in Syracuse, New York, installing the first electric arc furnace in the U.S. The Sanderson brothers formed The Sanderson Brothers Steel Co. įurther electric arc furnaces were developed by Paul Héroult, of France, with a commercial plant established in the United States in 1907. This was specifically for the creation of phosphorus. The first successful and operational furnace was invented by James Burgess Readman in Edinburgh, Scotland, in 1888 and patented in 1889. Sir Humphry Davy conducted an experimental demonstration in 1810 welding was investigated by Pepys in 1815 Pinchon attempted to create an electrothermic furnace in 1853 and, in 1878–79, Sir William Siemens took out patents for electric furnaces of the arc type. In the 19th century, a number of people had employed an electric arc to melt iron. History Stassano furnace exhibited at the Museo della Scienza e della Tecnologia "Leonardo da Vinci", Milan In electric arc furnaces, the charged material (the material entered into the furnace for heating, not to be confused with electric charge) is directly exposed to an electric arc, and the current from the furnace terminals passes through the charged material.Īrc furnaces differ from induction furnaces, in which the charge is heated instead by eddy currents. Industrial electric arc furnace temperatures can reach 1,800 ☌ (3,300 ☏), while laboratory units can exceed 3,000 ☌ (5,400 ☏). Arc furnaces used in research laboratories and by dentists may have a capacity of only a few dozen grams. 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. Type of furnace An electric arc furnace (the large cylinder) being tapped Rendering of exterior and interior of an electric arc furnace.Īn electric arc furnace ( EAF) is a furnace that heats material by means of an electric arc.
