Advantages of Electric Arc Furnace for Steelmaking
The electric arc furnace is mostly accepted by steel making companies, thus a large quantity of graphite electrode are consumed. Why is that? The first benefit is that the use of electric arc furnace allows steel to be made from a 100% scrap metal feedstock. This greatly reduces the energy required to make steel when compared with primary steelmaking from ores.
Another benefit is flexibility: while blast furnaces cannot vary their production by much and can remain in operation for years at a time, EAFs can be rapidly started and stopped, allowing the steel mill to vary production according to demand. Although steelmaking arc furnaces generally use scrap steel as their primary feedstock, if hot metal from a blast furnace or direct-reduced iron is available economically, these can also be used as furnace feed. As EAFs require large quantities of electrical power, many companies schedule their operations to take advantage of off peak electricity pricing.
