FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and is intended to measure slag thickness on liquid metal surface. Device contains wire made from electrically conducting material, which can be melted under effect of heat at slag temperature, wherein wire has free end designed for immersion into slag. Device also comprises wire feed facilities, making it possible to move wire so, that its free end is vertically immersed into slag in accordance with preset trajectory. There is also measuring device to measure distance, which wire free end passes in period of time when wire is moved under action of supply device, and supply control device, wherein control device includes detector to detect contact between free end of wire and liquid metal surface.
EFFECT: technical result is higher measurement accuracy.
