千叶五号高炉配置了由川崎自己设计的喷煤系统。新近开发的喷吹控制系统及其管路系统,可准确控制各个风口的喷吹量,设备维修量最少,因为喷吹量的控制是在无机械驱动部件的情况下完成的。构成该喷吹系统的装备,既可将细矿粉、碳酸钙和转炉灰尘向风口进行单一喷吹,也可混合喷吹。可利用该系统向风口喷吹各种粉剂,控制铁水成份,如[Si]和[S]。 使用结果表明,该系统具有下述良好性能: (1)总喷次量控制的精确度为最高喷吹量的±1％; (2)各风口任意喷吹时的喷吹量控制精确度为最高喷吹量的±3％。 自一九八四年十月一日该系统竣工以来,运转一直顺利。
Chiba No. 5 blast furnace equipped with Kawasaki own design of coal injection system. The newly developed injection control system and its piping system, can accurately control the amount of each tuyere blowout, the least amount of equipment maintenance, because the injection volume control in the absence of mechanical drive components to complete the case. Composition of the injection system equipment, both fine powder, calcium carbonate and converter dust to the tuyere single injection, can also be mixed injection. The system can be used to blow a variety of powder to the tuyere, control of hot metal components, such as [Si] and [S]. The results show that the system has the following good performance: (1) The accuracy of the total spray volume control is ± 1% of the maximum injection volume; (2) The accuracy of the injection volume control at each blowhole is The maximum injection volume of ± 3%. Since the system was completed on October 1, 1984, it has been operating smoothly.
