METHOD FOR DETERMINING ABNORMALITIES ON POLYTHERMS OF PROPERTIES OF HIGH-TEMPERATURE MOLTEN METALS (VERSIONS) Russian patent published in 2013 - IPC G01N27/14 

FIELD: machine building.

SUBSTANCE: method involves determination of polytherms of those properties, for example kinematic viscosity, molten metal so that values of properties are obtained in the form of electric signals, which are displayed on one of the multichannel display channels. At that, polytherm values of molten metal are supplied to differentiator inlet; differentiated signals, which are displayed on the other channel of the multichannel display, are picked up from its outlet. Then, differentiated signals are supplied to a comparison unit, the output signals of which are supplied to an alarm unit inlet and the third channel of the multichannel display, as well as to the adder inlet, from the outlet of which the signals are supplied to the fourth channel of multichannel display and alarm unit.

EFFECT: obtaining additional results and more reliable information, evaluation accuracy of abnormalities on polytherms, and providing the possibility of evaluating the experiment results by semiskilled personnel.
