For a long time, people have been hoping to unify the control cabinet, instruments and electrical devices of the whole plant from a small process section to a large one, and to control them coordinately, that is, the integration of three electricity, which is of great significance to improve production efficiency, ensure product quality and realize optimal control.

The three electric integration system with the control of heating furnace as the core mainly realizes the control of charging machine, discharging machine and heating furnace.

Automatic control system includes furnace temperature control PID loop automatic control, air gas proportion PID regulation loop automatic control, furnace pressure control PID loop automatic control and other items; thermal detection and control mainly realize combustion chamber temperature automatic control through the measurement of temperature, pressure and flow, air coal ratio automatic proportional adjustment, combustion chamber pressure automatic control, thermal detection control and other functions.
