large-and medium-sized pipes(The plant specializes in the production of hot-and cold-rolled flat products as well as in large-and medium-sized pipes. 该车间专门生产热轧和冷轧扁平材以及大、中型管材。)
larger particles segregate toward furnace center(In this case, V-shaped layers will form as shown in Figure 3. Note that the larger particles segregate toward the furnace center. 如图 3 所示，在这种情况下将形成 V 形料层。值得注意的是此时大块炉料偏向炉子中心。)
gas solubility in liquid steel(【技】气体在钢水中的溶解度受多种因素的影响，主要有：温度升高，溶解度增加；气体分压降低，溶解度降低。同时，气体在钢液中的溶解度还受钢水中不同化学元素的影响：与气体能形成化合物的元素，能提高气体在钢水中的溶解度；比铁对气体有更大亲和力的元素，能提高气体在钢水的溶解度；但一些非金属或准金属元素，如 C、 P、 S、 O、 Si 等会降低气体在钢水中的溶解度。)
partial pressure of CO in gas bubble(With the bottom injection of argon in the BOF combined-blowing practice, and the presence of hydrogen in the gas bubbles in OBM, the partial pressure of CO in the gas bubbles will be lowered in both processes when the rate of CO generation decreases. 带有底吹氩的 BOF 复吹实践和 OBM 炼钢时气泡中存在氢时，如果 CO 的产生速度下降，则这两种炼钢法气泡中的 CO 分压将会降低。)
dilute impurities in scrap(Nucor is also investing $60 million in an iron-carbide production facility on the island of Trinidad. This material will be used to supplement the scrap charge at its two plants in order to dilute impurities in the scrap to produce a better grade of steel. 纽柯钢公司目前还投资6 000万美元在特立尼达岛建造一套碳化铁生产设备。所生产的碳化铁将在其下属的两个分厂作为废钢铁的补充炉料，以便稀释废钢中的杂质，生产优质钢。)
porous argon purged tundish nozzle(The company has addressed this problem of alumina clogging in tundish nozzle with porous argon purged tundish nozzles. 该公司已采用透气型吹氩清洗中间包水口，解决了中间包水口 Al₂O₃ 堵塞难题。)
