浇注水口(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，如钢水凝固或浇注水口难于打开等。)
浇注区(A funnel mold is a continuous steel casting mold with an enlarged pouring region in the top center area of the cavity, which facilitates insertion of a submerged entry nozzle (SEN) for filling the cavity with molten steel (Figure 1). 漏斗形结晶器是一种连续铸钢用结晶器，在它的内腔上部中心区有一个扩大的浇注区，以便浸人式水口 (SEN) 插人，将钢水注人(结晶器)内腔(图 1)。)
