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。)
continuous bloom/billet caster(The Steel Company has completed installation of a continuous bloom/billet caster, a roll grinder, a roll former, two plate marker and a hot dip galvanizing line. 该钢铁公司现已完成了一台大方坯/小方坯兼用型连铸机、一台轧辊磨床、一台辊弯成形机、两台板材打印机和一条热浸镀锌生产线的建设。)
continuous slab/bloom caster(The last section of structural steel framing for the more than $260 million continuous slab/bloom caster under construction at the Sparrows Point plant has been erected. 雀点厂在建的一台价值逾 2.6 亿美元的板坯/大方坯兼用型连铸机的最后一段结构钢框架已竖起。)
large nonmetallic inclusions in ingot(【技】钢锭中尺寸大于 l00μm 的非金属夹杂物。多半为铁锰硅酸盐、铝酸盐或莫来石、刚玉等。其主要来源是耐火材料的浸蚀物或钢水二次氧化的产物。为减少钢锭中的大型夹杂物，在出钢和浇注过程中应采取措施防止各种夹杂物进人钢水：对碳锰含量较低、硅铝含量较高的钢种，应防止钢水二次氧化；对碳锰含量较高、硅铝含量较低的钢种，则应防止耐火材料的浸蚀。)
