METHOD FOR DETERMINING MELTING UNIT CAPACITY Russian patent published in 2012 - IPC C03B37/07 

FIELD: power industry.

SUBSTANCE: method for determining the melting unit capacity involves measurement of electromagnetic emission in the form of its two-dimensional distribution by its fixing by means of a video camera in the form of video image raster. After that, cross section area of the jet for the current raster is determined by measuring the melt jet width in raster lines with its further averaging. Then, cross section of the jet is determined, the distance passed with the incident jet is fixed during the time between two adjacent video cameras, by measuring the shift of jet shape in image pixels with further determination of actual length, and instantaneous capacity of melting unit is determined as per actual values of cross section area of jet and as per the distance passed with it. At that, electromagnetic emission is passed through light filter for detection of internal brightness non-homogeneities of the melt jet, and then, in addition, the passed distance of incident jet in video image elements is fixed by determining the shift of internal brightness non-homogeneities in the jet image in two adjacent frames with further determination of actual length, and as per current values of cross section area of the jet and as per its passed distance fixed as per fluctuations of the jet and as per internal brightness non-homogeneities there determined is the melting unit capacity.

EFFECT: improving the accuracy of determination of the melting unit capacity.
