Title
(EN) PRODUCTION OF FOUNDRY PREMIX COMPOSITION
(FR) PRODUCTION D'UNE COMPOSITION DE PRÉMÉLANGE DE FONDERIE
Abstract
(EN)
A method of preparing a unique foundry premix composition that has a low bulk density of 30-45 lbs/ft3 and contains fine particles with an average particle size of 85-100 µm is described. The unique foundry premix composition is produced by using specially designed assemblies of mechanical equipment with improved efficiency so that the premix can be prepared at a site closer to a foundry. As a result, increase in premix density caused by handling and shipping across a long distance from a traditional premix manufacturing facility to a foundry can be suppressed; transportation cost can be saved; and safety would be of less concern. The use of the foundry premix composition to prepare a sand molding medium for casting molded articles is also described.
(FR)
L'invention concerne un procédé de préparation d'une composition de prémélange de fonderie unique qui présente une faible masse volumique apparente de 30 à 45 livres/ft3 et qui contient de fines particules dotées d'une taille moyenne de particule de 85 à 100 µm. La composition de prémélange de fonderie unique est produite en utilisant des ensembles spécialement conçus d'équipement mécanique dotés d'une efficacité améliorée, de sorte que le prémélange peut être préparé à un site plus proche d'une fonderie. Par conséquent, l'augmentation de la densité de prémélange provoquée par la manipulation et l'expédition sur une longue distance d'une installation de fabrication de prémélange classique à une fonderie peut être supprimée ; le coût de transport peut être économisé ; et la sécurité est meilleure. L'invention concerne également l'utilisation de la composition de prémélange de fonderie en vue de préparer un milieu de moulage de sable destiné à la coulée d'articles moulés.
