Abstract
A találmány tárgya egy eljárás, amellyel kiváló minőségű, bonyolultalakú öntvényeket lehet előállítani, és amelynél az öntési folyamatvégén az öntőformarészeket veszély nélkül, könnyen el lehet távolítaniaz öntvényből vagy öntvényről. Ennek elérése végett a következőlépéseket hajtják végre: előállítanak egy formázóanyagot úgy, hogyösszekeverik egyrészt a formázó alapanyagot, amely a fémolvadékkalszemben inert és pergő-folyós, továbbá melegedéskor kvarchomoknálkevésbé tágul, másrészt kötőanyagot, amely melegedéskor a formázóalapanyagtól eltérően tágul, előállítanak egy öntőformarészt aformázóanyagból, az öntőformarészt felhasználva összeállítanak egyöntőformát, a fémolvadékot öntvényt formázva az öntőformába öntik, azöntvényt hűtik egy dermedési és hűlési ideig, amely alatt azöntőformarész magától szétesik törmelékdarabokra, az öntőformarésztörmelékdarabjait eltávolítják az öntvényről vagy öntvényből; és aformázóanyag törmelékdarabjait felújítják pergő-folyós formázóalapanyaggá.The subject of the invention is a process by which high-quality, complex-shaped castings can be produced, and in which, at the end of the casting process, the mold parts can be easily removed from the casting or casting without danger. In order to achieve this, the following steps are carried out: a molding material is produced by mixing, on the one hand, the molding material, which is inert to the molten metal and slurry-fluid, and expands less than quartz sand when heated, and, on the other hand, a binder, which expands differently from the molding base material when heated, a mold part is produced from the molding material, the mold part are used to assemble a single casting mold, the molten metal is poured into the mold forming a casting, the casting is cooled for a solidification and cooling time, during which the mold part falls apart by itself into pieces of debris, the debris pieces of the mold part are removed from the casting or from the casting; and scrap pieces of molding material are renovated into snare-fluid molding base material.
