註釋Almost all ferroalloys are produced by smelting in submerged arc furnaces, powered by either AC or DC sources. To understand the smelting process and furnace operations, it is important to manage the theory of electrical circuits, efficiently apply and control active and reactive parts of the system, optimize the power factor and the operation of the electric arc, and so on. These issues are outlined and discussed in this chapter, which provides necessary theoretical and practical knowledge for those who do not have a background in electrical engineering. They are complemented with discussions of heat balance and electrical control of the smelting furnaces and different emissions associated with the ferroalloys production processes.
