PRODUCTION OF HEAVY TYPES OF RAIL FROM CONTINUOUSLY CAST BILLETS OF OXYGEN CONVERTER STEEL

The process for producing K-76 rail steel which has a composition similar to M-75 (GOST 8160-63) martensite steel is described. The rail steel was smelted in a 10-ton oxygen converter at the Novo-Tula metallurgical plant. Production and heat-treatment details are given, and tests performed on rails from the steel are described. Tabulated data show a comparison between the plasticities of the transverse and longitudinal samples, thus confirming the presence of anisotropy. Tests were made, on R-75 and R-65 rails, and the results are presented. The conclusions were that the rails made from continuous cast billets of oxygen converter steel are almost as good in quality as rails produced at the Azovstal plant in regards to mechanical properties. However, the former rails are better because they are free of stitch-type nonmetallic inclusions.
