FIELD: physics.
SUBSTANCE: method is meant for contactless measurement of viscosity and electrical resistance of high-temperature molten metal. Viscosity is measured via photometric determination of parameters of torsional vibrations of a cylindrical crucible with the melt. Disclosed is a crucible device, having a crucible, a disc, a carrying cup suspended on an elastic thread in the high-temperature zone of an electric furnace, placed inside the crucible in which guide elements are introduced, fixed on the cover and inserted into corresponding holes in the disc. The guide elements are in form of tubes which link the top surface of the melt and the space over the crucible outside the crucible device and lie symmetrically about the axis of the crucible.
EFFECT: high reliability and accuracy of determining parameters of high-temperature molten metal, eg, kinematic viscosity values.
