Abstract: In a scrap metal advancing arrangement with a scrap metal pusher supported in a linear guide structure and a first hydraulic drive system comprising at least one first cylinder piston unit wherein the scrap metal pusher has a front surface extending normal to the linear guide direction, the scrap metal pusher includes an inner pusher block which is movable relative to the first hydraulic cylinder piston unit. The push block also has a front surface which extends normal to the linear guide direction, with the gradient of the effective piston surface of ail second cylinder-piston units and the effective front surface area being greater than the quotient of the effective piston surfaces of all first cylinder piston units and the effective pusher front surface area.

Abstract: In a charging hopper system of an electric arc furnace with a closure member which can be opened, a hopper-like containment with a discharge opening and at least one suction opening, the closure member closes the precharging chamber, the precharging chamber is separated from the hopper-like containment by a separating wall which can be opened and, in addition, a movable push shield is arranged in the precharging chamber for moving scrap metal from the precharging chamber into the hopper-like containment.
