摘要： Loading system for an electric arc furnace (11) includes a loading station (20a), a pre-heating station (20b) and a pick-up and moving device (15) provided with an arm (17) rotating on a circumference on which the furnace (11), the loading station (20a) and the pre-heating station (20b) lie. The loading station (20a) being distanced from the pre-heating station (20b), the loading element (16) being suitable to be located in or removed from each of the loading (20a) and pre-heating (20b) stations. The manipulator arm (17) also is suitable to be moved vertically to move the loading element (16) between the loading station (20a), the pre-heating station (20b) and a position above the furnace (11), in the pre-heating station (20b) the container (12, 112, 212) being suitable to cooperate with the air-tight cover (23) and at the lower part with a combustion chamber (21) The air-tight cover (23) is movable both vertically and rotatably on a horizontal plane, the fume-discharge conduit (22) being at least partly coaxial with the axis of rotation of the air-tight cover (23).
