我厂使用的白云鄂博矿石中氟、钾、钠、稀土等元素含量较高,给高炉冶炼造成了很多的困难,通过二十多年的科研和生产实践,在原料准备、工艺操作和设计、筑炉、设备各方面采取了适宜的措施和改进生产指标和经济效果有了明显的提高。其 中,高压水螺旋铜管风口的研制成功和推广使用,有效地改善了高炉的生产条件,取得了突出的经济效果。一、风口大量破损是包钢高炉生产的关键问题由于矿石的特殊性,高炉冶炼过程发生
I plant using the Bayan Obo ore fluoride, potassium, sodium, rare earth and other elements higher, to the blast furnace smelting caused a lot of difficulties, through more than 20 years of scientific research and production practices in raw material preparation, process operation and design, Building furnaces, equipment, take all appropriate measures to improve production and economic indicators have been significantly improved. Among them, the high-pressure water spiral copper tuyere developed and promoted the use of effectively improve the blast furnace production conditions, and achieved outstanding economic results. First, a large number of damaged tuyere Blast furnace production is a key issue due to the special nature of the ore, blast furnace smelting process took place
