Kev Siv Tshuab

Stainless hlau silica sol casting ua tshuab: stainless hlau precision casting ua yog ib qho tseem ceeb hauv kev siv tshuab hauv kev lag luam machinery thiab occupies ib qho tseem ceeb txoj hauj lwm nyob rau hauv lub teb chaws kev khwv nyiaj txiag. Tam sim no, kev tshawb fawb ywj pheej thiab kev loj hlob tau dhau los ua lub hom phiaj tseem ceeb ntawm txoj kev loj hlob ntawm domestic foundry tuam txhab. Tawm ntawm txoj kev hloov pauv ntawm stainless hlau precision casting casting.

Raws li ob peb hom kev pressurization nyob rau hauv lub pressurization specification thaum lub sij hawm ua cov stainless hlau castings, lub pressurization ceev yuav ua tau nws cov kev xav tau sib txawv raws li txhua theem ntawm cov txheej txheem casting.

(1) Literal theem.

Qhov nce qib ntawm cov hlau molten tsuas yog theem npaj ua ntej sau. Txhawm rau ua kom cov hlau molten nyob rau hauv cov txheej txheem ntawm compressing qhov chaw ntawm kab noj hniav, nws yog qhov tsim nyog rau cov pa tawm ntawm cov pa tawm hauv cov kab noj hniav los ntawm cov kav dej, yog li cov hlau molten yuav tsum khaws cia kom siab li ntau tau. Cov yeeb nkab ua kua nce maj mam, thiab nws qhov kev nce ceev yuav tsum tau tswj ntawm li 50mm / s. Txhawm rau kom tau txais cov kua dej nce ntxiv no, qhov xav tau qhov ntsuas siab yog 0.0014 MPa / s.

(2) Filling theem.

Tom qab cov hlau molten nce mus rau qhov system casting, nws pib nkag mus rau theem filling.

① Thick-walled castings. Vim yog cov phab ntsa tuab ntawm cov casting, kev sau thiab kev tsim ntawm cov casting tsis yog ib qho kev sib txuas, yog li cov hlau molten tuaj yeem txuas ntxiv mus rau ntawm qhov nrawm ntawm 50mm / s kom ntseeg tau tias qhov kev tso tawm zoo ntawm gas nyob rau hauv lub casting pwm. Nws lub siab ceev sib raug yog 0.0014MPa / s.

② nyias-walled castings. Thaum cov phab ntsa thickness ntawm lub casting yog me me, yog hais tias lub filling ceev ntawm lub molten hlau yog qeeb heev, nws yog ib qho yooj yim mus ua defects xws li tsis meej cov qauv ntawm lub casting, txias sib cais, thiab nyob rau hauv lub pouring. Yog li ntawd, rau nyias-walled castings, lub filling ceev yuav tsum siab tshaj cov kua lifting ceev. Qhov kev txhim kho qib yog nyob ntawm qhov txias txias ntawm pwm.

Nyob rau hauv qhov tseeb ntau lawm, lub filling ceev ntawm nyias-walled castings yuav tsum tau txiav txim raws li qhov sib txawv kub dissipation tej yam kev mob ntawm castings. Nws tseem yuav tsum tau ua kom paub tseeb tias qhov ntim ceev tuaj yeem ua kom qeeb raws li qhov ua tau ntawm qhov chaw ntawm kev tau txais kev txiav tawm kom pom tseeb.

Kev kho cua sov

Stainless hlau silica sol casting txheej txheem kev kho cua sov

Siv martensitic stainless hlau ua piv txwv:

Dab tsi yog cov yam ntxwv ntawm kev kho cua sov ntawm martensitic stainless hlau?

Martensitic stainless hlau muaj xws li Cr13 hom (tsawg carbon thiab nruab nrab carbon), Cr17Ni hom (tsawg carbon), Cr18 hom (high carbon), thiab nws cov txheej txheem kev kho cua sov muaj xws li annealing, quenching ntxiv tempering, kev nyuaj siab nyem, thiab lwm yam.

