Title (EN) SAND TESTING METHOD AND APPARATUS
(FR) DISPOSITIF DE VERIFICATION DU SABLE DE FONDERIE ET PROCEDE ASSOCIE
Abstract:
(EN) An apparatus (10) and method for testing the quality of foundry green sand. The apparatus includes three testing stations where filling (60), compaction (80), weighing (94), gas permeability testing (120), moisture testing (40), fracture testing (160), and shear testing (180) occur. Each station is automated and controlled by a computer programmed control system or controller (200). Known foundry sand testing formulas are entered into the system or controller which in turn receives input from each of the testing stations. The condition and quality of the foundry sand is output. A method for testing is also disclosed.
(FR) L'invention porte sur un dispositif (10) et un procédé de vérification de la qualité de sables verts de fonderie comportant trois stations d'essai évaluant le remplissage (60), le compactage (80), le poids (94), la perméabilité aux gaz (120), l'humidité (40), la résistance à la rupture (160), et la résistance au cisaillement (180). Chacune des stations est automatique et gérée par un système de commande par ordinateur ou par un contrôleur (200). Les formules de vérification connues applicables au sable de fonderie sont introduites dans le système ou dans le contrôleur qui reçoivent ensuite des données entrées de chacune des stations de vérification. Les résultats portent sur l'état et la qualité du sable de fonderie. L'invention porte également sur un procédé d'essai associé.
