What is the melting furnace?

furnace melting is a type of tool used to heat materials, usually for industrial application. In general, they differ in terms of materials that can heat, temperatures that can generate, and how they work. Some of the most common types are dome furnaces, electric arc furnaces, induction furnaces and crucible furnaces.

Pec used people for a very long time. It is assumed that the earliest furnace was created by the civilization of the Indus Valley Indian subcontinent and was dated somewhere between 2500 and 1800 BC. Melting is an industrial version of this concept and is usually used to produce specific materials or as a source of heat.

Some industrial scientists consider the dome furnace the most popular form of melting furnace for iron materials. This device consists of a vertical shaft furnace, reminiscent of a smoker. The interior is usually lined with refractors. Inside the shaft can also be found air nozzles that are used to increase heat. Kupol furnace can be used for different tasks, such as the production of liquid ore and melting cast iron or bronze.

Electric arc furnaces are usually used to melt steel scrap. Smaller units can also be used for the production of cast iron products. As the name suggests, this model uses an electric arc to generate heat. The arch creates an electrical gas distribution that causes a plasma discharge. Inside the furnace unit, the material is in direct contact with the arch, which in some units can reach temperatures of up to 3275 ° Fahrenheit (1800 ° Celsius).

Induction furnace is generally used for melting both iron and non -ferrous alloys. Usually uses a water -cooled, copper spiral coil in which a crucible is installed. When the alternating current passes through the coil, the crucible is heated. This model is generally appreciated for its energy efficiency and lack of pollution it causes. Most iron foundry now uses InduKniční furnace instead of dome furnace due to these advantages.

Beautiful furnace is considered the oldest type of melting. Its basic design consists of a refractory crucible in which the material to be heated is to be heated. The material is then heated from the outside of the crucible. The gas versions of this often use a burner to generate heat, while electric models use heating elements.
