Installation of the coating of foundry mold cores with an aqueous coating

摘要

The invention relates to an installation for coating of foundry mold cores by dipping in a bath (2) of an aqueous compound contained in a vat (3). A rheometer (13) measuring the viscosity of the bath (2), and a level sensor (14) measures the level of the bath (2). A computation device (17), makes it possible to control by the addition of water and / or pasty coated the rheological properties of the bath. A static mixer connected to a reserve (30) of the primary coating and to a water source delivers the addition of water and / or pasty coated in the tank (3). The tank (3) is also equipped with a circuit for regulating the temperature of the bath (2).
