1 概况西林钢铁公司1号高炉于2001年10月经过大修扩容改造,炉容由100m~3扩至130m~3。同时,随着6000m~3/h制氧工程的投入运行,除供炼钢用氧外,尚有部分富余,加之2000年5月喷煤工程的投入运行,为1号高炉富氧喷煤提供了条件。与高炉扩容改造同步,增设了富氧工艺,用微机系统进行控制,进一步完善了炼铁生产工艺,为高炉操作者增加了调剂手段,也为稳定炉况、强化高炉
1 Overview Xilin Iron and Steel Company No. 1 blast furnace in October 2001 after a major expansion expansion transformation, furnace capacity expanded from 100m ~ 3 to 130m ~ 3. At the same time, with the 6000m ~ 3 / h oxygen project put into operation, in addition to oxygen for steelmaking, there are still some surplus, combined with the coal injection project in May 2000 put into operation for the No. 1 blast furnace oxygen-rich PCI Conditions. In line with the blast furnace capacity expansion and transformation, an oxygen enrichment process was added and the microcomputer system was used for control. This further improved the iron production process and added adjustment measures to the blast furnace operators as well as stabilizing the furnace condition and strengthening the blast furnace
