METHOD AND APPARATUS FOR DETERMINING SURFACE TENSION AND/OR DENSITY OF MOLTEN METAL Russian patent published in 2015 - IPC G01N9/00 

FIELD: chemistry.

SUBSTANCE: method of determining surface tension and/or density of molten metal, which employs photometry of a resting large droplet, wherein during analysis, solid samples are loaded into the heating area of a horizontal-type electric furnace, after which each of the loaded solid samples is analysed. Each solid sample is placed on a separate substrate. Said substrates with the solid samples are loaded into the heating area of the horizontal-type electric furnace simultaneously, followed by simultaneous analysis of all the samples. An apparatus for determining surface tension and/or density of molten metal comprises a horizontal-type electric furnace with an area for heating solid samples under analysis, a device for simultaneously placing multiple solid samples thereon and a rod for moving the solid samples into the heating area. The device is configured to move into the heating area of said electric furnace and the rod is configured to move into the heating area of said device, which is designed to simultaneously place multiple samples thereon.

EFFECT: high efficiency of analysis, broader functional capabilities of determining surface tension or density by simultaneously obtaining and synchronously comparing parameters of the samples under analysis, shorter experiments and low power consumption.
