FIELD: ferrous metallurgy.
SUBSTANCE: method comprises processing data obtained from the signals of controlled parameters of blowing (pressure and gas flow rate, tuyere position) by the wavelet analysis, normalizing the time series by the maximum value in each time series, calculating the values of wavelet factor that characterizes the structure variations in the signal, storing the calculated values of the wavelet factor, determining the extremum value of the wavelet factor at the current time moment at all levels of detailing of the signal structure, and founding the synchronous extremal values of wavelet factors at all levels of detailing.
EFFECT: enhanced reliability of testing.
