DEVICE FOR DETERMINING VISCOSITY AND ELECTRIC RESISTANCE OF MOLTEN METALS Russian patent published in 2012 - IPC G01N11/16 

FIELD: metallurgy.

SUBSTANCE: device includes main wall with console, electric furnace, melting pot with molten metal and flange with screws. Two parallel flanges with coaxial holes, indication unit of electric furnace axis position and correction unit of electric furnace axis position are introduced to the device. Indication unit of electric furnace axis position is made in the form of an assembly consisting either of elastic thread suspension fixed on the level of upper point, upper end of lead and target, at that, lower end of lead freely moves above the target, or laser level and levelling target; at that, laser level is fixed on the level of upper point of elastic thread suspension. Correction unit of electric furnace axis position is made in the form of adjustable flange with several, for example, three support adjustable screws located in circumferential direction of that flange with a pitch for example of 120 degrees. One flange is fixed on the level of flange with screws, the other flange is fixed on the level of electric furnace heating zone, holes of flanges are coaxial and located at equal distance from electric furnace axis, at least 0.3 metre.

EFFECT: shortening of preparation time period for experiment, expedition and simplification of experiments, provision of uniform and predictable heating of molten metal, and comparability of experimental results.
