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.

A method of determining disturbances when discharging molten metal from a metallurgical container having an outlet, said method comprising: providing a measuring device, capable of detecting mechanical vibrations, in contact with a part of the outlet of the container to directly detect mechanical vibrations of the part generated by molten metal being discharged from the container through the outlet; comparing the vibrations detected by said measuring device with a desired vibrational characteristic; analyzing the comparison of the vibrations detected with said desired vibrational characteristic to determine the existence of a blockage in a discharge channel defined by the outlet of the container by determining when the detected vibrations attenuate to a degree with respect to said desired vibrational characteristic that is indicative of a blockage in the discharge channel defined by the outlet; and alleviating the blockage of the outlet upon the determination of the attenuation of the vibrations to said degree.
