- 摘要:
- 钢渣是炼钢过程中产生的副产物,钢渣的综合利用有利于节能减排。本文介绍钢渣的成分、组成和物理化学性质,对目前国内外钢渣处理方法进行阐述,并对不同处理方法的优缺点进行分析;论述钢渣的不同利用途径,对现行的钢渣综合利用技术进行总结和分析,进而对钢渣的综合利用提出建议和展望;在此基础上提出利用模式螺旋磁场对液态钢渣进行电磁分离的钢渣处理新技术。Steel slag is a by-product of steel production, it’s more conductive to achieve the overall requirements of energy conservation and emissions reduction by improving the comprehensive utilization of steel slag. The composition, structure,and phy-chemical property of the steel slag were introduced. The current domestic steel slag treatment process was described in detail. The different utilization methods of steel slag was discussed in the paper, the existing steel slag comprehensive utilization technology was also summarized and analyzed. Finally put forward some suggestions and prospects to the comprehensive utilization of steel slag. On the basis of this, a new separation method of steel slag treatment by a modulated helical magnetic field to separate the liquid steel slag is proposed.
