What Is Submerged Electric Arc Furnaces?
Submerged electric arc furnaces (SAF) is an industrial piece of equipment used to produce a variety of metals, primarily steel. These furnaces use an electric arc to generate heat and melt raw materials submerged in a bath of liquid metal. This process offers several advantages over traditional electric arc furnaces, making it a popular choice in the steel industry. What Is Submerged Electric Arc Furnaces? Principle of submerged arc furnace A submerged arc furnaces consists of a vessel lined with refractory material, usually cylindrical in shape. The furnace is filled with a conductive liquid, usually a mixture of molten metal or slag, which serves as an electrical connection to the graphite electrodes. Electrodes are introduced into the furnace from the top and provide the arc required for melting. Advantage One of the main advantages of submersible furnaces is their high energy efficiency. Using a thermal fluid bath significantly reduces heat loss compared to other types of furnaces.
