Electric arc furnace Wikipedia

An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc.. Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.Arc furnaces used in research laboratories and by dentists may have a capacity of only a few

Electric Arc Furnace Process an overview ScienceDirect

In the electric arc furnace process, the electric arc furnace oxidizing slag is firstly produced when the iron scrap is melted and refined into steel, and then the electric arc furnace reducing slag is produced in the ladle refining furnace. Further refining of the stainless steel in the ladle furnace generates argon oxygen decarburization slag

Understanding Electric Arc Furnace Steel Making Operations

Electric arc furnaces range in capacity from a few tons to as many as 400 tons, and a steel melting shop can have a single furnace or up to three or four. In brief, these furnaces melt steel by applying an AC current to a steel scrap charge by mean of graphite electrodes. It requires a tremendous quantity of electricity.

Electric Arc Furnace: Most Efficient Technologies for

Jul 19, 2019· In the electric arc furnace, steel is produced only through scrap fusion. Scraps, direct reduced iron, pig iron, and additives are melted through high-power electric arcs formed between a cathode and the anodes. The emissions levels are normally mainly related to the indirect emissions due to the high energy consumption of the process.

Electrical Arc Furnace : 7 Steps (with Pictures

An electric arc furnace is a type of furnace that heats up materials using a very high current. The rods (which are made of graphite for its semi-conductive properties) heat up and create a plasma that can be directed to melt metals. Although electrical arc furnaces (EAFs) are reliant on large amounts of electricity, it is fairly cheap and in

On the Advantage and Disadvantage of Electric Arc Furnace

As electric furnaces that use electricity as heat energy, they can be divided into two categories, one is an electric arc furnace, which is used to generate heat by arc to melt scrap steel, and the other is an induction electric furnace, which generates heat by electromagnetic induction to melt scrap steel, especially in medium frequency induction.
