Method and apparatus for monitoring the melting process in vacuum arc furnaces |
摘要 |
A method and apparatus for vacuum arc furnaces monitors the arc by spectrum analysis of the arc's light obtained with a radiation receiver. Upon the occurrence of spectrum lines indicating vaporization of the crucible material, the melting process is stopped or adjusted to extinguish the arc burning on the crucible which vaporized the crucible material for the spectrum analysis.
