Description
Summary:Temperature is a vital parameter in quenching process. When cooling style was changing to air cooling, it was necessary to simulate the temperature-field of air cooling quenching. Temperature-field at each time was accomplished. Through numerical expression of experimental heat transfer coefficient curves, as well as least squares technique, the heat transfer coefficient at different temperature were calculated to specify the heat transfer coefficient of heavy rail. In this way, the temperature field of heavy rail in air cooling process was obtained simultaneously. It is significantly valuable for parameters' selection in heavy rail's technical operation.
