Abstract:

There is a unit proposed for investigations in the high-temperature metallic liquid alloys, using image photometry of a “large melt drop” resting on the horizontal backplate. The unit is designed to determine the density d and surface tension σ of a sample of the mass given, placed into a horizontal electric furnace. Using a volumenometer enables measuring the geometric parameters of the drop. Various ways of expanding the range of operational functions are presented, in particular, extending the temperature range Δt° and improving the unit efficiency as well as decreasing the artifacts’ impact. Updating the unit enables the studies (including the comparison studies) of both luminous and nonluminous samples to be conducted combining various ways of illuminating both the melt drop’s contours and surface. The ways of reducing the influence of vibrations and refining the backplate’s horizontal position as well as the possible measures for partial cleaning the films from the drop surface of the multicomponent melt are proposed. The use of the unit updated on the basis of approaches developed and patented by the authors enables reducing the time to be spent on measurements, expanding the range of the unit’s operational functions, decreasing the artifacts’ impact and improving the validity of the results obtained. © 2017 Trans Tech Publications, Switzerland.
