Comprehensive utilization of metal materials for steelmaking at Baosteel

摘要

Optimization of scrap utilization,through maintaining a reasonable heavy scrap ratio,determination of scrap yield,development of substitutes for scrap,recycling of high-alloy scrap and optimization of scrap utilization technology,was investigated in this paper,in terms of the supply of metal materials,production cost,production quality and environment protection.Then,recycling of solid waste resources was discussed,and the utilization conditions and methods of slag-steel,slag-iron,steel-slag,etc.were determined.Finally,the management system for comprehensive resource utilization was introduced.
