依赖(① Modification of nonmetallic inclusions by calcium at the end of ladle furnace treatment depends not only on the amount of injected calcium, but on the sulfur content. 钢包炉处理末期，通过加钙对非金属夹杂物进行的变性处理不仅取决于喷人钙的数量，同时还取决于钢水的含硫量。② Tapping a 300 ton heat takes from four to seven minutes and the time strongly depends on the conditions or diameter of the taphole. 出一炉 300t 的钢水需要花费 4 ~7min 的时间，出钢时间长短主要取决于出钢口使用状况或它的直径。)
