Ferro Silicon Barium

Barium silicon inoculant, yooj yim muab, yog qhov qub75% ferrosilicon hmoovnrog ntxiv barium (Ba). Dab tsi yog qhov txiaj ntsig ntawm kev ntxiv barium? Tsuas yog ib qho: nws prolongs cov nyhuv inoculation.

Nrog zoo tib yamferrosilicon inoculation, cov nyhuv diminishes lub sij hawm los ntawm kev ua mus rau qhov kawg pouring ntawm cov hlau molten. Ferro Barium silicon inoculant tuaj yeem txuas lub sijhawm ua haujlwm tau zoo los ntawm ntau dua ob npaug, ua rau nws tsim tshwj xeeb rau kev ua ladle, lub sijhawm nchuav ntev, lossis tsim cov tuab -section castings. Hauv peb txoj kev lag luam, peb hu nws ua "ntev - ntev inoculant." Yog tias koj ntsib teeb meem xws li inoculation degradation, tsis sib luag graphite loj, los yog dawb cam khwb cia hlau tsim nyob rau hauv nyias -walled seem, barium silicon inoculant yog tsim tshwj xeeb los daws cov teeb meem no.

Feem ntau siv inoculants tsis muaj dab tsi ntau tshaj li ferrosilicon 75% thiab barium silicon. Qhov txawv ntawm ob qho no yog dab tsi? Cia kuv qhia koj qee yam uas koj tuaj yeem paub txog ntawm -site:

Ordinary ferrosilicon75:Thaum ntxiv, cov nyhuv yog zoo pib, nrog ntau graphite nuclei. Tab sis tom qab 10 lossis 15 feeb, cov nyhuv pib poob qis. Yog hais tias lub ladle loj thiab lub pouring qeeb, qhov zoo ntawm cov tom qab- poured castings yuav qis dua qhov ua ntej lawm - poured sawv daws yuav.

Barium silicon inoculant:Vim yog cov barium ntxiv, lub nucleus decays qeeb dua. Nrog tib lub ladle ntawm molten hlau, cov nyhuv inoculant tseem ruaj khov txawm tias nyob rau hauv ib nrab ntawm cov txheej txheem pouring.

Cov lus teev ntau qib ntawm basi inoculant, nrog cov ntsiab lus barium xws li 2% txog 30%. Nov yog daim ntawv qhia rau koj:

Ordinary grey hlau thiab ductile hlau:2%-5% Ba yog txaus, muab cov txiaj ntsig zoo.

Loj -batch processing (piv txwv li, ladles tshaj 5 tons):10% -15% Ba yog pom zoo kom muaj zog tiv thaiv kom lwj.

Rau castings nrog tshwj xeeb stringent yuav tsum (xws li cua turbines thiab pwm loj):xav txog kev siv cov ntsiab lus Ba ntawm 20% -30% kom ntseeg tau tias qhov kawg casting yog qhov zoo.

Tsis tas li ntawd, qhov loj me kuj tseem ceeb heev. Siv 1-3mm particles rau inoculation nyob rau hauv lub casting trough, thiab 0.2-0.7mm hmoov zoo rau inoculation inoculation.

1. daws teeb meem Inoculation Decline (Feem ntau daim ntawv thov)

Ntau tus neeg ua haujlwm hauv lub tuam tsev tsis txaus siab rau peb, "Kuv muaj 5-tuj ladle ntawm cov hlau molten, txaus rau ib lub kaum lossis ntau qhov chaw. Cov khoom ua ntej no zoo rau lub tshuab, tab sis cov tom qab ntawd nyuaj dhau lawm." Qhov no yog ib qho piv txwv ntawm inoculation poob. Tom qab hloov mus rau barium silicate inoculation, tom qab-cam khwb cia qhov chaw thiab nyiam cov hlau dawb tsim yog txo qis, thiab hardness yog ntau dua. Qhov no yog cov nyhuv ntawm barium silicate.

2. Txhim kho hlau dawb

Ua hauv Nyias-Walled Castings Qee qhov castings muaj cov phab ntsa nyias (xws li, tsawg dua 5 hli). Thaum siv cov ferrosilicon zoo tib yam inoculation, dawb hlau tsim tau yooj yim tshwm sim ntawm cov npoo thiab cov ces kaum, xav tau cov cuab yeej machining. Siv barium silicate (tshwj xeeb tshaj yog cov hmoov zoo hauv cov dej ntws), qhov dav ntawm cov hlau dawb tuaj yeem raug txo los ntawm ib nrab, thiab nyias - cov phab ntsa tuaj yeem ua tau zoo.

3. Nce Graphite Nodules (Ductile Iron)

Cov neeg ua haujlwm nrog cov hlau nplaum paub tias qhov siab dua thiab zoo dua cov graphite nodules, qhov zoo dua lub zog thiab elongation ntawm cov hlau ductile. Barium silicate inoculators tuaj yeem tsim 30% -50% ntau graphite nodules dua li cov ferrosilicon zoo tib yam, uas zoo heev pab txhim kho qhov zoo ntawm cov hlau.

4. Loj, tuab -section castings:

Cheebtsam xws li cua turbine hubs thiab pwm loj yuav tsum tau ntev casting lub sij hawm thiab qeeb core txias, yuav tsum muaj siab tiv thaiv degradation nyob rau hauv lub inoculant. Barium silicon (tshwj xeeb yog siab- qib barium) yog tus qauv rau cov castings no.

Q: Ntau npaum li cas kim dua barium silicon piv rau li niaj zaus 75% ferrosilicon? Puas tsim nyog nws?

A: Barium silicon tiag tiag kim dua li niaj zaus 75% ferrosilicon (tus nqi tseeb nyob ntawm cov ntsiab lus barium). Txawm li cas los xij, seb nws puas tsim nyog nws nyob ntawm tus nqi tag nrho. Siv barium silicon txo cov seem seem, ua rau cov castings zoo ib yam nyob rau hauv hardness, thiab tshem tawm qhov yuav tsum tau rau kev sib cais ntawm ncej- cam khwb cia qhov chaw, txuag ntau tshaj li tus nqi sib txawv.

Q: Kuv xav ua hauv -flow inoculation; Kuv yuav tsum siv barium silicon lossis ferrosilicon li niaj zaus?

A: Hauv -flow inoculation qhia txog qhov "instantaneous" nyhuv; cov hmoov zoo dissolves tag nrho hauv vib nas this, feem ntau nyob ntawm nws lub peev xwm los tsim graphite nuclei. Ob qho tib si ferrosilicon thiab barium silicon zoo. Txawm li cas los xij, yog tias koj lub ladle hlau molten loj, lub sij hawm pouring yog ntev, los yog koj muaj ntau nyias -walled qhov chaw, barium silicon muaj qhov zoo dua - nws tsis yog tsuas yog siv tau tam sim ntawd tab sis kuj muaj ntev - cov khoom kav ntev.

Q: Puas yog qhov zoo ntawm koj cov barium silicon zoo ib yam ntawm cov khoom siv?

A:Kev sib raug zoo yog qhov tseem ceeb. Ua ntej txhua pawg ntawm cov khoom tawm ntawm lub Hoobkas, peb siv lub spectrometer los tshuaj xyuas cov khoom muaj pes tsawg leeg, kom ntseeg tau tias qhov kev hloov pauv ntawm barium thiab silicon cov ntsiab lus yog tswj nyob rau hauv ib qho me me. Daim ntawv pov thawj cov ntaub ntawv suav nrog cov khoom, thiab koj tuaj yeem ua qhov kev kuaj xyuas koj tus kheej.
