Abstract
Apparatus for the detection and evaluation of process parameters arising during the remelting of an electrode (31) to a metallic block (32) in a vacuum arc furnace detects deviations of at least one process parameter from a predetermined course and uses them to locate faults in the electrode and/or in the metal block (32).
Claims16
Apparatus for detecting the location of a fault in a metallic block during the remelting of an electrode in a vacuum are furnace to form said block, said apparatus comprising
- means for monitoring a first process parameter,
- means for monitoring a second process parameter,
- means for continuously correlating the first process parameter to the second process parameter,
- means for comparing the actual correlation of parameters so monitored to the ideal correlation of said parameters for a fault-free electrode, and
- means for determining the position of faults in the block from deviations between the actual correlation and the ideal correlation.
