Breakout warning method, utilizing acoustics, in a continuous casting installation and apparatus for its implementation

摘要

A breakout warning method and apparatus for a continuous casting installation wherein structure-bound sound, traveling through the area of the ingot mold, is continuously picked up by a sound recorder and checked for the presence of typical frictional noises between the mold and billet. A breakout signal is emitted upon determination that there are no typical frictional noises present.
