longitudinal off-corner subsurface crack(Longitudinal off-corner subsurface cracks are predicted to form more easily in small-corner-radius billets. 人们预测，偏离角皮下纵裂纹更容易形成于小圆角半径的小方坯中。)
sinter(【技】烧结矿：以富矿粉、返矿及粒度较粗的精矿粉为原料，通过烧结获得的形状不规则的多孔质块矿。它分为酸性烧结矿、自熔性烧结矿、熔剂性烧结矿和高碱度烧结矿。: ① Sinter is the main ferrous burden component for the blast furnaces in the European Union. 烧结矿是欧盟高炉的主要含铁炉料。② Ore particles of less than 5mm size would be blown out of the blast furnace by the strong air blast and so, to make full use of the ore, the 'fines' are agglomerated in the sister and thus are reduced to iron in the blast furnace instead of being blown away in the exhaust gases. 矿石粒度小于5 mm 时，会被强大的鼓风吹出高炉外。因此，为了充分地利用矿石，不让它随排出的炉气吹走，人们将粉矿造块生产出烧结矿，然后在高炉内还原成铁。)
coating(This coating is said to have high durability owing to the fact that both the underlying metal and the oxide coating have similar coefficients of expansion. 据说，这种涂层经久耐用，是因为基体金属与氧化物涂层的膨胀系数基本相同。)
subsurface blister(【技】存在于钢锭皮下的的气孔。它有两种形态：一种是以针状细孔形态大面积分布于钢锭皮下，这是由于钢水脱氧不足，钢水凝固时析出的氧与碳反应生成的 CO 气泡所致。这种皮下气泡主要靠强化脱氧来防止。另一种是以较大的气泡形态零散分布于钢锭皮下。这是由于钢水中含气量过高，或者是浇注系统潮湿等原因，浇注时气体析出集于皮下所致，其防止措施主要是加强原材料烘烤，降低钢水含气量，保持浇注系统和保护渣干燥。)
mill scale(Desiliconization of hot metal is carried out by using main desiliconization agents such as oxygen, mill scale, sinter fines, and iron/manganese ore fines. 铁水进行脱硅所使用的主要脱硅剂如氧气、轧钢皮、烧结矿粉以及铁锰矿粉等。)
sheet metal(【技】; 薄(钢)板: The mass-production of sheet metal can be traced to the middle of the nineteenth century when sheets of tinplate were stamped to form food containers. 金属薄板的大批量生产可以追溯到19世纪中叶，那时已将镀锡薄板冲压成食品盒。)
