Ke lisebelisoa tsa mofuta ofe tsa sebopi sa induction refractory tse sebelisetsoang aluminium master alloy?

Haufinyane tjena, baetsi ba li-alloys tse kholo tsa induction ba se ba qhibilihisitsoe, ‘me litlhoko tsa lisebelisoa tsa ho rala tsa induction refractory li se li phahame haholo. Litlhoko tsa ho se tsitse, refractoriness, corrosion resistance, joalo-joalo li phahame haholo ho feta litlhoko tse fetileng, hape re tšepa hore litšenyehelo li ka fokotseha. Ho latela tlhoko ea ‘maraka le litlhoko, feme ea thepa ea mocheso o phahameng oa mocheso e fetile tlhahlobo e tsoelang pele le liteko. E atlehile ho nts’etsapele bareki ba bangata ba alloy sebakeng sa lehae, mme e fihletse botumo bo botle mme e hapile thoriso ho tsoa ho bareki. Li-alloys tsa morao-rao ‘marakeng hangata li thehiloe holim’a silicon ea aluminium, koporo ea aluminium, tšepe ea aluminium, boron ea titanium ea aluminium joalo-joalo. Thempereichara ea ho qhibilihisa hangata ha e phahame ho feta ea ho qhibilihisa tšepe, empa e phahame ho feta mocheso o akaretsang oa ho qhibiliha ha aluminium.

Ka lebaka la matla a ho kenella ha aluminium, e ka phunngoa ha u bona seam, ‘me mosebetsi oa aluminium o phahame haholo, o atisang ho fetoha karabelo. Ka hona, lisebelisoa tse ngata tse akaretsang tsa lesela la sebōpi li ke ke tsa hlahisoa ka liboping tse ‘maloa. Ka hona, hona joale ho tloaelehile ho sebelisa li-crucibles tsa graphite tse nang le lisebelisoa tsa ramming tsa sebōpi sa induction refractory. Leha ho le joalo, bofokoli ba lisebelisoa tsa refractory ramming tsa sebōpi se tloaelehileng sa induction ke hore hang ha crucible ea graphite e robehile, lesela la sebōpi le tlameha ho tlosoa, ho seng joalo sebōpi se bonolo ho apara. Lisebelisoa tsa rona tse sa tsoa ntlafatsoa tsa refractory ramming bakeng sa sebōpi sa induction li ke ke tsa sebelisoa li le mong empa hape li ka sebelisoa ka li-crucible tsa graphite. Tabeng ea ho sebelisa hammoho, esita le haeba crucible e robehile ka phoso ha thepa e le tlase ho feta thepa, e ke ke ea ama tšebeliso, e ntse e ka sebelisoa ka linako tsohle, ‘me ha ho hlokahale hore u tšoenyehe ka lesela la sebōpi, se ke keng sa ama mosebetsi o tloaelehileng. Litšenyehelo tse ling ha li phahame. Ho tloha ha e qala, e fumane kapele palo e kholo ea bareki ba master alloy ka thoriso ea sechaba ea bareki.
