Ke lisebelisoa life tse sebelisetsoang ho qhekella?

Lisebelisoa tsa ho qhekella haholo-holo li na le tšepe ea carbon le alloy e nang le mefuta e sa tšoaneng, e lateloa ke aluminium, magnesium, koporo, titanium le li-alloys tsa tsona. Maemo a mantlha a lisebelisoa a kenyelletsa bar, ingot, phofo ea tšepe le tšepe ea metsi. Karo-karolelano ea sebaka sa tšepe ea tšepe pele ho ho kheloha ho ea sebakeng se ka morao ka mor'a ho senyeha ho bitsoa karo-karolelano ea forging. Khetho e nepahetseng ea karo-karolelano ea ho forging, mocheso o loketseng oa ho futhumatsa le nako ea ho ts'oara, mocheso o loketseng oa pele le oa ho qetela oa ho qhekella, tekanyo e lekaneng ea deformation le lebelo la deformation li amana haufi-ufi le ho ntlafatsa boleng ba sehlahisoa le ho fokotsa litšenyehelo.

Ka kakaretso, lisebelisoa tse chitja kapa tsa lisekoere li sebelisoa e le likheo tsa ho forging tse nyane le tse mahareng. Sebopeho sa lijo-thollo le thepa ea mechine ea thepa ea bar e tšoana hantle ebile e ntle, e na le sebōpeho se nepahetseng le boholo, boleng bo botle ba holim'a metsi, 'me ho bonolo ho e hlophisa bakeng sa tlhahiso ea bongata. Ha feela mocheso o futhumatsang le maemo a deformation a laoloa ka mokhoa o utloahalang, li-forging tsa boleng bo phahameng li ka etsoa ntle le ho senyeha ha bohlokoa. Li-ingots li sebelisoa feela bakeng sa ho forging tse kholo. Ingot ke mohaho o entsoeng ka tšepe o nang le likristale tse kholo tsa columnar le litsi tse hlephileng. Ka hona, hoa hlokahala ho pshatla likristale tsa columnar hore e be lijo-thollo tse ntle ka ho senyeha ho hoholo ha polasetiki, le ho li kopanya ka mokhoa o hlephileng e le ho fumana sebopeho se setle sa tšepe le thepa ea mochine.

Li-preforms tsa metallurgy tse entsoeng ka ho tobetsa le ho thunngoa li ka etsoa li-forgings tsa phofo ka ho se be le flash sebakeng se chesang. Boima ba phofo ea forging bo haufi le ba lifereko tse akaretsang, tse nang le thepa e ntle ea mochini le ho nepahala ho phahameng, tse ka fokotsang ts'ebetso e latelang ea ho itšeha. Sebopeho sa ka hare sa li-forgings tsa phofo ke junifomo ntle le khethollo, 'me e ka sebelisoa ho etsa lisebelisoa tse nyenyane le lisebelisoa tse ling tsa mosebetsi. Leha ho le joalo, theko ea phofo e phahame haholo ho feta ea lisebelisoa tse tloaelehileng tsa bar, e fokotsang tšebeliso ea eona tlhahiso. Ka ho sebelisa khatello e tsitsitseng ho tšepe ea metsi e tšeloang ka har'a hlobo ea hlobo, e ka tiisa, ea crystallize, ea phalla, ea kena ka tlas'a khatello ea ho fumana sebopeho le thepa ea forging. Mokelikeli tšepe forging ke mokhoa oa ho theha pakeng tsa die casting le die forging, haholo-holo e loketseng bakeng sa likarolo tse rarahaneng tse tšesaane tse nang le marako ao ho leng thata ho a theha ka kakaretso ea die.

Ntle le lisebelisoa tse tloaelehileng tse kang tšepe ea carbon le tšepe ea alloy e nang le lihlopha tse sa tšoaneng, lisebelisoa tsa ho haha ​​li boetse li kenyelletsa aluminium, magnesium, koporo, titanium le li-alloys tsa tsona. Li-alloys tsa tšepe tse nang le mocheso o phahameng oa tšepe, li-alloys tsa mocheso o phahameng oa nickel, le li-alloys tsa mocheso o phahameng oa cobalt le tsona li entsoe kapa li phuthoa joalo ka li-alloys tsa deformation. Leha ho le joalo, li-alloys tsena li na le libaka tse nyenyane tsa polasetiki, tse etsang hore ho be thata ho theha. Lisebelisoa tse fapaneng li na le litlhoko tse tiileng tsa mocheso oa ho futhumatsa, mocheso oa forging, le mocheso oa ho qetela oa forging.
