Method of reducing the gaping values in the web saw cut test on steel railway tracks

摘要

This invention concerns a method of reducing the gaping values of railway tracks made of steel to less than 3.6 mm. It is characteristic of this invention that the rolled and leveled rails are heated briefly, i. e., for approx. 10 to 25 sec, until reaching a maximum temperature of 100. degree. C. in the rail head and a maximum of 260° C. in the web, and then they are allowed to cool again immediately.
