Abstract (en)

An installation for the coating of foundry cores by soaking in a bath (2) of an aqueous coating contained in a tank (3). A rheometer (13) measures the viscosity of the bath (2) and a level sensor (14) measures the level of the bath (2). A computer (17 allows the regulation of the rheological properties of the bath (2) by supplying water and/or the coating paste. A static mixer connected to a reservoir (30) of primary coating and to a source of water delivering the supply of water and/or coating paste in the tank (3). The tank (3) is also equipped with a circuit for regulating the temperature of the bath (2).

Abstract (fr)

L'invention concerne une installation d'enduisage de noyaux de fonderie par trempage dans un bain (2) d'un enduit aqueux contenu dans une cuve (3). Un rhéomètre (13) mesure la viscosité du bain (2), et un capteur de niveau (14) mesure le niveau du bain (2). Un organe de calcul (17) permet de réguler par apport d'eau et/ou d'enduit pâteux les propriétés rhéologiques du bain. Un mélangeur statique relié à une réserve (30) d'enduit primaire et à une source d'eau délivre l'apport d'eau et/ou d'enduit pâteux dans la cuve (3). La cuve (3) est en outre équipée d'un circuit de régulation de la température du bain (2). <IMAGE>
