Electric Arc Furnace at a Factory (5-Clip Pack) (Stock Footage)

An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. An electric arc furnace used for steelmaking consists of a refractory-lined vessel, usually water-cooled in larger sizes, covered with a retractable roof, and through which one or more graphite electrodes enter the furnace. The furnace is primarily split into three sections: - the shell, which consists of the sidewalls and lower steel “bowl”; - the hearth, which consists of the refractory that lines the lower bowl; - the roof, which may be refractory-lined or water-cooled, and can be shaped as a section of a sphere, or as a frustum (conical section). The roof also supports the refractory delta in its centre, through which one or more graphite electrodes enter.
