Abstract
The authors considered the ways of expediting the determination of the kinematic viscosity ν of high temperature metallic melts. This was achieved using the parameters of the two points of the oscillatory trajectory of attenuation that differs in e times, and bipolar synchronized tightening suspended on elastic thread crucible melt. It is shown that the measurement of metallic liquids allows to analyze the materials and to make recommendations for the production of alloys with desired characteristics. The possibilities of the express-measurement with acceptable accuracy for most applications, reducing the time and experimentation to enable their standardization and reducing the impact on the experiments of subjective role of the researcher were studied. The use of two-way tightening gives a gain in time for one measurement cycle in 1.5 times, in time of twist – 4 times. The proposed approach provides an acceptable accuracy of calculations.
