CONTROL METHOD OF WEAR OF REFRACTORY LINING OF METALLURGICAL MELTING VESSEL Russian patent published in 2012 - IPC G01B11/25 

FIELD: metallurgy.

SUBSTANCE: initial position and orientation of laser scanner relative to coordinate system of converter inclination axis is set by means of pre-determined permanent marks. First, scanning of refractory lining is performed by laser scanner in its initial position at orientation towards converter neck, at simultaneous scanning of several temporary marks. Position of temporary marks relative to coordinate system of laser scanner is determined so that position of temporary marks can be calculated in coordinate system of inclined converter axis. Then, laser scanner is moved to one or several new positions opposite the converter, and at the same time, temporary marks are scanned and positions of temporary marks are determined within the coordinate system of laser scanner. Also, calculation of position of temporary marks within coordinate system of laser scanner is made relative to the above calculated position of temporary marks relative to coordinate system of converter inclination axis and calculation of new position and orientation of laser scanner relative to the coordinate system of converter inclination axis is made. After that, inner profile of refractory lining of converter is formed of the data on the points, which is obtained by scanning with laser beam at various positions of laser scanner.

EFFECT: higher quick action.
