GGG60 pob zeb cam khwb cia hlau poob ciab peev casting
GGG60 tshuaj muaj pes tsawg leeg
GGG60 tshuaj muaj pes tsawg leeg feem ntau suav nrog:
Cov pa roj carbon C: 0.50 ~ 4.00
Silicon Si: 2.0-2.5
Manganese Mn: {{0}}.40 txog 0.80
Sulfur S: Ntau dua lossis sib npaug rau 0.06
Phosphorus P: Ntau dua lossis sib npaug rau 0.02

Tsis tas li ntawd, muaj cov khoom ntawm alloy cam khwb cia hlau, xws li:
Keeb kwm: Ntshuam, domestic
Cov ntsiab lus carbon: 3.2%
Silicon cov ntsiab lus: 2.0%
Cov ntsiab lus phosphorus: 0.10%

Cov Cheebtsam thiab cov yam ntxwv no ua rau GGG60 muaj cov khoom siv tshuab siab, xws li lub zog tensile σb (MPa): Ntau dua lossis sib npaug li 600, lub zog muaj zog σ0.2 (MPa): Ntau dua lossis sib npaug rau 370, elongation δ (%): Ntau dua lossis sib npaug rau 3, hardness: 192 ~ 269HB
Kev nqis peev Casting feem ntau yog ua los ntawm cov peev txheej molding cov ntaub ntawv (cov ntaub ntawv uas tsis tshua muaj melting point, xws li siv quav ciab, thiab lwm yam) los tsim pwm, thiab tom qab ntawd ob peb txheej ntawm cov ntaub ntawv refractory yog coated rau saum npoo ntawm pwm. Tom qab hardening, ziab thiab kho, cov pwm yog rhuab kom yaj tawm cov pwm los ua ib lub plhaub hollow, thiab cov kua hlau yog poured tom qab sintering ntawm qhov kub thiab txias.
Vim yog qhov siab qhov tseeb thiab qhov chaw tiav ntawm cov castings tau txais, peev casting tseem hu ua "kev nqis peev precision casting".
Nyob rau tib lub sijhawm, vim tias cov khoom siv peev feem ntau yog cov khoom siv siv quav ciab, nws tseem hu ua "Lost Wax Casting".
Kev nqis peev casting yog ib qho kev ua tiav nyob ze-net tsim cov txheej txheem uas tuaj yeem tsim cov precision, complex castings ntawm ntau yam alloys uas nyob ze rau qhov kawg cov duab thiab qhov loj ntawm qhov, thiab tuaj yeem siv ncaj qha lossis nrog me me machining.

Kev nqis peev casting txheej txheem

Kev nqis peev casting muaj rau lub ntsiab txheej txheem
Wax molding -> Tree formation -> Shell making -> dewaxing and roasting -> smelting and pouring ->xuab zeb clearing thiab txiav kom tau cov khoom tiav.
1.1 Ciab molding
Ciab molding, yog nias cov khoom siv quav ciab rau hauv pwm kab noj hniav, txias tawm los ua ib qho pwm.

1.2 Pawg Tsob Ntoo

Yuav kom tsim tau ib tsob ntoo, ntau wax pwm yog welded rau lub pouring system.

1.3 Kev ua lub plhaub

Plhaub ua, yog thawj zaug dipped rau saum npoo ntawm cov quav ciab pwm nrog ib tug zoo silica sol txheej, thiab ces sprinkle refractory xuab zeb, lub plhaub yog qhuav thiab hardened nyob rau hauv tshwj xeeb kub thiab av noo, thiaj li hais tias ib tug tuab refractory txheej yog tsim nyob rau saum npoo. cov wax pwm, thiab tom qab ntawd rov ua cov txheej txheem 5-6 zaug, thiab thaum kawg tsim nrog qee lub zog thiab refractoriness ntawm silica sol plhaub.

1.4 Dewaxing thiab ci

Dewaxing yog siv quav ciab hauv lub plhaub los ntawm qhov kub kub kom yaj cov quav ciab tawm, kom koj tuaj yeem tau txais cov kab noj hniav pwm uas tuaj yeem nrum.

Plhaub roasting yog tsuas yog los hlawv cov seem seem thiab dej hauv lub plhaub pwm, thaum precision casting yog cam khwb cia hauv lub plhaub liab, feem ntau lub plhaub pwm yog roasted ntawm txog 1000 degrees rau 1-2 teev.

1.5 Smelting thiab pouring

Raws li cov khoom muaj pes tsawg leeg ntawm cov khoom, thiab tom qab ntawd molten steel melting, slag spectrum test, muaj pes tsawg leeg tuaj yeem nchuav tom qab tsim nyog. Nws yog tsim nyog los ncuav molten hlau mus rau hauv lub puab plhaub nyob rau hauv nruj raws li qhov yuav tsum tau ntawm daim card txheej txheem nyob rau hauv lub liab plhaub xeev kom maj mam tsim ib tug dawb paug.

1.6 Xuab zeb tu, txiav kom tau cov khoom tiav

Tom qab qhov khoob uas tau txais tom qab pouring yog tag nrho txias, lub plhaub pwm yog sib cais los ntawm cov dawb paug siv phau ntawv (rauj) los yog vibration sheller, thiab ces lub casting yog txiav thiab sib cais los ntawm lub pouring system kom tau cov tiav casting.

Tom qab polishing, machining thiab lwm yam txheej txheem tuaj yeem ua raws li qhov xav tau.

Cov txheej txheem ntawm kev nqis peev casting tuaj yeem raug xa mus rau cov yeeb yaj kiab hauv qab no hauv tib tsab xov xwm ntawm pej xeem tus account ntawm tib lub npe.
