Temperature data producing apparatus for high temperature moving objects.

摘要

The tip of an alloy rod (5) in a vacuum chamber (1) is remelted by radiation with an electron beam (6) from an electron gun (2) and the remelted droplets (7) fall into a mold (3) where they solidify. The droplets (7) are scanned a plurality of times through a window (10) provided on the vacuum chamber (1) by an image pickup device (11) as they pass its field of view. From the signal of the maximum level obtained during these scans, temperature data of the droplet (7) is obtained by a temperature measurement control device (12).
