关于高效率、低成本洁净钢平台的讨论——21世纪钢铁工业关键技术之一

高效率、低成本洁净钢平台建设仍是今后几年钢厂科技创新中一项具有普适性、基础性、事关钢厂效率、质量、成本的共性关键技术,对提高企业市场竞争力具有重要意义。洁净钢平台建设需抓好铁水预处理、转炉冶炼、二次冶金、全连铸4项基础支撑型技术和优化-简捷的流程网络和动态-有序运行的物流技术这2项集成技术。当前中国洁净钢平台建设的重点是:认清协同-稳定是洁净钢平台动态运行的核心,高效恒速的连铸生产是洁净钢平台动态运行的有序之源,也是优质、节能、低成本的关键;深入进行各种铁水预处理工艺、装备的适用性研究及技术经济比较;深入研究和优化规范适用范围广、运行效率高、易于协同、成本低廉的钢水吹氩精炼工艺;大力推进真空精炼装备和技术(尤其是高效RH)优化;在炼钢厂新建或改造的设计过程中要高度重视平面布置图(流程网络)的合理化,为稳定、经济地生产高质量钢材打好基础。

Disscusion on High Efficient and Low Cost Clean Steel Production Platform：One of the key Technologies for Steel Industry in 21~（st） Centry

The high efficient and low cost clean steel production platform is a key technology for steel industry,which basicly and largely affects on the efficiency,quality and cost of the steel production,and it will final determine the marketing competitiveness enhancing of steel companies.The clean steel platform is the integration of pretreatment technology of hot metal,BOF technology,secondary metallurgy technology and constant casting speed C.C technology,and optimized-simplified process network technology and dynamic-orderly operating material flow technology.It emphasized that at present,the high efficient and low cost clean steels platform should foucs on following aspects： thoroughly understand that coordination-steady is the core of the clean steel production platform;high efficient and constant continuous casting speed C.C technology is the source for the clean steel production platform operating dynamically and orderly,and it also the key for high-quality,engery saving and low cost.
