vertical reduction furnace; reduction shaft (① After leaving the hot gas cyclone, the reduction gas is then blown into the reduction shaft via a bustle, reducing the iron oxides in counter-flow. 离开热煤气旋风除尘器后，还原煤气通过围管吹人还原竖炉，在逆流动中对铁氧化物进行还原。② Reasons for the successful development of the COREX Process were the consideration and combination of proven technologies such as direct reduction in a reduction shaft, coal gasification and melting in a fixed bed together with blast0 furnace operational practice and installations. COREX 炼铁工艺开发成功的原因是研究和综合利用了现有成熟技术，例如还原竖炉中的直接还原、固定床中的煤气化与液化以及高炉的操作实践和设备等。); reduction shaft furnace |
