Abstract

The invention provides a measuring device for measuring surface tension of high-temperature melt by adopting a hanging drop method. The measuring device comprises: a heating furnace used for melting a solid sample into a liquid; a hanging drop forming device arranged in the heating furnace and used for containing the sample and forming a melt hanging drop; a motor control device used for controlling the melt hanging drop; an image shooting device used for observing and shooting the melt hanging drop; and a computer used for processing and calculating the shot hanging drop image to obtain the surface tension of the sample. The measuring device adopts the hanging drop method to calculate the surface tension of the high-temperature melt, the measurement accuracy of the surface tension is greatly improved, the operation is simple, and the data is reliable. The measurement process can be detected and controlled in real time, and the method can be widely used for measuring and researching the surface tension of the high-temperature melt.

Description

technical field [0001] The invention belongs to the technical field of melt physical property measurement, and relates to a measuring device for measuring the surface tension of high-temperature melt by a pendant drop method. Background technique [0002] Surface tension is an important parameter of liquid physical and chemical properties, and one of the key factors affecting the interphase mass transfer and reaction of multiphase systems. As well as the interfacial properties between them, they play a leading role in the reaction and separation between melts, and are also the basis for studying the kinetics of melt interface reactions. [0003] For high-temperature melts such as liquid metal, slag, molten salt, and smelt, due to the high temperature above 1000 degrees Celsius, the difficulty and complexity of the measurement are increased. The measurement methods applied to the surface tension of high-temperature melts mainly include the maximum bubble method. , Electromag...
