First, technical specifications and requirements:

Melted material: scrap copper .

Melting: melting temperature of 1300 degrees, the melting time of 50-60 minutes in a furnace.

crucible: silicon carbide

Second, technical solutions and equipment selection

According to the technical requirements of the purchaser, an intermediate frequency induction melting furnace can be selected. The process is as follows:

The metal material is manually placed in the crucible of the dumping furnace .

After the metal is melted into a liquid, the furnace body is electrically controlled and the liquid is poured into the mold.    

Third, the picture reference description: IF power supply + compensation capacitor + electric dumping furnace

Fourth, the technology selection of scrap copper melting furnace

Five, waste copper melting furnace configuration:

Customer- installed machine accessories ( circulating cooling system ) :

1. Three-phase air switch 400A 1 ;

2. Power connection soft cable 90 mm2 several meters;

3 . Cooling tower 30 tons 1;

4. Pump 3.0kw/ head 30-50 meters 1 set ;

5 , equipment inlet and outlet water pipes: high pressure enhanced water pipe outer diameter 16 mm, inner diameter 12 mm several meters

6. Water pump inlet and outlet water pipe: 1 inch (inner diameter 25 mm) with wire high pressure reinforced pipe several meters

Seven, the use of waste copper melting furnace operation steps :

1, electrical connection: access to a dedicated power supply line, respectively, three-phase air switch. Then connect the ground wire. ( Note that the three-phase electric power should be able to meet the use of the equipment, and the wire thickness should be used according to the instructions )

2 , water: (depending on continuous working time and workload) select the cooling water system to achieve water circulation cooling.

3 , water: open the waterway, and check the water outlet of each device to see if there is water outflow, whether the flow and pressure are normal .

4, power: the power switch to open the control, followed by a switch to open the air behind the machine, and then turn the power switch on the control panel.  

5 , start: Before the first furnace starts, the heating power potentiometer should be adjusted to the minimum as much as possible, and then slowly adjusted to the required power after starting. Press the start button to start the machine. At this time, the heating indicator on the panel lights up, and the prompt sound of normal operation and the work light flash simultaneously. 
6. Observation and temperature measurement: In the heating process, it is mainly determined by visual inspection when to stop heating.

7. Shutdown: Shutdown, the control device switches off first, then turn off the main power external switch, then delayed until about 1 hour after the furnace temperature down; then off equipment cooling water, the heat inside the machine to facilitate the induction loop and the heat distributing . 
8. In areas where it is easy to freeze in winter , it should be noted that after each use, compressed air should be used to blow out the water in and out of the equipment to prevent internal cracking of internal fittings and water pipes.

Nine, can the molten copper use the medium frequency induction furnace?

The copper melting furnace can choose medium-frequency copper melting furnace, and the small energy-saving molten copper has a good quality melting of 150KG~~500KG capacity.

If you choose to use a steel shell energy-saving copper melting furnace, the energy saving rate will increase by about 10% . The price is very high and the advantages are obvious.

Fused copper, molten zinc, and molten aluminum are suitable for medium frequency induction furnaces, intermediate frequency furnaces for melting copper and copper alloys .
