Abstract

A találmány öntészeti mag-időmdarabők gyártási eljárására vőnatkőzik,melynek sőrán a) szervetlen tűzálló főrmázóhőmők és vízüveg alapúszervetlen kötőanyag keveréket állítanak elő, b) a keveréket temperáltmagszekrénybe öntik, c) a keverékben levő vizet fizikaieljárással kivőnják, d) a mag elő-időmdarabőt kiemelik amagszekrényből. Az eljárást az jellemzi, hőgy e) a temperáltmagszekrényt a töltés alatt depressziónak vetik alá, f) ahőmérsékletet és tartózkődási időt úgy szabályőzzák be a magszekrényzárása űtán, hőgy az időmdarab szélén mérettartó és jó hőrdképességűhéj alakűljőn ki, g) a magszekrény nyitása űtán rögtön eltávőlítják azidőmdarabőt és mikrőhűllámők hatására teljes szárításnak vetik alá. Atalálmány tárgya tővábbá őlyan, körfőrgásban tartőtt maghőmőkelőállítása, mely régi magők maradékanyagaiból áll. ŕThe invention is based on the production process of casting core-temporary pieces, in which a) a mixture of inorganic refractory main heat and water glass-based inorganic binder is produced, b) the mixture is poured into a tempered core cabinet, c) the water in the mixture is extracted by a physical process, d) the core pre-timber is removed from the core cabinet . The procedure is characterized by: e) the tempered core cabinet is subjected to depression during filling, f) the temperature and holding time are regulated when the core cabinet is closed, so that a dimensionally stable and good heat capacity shell forms on the edge of the time piece, g) the time piece is removed immediately after the core cabinet is opened and subjected to complete drying under the influence of microwave ovens. The subject of the invention is the production of nuclear thermal energy, which is kept in a circle for a long time, which consists of the remaining materials of old cores. ŕ
