Abstract
In a method and a device for controlling vibrations of a metallurgical vessel that occur while gas is being injected into liquid molten metal located in the metallurgical vessel, a certain total amount of gas per unit of time is injected into the liquid molten metal, and the total amount of gas being is injected into the liquid molten metal through a number of individual nozzles in the metallurgical vessel, measured values correlating with the vibrations of the metallurgical vessel occurring are being measured during the injection, wherein while keeping the total amount of gas injected per unit of time largely constant, the amount of gas injected from individual nozzles per unit of time is changed in dependence on the measured values that are measured and correlate with the vibrations of the metallurgical vessel occurring.
