Abstract

The paper gives consideration to nitrogen behavior when blowing steel with gaseous nitrogen through bottom and submersible tuyeres. Positive effect of nitrogen on physical and mechanical characteristics of rails is determined provided that nitrogen concentration doesn’t exceed 0.025%. This effect is possible due to formation of high-melting vanadium carbides.
