抄録

The purpose of this study is to clarify the heat transfer coefficient between the molten magnesium alloy and roll, the temperature transition of molten metal and roll and the cooling rate of produced strip at single roll melt drag process. We applied the one dimensional heat transfer solidification analysis to melt drag process. Heat transfer coefficient was estimated from 1.42×10<sup>5</sup> to 8.95×10<sup>4 W/m</sup>2·K at roll speed of 5 to 90 m/min by comparing between analysis and experimental results such as strip thickness. The molten metal temperature at roll surface was estimated that getting to 336°C from 780°C in the nozzle, and the roll surface temperature was estimated that getting to 235°C from 20°C at a roll speed of 30 m/min. The cooling rate of strip was estimated from 1.4×10<sup>3</sup> to 1.0×10<sup>4</sup> K/s by Cα method.
