Abstract: A great deal of saturated steam produced during converter melting is not often effectively used at steelworks ,while on the other hand the VD refining unit needs definite slight superheated steam. The results of converter steam supply to VD refining show that the saturated steam of heat reservoir of two sets of 100 t converter completely satisfies the requirement of VD refining with, steam pressure 0. 8 〜1.0 MPa and superheat extent 10 - 15 ℃.After VD refining of liquid for 15 min, the [ H] is ≤1.5 X 10^-6, total [ O] ≤15 x 10^-6 and de-nitrogen rate of liquid ≥25% . The key problems and solution schemes for application of converter saturated steam to 100 t VD refining unit are presented in this article.

摘要： 转炉生产过程中产生大量的饱和蒸汽,但没有得到有效的利用;而VD精炼需要一定的微过热蒸汽。转炉蒸汽供应VD精炼的结果表明,2座100 t转炉的饱和蒸汽得到有效利用,转炉蓄热器饱和蒸汽完全满足VD使用要求,供给VD的蒸汽压力0.8～1.0 MPa,过热度10～15℃。钢水经VD 15 min精炼后,[H]≤1.5×10^-6,总[O]≤15×10^-6,脱氮率≥25%。文中介绍了转炉余热蒸汽在100 t VD精炼设备上的应用难点及解决方案。
