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

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.
