An arc furnace is a type of electric furnace that uses an electric arc to melt and refine metals. It consists of large electrodes that create a high-temperature arc when electricity passes through them, generating heat. This process is commonly used in the production of steel and other alloys, allowing for efficient melting of scrap metal and other materials. Arc furnaces are known for their ability to quickly reach high temperatures and their flexibility in handling various types of raw materials. They are an essential part of modern metallurgy, contributing to the recycling of metals and reducing the environmental impact of metal production.
