In view of meeting the requirement of railway development for straightness rail,the technology of compound straightening is applied in Panzhihua Iron and Steel CoThe research and application results show that the eligibility percents of the straightness of center and the end of rail are increased,the rail height difference is more small,and the residual stress is also reduced

Introducing the requirement of the steel rail on straightness for the passenger transport rail line,Normal straightening steel rail technique.

One important target of the high speed rail is that the heavy rail achieves the standard of straightness and residual stress of rail base should be smaller than 250MPa.
