Copper is a transitional metal, which means that it is a good conductor of electricity and heat. This makes it particularly valuable for construction, wire, piping and many other commonly used items. It is easily melted down to form whatever shape the user needs. This article will explain in brief the process of melting copper, and why an induction furnace is the ideal means for doing so.
Melting the Copper
Copper melts at 1981.4 degrees Fahrenheit or 1083 degrees Celsius. The question of how to melt copper is a straightforward one. You will need a furnace capable of heating the metal to higher than that temperature, and sustaining the heat.
Load your scrap copper into the crucible (furnace) and turn on the furnace. Once you reach the melting point, maintain the temperature at a stable level until all of the copper has liquefied. An induction furnace maintains heat at a stable level better than other kinds of furnaces and can deliver a smoother and more stable production, meaning your final product will be stronger.
There will likely be dross on the surface formed from mineral waste, on the top. This dross must be skimmed off from the surface to ensure that your copper is as pure as it can possibly be.
Removing Copper from Furnace
The final step is to remove the copper from heat and transfer it to molds or other shaping equipment. This has to be done quickly as the molten copper will harden once removed from heat, and can ruin the crucible. Use tongs or tilt the furnace to transfer the molten metal to the mold.
With advance induction furnace, which can deliver anywhere from 60-75% efficiency, is clean, and offers uniformity and purity in the final delivery, is an ideal means of melting copper.
Induction Furnaces and Copper Melting
While there are many furnaces capable of reaching the melting point of copper, an induction melting system is ideal means of melting copper, because these furnaces use an electric coil at a low voltage and high current to transfer heat energy in an efficient and easily controllable manner. Induction melting is advance melting process and it more safe than other melting process.
