  • Patent number: 5042700
    Abstract: In a method to determine disturbances when pouring molten metal from a container having an outlet channel, vibrations generated by the molten metal flowing from the container are measured at parts of the outlet and deviations from a desired vibrational characteristic are determined. From these vibrations disturbances such as blockages in the outlet channel, vortexes and, above all, the outflow of slag can be detected. With this method the reliability of the pouring process can be significantly increased.
