Synchronous/asynchronous adaptive working condition automatic control device for ultra-short net of electric melting furnace

The invention relates to the technical field of digital automatic control and automatic adjustment of equipment, in particular to a synchronous/asynchronous adaptive working condition automatic control device for an ultra-short net of an electric melting furnace. According to the device, a brake motor drives a digital speed reducer and a driving reversing fan-shaped rotating gear to rotate, and the driving reversing fan-shaped rotating gear is connected with two driven reversing fan-shaped rotating gears and enables the driven reversing fan-shaped rotating gears to rotate in a reversing mode; and each driven reversing fan-shaped rotating gear is in contact with a driven electromagnetic clutch sensor. A driven electromagnetic clutch sensor is connected with the lifting electrode rolling barrel, and a steel wire rope is wound on the lifting electrode rolling barrel through a pulley and is connected with an electrode; the other driven electromagnetic clutch sensor is connected with a lifting conductive large arm
