Heat transfer in the melt-spinning process

In the case of continuous casting of metal ribbons with the melt-spinning process on the industrial scale, a larger quantity of melt could lead to a slow excessive warming of the chilling wheel, which would further lead to solidification of a ribbon at non-uniform conditions and increased wear of the wheel. The primary goal of our work was to determine to what extent the release of heat during the contact of the melt/ribbon on the circumferential surface of the chilling wheel affects its surface temperature rise, and inversely how much elevated temperature of the chill wheel surface effect on metal ribbon cooling rate and its solidification velocity. The influence of the contact resistance and chill wheel cooling mode on cooling and solidification rate over ribbon thickness is outlined.
