Abstract
A production technology is developed for converter-steel rail at PAO MK Azovstal’. This technology includes converter casting of steel, treatment in a ladle-furnace unit, vacuum treatment, chill casting of steel, rolling of ingots and blanks, and surface quenching of rail with high-frequency current heating. A batch of R65 rail is produced from K76F steel. Tests show that the rail produced by the proposed technology complies with Ukrainian State Standard DSTU 4344:2004. Heat-treated R65 rail made from K76Φ steel is now in industrial production.
