Refining furnace smelting temperature control method and device for aluminum bar production

The invention discloses a refining furnace smelting temperature control method and device for aluminum bar production. The refining furnace smelting temperature control device comprises a base, an electromagnetic heater and a furnace body, the electromagnetic heater is installed in the middle of the upper end of the base, and a control cabinet is installed on one side of the upper end of the base. The method and the device have the beneficial effects that through the design of an infrared thermometer, a circulating groove, a water inlet pipe, a water drainage pipe and a water drainage electromagnetic valve, a refining furnace can have the automatic temperature control and waste heat recovery functions, the refining furnace can recycle waste heat generated during automatic temperature balance, and thus the practicability of the refining furnace is improved; through the design of a PLC, a photoelectric sensor, a material discharging pipe and a material discharging electromagnetic valve, the refining furnace can
