Mathematical model of the temperature field of a rail and a multinozzle device for induction hardening of rail heads

A mathematical model of the temperature field of a rail is developed for designing optimum regimes for surface hardening of rail heads from induction heating by HFC, and the cooling capacity of media formed in a newly designed multinozzle device is considered. It is established that the process of c...

Zusammenfassung:	A mathematical model of the temperature field of a rail is developed for designing optimum regimes for surface hardening of rail heads from induction heating by HFC, and the cooling capacity of media formed in a newly designed multinozzle device is considered. It is established that the process of cooling of rail heads can be controlled by providing a high dispersity of the water-air mixture formed by a multinozzle cooling device with autonomous feeding of the coolant through each nozzle.[PUBLICATION ABSTRACT]
