Ingano yo gukwirakwiza ibice byumucanga mbisi bigira ingaruka cyane kumiterere ya casting. Iyo ukoresheje coarser grit, icyuma gishongeshejwe gikunda gucengera muri grit ya grit, bikavamo ubuso bubi. Gukoresha umucanga mwiza birashobora gutanga umusaruro mwiza kandi woroshye wo guteramo, ariko bisaba urugero rwinshi rwa binder, kandi mugihe kimwe bigabanya umwuka wimyuka wibanze, bishobora gutera inenge. Muri rusange gahunda yo guta umucanga, cyane cyane iyo umucanga wa silika ukoreshejwe, umucanga mbisi muri rusange uri mubunini bukurikira:
Impuzandengo nziza ya 50-60 AFS (impuzandengo yubunini bwa 220-250 mm): ubuziranenge bwubuso bwiza no gukoresha binder yo hasi
Ifu nziza (munsi ya 200 mesh) ibirimo ≤2%: irashobora kugabanya ingano ya binder
Ibirimo ibyondo (ibice bitarenze 0.02mm) ≤0.5%: birashobora kugabanya ingano ya binder
Ingano yubunini bwagabanijwe: 95% byumucanga byibanze kumashanyarazi ya 4 cyangwa 5: byoroshye guhuza no kugabanya inenge zo kubyimba
Umwuka wumuyaga wumucanga wumye: 100-150: gabanya inenge
Umucanga wa Ceramic, bitewe nuburinganire bwawo hafi yizengurutse, amazi meza cyane, ubwinshi bwumuyaga mwinshi, hamwe nibiranga ubunini bwagutse bwagabanijwe hamwe no guhuza inshundura imwe ivanze mubikorwa, mubikorwa byo gutara, usibye gukurikiza ibintu bisanzwe byavuzwe haruguru, hari Ibiranga byihariye byihariye biranga itandukanyirizo no gutandukana mugihe cyo gutwara no gutwara; ifite imbaraga zitose mugukoresha umucanga wicyatsi kibisi kandi nta-guteka umucanga. Kubikorwa byo guta umucanga ukoresheje binders, gukoresha gukwirakwiza amashanyarazi menshi bituma uduce duto twuzuza icyuho kiri hagati yinini nini kandi tugashyira hamwe, byongera "ikiraro gihuza" cya binder, bityo bikazamura imbaraga zubusabane bwibanze, nibindi Ni inzira nziza.
Mu ncamake ikoreshwa ryumucanga wumubumbyi mumyaka irenga 20, ingano yubunini busabwa no gukwirakwiza umucanga wa ceramique ukoreshwa muburyo butandukanye bwo gutondeka urutonde rukurikira:
● RCS (Resin Coated Ceramic Sand)
AFS indangagaciro za 50-70, 70-90, na 90-110 zose zirakoreshwa, zigabanywa mumashanyarazi 4 cyangwa 5, kandi kwibanda hejuru ya 85%;
● Oya-guteka umucanga
(Harimo furan, alkali fenolike, PEP, Bonnie, nibindi): AFS 30-65 irakoreshwa, gukwirakwiza 4 cyangwa gukwirakwiza amashanyarazi 5, kwibanda hejuru ya 80%;
Inzira Yatakaye Ifuro / Gutakaza Ibiro Byashizweho
10/20 mesh na 20/30 mesh zikoreshwa cyane, zishobora guteza imbere ikirere, kwemeza igipimo cyongera gutunganya umucanga ceramique nyuma yo gusuka, no kugabanya ibyo ukoresha;
Box Agasanduku gakonje k'umusenyi
AFS 40-60 ikoreshwa cyane, ikwirakwizwa hamwe na 4 cyangwa 5, kandi kwibanda hejuru ya 85%;
Icapa rya 3D
Amashanyarazi 2 aratangwa, kugeza kumashanyarazi agera kuri 3, hamwe nibice birenga 90%, byemeza umubyimba umwe wumucanga. Impuzandengo nziza ikwirakwizwa cyane ukurikije imikoreshereze itandukanye
