How does an arc furnace work?

An arc furnace generates a high-intensity electric arc between two electrodes, typically carbon or graphite, producing extreme heat to melt and refine metals, such as steel, placed within the furnace.

What are arc furnaces mainly used for?

Arc furnaces are mainly used for melting and refining metals, recycling scrap, producing ferroalloys, and various metallurgical processes.

With competitive price and timely delivery, Zhongsheng sincerely hope to be your supplier and partner.

How is arc produced in an electric arc furnace?

An arc is produced in an electric arc furnace by applying a high voltage between two carbon or graphite electrodes, causing ionisation of the air or gas gap between them, which generates a conductive path and initiates the electric arc.

Where are electric arc furnaces used?

A.5. Electric arc furnaces are used in steelmaking facilities, foundries, metal recycling plants, and metallurgical processes.

What is the difference between submerged arc furnace and electric arc furnace?

A submerged arc furnace operates by immersing materials in a conductive slag bath, while an electric arc furnace uses electrical energy to create arcs between electrodes for heating.
