METHOD OF PRODUCING MOLTEN IRON USING ELECTRIC FURNACE CONTAINING VIDEO DEVICE Russian patent published in 2024 - IPC C21B11/10 C21C5/52 F27D13/00 F27B3/28 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used in the production of molten iron in an electric furnace, which comprises a preheating chamber, a melting chamber, an extruder located in the preheating chamber, and a video device configured to view the inside of the melting chamber. Performing the extrusion process for the cold iron raw material preheated in the preheating chamber feeding into the melting chamber by extruder, and a process of melting cold iron material supplied to the melting chamber by means of an arc and heated to obtain molten iron. In the process of extrusion, the amount of movement of the extruder and/or the time interval for movement of the extruder are controlled based on visual information received from the video device.

EFFECT: invention provides stable supply of cold iron raw material to the melting chamber and obtaining molten iron with low power consumption.
