Cov lus piav qhia ntxaws txog kev siv kev ua haujlwm thiab kev ceev faj ntawm inoculant rau casting

Dab tsi yog inoculant?

Inoculant yog ib qho alloyadditive siv los txhim kho cov khoom ntawm cam khwb cia hlau.

Lub luag haujlwm tseem ceeb ntawm cov inoculant yog los txhim kho lub zog, toughness thiab hnav tsis kam ntawm cam khwb cia hlau los ntawm kev txhawb nqa graphitization, txo qhov nyiam ntawm whitening, txhim kho cov morphology thiab kev faib tawm ntawm graphite, nce cov eutectic pawg, thiab kho cov qauv matrix.e.

Inoculants feem ntau yog siv rau hauv cov txheej txheem inoculation ntawm cam khwb cia hlau ntau lawm.Lawv ntxiv rau cov hlau moltenkom sib npaug faib lawv hauv cov cam khwb cia hlau, yog li txhim kho cov khoom ntawm cov cam khwb cia hlau.Hom thiab muaj pes tsawg leeg ntawm inoculants txawv nyob ntawm seb hom cam khwb cia hlau thiab ntau lawm yuav tsum tau.Kev xaiv cov inoculants tsim nyog yog qhov tseem ceeb heev rau kev txhim kho kev ua haujlwm ntawm cam khwb cia hlau.

Tsis tas li ntawd, inoculants kuj tuaj yeem siv rau hauv kev kho mob ntawm cov khoom siv hlau los txhim kho lawv cov kev ua tau zoo thiab cov qauv tsim.

Hom inoculants yog dab tsinyob ntawd?

Cov hom inoculants txawv nyob ntawm lawv cov khoom xyaw thiab siv.Nov yog qee yam hom inoculants:

1. Silicon-raws li inoculant: feem ntau yog ferrosilicon, suav nrog calcium silicon, barium silicon, thiab lwm yam. Hom inoculant no feem ntau ua haujlwm los txhawb graphitization, txo qhov nyiam ntawm whitening, txhim kho morphology thiab kev faib tawm ntawm graphite, nce tus naj npawb ntawm eutectic pawg, kho cov qauv matrix, lwm.

2. Carbon-raws li inoculants: feem ntau yog cov pa roj carbon monoxide, suav nrog cov pa roj carbon tsawg thiab cov pa roj carbon ntau.Hom inoculant no txhim kho cov khoom ntawm cam khwb cia hlau feem ntau los ntawm kev tswj cov ntsiab lus carbon.

3. Tsis tshua muaj lub ntiaj teb inoculant: feem ntau tsis tshua muaj ntiaj teb cov ntsiab lus, xws li cerium, lanthanum, thiab lwm yam. Hom inoculant no muaj lub luag haujlwm ntawm kev txhawb nqa graphitization, refining nplej, thiab txhim kho lub zog, toughness.d hnav tsis kam ntawm cam khwb cia hlau.

4. Compound inoculant: ib qho inoculant uas muaj ntau yam, xws li calcium silicon, barium silicon, tsis tshua muaj ntiaj teb, thiab lwm yam. Hom inoculant no muaj cov nyhuv ntawm ntau lub ntsiab lus thiab tuaj yeem txhim kho cov khoom ntawm cam khwb cia hlau.

Yuav ua li cas siv inoculant

Kev siv inoculants tsuas yog nyob ntawm qhov tshwj xeeb cam khwb cia hlau hom thiab ntau lawm yuav tsum tau.Hauv qab no yog qee txoj hauv kev siv inoculants:

Inoculation nyob rau hauv lub bag: Ntxiv cov inoculant rau hauv lub hnab, ces ncuav rau hauv lub molten hlau kom yaj nws tusyees thiab ces ncuav nws.

Nto inoculation: Sprinkle lub inoculant sib npaug ntawm qhov chaw ntawm cov hlau molten kom nws ua haujlwm sai.

Inoculant sprying: Tom qab diluting lub inoculant nyob rau hauv kev faib ua feem, tshuaj tsuag rau saum npoo ntawm pwm kab noj hniav los ntawm ib rab phom kom nws nkag tau mus rau hauv pwm.

Inoculation thaum lub sij hawm pouring: Muab cov inoculant rau hauv lub tundish, thiab cov hlau molten ntws mus rau hauv pwm kab noj hniav thaum lub sij hawm pouring mus ua si lub luag hauj lwm pub.
