A: Khatello ea khatello ke mokhoa oa ho lahla moo mokelikeli o qhibilihisitsoeng oa alloy o tšeloang ka kamoreng ea khatello, sekoti sa hlobo ea tšepe se tlatsoa ka lebelo le phahameng, 'me mokelikeli oa alloy o tiisoa tlas'a khatello ea ho etsa casting.Likarolo tse ka sehloohong tsa ho lahlela lefu tse e khethollang ho mekhoa e meng ea ho lahla ke khatello e phahameng le lebelo le phahameng.

Mechini e bolaeang, li-alloys tse etsang die-casting le hlobo ea die-casting ke lintlha tse tharo tse kholo tsa tlhahiso ea li-die-casting 'me li bohlokoa haholo.Ntho e bitsoang "die-casting process" ke motsoako oa lintho tse tharo tsa likarolo tsena tse tharo, tse nolofalletsang tlhahiso e tsitsitseng, e nang le morethetho le e sebetsang hantle ea li-castings ka ponahalo, boleng bo botle ba ka hare, le boholo ba litšoantšo kapa litlhoko tsa tumellano.

A:

(1) E ka fihlela litlhoko tsa ts'ebetso ea li-castcasts.

(2) Sebaka sa ho qhibiliha se tlaase, mocheso oa mocheso oa crystallization o monyenyane, metsi a mocheso ka holim'a ntlha ea ho qhibiliha a ntle, 'me palo ea ho fokotseha ka mor'a ho tiisa e nyenyane.

(3) E na le matla a lekaneng le polasetiki ka mocheso o phahameng, 'me e na le brittleness e tlaase e chesang.

(4) Lintho tse ntle tsa 'mele le tsa lik'hemik'hale tse kang ho hanyetsa, motlakase, conductivity ea mocheso, le ho hanyetsa kutu.

A: Ka kakaretso, ts'ebeliso ea 'nete indastering ea li-die-casting ha se 100% aluminium e hloekileng, empa e na le dikahare tsa aluminium tse tlohang ho 95% ho isa ho 98.5% (alloy ea die-cast aluminium e nang le ts'ebetso e ntle ea anodizing), mme aluminium e hloekileng e hloka ho ba le ho feta 99.5% aluminium (E kang aluminium e hloekileng ea rotor die casting).Ka lebaka la ts'ebetso ea eona e ntle ea mocheso le lisebelisoa tsa anodizing, alumina e atisa ho sebelisoa litšeng tsa mocheso le phekolo ea holim'a metsi moo litlhoko tsa mebala li leng holimo.

Ha ho bapisoa le aluminium e tloaelehileng ea alloy die-casting (e kang ADC12), ka lebaka la litaba tse phahameng tsa silicon, tekanyo ea ho fokotseha e batla e le nyenyane 4-5%;empa alumina ha e le hantle ha e na silicon, sekhahla sa shrinkage ke 5-6%, kahoo motsoako o tloaelehileng oa aluminium alloy die-casting ha o na phello ea anodizing.

A: Mechini ea li-die-casting e ka aroloa ka mefuta e 'meli, mochini o chesang oa kamore e chesang le mochini o batang oa ho lahla.Phapang ke hore na li ka mamella matla a makae.Khatello e tloaelehileng e tloha ho lithane tse 400 ho isa ho tse 4,000.Hot chamber die casting ke tšepe e qhibilihantsoeng, e metsi, e nang le halofo ea metsi ka letamong la tšepe le tlatsang hlobo tlas'a khatello.Cold die casting e ka sebelisoa bakeng sa litšepe tsa die casting tse ke keng tsa sebelisoa lits'ebetsong tse chesang tsa kamore e chesang, ho kenyeletsoa aluminium, magnesium, koporo le lialloys tsa zinki tse nang le aluminium e phahameng.Ts'ebetsong ena, tšepe e hloka ho qhibiliha pele ka crucible e arohaneng.Tekanyo e itseng ea tšepe e qhibilihisitsoeng ebe e fetisetsoa phaposing ea ente e sa chesoang kapa molomong oa molomo;phapang pakeng tsa kamore e chesang le kamore e batang ke hore na tsamaiso ea ente ea mochine oa ho lahla o qoelisoa ka tharollo ea tšepe.

A: Mochini oa ho lahla oa kamore e chesang: motsoako oa zinki, motsoako oa magnesium, joalo-joalo.

Cold chamber die casting machine: zinki alloy, magnesium alloy, aluminium alloy, koporo alloy, joalo-joalo.

Mochini o otlolohileng oa ho lahla: zinki, aluminium, koporo, lead, tin;

A:

1. Ts'ebetso e ntle ea ho lahla

2. Boima bo tlaase (2.5 ~ 2.9 g / cm 3), matla a phahameng.

3. Mokelikeli oa tšepe o nang le khatello e phahameng le lebelo la ho phalla ka potlako nakong ea ho lahla lefu

4, boleng ba sehlahisoa bo botle, boholo bo tsitsitse, 'me phapanyetsano e ntle;

5, ts'ebetso e phahameng ea tlhahiso, palo ea makhetlo a sebelisoang ke hlobo ea die-casting;

6, e loketseng palo e kholo ea tlhahiso e kholo, phaello e ntle ea moruo.

A: Hangata e sebelisoa ha ho phekoloa likarolo tsa aluminium alloy die-casting ke: pente ea electrophoretic, electroplating, ente ea peterole, ho phatloha ha lehlabathe, ho phatloha ho thunngoa, anodizing, varnish ea ho baka, mocheso o phahameng oa ho baka varnish, anti-rust passivation joalo-joalo.
