An electric arc is these days employed in industries and thus serve great assistance in bulk steel manufacturing. The process carried by an electric arc furnace is similar to an oxygen route as it does not implement use of hot metal.
The modern electric arc furnace carries a typical size of 150 tons and takes up a maximum time of 90 minutes to perform the expected mel
ting process. There are two types of arc furnaces namely direct and indirect arc furnaces. Direct arc furnace has three electrodes and is used to heat metal by the way of arc. On the other hand, the indirect arc furnaces take one electrode into use and works in the same way as the direct arc furnaces do.
Steel making done in this electric arc furnace is also proven to be quite inexpensive. The Arc furnace is charged with "cold" material which is known as steel scrap. If not processed, it is prone to look like unsightly as well as environmentally damaging.
The process of carrying the process in the arc furnace starts with tipping the steel scrap. This is done using an overhead crane. Following this, a lid is place over the electric arc furnace. The lid comprises of three graphite electrodes which are kept lowered in the furnace. Following this, the electric current is made to pass through the electrodes that further help in the formation of arc. The heat generated using this arc is greatly helpful in melting the scrap.
Moving ahead in the process, some other metals like (ferro-alloys) are also added to the steel to give the product to pack it in the desired chemical composition. Just with this, oxygen is passed from the electric arc furnace so as purify the steel.
