I want to melt copper myself. What should I do?

Induction furnaces can be used to heat and melt copper.

Induction furnace is a melting furnace which uses the heat generated by current induction to heat and melt iron. The structure of the furnace can be divided into two types: cored and coreless.

In the coreless induction furnace, the iron in the crucible generates induced current under the action of alternating magnetic field, thus generating heat, melting itself and overheating the molten iron.

In the cored induction furnace, molten iron from other furnaces needs to be added. The alternating magnetic field generated in the annular iron core will overheat the molten iron in the groove, and the molten iron in the groove and the molten pool above are used to heat all the molten iron.

Coreless induction furnace has the ability to melt solid charge, while cored induction furnace can only overheat molten iron, but in terms of electric energy consumption of overheated molten iron, cored induction furnace is more economical.

Extended data:

Please pay attention to the following points when using:

(1) Before starting operation, observe the voltage value of the power supply and the balance of the three-phase power supply;

(2) Carefully check the connection of electrical contacts, especially SCR chimney, electrothermal capacitor and water-cooled electricity.

Cables, etc.

(3) Start the cooling circulating water system, check the waterway operation of the main engine and the furnace body, and maintain a certain water pressure;

(4) In order to reduce the erosion of the furnace lining by electromagnetic stirring in the sintering and baking process of the furnace lining, it is necessary to run at low power for a period of time (reduce the voltage) to make the furnace body heat up evenly;

(5) In normal operation, check the operation of the equipment, especially the water temperature of each branch. If we have experience, we can also judge whether the equipment is normal by the change of sound;

(6) When the electric furnace stops, the cooling water can be appropriately reduced, but the cooling water cannot be turned off, otherwise the residual heat of the furnace lining will burn out the coil and insulation layer.
