攀钢洁净钢生产实践

Production Practice of Clean Steel in Pangang

简要介绍了攀钢炼钢厂的装备及工艺技术水平,叙述了攀钢近年来为实现洁净钢生产,在铁水预处理、转炉冶炼、钢水精炼(脱硫、脱氧、脱磷及夹杂物控制)等方面所作的改进,以及在350 km/h高速铁路用钢、抗H2S腐蚀石油管坯钢等典型钢种上的应用,实现了wT[O]≤0.001 5%,w[S]≤0.005%,w[P]≤0.010%,氧化物夹杂物级别≤1.0级洁净钢的生产。

The equipment and technical level of steelmaking plant in PISCO（Panzhihua Iron Steel Co.） have been introduced briefly.To achieve the production of clean steel in recent years,some effective technologies in hot metal pretreatment,converter smelting,desulfurization,deoxidation and dephosphorization in the process of refining,and inclusion control have been developed and applied.In addition,the applications of these technologies in some steel grades such as 350 km/h high speed rail steel and H2S corrosion resistance steel for petroleum tube blank have been shown as well.On this basis,it achieves the production of clean steel whose wT[O]≤0.001 5%,w[S]≤0.005%,w[P]≤0.010% and level of oxide inclusions is not more than 1.0.
