6 Best Propane Melting Furnace Smelting Furnaces 2023

Why An Electric Melting Furnace?

Are you worried about greenhouse gas emissions caused by non-electric melting furnaces? Well, then going electric is the best solution. Electric furnaces replace unit processes that use fossil energy with electricity in smelting.

Worth Knowing; Types of Electric Melting Furnaces

Among the key parameters you should consider when choosing the right electric melting furnace is the type or kind. Below are the common and popular types of electric metal foundry elaborated:

Induction Furnaces

This type of electric melting furnace uses an electric charge to produce induction, producing a magnetic field. It is the vibrations that are caused by the electromagnetic field that cause the target metal to be molten. One advantage of this electric melting furnace is that you can melt all types of metals or metal alloys.

Cupola Furnaces

These are one of the best large scales casting furnace. They are popularly used for melting cast irons. The constituents of the Cupola electric melting furnaces are; coke, limestone, metal parts, and other alloying elements. Utilizing a charge inside a large cylinder coated with a refractory liner, the electric cupola furnaces are one of the most effective if you think of going large scale.

Crucible Furnaces

The crucible electric melting furnaces are popularly used for melting metals that are non-ferrous alloys. This is because such metals require low melting temperatures. The melting pots of the crucible furnaces are made from refractory materials. The crucible furnaces use burning fuel to heat the melting pot centrally placed in the crucible. Coal and natural gas are common fuel types used in crucible furnaces.

There are three variations of crucible furnaces that are worthwhile knowing. They include;

The stationary pot crucible furnaces

This has the pot being stationary in the furnace. There is a tap installed at the bottom of the furnace. The tap is used to drain the molten metal from the stationary pot.

Lift-out pot crucible furnace

With the help of cranes at the manufacturing site, the pot is lifted after the metal is fully molted. The molten metal is then served to the molds for further processing.

Tilting pot furnace

The furnace system is tilted when pouring the molten metal hence the name tilting pot furnace. However, it is good to note that the pot is stationary inside the crucible furnace. All other parameters for this particular type of furnace are the same.

The Electric Arc Furnaces

These are among the most influential electric furnaces as they can melt metal up to 45 tonnes per hour. Electric arc furnaces are best-used foundries with a need for large mass production of molten metals. They are very easy to operate as the working principle of the arc electric melting furnaces is very simple.

An electric current is used to produce heat and an electric arc. The heat is then used to melt the metal most swiftly and effectively. However, it is best to note that with this kind of electric melting furnace, you will have to incur high energy consumption compared to other methods.

If you want to make the most out of metal scraps on whichever scale, then you need to be conversant with the metal melting furnace trends. The metal melting furnaces can be electrical or non-electrical. Melting metals can be a dangerous and tricky affair; hence you need to choose the best melting furnace to be safe and efficient in your work.

This article gives you a collection of the best options to choose from based on the qualities of the melting furnace. Stick and read entirely to make not only a formed but an informed decision on your next melting furnace.

What are the types of melting furnaces?

Furnaces can be electrical or non-electric energy sourced. Four types of furnaces are the cupola furnace, induction, and open-hearth furnace.

Which furnace is the best to melt scrap?

Furnaces can be rated based on price, energy convenience, or even design. However, based on ratings and reviews from most customers, the induction furnaces are considered the best of their peers. This has also been proved over time by experts.

How is metal melted?

Metals have a higher melting temperature than other materials and can change their forms when heated up – unlike wood which only decomposes. The metal’s ions vibrate when temperatures rise enough to break the bonds they have with each other and allow them to move freely.

Fluid is formed when the metal’s internal structure shifts and its bonds become looser. The melting point of a metal is determined by the strength of its bond, which is determined by the material. Metal alloys may have different melting points than individual metals, so they might not melt as smoothly.
