Shijiazhuang Donghuan malleable Iron casting coated sand casting process

Uyu munsi, nzakujyana muri Donghuan Malleable Iron Casting Co., Ltd. Reka twige ibijyanye no guta umucanga usize.

I.Kumenya no gusobanukirwa umucanga utwikiriwe

1. Ibiranga umucanga usize

Ifite imbaraga zikwiye;amazi meza, ibishushanyo byumucanga byateguwe hamwe numusenyi wumusenyi bifite imiterere isobanutse nuburyo bwuzuye, bushobora kubyara umusenyi utoroshye;ibishushanyo byumucanga (cores) bifite ubuziranenge bwubuso, kandi uburinganire bwubuso bushobora kugera kuri Ra = 6.3 ～ 12.5μm, Uburinganire burashobora kugera kuri CT7 ～ CT9;gusenyuka nibyiza, kandi gukina biroroshye gusukura.

2. Igipimo cyo gusaba

Umusenyi utwikiriye urashobora gukoreshwa mugukora ibishishwa hamwe numusenyi.Ibishushanyo cyangwa ibice byumucanga bitwikiriye birashobora gukoreshwa bifatanije cyangwa hamwe nundi mucanga (cores);ntishobora gukoreshwa gusa mubyuma bikurura imbaraga cyangwa guta umuvuduko muke, ariko kandi irashobora gukoreshwa muguterera ibyuma byumusenyi hamwe no guta ubushyuhe bwa centrifugal;ntishobora gukoreshwa gusa mu gukora ibyuma bikozwe mu byuma na fer idafite ferrous, ariko no mu gukora ibyuma.

II.Gutegura umucanga usize

1. Ibigize umucanga usize

Mubusanzwe igizwe nibikoresho byangiritse, binders, imiti ikiza, amavuta hamwe ninyongera zidasanzwe.

2. Uburyo bwo kubyara umucanga utwikiriye

Igikorwa cyo gutegura umucanga utwikiriye ahanini gikubiyemo ubukonje bukonje, gutwika ubushyuhe, hamwe nubushyuhe.Kugeza ubu, umusaruro wose wumucanga utwikiriye ukoresha uburyo bushyushye.

3. Ubwoko bwibanze bwibicuruzwa byumucanga

(1) Umusenyi usanzwe usanzwe ni umucanga usanzwe

)

Ibiranga: imbaraga nyinshi, kwaguka gake, gaze nkeya, gazi gahoro, anti-okiside

(3) Ubushyuhe bwo hejuru (ubwoko) butwikiriwe n'umusenyi (ubwoko bwa ND)

Ibiranga: kurwanya ubushyuhe bwinshi, imbaraga nyinshi, kwaguka gake, gaze nkeya, gazi gahoro, byoroshye gusenyuka, anti-okiside

(4) Byoroshye kugwa umusenyi utwikiriwe

Ifite imbaraga nziza nubushyuhe bwo hasi cyane bwo gusenyuka, bikwiranye no gukora ibyuma bidafite fer.

(5) Ibindi bidasanzwe bisabwa umusenyi.

III.Inzira nyamukuru yo gukora intoki hamwe n'umucanga usize

Ubushyuhe bwo gushyuha ni 200-300 ℃, igihe cyo gukira ni 30-150, naho umuvuduko wo kurasa umucanga ni 0.15-0.60MPa.Kumusenyi wumusenyi ufite imiterere yoroshye hamwe numusenyi utwikiriye ufite amazi meza, umuvuduko wo kurasa urashobora guhitamo.Kumusenyi muto, ubushyuhe bwo hasi burashobora gutoranywa.Iyo ubushyuhe bwo gushyuha buri hasi, igihe cyo gukira kirashobora kongerwa muburyo bukwiye.Ibisigarira bikoreshwa mumucanga usize ni fenolike.Ibyiza byuburyo bukora: gukora imbaraga zikwiye;amazi meza;uburinganire bwiza bwubutaka bwumucanga (Ra = 6.3-12.5μm);ubukonje bukomeye bwumusenyi;gusenyuka neza no gusukura byoroshye gukina.

1. Ubushyuhe (mold)

Ubushyuhe bwububiko nimwe mubintu byingenzi bigira ingaruka kumubyimba nimbaraga zurwego rwigikonoshwa, mubisanzwe bigenzurwa kuri 220 ～ 260 ℃

2. Umuvuduko wo kurasa umucanga nigihe

Igihe cyo kurasa umucanga muri rusange kigenzurwa kuri 3 ～ 10s.Niba igihe ari gito cyane, ifu yumucanga (intangiriro) ntishobora gushingwa.Umuvuduko wo kurasa umucanga muri rusange ni 0,6MPa;iyo igitutu ari gito cyane, biroroshye gutera kurasa bidahagije cyangwa kurekura.Igihe cyo gukomera: Uburebure bwigihe cyo gukomera biterwa ahanini nubunini bwumusenyi wumusenyi (intangiriro) nubushyuhe bwububiko, muri rusange hafi 60-120.

Kugeza ubu, ibicuruzwa byacu byingenzi ni ibyuma byoroha byuma byuma, ibyuma bifata ibyuma, imiyoboro ikomatanya, guhuza ikirere, guhuza ibyuma bibiri, amashanyarazi ya bolt imwe, gufatira hamwe, kwihuta, umubiri wumuyoboro, insina za KC, gusana hose hamwe n’ibirenga amagana. ibicuruzwa kugirango uhitemo.Murakaza neza kuri Donghuan Malleable Iron casting kubaza, tuzabikuye ku mutima serivisi zanyu.
