Ho lahla litšepe tsa bohlokoa ke bonono ba khale, bo qalileng ka makholo a lilemo. Ho tloha ho etsa mabenyane a rarahaneng ho isa ho liemahale tse majabajaba, mokhoa oa ho etsa litšoantšo o lumella litsebi tsa mesebetsi ea matsoho hore li fetole thepa e tala hore e be mesebetsi e tsotehang ea bonono. Tataisong ena, re tla batlisisa ka har'a mechini le mekhoa e sebelisoang ho etsa litšepe tsa bohlokoa, ho fana ka kakaretso e felletseng ea mosebetsi ona o khahlang.

Ithute ka mokhoa oa ho etsa litšepe tsa bohlokoa
Pele re hlahloba mechine e khethehileng e sebelisetsoang ho lahla litšepe tsa bohlokoa, ho bohlokoa ho utloisisa ts'ebetso eohle. Ho lahla ho akarelletsa ho qhibiliha tšepe, ho e tšela ka har'a hlobo, ebe e lumella hore e pholile le ho tiea. Ts'ebetso ena e ka etsa libopeho tse rarahaneng le meralo eo ho ka bang thata kapa ho ke keng ha khoneha ho e fihlela ka mekhoa e meng.

Mechini ea ho akhela litšepe tsa bohlokoa
1. Sebōpi sa Crucible
E 'ngoe ea mechini ea bohlokoa e sebelisetsoang ho akhela litšepe tsa bohlokoa ke sebōpi sa crucible. Sebōpi sa mofuta ona se etselitsoe ho finyella mocheso o phahameng ho qhibilihisa litšepe tse kang khauta, silevera le platinum bakeng sa ho akhela. Libōpi tsa crucible li tla ka boholo bo fapaneng, ho tloha ho mehlala e menyenyane ea litafole tse sebelisetsoang ho roala mabenyane ho ea ho lihlopha tse kholo tsa indasteri tse sebelisetsoang tlhahiso ea bongata.

2. Mochine oa ho lahla oa Centrifugal
Mechini ea ho lahla ea Centrifugalhangata li sebelisoa ho lahlela lisebelisoa tse nyane, tse rarahaneng joalo ka likarolo tsa mabenyane. Mochini oa mofuta ona o sebelisa matla a centrifugal ho aba tšepe e qhibilihisitsoeng ka ho lekana ka har'a hlobo, ho hlahisa li-castings tsa boleng bo holimo tse nang le porosity e nyane. Mechini ea ho lahla ea Centrifugal e fumaneha ka mefuta ea matsoho le ea othomathiki, e fana ka maemo a bonolo ho litsebi tsa mesebetsi ea matsoho le bahlahisi.

3. Mochine oa ho bopa ente ea vacuum
Mechini ea Vacuum casting e bohlokoa bakeng sa ho fumana lisebelisoa tsa boleng bo holimo, tse se nang letho. Mechini ena e sebetsa ka ho etsa tikoloho ea vacuum e tlosang moea le likhase mokoting oa hlobo pele e tšela tšepe e qhibilihisitsoeng. Ts'ebetso ena e thusa ho felisa lipokotho tsa moea le ho netefatsa hore tšepe e tlatsa hlobo ka ho feletseng, e leng se etsang hore ho be le ho lahla ho nepahetseng le ho phethahetseng.

4. Sebōpi se qhibilihang sa induction
Bakeng sa ts'ebetso e kholo ea tlhahiso le ea indasteri,libopi tse qhibilihang ka inductionli sebelisoa hangata. Lisebelisuoa tsena li sebelisa motlakase oa motlakase ho futhumatsa le ho qhibilihisa tšepe, ho fana ka taolo e nepahetseng ea mocheso le matla a matla. Lisebelisuoa tsa ho qhibiliha tsa induction li khona ho qhibilihisa mefuta e fapaneng ea litšepe, e leng se etsang hore e be sesebelisoa se feto-fetohang bakeng sa ho lahlela litšepe tsa bohlokoa ka tekanyo e kholo.

Theknoloji ea ho lahla tšepe ea bohlokoa
Ntle le mechini e sebelisoang ho akhela litšepe tsa bohlokoa, litsebi tsa mesebetsi ea matsoho le bahlahisi ba sebelisa mekhoa e fapaneng ho fihlela phello e lakatsehang. Tse ling tsa mekhoa e tsebahalang haholo li kenyelletsa:

- Lost Wax Casting: Mokhoa ona oa khale o kenyelletsa ho theha mohlala oa boka ba ntho e lakatsehang ebe o o kenya ka har'a hlobo. Boka bo a qhibiliha ebe bo tsoa metsi, bo siea sekoti se tletseng tšepe e qhibilihisitsoeng ho etsa mokhabiso oa ho qetela.

- Ho Lahlela Lehlabathe: Ho lahla lehlabathe ke mokhoa o feto-fetohang le o theko e boima oa ho akhela tšepe. E akarelletsa ho etsa hlobo ka ho kopanya lehlabathe ho pota-pota mohlala, ebe o tlosoa ho siea lesoba leo tšepe e tšeloang ho lona.

- Investment Casting: E ​​boetse e tsejoa e le "lahleha ea boka ba linotsi," ho etsa matsete ho kenyelletsa ho etsa mohlala oa boka o koahetsoeng ka khetla ea ceramic. Boka bo a qhibiliha 'me khetla ea ceramic e tlatsitsoe ka tšepe e qhibilihisitsoeng ho etsa ho lahla.

- Die Casting: Die casting ke mokhoa o sebetsang hantle haholo oa ho hlahisa likarolo tse ngata tsa tšepe tse nepahetseng haholo. E kenyelletsa ho qobella tšepe e qhibilihisitsoeng ka mokoting oa hlobo tlas'a khatello e phahameng, e hlahisang libopeho tse rarahaneng le mamello e thata.

ha re phethela
Ho lahla litšepe tsa bohlokoa ke mosebetsi o hlomphuoang ka nako e telele o ntseng o atleha le mehleng ea kajeno. Ka ho utloisisa mechine le mekhoa e sebelisoang ho etsa litšepe tsa bohlokoa, litsebi tsa mesebetsi ea matsoho le baetsi ba tsona ba ka etsa likotoana tse ntle tse bontšang botle le ho feto-fetoha ha thepa ena ea bohlokoa. Hore na ke ho etsa mabenyane a rarahaneng kapa ho hlahisa likarolo tsa indasteri, bonono ba ho etsa litšepe tsa bohlokoa e lula e le karolo ea bohlokoa lefats'eng la tlhahiso le bonono.
