| 摘要 | A method for producing iron metal castings, wherein an expendable mold having a cavity for holding casting material is inserted into an opened multi-part permanent mold, the permanent mold is closed, the cavity is filled with casting material, wherein a supporting device partially protruding into the cavity is partially overcast, the expendable mold is cooled in the permanent mold after the filling, the permanent mold is opened during the cooling, after the liquidus temperature has been fallen below at the earliest, and the expendable mold is nondestructively removed from the permanent mold together with the casting, the expendable mold is further cooled together with the solidified casting while hanging on the supporting device, at least until the microstructure formation of the casting is concluded, the casting is demolded by removing the expendable mold. | ||||||
