Abstract

Régulation du moulage d'un métal dans un moule alimenté par dessous par une pompe électromagnétique, avec une phase de remplissage à tension croissante, puis formation de peau à tension constante, puis solidification à tension accrue et solidification à tension de repos. On utilise des mesures de température du moule et du métal dans le four pour régler la durée des deux premières phases, dans le sens une réduction de durée pour une diminution de température. On utilise aussi la mesure de température du moule pour régler dans le même sens la durée de la quatrième phase. L'invention s'applique à la coulée basse pression des alliages d'aluminium.
