摘要
真空技术可显著降低钢中气体及夹杂物含量,在钢铁制造领域得到了广泛应用,目前已成为制备高品质纯净钢的主要手段。本文重点介绍了真空冶金净化的基本原理以及真空技术在高品质钢生产过程中的应用与发展。真空技术的应用显著提升了我国的钢铁冶金水平,目前高品质钢生产工艺已实现大型真空钢锭总氧含量(T.O)低于10 ppm、特殊钢连铸坯及自耗锭总氧含量不高于5 ppm的控制水平,满足了重点领域对高性能特殊钢的需求。
The application of vacuum technology in metallurgy can effectively reduce the content of gas element and inclusions in steels and it has been widely used for producing high quality steels. The development process and the application of vacuum technology in metallurgy were reviewed and the purification principle of vacuum metallurgy was introduced in this paper. The application of vacuum technology has significantly improved the metallurgy technology in China. At present, the production process of high-quality steel in China has achieved the control level of T.O <10 ppm in large vacuum steel ingots, and T.O ≤5 ppm in continuous casting billets and vacuum consumable ingots.The quality of the special steel can meet the requirements for materials with excellent performance in the key fields.
