Then, the copper alloy raw material is poured into the interior of the melting furnace. When the liquid level of the copper alloy raw material reaches a preset threshold value of the photoelectric sensor, the buzzer is controlled to sound, thereby reminding the staff to stop pouring the raw material, and at the same time, the first electric valve and the second electric valve are controlled to close the feed pipe and the detection tube, and the first motor is controlled to stop after working for a certain period of time.

The temperature sensor detects the temperature of the melting furnace and controls the first heating furnace to produce a constant temperature to prevent the temperature in the melting furnace from being too high.

[0025] After the heating of the raw materials is completed, the stop button is pressed to control the first heating furnace, the second motor and the first vacuum fan to stop working, and at the same time, the third electric valve is controlled to open the discharge pipe channel, so that the raw materials flow into the insulation furnace through the discharge pipe. After the raw materials flow into the insulation furnace, the insulation button is pressed to control the third electric valve to close the discharge pipe channel, and at the same time, the second vacuum fan is controlled to work. The second vacuum fan extracts the hot air in the insulation furnace, so that the hot air enters the exhaust box through the third conveying pipe and the fourth conveying pipe, thereby reducing the hot air pressure in the insulation furnace.

[0026] When you want to discharge raw materials, you can control the fourth electric valve to open the discharge pipe of the insulation furnace to achieve this. When you want to discharge sewage, you can also control the fifth electric valve to open the exhaust box discharge pipe to achieve this.
