RAPID DIAGNOSTICS METHOD OF HOMOGENEITY OF HIGH-TEMPERATURE MOLTEN METALS Russian patent published in 2013 - IPC G01N11/00 

FIELD: metallurgy.

SUBSTANCE: rapid diagnostics method of homogeneity of molten metal by determining viscosity of an alloy specimen with known maximum viscosity and fusion point, which is taken from a melting unit and placed into a viscosimetric plant. With that, as the specified temperature, value of temperature is used, which exceeds fusion point of the alloy specimen by n°C, specimen viscosity value is compared to maximum value of viscosity of this alloy at the specimen fusion point. With that, when those values coincide, a conclusion is made on availability of homogeneous sate of molten metal, and if value v for the temperature exceeding the specimen fusion point by n°C is less than maximum viscosity value of that alloy at the specimen fusion point, a conclusion is made on absence of homogeneous state of molten metal.

EFFECT: simpler and multiple acceleration of experiments for determination of homogeneity of molten metals with possibility of implementing correction of melting modes under shop production conditions; with that, quality control of melting of this molten metal is performed during melting process.
