摘要 由于钢制品性能要求越来越苛刻,人们开发了在炼钢生产流程去除有害杂质的各种工艺技术,使杂质元素含量达到极低的水平。简要评述了钢中5大杂质元素硫、磷、氮、氢、氧对钢制品的危害,去除原理和工艺技术以及目前所能达到的极低含量的水平。 With growing demands of steel quality, purity of steel becomes more and more important, steel purity is con- trolled by a wide range of metallurgical technology and operating practices in order to achieve low or ultra-low content level of harmful elements (S, P, N, H, 0). This paper reviews the different aspects of steel products, removal principle and technology, and attaining the required ultra-low level of sulfur, phosphorus, nitrogen, hydrogen and oxygen.
