Temperature Field and Its Influencing Factors of Heavy Rail during Quenching
Heat-treatment was emphasized for its important role to qualify the products of heavy rail, and induction quenching was one of the widely used heating process methods. The temperature field of U71Mn heavy rail during the quenching process and various kinds of factors that may influence temperature field to be distributed were simulated by the FEM software. The result shows that the main factors that influence the way that temperature field was distributed were how long the heating and keeping warm time were, and the value of the pressure of wind when cooing the steel, the difference of which would directly influence the results of the heat treatment of heavy rail. It is significantly valuable for the choice of relevant parameters for the heat treatment of U71Mn heavy rail.
