Casting Furnace

What is a casting furnace?

Casting furnaces are devices that can melt metals or alloys quickly and at an affordable cost with specific weight and heat.

Types of casting furnaces differ in cost, quality of metal and alloy, each of which can increase or decrease the price of casting furnaces.

What are the types of casting furnaces?

There are different types of casting furnaces and each one has its own method and function. The main purpose of all casting furnaces is to generate the necessary heat to melt metal or alloys.

·         Bush furnace

Among the types of industrial furnaces, we can mention the bush furnace, which is one of the most common types of casting furnaces and has been active in this industry since the past. In addition, bush furnaces are among the most important forms of metal furnaces that can withstand high temperatures.

· Induction Furnace

Another type of industrial furnace is induction furnace. The heat and temperature required for these induction furnaces is done through electromagnetic current induction technology. The source of electromagnetic transmission is the copper coils that surround the part but do not have contact with it. Similarly, with the transfer of electromagnetic current, the direction of its field is also changed.

This process is repeated several times until the metal molecules inside it move and finally it ends up producing heat and the metal slowly turns into a liquid. As we said, there is no direct relationship between the metal and the melting tool, so it is possible to control the activity of the metal and produce the necessary compounds with the best quality.

·         Electric arc furnace

Among the casting furnaces, the biggest one is the electric arc furnace, which can melt large amounts of metals up to 45 tons.

·         Radiation furnace

Other types of furnaces include radiation furnaces. The working process of this furnace is that the heat is transferred in the form of a stream from the surface of the charge and due to the radiation of the flame, the charge becomes liquid. In these types of furnaces, heat moves and melts based on radiation.

In these furnaces, air and energy enter the furnace chamber from one side using a burner. By burning, heat energy is provided to melt the charge. The energy consumed by these furnaces can be liquid, gas or solid. The capacity of radiation furnaces is about 15 to 75 tons. Of course, in small radiation furnaces, this amount has a capacity of less than 500 kg. Radiation furnaces are used to produce copper, tin and aluminum.

·         Copela furnace

A cupella furnace is a cylindrical furnace with fireproof walls. Cupella furnaces are completed using coke and coal and additives, and metals are added to the furnace while it is hot. These types of furnaces are very simple and cheap, and all kinds of metals can be melted in it. Similarly, the cupola furnace plays a role in removing iron slag and can produce the best cast iron after ground furnaces.
