centreline segregation(During the soft reduction the strand is lightly pressed just before the final solidifying to prevent centreline segregation and porosity. 为避免中心线偏析和疏松,在轻压下期间,铸坯即将最终凝固之前对铸坯进行轻微压下。)
off-center tap hole(EAF slag carry over into the ladle is controlled using an off center tap hole and keeping a 30 tonne heel in the furnace. 通过使用偏心出钢口和在炉内保持有 30t 的浇余钢水池,使得电弧炉下渣到钢包得以控制。)
EBT electric arc furnace(The company supplied the complete electric steelmaking plant with an annual capacity of 600, 000 tonnes comprising a 150t EBT electric arc furnace with slag-free bottom tapping, a ladle heating furnace, a vacuum degasser for secondary metallurgy and four-strand continuous caster for rounds with diameters ranging from 210 to 310mm. 该公司提供了一套年生产能力 60 万 t 的电炉炼钢设备,其中包括一座具有无渣炉底出钢功能的 150t 偏心炉底出钢电弧炉、一座钢包加热炉、一台二次冶金用真空脱气装置以及一台用于浇铸直径210 ~ 310mm 圆坯的四流连铸机。)
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。)
