介绍了中冶南方工程技术有限公司开发的炼钢石灰在线筛分加料系统的工艺路线和技术方案。该系统通过在石灰料仓下设置一种振动筛分装置,在保证转炉生产节奏的前提下对石灰进行块末分离,能有效杜绝石灰粉末被转炉烟气抽吸带入除尘系统,在提高石灰利用率、稳定转炉冶炼操作和保障一次除尘系统运行等方面具有显著效果,适用于新建或改建炼钢工程,具有较高的应用参考价值。
The technological route and technical scheme of on-line lime-lime screening feeding system developed by MCC Engineering Co., Ltd. are introduced. The system sets up a vibrating screening device under the lime silo to separate the lime from each other in the premise of ensuring the rhythm of the converter. It can effectively prevent the lime powder from being sucked by the converter flue gas into the dust removal system, Utilization rate, stable converter smelting operation and the protection of a primary dust removal system have significant effects, etc., suitable for new or revamp steelmaking project, with high application value.
