我厂4号高炉首次采用槽下筛分新工艺,三年多来生产实践表明,该系统工艺流程合理,设备运行可靠,但存在布置拥挤,环境污染,控制系统不够完善的缺点.通过槽下筛分,效果显著,取得了强化冶炼,增铁降焦的效果.同时,也取得了经验教训,为推广槽下筛分新工艺提供参考。 For the first time, the blast furnace under No.4 blast furnace adopted a new screening technology. The practice of production for more than three years shows that the system has a reasonable technological process and reliable operation of the equipment, but has the disadvantages of congested layout, environmental pollution and inadequate control system. Screening, the effect is significant, and achieved the effect of strengthening the smelting, iron-lowering of the role of iron.At the same time, also gained the experience and lessons, to promote the screening of new technology under the slot to provide a reference.
