Abstract (en)
[origin: WO2015036184A1] The present invention relates to a device for hardening foundry cores of a moulding material containing sand, in which, for being hardened, the core is exposed in a core forming tool to a catalyst-vapour/carrier-gas mixture and subsequently to a stream of compressed air, each at a prescribed pressure and a prescribed temperature, wherein a heating and mixing stage that can be arranged upstream of the core forming tool is connected to a tank containing an organic catalyst in liquid form and to a compressed air source, wherein the device does not have a preheater, and so the liquid organic catalyst and the compressed air are heated together in the heating and mixing stage, and the device has a separate flushing line, wherein a first shut-off valve is arranged in the line to the heating and mixing stage and is closed at the beginning of the flushing, and a second shut-off valve is arranged in the flushing line and is open at the beginning of the flushing.
