˄ 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。)
V 形料层(In this case, V-shaped layers will form as shown in Figure 3. Note that the larger particles segregate toward the furnace center. 女口图 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。)
