What is the function of EAF?
An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking.
What is EAF in steel plant?
An electric arc furnace is a steel making plant that melts iron sources such as scrap and direct-reduced iron (DRI) using electric energy. As electric arc furnaces use large amounts of electricity, the improvement of energy-efficiency has been a major issue in the past.
What do you mean by arc heating?
[′ärk ‚hēd·iŋ] (metallurgy) The heating of a material by the heat energy from an electric arc, which has a very high temperature and very high concentration of heat energy. Also known as electric-arc heating.
How does a submerged arc furnace work?
The SAF works with electrical energy which is converted into heat, mainly using the electrical resistance of the burden or molten slag. The electrodes are immersed in the melt which provides the required energy exchange area between electrode and melt.

What is the principle of induction furnace?
In the induction furnace, a coil carrying alternating electric current surrounds the container or chamber of metal. Eddy currents are induced in the metal (charge), the circulation of these currents producing extremely high temperatures for melting the metals and for making alloys of exact composition.
What is EAF and BOF?
There are two ways to make steel—in a Blast Furnace (BOF) or in an Electric Arc Furnace (EAF). In the U.S., approximately 75% of steel is made using the EAF method, and 25% is made by integrated mills using a basic oxygen furnace (BOF). They melt iron ore in a Blast Furnace to produce liquid iron.
What is arc furnace types?
Arc furnaces are of two types namely: (1) Direct arc furnaces. (2) Submerged arc furnaces and. (3) Indirect arc furnaces. In a direct arc furnace, shown in Fig. 5.4, the arc is formed between the electrodes and the charge, while in the indirect arc furnace the arc is formed between the electrodes, as shown in Fig.
What is saw welding process?
Submerged Arc Welding (SAW) is a joining process that involves the formation of an electric arc between a continuously fed electrode and the workpiece to be welded. It also generates a protective gas shield and a slag, all of which protects the weld zone.
