Abstract (en)
[origin: WO03024642A1] The invention relates to a method which allows production of high-quality, complex castings and removal of the mold parts from the casting after casting in a simple and reliable manner. The inventive method comprises the following steps: producing a molding material by mixing a flowable base molding material that is inert vis-à-vis the molten bath and that has a lower coefficient of expansion when heated than silica sand, and a binder that has a different expansion behavior when heated than the molding material, producing a mold part from the molding material, assembling a casting mold using the mold parts, pouring the molten bath into the casting mold to give a casting, cooling the casting for a solidification and cooling interval in which the mold part automatically fragments, removing the fragments of the mold part from the casting, and processing the fragments of the molding material to a flowable base molding material.
