The auxiliary control system for the industrial electric furnace based on is characterized in that screw holes are arranged on two sides of the first flange plate (5) and the second flange plate (6), the screw holes and the bolt holes (7) are located on the same straight line, and the fastening bolts (8) are rust-proof bolts.
4. The auxiliary control system for the industrial furnace is characterized in that the power nozzles (11) are uniformly distributed at the bottom of the fireproof roof (6), and the number of the power nozzles (11) is multiple groups.
