摘要
The primary blank 1, which is to be transformed into a finished rail by means of universal passes, edging passes and a finishing pass, is characterized by a symmetric ' UPSILON ' section the thickness of which always varies in the same way. It is designed to be shaped exclusively in open grooves. This primary blank 1 is roughed in a specific manner in a universal stand and undergoes a strong forging which improves the quality of the finished rail. A secondary blank is then formed which has a special shape allowing the production by universal rolling of a very accurate profile of the finished rail.
