摘要： A method introducing a stirring gas through a vessel bottom, receiving a measurable mechanical vibration by at least one sensor fixed to the vessel or to a supporting frame thereof, filtering the thus detected vibration signals by a high pass filter and preferably by a low pass filter, sampling and digitizing the vibration signals for exposing them to a second filtering which is digital and calibrated upon the vessel vibration responses, sequencing the response, exposing each sequence to the calculation of a temporal moving mean square, and extracting the total effective value RMS (Root Mean Square) of the measured vibration signal therefrom. The effective value is used for controlling the stirring gas flowrate supplied to the vessel. The method can be used for a stirring stand of steel making shop ladles, converters, RH processes, electric arc furnaces, etc.
