Ho na le mefuta e mengata ea ho lahla, eo ka tloaelo e arotsoeng ka:
① Ho lahla lehlabathe ho tloaelehileng, ho kenyeletsoa lehlabathe le metsi, lehlabathe le omeletseng le lehlabathe le thatafalitsoeng ke lik'hemik'hale.
② Ho lahla ho khethehileng, ho ea ka thepa ea mohlala, e ka aroloa ka ho lahla ho khethehileng ka lehlabathe la tlhaho la liminerale e le thepa e ka sehloohong ea mohlala (e kang ho lahla matsete, ho lahla seretse, ho lahla likhetla tsa workshop, ho lahla khatello e mpe, ho lahla ka thata, ho lahla ceramic joalo-joalo. .) le li-castings tse khethehileng tse nang le tšepe e le lisebelisoa tse ka sehloohong tsa ho lahla (tse kang ho lahla hlobo ea tšepe, ho lahla khatello, ho tsoela pele, ho fokotsa khatello e tlaase, ho lahla centrifugal, joalo-joalo).
Hangata mokhoa oa ho lahla o kenyelletsa:
① Tokisetso ea liforomo (lits'oants'o tse etsang tšepe ea metsi hore e be li-castings tse tiileng).Ho ea ka lisebelisoa tse sebelisoang, ho lahla liforomo ho ka aroloa ka liforomo tsa lehlabathe, lihlahisoa tsa tšepe, li-mold tsa ceramic, li-mold tsa letsopa, li-graphite, joalo-joalo.
② Ho qhibiliha le ho tšolloa ha litšepe tse entsoeng, litšepe tse entsoeng ka tšepe (li-alloys) haholo-holo li kenyelletsa tšepe e entsoeng ka tšepe, tšepe e entsoeng ka tšepe le li-alloys tse se nang ferrous;
③ Kalafo ea ho lahla le ho hlahloba, phekolo ea ho lahla e kenyelletsa ho tlosoa ha lintho tse tsoang linaheng tse ling mokokotlong le holim'a metsi, ho tlosoa ha li-rosers tse tšollang, ho sila li-burrs le seams le li-protrusions tse ling, hammoho le phekolo ea mocheso, sebōpeho, phekolo e khahlanong le mafome le machining. .
Melemo
(1) E ka etsa mefuta e fapaneng ea libopeho tse rarahaneng, joalo ka lebokose, foreimi, bethe, cylinder block, joalo-joalo.
(2) Boholo le boleng ba li-castings li batla li sa thibeloe, tse nyenyane joaloka limilimithara tse seng kae, ligrama tse seng kae, tse boholo ba limithara tse leshome, lithane tse makholo tsa li-castings li ka lahleloa.
(3) E ka lahlela lisebelisoa life kapa life tsa tšepe le alloy.
(4) Thepa ea tlhahiso ea ho lahla e bonolo, ho tsetela ho fokolang, ho lahlela ka mefuta e mengata ea lihlahisoa tse tala, kahoo litšenyehelo tsa ho lahla li tlaase.
(5) Sebopeho le boholo ba ho lahla li haufi le likarolo, kahoo mosebetsi oa ho itšeha o fokotsehile 'me lisebelisoa tse ngata tsa tšepe li ka bolokeha.
Hobane casting e na le melemo e kaholimo, e sebelisoa haholo ha ho etsoa likarolo tsa mochini.
Ts'ebetso ea ho lahla e ka aroloa likarolo tse tharo tsa motheo, e leng ho lahla tšepe ho lokisa, ho lokisetsa hlobo ea ho lahla le ho sebetsa ka ho lahla.Cast metal e bolela thepa ea tšepe e sebelisetsoang ho etsa castings tlhahiso ea ho lahla.Ke motsoako o entsoeng ka karolo ea tšepe kaha karolo e ka sehloohong le lisebelisoa tse ling kapa likarolo tse seng tsa tšepe li kenngoa.Ka tloaelo e bitsoa alloy casting, haholo-holo e kenyelletsang tšepe e entsoeng ka tšepe, tšepe ea Cast le li-alloys tse sa sebeliseng ferrous.
