@@@@To solve the problem that the Muffle furnace can not heat the mineral ore due to the electric control board is damaged, the control system of the Muffle furnace is reformed. In the modified control system, the Siemens PLC is utilized as the control core, the Siemens text screen is used as the human-machine interface, the thermocouple is applied as the sensor, the thyristor trigger board is employed to shift phase to trigger the 2 unidirectional thyristors, the electric currents of the 2 unidirectional thyristors are controlled and drive the heating resistance of the Muffle furnace, and the mineral ore in the Muffle furnace is heated. The temperature control of 4 points to 8 points is implemented, and the alarms for checking the input parameter errors are established, the human-machine interface is simple. The practical operation of the Muffle furnace shows that the control system is reliable; the parameters controlled meet the desirable requirements, and the control system reformation of the Muffle furnace is succeeded.
