    Abstract: Procédé de fusion de scrap en alliage d'aluminium contenant du lithium dans lequel (i) on approvisionne du scrap contenant des alliages de type aluminium-lithium (étape d'approvisionnement) ; (ii) on prépare un lit initial de métal liquide d'une première composition (étape de préparation du lit initial de métal liquide) dans un four de fusion ; (iii) on charge ledit scrap sur ledit lit initial de métal liquide de façon à créer à la surface dudit lit de métal liquide un matelas flottant d'épaisseur contrôlée dudit scrap (étape de chargement), ledit matelas fondant partiellement au contact dudit lit de métal liquide de façon à obtenir un bain de métal liquide d'une seconde composition pouvant être égale ou différente de la première composition , la teneur en lithium dudit bain de métal liquide d'une seconde composition étant comprise entre 0,1% et préférentiellement 0,2% à 2,5% en poids ; (iv) on prélève le métal liquide (étape de prélèvement) dudit bain de métal liquide d'une seconde composition. Le procédé selon l'invention présente des avantages techniques et économiques : - il ne nécessite pas d'investir dans une installation particulière, notamment à atmosphère inerte, - il ne nécessite pas, ou il minimise l'utilisation de consommables onéreux tels que du gaz inerte, car la formation d'un matelas de scrap d'épaisseur contrôlée permet de protéger de l'oxydation la surface du métal liquide d'une façon étonnement efficace.

    Abstract: A device for liquid pumping comprises a pump chamber (21) arranged to receive a subportion of the liquid to be pumped. The pump chamber is provided with means for cyclic variation of the pressure in the pump chamber between an overpressure and a depression with regard to the pressure in the chamber (17) where the main portion of the liquid is. The pump chamber (21) is further provided with an input opening (22) and an output opening (23). The input opening (22) has a substantially lower flow resistance in the direction into the pump chamber (21) than in the opposite direction, and the output opening (23) has a substantially lower flow resistance in the direction out of the pump chamber than in the opposite direction, so that with a depression in the pump chamber a larger liquid quantity is sucked into the pump chamber through the input opening (22) than through the output opening (23) and that with an overpressure in the pump chamber a larger liquid quantity is forced out through the ouput opening (23) than through the input opening (22). Due to this fact a net liquid quantity can be sucked in through the input opening and forced out through the output opening. The device makes it possible to pump many types of liquids, for example molten metal, without the use of movable valves.

    Abstract: The scrap that is to be charged into an electric arc furnace (11) is preheated by a gas in a closed circuit (21, 20, 23, 22, 17) and this gas is heated in a heat exchanger (17) by the exhaust fumes from the furnace. A minor part of the circulating gas is continuously led off to a burner (25) in which it is burnt with a gas as fuel at such a high temperature that rest products such as dioxines are destroyed. The exhaust fumes from the burner (25) is supplied to the exhaust fumes of the furnace (11) upstream of the heat exchanger (17). In another burner (27), another minor part of the circulating gas is continuously burnt with a gas fuel at a substantially lower temperature so that hydrocarbons in the circulating gas burn. The exhaust fumes from the burner (27) are returned to the closed circuit.

    Abstract: The facility is designed to win metals, for instance zinc, from metal wastes and can be successfully used in industry. The facility represents an inclined casing faced inside with a heat insulating material and provided with mounted interchangeable reflectors made of bead-formed metal sheets. Onto a cantilever-supported casing shaft is set up a removable drum with a cross-shaped stiffening member inside. Solid wastes can be charged into the drum directly on the areas of formation and disposal of waste, still they can also be charged without removing the drum from upon the casing shaft through the open cover. Soot is taken away from the drum through the open cover, too. The facility has a temperature sensor and an automatic operating conditions control unit; while rotating, the drum is heated by means of a burner. Availability of a good heat insulation of the casing and that of an outlet pipe for ordered removal of combustion products makes the production process ecofriendly.
