Melt-Level Sensor and Its Application to Investigation of Radiant Heat Exchange in an Electroslag-Remelting Unit

A light-guide transducer has been developed and experimental investigations of the distinctive features of radiant heat exchange between the smelting zone and the wall of the crystallizer of an electroslag-remelting unit have been carried out. A relation making it possible to determine the slag or metal temperature has been obtained. A method of measurement and the structure of a sensor of liquid-metal level have been developed; its operating characteristics have been investigated.
