A method of determining disturbances when discharging molten metal from a
metallurgical container having an outlet into a receiving container. In
the first step of this process, one directly or indirectly detects
mechanical vibrations caused by the discharge of molten metal through the
outlet. Thereafter, a second property is measured; the second property so
measured varies during the discharge of molten metal from the first
metallurgical container to the receiving container. Then, one calculates a
sensitivity constant based upon the measuring of the second property.
Thereafter, a comparison is made between the vibrations detected by the
measuring device with a desired vibrational characteristic, wherein the
desired vibrational characteristic is defined in part by the sensitivity
constant; the comparison is analyzed to determine the existence of the
disturbances within the outlet, and actions are then taken to cause the
disturbance(s) to cease.
