摘要： A rail axial force measuring method which removes the influence by a residual stress existing in a rail and measures an axial force borne by the rail quickly and accurately and a rail whose axial force can be measured. The rail axial force measuring method provided comprises the steps of imparting a stress sensing portion to the rail, exciting the stress sensing portion with an excitation head, detecting a change in magnetization of the stress sensing portion as a voltage signal with a detecting head, and measuring a rail axial force from the voltage signal. The voltage signal is a Barkhausen noise signal, and furthermore a configuration is also adopted in which the stress sensing portion locally heats up the rail to a gamma phase area, and thereafter it is heat treated at a temperature lower than that of the gamma phase area so that cementite is separated out. Furthermore, the present invention provides a rail having the stress sensing portion and whose axial force can be measured.

Further, the supply quantity is controlled so that the oxygen content supplied from the lower stage tuyeres is at least 0.8 times the theoretical oxygen content of the carbonaceous mass-like inflammable matters, and the exhaust gas temperature on the packing layer of the wastes is set to 150 to 700 DEG C.
