Sažetak
In the frame of our investigation, mathematical model of heat transfer in free jet melt spinning process of metallic materials is developed. The calculations show that contact resistance between metal melts and substrate has a great influence on calculations of melt cooling and wheel heating rate, and must not be neglected, even if its value is very low. In our model, new method for determining contact resistance through variable heat transfer coefficient is introduced which takes into account physical properties of the casting material, process parameters and contact time/length between metallic melt or metallic ribbon, and substrate, respectively, and enables cooling and solidifying rate prediction before the experiment execution.
