METAL MELTS EQUILIBRIUM ESTIMATING METHOD Russian patent published in 2019 - IPC G01N11/16 G01N27/00 

FIELD: physics.

SUBSTANCE: invention relates to the technical physics and is intended for the metal alloys, mainly steels, melts physical properties parameters determination, during these dependences determining on the alloy samples by the contactless method based on the cylindrical crucible with a sample torsional vibrations study. Additional scope of application is metallurgy. Proposed is the metal melts equilibrium estimation method, in which the metal alloy sample physical properties thermal-time dependencies in the form of ν(t°_i)_heat = A_{i heat} = A_min and ν(t°_i)_cool = A_{i cool} = A_max are determined_. These signals values are memorized and displayed on the multi-channel display, wherein using the above mentioned characteristics A_i values. At temperature t°_i, exceeding the sample melting t°_i>t°_mel temperature t°_mel signals A_i from the memory device output are switched to the division unit inputs, thus receiving the output signal in the form of the K_i coefficient value, representing the A_max and A_min ratio_. Entering it into the storage device, recording the K_i coefficient, and then using as the melt under study structure equilibrium state assessment quantitative characteristic. In addition, obtaining and using the K_i = A_min/A_max coefficient value less than one K_i<1.

EFFECT: increase in the melt equilibrium estimation reliability and accuracy.
