第十五届全国炼钢学术会议文集 全量铁水预处理的讨论 张龙强，田乃媛，徐安军 （北京科技大学冶金与生态工程学院，北京 100083） 摘 要：铁水全量“三脱”预处理的价值不能仅仅局限于冶炼低硫、低磷钢种上，应从流程、效率、节能 减排、工序匹配及成本诸多方面考虑。本文分析了铁水预处理功能的演进，认为其实际功能已超越了原来 对质量调控的范畴，逐渐演进为工序及工序间的质量、能量以及协调缓冲的调节器；从 6 个方面对全量铁 水进行“三脱”的必要性进行了探讨，指出新一代大型钢厂全量铁水 “三脱”的模式是建立起高效低成本 的洁净钢生产平台、增强产品竞争力、推动我国钢铁工业快速高效发展的必然之选。 关键词：中国钢铁工业；铁水预处理；转炉；脱磷 中图分类号：TF701 Discussion on Necessity of All Hot Metal Pretreatment ZHANG Long-qiang, TIAN Nai-yuan, XU An-jun ( Metallurgical and Ecological Engineering School, University of Science and Technology Beijing, Beijing 100083, China) Absract: The total volume of hot metal pretreatment values can not be limited to the smelting low sulfur, low phosphorus steel. Many factors should be considered such as flow, efficiency, energy-saving, matching processes and cost. This paper analyzes the evolution of hot metal pretreatment function, pointed out that the actual function has already gone beyond the original scope of quality control, and gradually evolved into the processes and process quality, energy and coordination buffer regulator; the need for the whole of hot metal pretreatment were discussed from six aspects. The new generation of large-scale steel plant represents the future of Chinas steel industry. It is needed that all hot metal shoud be pretreated. This mode may establish high efficient low-cost clean steel production platform, enhance the competitiveness of products, and promote the rapid development of Chinas steel industry. Keywords: Chinas steel industry ；hot metal pretreatment ；converter ；dephosphorization 国家“十一五”优化发展冶金工业的规划中明确指出了钢铁工业未来的发展方向：淘汰落后、鼓励企 业跨地区集团化重组、建设新钢铁基地等
