Zusammenfassung:The invention discloses a method for rolling a steel rail by a universal rolling mill. The method comprises the step of providing a lubricant for at least part of a hole pattern of the universal rolling mill in a rolling process. With the adoption of the technical scheme, the metal mobility of R at an intersection on a rolled piece during rolling can be effectively improved by lubricating the hole pattern of the universal rolling mill, therefore, scale bond formed inside legs of the steel rail during rolling can be further effectively avoided.
