Ngaphansi kwezimo ezijwayelekile, ukunemba kohlangothi kokunemba kokulingisa kuthintwa izici eziningi ezifana nesakhiwo sobungcweti, izinto ezibukwayo, ukwakheka kwesikhunta, ukwenziwa kwamagobolondo, ukubhaka, ukuthelwa, njll. Noma isiphi isilungiselelo noma ukusebenza okungenangqondo kwanoma isiphi isixhumanisi kuzoshintsha izinga lokuncipha ukuphonsa.Lokhu kuholela ekuphambukeni ekunembeni kwe-dimensional kokulingisa kusukela kuzimfuneko.Okulandelayo yizici ezingabangela ukukhubazeka ekunembeni kobukhulu bokunemba kokulingisa:
(1) Umthelela wesakhiwo sokulingisa: a.Ukujiya kodonga, izinga lokushwabana elikhulu, udonga olucijile oluncanyana, izinga lokushwabana elincane.b.Izinga lokushwabana kwamahhala likhulu, futhi izinga lokushwabana elivinjiwe lincane.
(2) Umthelela wezinto ezibunjiweyo: a.Uma kuphezulu okuqukethwe kwekhabhoni endabeni, kuba kuncane izinga lokuncipha komugqa, kanye nenani eliphansi lekhabhoni, likhulu izinga lokuncipha ngomugqa.b.Izinga lokuncipha lokuphonsa lezinto ezijwayelekile limi kanje: izinga lokuncipha lokuphonsa K=(LM-LJ)/LJ×100%, i-LM ingusayizi wesikhala, futhi i-LJ ingusayizi wokulingisa.I-K ithintwa yizici ezilandelayo: isikhunta se-wax i-K1, isakhiwo sokuphonsa i-K2, uhlobo lwe-alloy K3, ukushisa okuthululwayo K4.
(3) Umthelela wokwenziwa kwesikhunta esilinganisweni sokushwabana somugqa wokubunjwa: a.Umthelela wezinga lokushisa lomjovo we-wax, ingcindezi yomjovo we-wax, kanye nesikhathi sokubamba ingcindezi kusayizi wokutshala imali kusobala kakhulu ekushiseni komjovo we-wax, kulandelwa ingcindezi yomjovo we-wax, futhi isikhathi sokubamba ingcindezi siqinisekisiwe Ngemuva kokuthi ukutshalwa kwezimali kusungulwe. kunomthelela omncane kusayizi wokugcina we-investimenti.b.Izinga lokushwabana kwe-wax (isikhunta) lilingana no-0.9-1.1%.c.Lapho isikhunta sokutshala izimali sigcinwa, kuzoba nokuncipha okuqhubekayo, futhi inani layo lokunciphisa lingaba ngu-10% wesamba sokuncipha, kodwa lapho kugcinwa amahora angu-12, usayizi wesikhunta sokutshala izimali uzinzile ngokuyisisekelo.d.Izinga lokuncipha kwe-radial lesikhunta se-wax singama-30-40% kuphela wezinga lokushwabana ngobude.Izinga lokushisa lomjovo we-wax linomthelela omkhulu kakhulu ekuncipheni kwamahhala kunezinga lokushwabana elivinjiwe (izinga lokushisa elingcono kakhulu lomjovo we-wax ngu-57-59℃, Uma izinga lokushisa liphezulu, kulapho kuncipha khona).
(4) Ithonya lezinto zokwenza igobolondo: isihlabathi se-zircon, i-zircon powder, isihlabathi se-Shangdian kanye ne-Shangdian powder kusetshenziswa.Ngenxa ye-coefficient yabo encane yokunweba, i-4.6×10-6/℃ kuphela, inganakwa.
(5) Umthelela wokubhaka kwegobolondo: Ngenxa yokuthi i-coefficient yokwandisa igobolondo incane, lapho izinga lokushisa legobolondo lingu-1150 ℃, liyi-0.053% kuphela, ngakho-ke lingashaywa indiva.
(6) Umthelela wokushisa okuphonswayo: ukuphakama kwezinga lokushisa lokusakaza, izinga lokuncipha libe likhulu, kanye nezinga lokushisa eliphansi le-casting, izinga lokushwabana liba lincane, ngakho izinga lokushisa lokusakaza kufanele lifaneleke.