(1) Cr13 stainless hlau:

Nws tuaj yeem pom los ntawm daim duab qhia theem (Daim duab 8-1) tias cov hlau alloy nrog Cr Ntau dua lossis sib npaug li 12 feem pua ​​​​muaj cov khoom ntawm stainless hlau thiab tuaj yeem quenched thiab ntxiv dag zog. Cov qauv ferrite muaj nyob rau hauv cov qauv austenitized, uas yog khaws cia tom qab quenching. Yog tias cov ntsiab lus Cr siab dhau lawm, ib-theem ferrite yuav raug tsim thaum rhuab, thiab kev kho quenching thiab ntxiv dag zog yuav ua tsis tau.

1) Annealing:

Softening annealing tuaj yeem ua tau raws li qhov yuav tsum tau ua rau kev txiav, thiab kev kho cua sov tom qab forging tuaj yeem tiv thaiv kev tawg ntawm forgings, thiab tag nrho annealing yog xav tau rau extrusion deformation.

Muaj ntau ntau ntawm chromium carbide nyob rau hauv lub annealed workpiece, thiab cov ntsiab lus chromium nyob rau hauv cov khoom siv txo. Nyob rau tib lub sijhawm, cov chromium carbide hais thiab cov matrix tsim ntau lub roj teeb micro, uas ua rau lub zog ntawm corrosion ntawm steel qhov chaw.

Kev sib raug zoo ntawm quenching hardness ntawm 1Cr13 thiab cov ntsiab lus carbon yog qhov loj. Thaum cov ntsiab lus carbon ntau dua lossis sib npaug rau 0.13 feem pua ​​​​thiab cov ntsiab lus chromium ntau dua lossis sib npaug li 12.75 feem pua, qhov hardness ntau dua 46. 5HRC. Lub quenching hardness ntawm 2Cr13 yog hais txog 50HRC. Lub hardness ntawm 3Crl3 thiab 4Crl3 steel tom qab quenching yog 51 ~ 56HRC.

2) Tempering tom qab quenching:

Qhov kub quenching ntawm 1Cr13 yog 1000-1050 degree, 2Cr13 feem ntau yog 980-1000 degree, thiab tempering kub ntawm 1Cr13 thiab 2Cr13 feem ntau yog 600-700 degree .

Rau cov qauv tsim kev cai ntawm 1Cr13, sim tsis txhob xaiv qhov nyuaj ntawm 40 ~ 43HRC (401HB). Nyob rau hauv no hardness ntau yam, lub tempering kub thiab lub sij hawm tom qab quenching yog ib qho nyuaj rau tswj, raws li qhia nyob rau hauv daim duab 8-2, yog hais tias nws yuav tsum tau xaiv nyob rau hauv no ntau yam Thaum lub hardness nyob rau hauv qhov ntau, qhov kev kho cua sov thiab quenching kub yuav tsum. raug txo kom raws li, tab sis kev tswj qhov nyuaj hauv kev tsim khoom tiag tiag tseem loj heev.

Thib ob, txo cov cua kub ntawm austenite yuav cuam tshuam rau cov khoom siv ntawm cov carbides, thiab qhov cuam tshuam kev ua haujlwm kuj tseem qis, raws li pom hauv daim duab 8-3.

Thib peb, thaum lub tempering kub yog 500-600 degree, carbides nrog ib tug high degree ntawm dispersion yog precipitated nyob rau hauv cov qauv, uas tsis tau tsuas yog tsis muaj corrosion kuj, tab sis kuj tsis tshua muaj tej yam toughness.

Hauv kev tsim khoom tiag tiag, 3Cr13 thiab 4Cr13 muaj qhov kub thiab txias ntawm 1000-1020 degree, qis kub ntawm 200-300 degree, zoo corrosion kuj, thiab tempering hardness ntawm 3Cr13 Ntau dua los yog sib npaug rau 48HRC, 4Cr13 Ntau dua los yog sib npaug li 50 HRC. Kub kub tempering feem ntau yog 600 ~ 750 degree.

Rau Cr13 steel, nws yuav tsum tau tempered nyob rau hauv 8h tom qab quenching kom tsis txhob tawg.
