2012年7月21日,莱钢炼钢厂开发的冶金辅料块末在线分离技术投用2个月来,冶金辅料块末在线分离系统每天直接回收30.5t对转炉冶炼过程无效的石灰粉末,每月直接节省石灰成本13.7万元,年可节约166.99万元,同时杜绝了扬尘现象,改善了周围环境;同时提高了石灰品质,转炉冶炼脱硫除磷效果提升明显;减轻了一次除尘系统的负担,提高了一次除尘效果,为维修人员点检设备创造了有利条件石灰、矿石、萤石、镁块、污泥球等冶金辅料是炼
July 21, 2012, Laiwu Steel Works developed metallurgical accessories block online separation technology put into use 2 months ago, the metallurgical accessories block off-line separation system directly reclaim 30.5t per day of the converter smelting process invalid lime powder, each Month directly save lime cost 137000 yuan, annual can save 1669900 yuan, at the same time put an end to the phenomenon of dust, improve the surrounding environment; while improving the quality of lime, converter smelting desulfurization and phosphorus removal effect to enhance significantly; reduce the burden of a dust removal system, Improve the dust removal effect, creating favorable conditions for maintenance personnel inspection equipment Lime, ore, fluorite, magnesium, sludge ball and other metallurgical materials is refining
