等轴晶区(The relation between the intensity of stirring and the ratio of the equiaxed crystal zone in carbon steel is shown in Figure 12. In the upside of a billet, the equiaxed crystal zone increases monotonically with the increase of M-stirring intensity. 碳素钢搅拌强度与等轴晶区比之间的关系示于图 12。在小方坯上部,等轴晶区随着结晶器搅拌强度的增加呈单调递增。)
过渡区(The use of a separator plate limits the amount of liquid steel that penetrates and mixes within the strand, thereby reducing the length of the intermix zone. 使用钢种隔离板限制了铸坯内贯穿与混合的钢水量,从而减少了混钢区长度。)
˄ 形软熔带(【技】倒 V 形软熔带一般出现在冶炼强度高、中心气流大、炉缸活跃稳定、热量充足的高炉中。这种软熔带由于中心气流发展,炉缸活跃,对煤气的阻力较小,煤气能利用率高,可以得到较好的生产指标;同时,煤气流相对集中于中心,边缘气流较小,可减轻边缘热负荷和煤气对炉墙的冲刷作用,有利于延长高炉寿命。: If the ore and coke layers are relatively uniform in thickness in the radial direction, then the inverted V-shaped cohesive zone is obtained. 如果矿层和焦层在径向上的厚度较为均匀,那么即可获得倒 V 形软熔带。)
轻压下区(The dynamic soft reduction technique enables an adaptation of the soft reduction zone to the actual position of the crater end in the strand during casting. 动态轻压下技术能在连铸期间使轻压下区与连铸坯液相穴末端的实际位置相匹配。)
