FIELD: metallurgy.
SUBSTANCE: device for control of temperature and level of melt in electric arc furnace consists of thermal imager with program block signal processing. Also, the device consists of one or more sensors in form of rods made out of refractory material and passed through heat insulating material-packing through lining and case of a furnace. One end of the rods directly contacts melt in the furnace, while another end is communicated with input of the thermal imager.
EFFECT: reduced power expenditures and raised quality of finished melt.
