ABSTRACT:
In an automatic foundry plant of the kind in which at an extraction station (41) water is dosed in (at 42) in order to maintain the correct moisture content in the molding sand, which is returned to the molding station (11), and in which new molding sand (at 43), new binder (at 44), and/or new additive (at 45) may be added in a sand treatment station (46), the new feature consists in that the dosing of water and possibly of the other agents mentioned is controlled by means of an automatic control system (51-53) in dependence of information collected upstream of the extraction station regarding the condition of the individual molds arriving at the extraction station, especially with regard to whether metal has been poured in them or not, a very important factor for the moisture content, because this is greatly reduced by the hot metal poured.
