To facilitate a trouble-free charging of scrap metal having differing constitution such as light and heavy scrap metal, from a lower discharge opening of a shaft-shaped charging device (1) into a melting vessel by a pusher (13), the lateral surface of the pusher (13) are formed so as to converge from the upper side to the lower side and the actuating device (2) of the pusher (13) is pivotably supported in a frame structure (3) about a horizontal axis. In addition, the upper boundary of the discharge opening for the charging stock from the shaft (2) is formed by a horizontal, rotatably supported roller (26), preferably with engaging elements (30) distributed on the circumferential surface. Sections of the charging, device that are severely mechanically stressed are formed by steel billet sections connected to form a structural unit. Preferably, the charging device is formed as a charging stock pre-heater.
