Electric Melting Furnace Machines

Induction furnaces are a type of electrical furnaces in which heat is generated by the induction heating of metals. Induction furnaces are utilized to melt steel, copper and a variety of other different metals that are used for jewelry. For tasks like jewelry making, one can find machines of about 1kg in weight while industrial size tools weigh up to one hundred tons.

Questions to ask before buying anelectric melting furnace 

Some key factors need to be considered prior to purchasing an electric melting furnace.

They are as follows:

• Types of alloys used and what are their melting points?
• Quantity of metal required to be melted and what is the melting point of said metal?
• How economical is the investmentfor the furnace?
• What environmental and disposal requisites need to be taken into consideration?

It is also important to have an idea of the types of furnaces used by contenders when determining which furnace to select.

Electric Arc Melting Furnace

As the name suggests, the electric arc furnace is a type of electric melting furnacein which the heatrequired to melt the metal is generated by an electric arc. This electric melting furnace issometimes used for melting steel that is reused to assemble new products. In a jewelry shop, the electric melting furnacecan be used to reuse gold and precious metal.

Crucible Furnaces

Unlike anelectric melting furnace, crucible furnaces are most often built using obstinate substances such as ceramics as they show resistance to extreme heat conditions. The crucible or as some would say, the cauldron, is subjected to extreme heat, melting all components including steel in the process. Whether it be size, design or heating system all crucibles vary from one another. There are a number of different crucible furnaces such as movable furnaces, fixed furnaces, and tilted furnaces.

The primary advantages of a crucible furnace over an electric melting furnaceis its relatively low investment charges along with the simple operation and maintenance procedures. Nevertheless, it is important to know that crucible furnaces are no longer considered economical for melting large volumes of metal as the energy consumption increases drastically and the process itself is time consuming.

How does an electric furnace for melting metal work? 

As the name suggests, an electric furnace for melting metalcan attain the required melting temperature with the use of induction technology, using alternating electrical currents. On top of their energy efficiency, easiness to operate and high quality, the machine’s ability to melt small volumes less than 1kg to larger volumes up to 100 tons have led to many manufactures opting to use electric furnaces.

An electric furnace for melting metal consists of an inductor that transfers the energy into molten ore or material. The inductor, which is most often a cooled coil, is modified and manufactured to befit each furnace shape and model. This inductor is most often located exterior to the crucible.

Uses for a mini electric melting furnace

The volume capacities of a mini electric melting furnaceare most often used to melt steel, copper, aluminium and other exquisite metals for use in the jeweler’s workshop. A mini electric melting furnace is often cost cheaper and has a smaller physical footprint.

Small electric silver melting furnace

Melting silver becomes less complicated as you learn the fundamentals of each metal’s melting points. It’s relatively low melting point has led to many jewelers opting to use silver as a starting point in understanding the fundamentals.

Can melt gold with an electric furnace for gold melting Electric melting furnaces are able to melt metals like gold. You can also find specific gold melting equipment to get the job done.

Tips on using anelectric silver melting furnace

Start off by tying back loose hair and clothing. Ensure the silver is dry prior to melting in the electric silver melting furnace order to avoid splatter. Afterwards, pour the melted copper into the metal casting with haste – otherwise, the silver may solidify inside the crucible.

Copper melting furnace

Copper jewelry is considered extremely high value due its one-of-a-kind burned “red” shade and the belief among holistic healers of its ability to cure arthritis among a number of other healing properties.

Copper has an extremely distinctive bright reddish color along with a soft and malleable texture. Although copper shows extremely good thermal and electrical conductivity, allowing it to melt without much difficulty, it has a high melting point that reaches 1,083 degrees Celsius or 1,982 degrees Fahrenheit.

As always, as this involves working conditions with extremely high temperatures, it is important to take safety precautions, work with extreme caution and make sure you’re always equipped with your safety gloves and face protection mask!
