Abstract
Eljárás magnéziumtartalmú darabos hulladékok feldolgozására,elsősorban kistömegű, nagyfelületű, gyúlékony apróhulladékok, továbbáforgácsok öntészeti minőségű másodlagos alapanyaggá valófeldolgozására olvasztás útján, amely eljárást légmentesen záró,alacsonyértékű túlnyomásra, illetve vákuumra méretezett, kettősfalúolvasztótérben, vákuumkemencében, ciklikusan hajtják végre. Avákuumkemence fűtését bármely ismert hőközlési elven megvalósíthatják.A felfűtés kezdetétől az olvasztótérben vákuumot hoznak létre és aztaz olvasztási ciklus alatt folyamatosan fenntartják, majd azolvasztási ciklus befejezésekor az olvadék feletti teret semlegesvédőgázzal azonnal feltöltik, az olvadék feletti védőgázzal feltöltöttteret folyamatosan a légköri nyomás felett tartva felnyitják atégelyt, és az ily módon a fémfürdő felületére juttatott takaró- éstisztítósókkal együtt a fémfürdőt folyamatos keveréssel átkeverik éseközben előnyösen folyamatosan semleges védőgázt juttatnak a fémfürdőbelsejébe, majd a képződött salakot eltávolítják a fémfürdőfelszínéről. A keverést addig folytatják, amíg a salakképződésfennáll, ezután újabb magnéziumtartalmú fémbetétet helyeznek atégelybe, a fémbetét behelyezése alatt és a tégely ezt követő azonnalilezárásáig mindvégig fenntartják a védőgáz betöltését, majd a tégelyzárásának befejezésével egyidejűleg a vákumrendszert a fémbetétfeletti térre nyitják, és a védőgáz betöltését egyidejűlegmegszüntetik. A második és további olvasztási és tisztítási ciklusoksorán ugyanezt a folyamatot ismételve folytatják a kivánt olvadéktömegeléréséig, ennek elérésekor a megolvadt fémet pihentetik, majd atégelyből bármely ismert módon kiöntik ÓProcess for the processing of magnesium-containing piece waste, primarily small-weight, large-surface, inflammable small waste, and also for the processing of shavings into foundry-quality secondary raw materials by means of melting, which is carried out cyclically in an airtight, low-value overpressure or vacuum, double-walled melting chamber, in a vacuum furnace. A vacuum furnace can be heated using any known heat transfer principle. From the beginning of the heating, a vacuum is created in the melting chamber and it is continuously maintained during the melting cycle, then at the end of the melting cycle, the space above the melt is immediately filled with neutral shielding gas, the space above the melt filled with shielding gas is continuously kept above atmospheric pressure, and the furnace is opened, and together with the covering and cleaning salts applied to the surface of the metal bath in this way, the metal bath is mixed by continuous stirring, and in the meantime a neutral shielding gas is preferably continuously supplied to the inside of the metal bath, and then the formed slag is removed from the surface of the metal bath. The mixing is continued until slag formation occurs, then another magnesium-containing metal insert is placed in the crucible, during the insertion of the metal insert and until the immediate closing of the crucible, the filling of the shielding gas is maintained throughout, and then, at the end of the crucible closure, the vacuum system is opened to the space above the metal insert, and the filling of the shielding gas is stopped at the same time. During the second and subsequent melting and cleaning cycles, the same process is repeated until the desired melt mass is reached. When this is reached, the molten metal is left to rest and then poured out of the crucible in any known way.
