摘要
A method for regulating metal melt throughflow through a melt throughflow aperture in a bottom nozzle of a metallurgical vessel is provided. The bottom nozzle has an upper nozzle arranged in a floor of the metallurgical vessel and a lower nozzle arranged below the upper nozzle. The method includes introducing inert gas through at least one inert gas inlet aperture into the melt throughflow aperture in the bottom nozzle, arranging a temperature sensor on or in the lower nozzle for determining a temperature in a wall of the bottom nozzle, and regulating an inert gas supply into the bottom nozzle using measurement signals from the sensor. A decrease in the temperature signals an increase of metal clogging and an increase in the temperature signals a decrease of metal clogging.
