Abstract

En un método para preparar una suspensión de una aleación semisolidificada, donde la aleación primeramente se encuentra presente en forma líquida y a continuación es enfriada para ser conducida hacia el dispositivo de conformación (6-8) se cumple por lo menos una de las siguientes combinaciones de características: a) que el tiempo de residencia en la trayectoria de suspensión (9) se seleccione de tal manera que la proporción de fases deseada se logre la trayectoria de suspensión (9) por lo menos aproximadamente dentro del tiempo del ciclo de la máquina conformadora; b) que en la trayectoria de suspensión (9) se extraiga por lo menos 20% del calor de la fusión, indicada como índice de entalpía en kJ/mol y/o c) que la aleación líquida sea dirigida continuamente, mientras se distribuye primeramente una primera cantidad de gérmenes en el volumen de la fusión, a un segundo paso de formación de gérmenes en una corriente turbulenta con extracción de calor y que en un tercer paso la suspensión de la aleación semisolidificada así obtenida sea llevada a un dispositivo de conformación (1, 16 20). Un dispositivo para llevar a la práctica el método presenta ventajosamente un depósito de reserva (9') para aleación líquida y una trayectoria de suspensión en serie, que tiene una trayectoria de suspensión (9) que va desde una entrada a una salida. En el depósito de reserva (9') se encuentra un dispositivo de distribución y avance (17) para avanzar un volumen de fusión en forma por lo menos periódicamente continua por la trayectoria de suspensión (9). También resulta ventajoso que la trayectoria de suspensión (9) tenga por lo menos una superficie conductora de la fusión o por lo menos una superficie de fondo que se extienda a lo largo y que esta superficie o fondo sea de un material que no se impregna con la suspensión de la aleación.In a method for preparing a suspension of a semi-solidified alloy, where the alloy is first present in liquid form and then cooled to be conducted towards the forming device (6-8) at least one of the following combinations of characteristics: a) that the residence time in the suspension path (9) is selected in such a way that the desired phase proportion is achieved in the suspension path (9) at least approximately within the cycle time of the forming machine ; b) that in the suspension path (9) at least 20% of the heat of the fusion is extracted, indicated as enthalpy index in kJ / mol and / oc) that the liquid alloy is continuously directed, while first distributing a first quantity of germs in the volume of the fusion, to a second step of germ formation in a turbulent stream with heat extraction and that in a third step the suspension of the semi-solidified alloy thus obtained is taken to a forming device (1 , 16 20). A device for carrying out the method advantageously has a reserve tank (9 ') for liquid alloy and a series suspension path, which has a suspension path (9) that goes from an entrance to an exit. In the reserve tank (9 ') there is a distribution and feed device (17) for advancing a melting volume at least periodically continuously along the suspension path (9). It is also advantageous that the suspension path (9) has at least one conductive surface of the fusion or at least one bottom surface that extends along and that this surface or bottom is of a material that is not impregnated with The alloy suspension.
