Abstract
The tip of an alloy rod in a vacuum chamber is remelted by radiation with an electron beam from an electron gun and the remelted droplets fall into a mold where they solidify. The droplets are scanned a plurality of times through a window provided on the vacuum chamber by an image pickup device as they pass its field of view. From the signal of the maximum level obtained during these scans, temperature data of the droplet is obtained by a temperature measurement control device.
