Lub luag haujlwm ntawm FeSi72 yog dab tsi hauv Grey Hlau Casting li Inoculant?

Txhim kho graphite tsim thiab txo qis txias hauv Grey Hlau

Hauvhlau hlaukev tsim khoom,inoculationtxhais tau hais tias ntxiv nucleants ua ntej casting los txhawb kev nplua, sib npaugHom A graphite flakesthiab rautxo txias(carbide formation) ntawm pwm nto.FeSi72feem ntau siv rau lub hom phiaj no thaum anruab nrab silicon ntxivyog txaus.

Mechanism ntawm FeSi72 li Inoculant

Silicon tso tawm: FeSi72 dissolves nyob rau hauv molten hlau, tsa lub zos Si concentration.

Kev txhawb nqa graphitization: Si tsa qhov kub thiab txias eutectic thiab muab qhov chaw nucleation rau graphite.

Txias txo: Delays carbide tsim nyob rau hauv nyias seem, txhim kho machinability thiab nto tiav.

grain refinement: Txhawb nqa cov graphite zoo dua thiab cov qauv microstructure ntau dua.

Hom Inoculation Parameters rau FeSi72

Parameter	Yam Ntau Yam / Xyaum
Ntxiv sijhawm	Xeem 1-2 feeb ua ntej nchuav (dawb los yog kwj inoculation)
Kev noj tshuaj	0.2-0.5% ntawm yaj hnyav (hloov raws li thawj zaug Si, seem thickness, thiab casting geometry)
Daim ntawv	Crushed 2-10 mm los yog granulated rau sai dissolution
Melt kub	1350-1450℃rau qhov zoo tshaj plaws dissolution
Sib tov	Maj mam nplawm los yog hauv qab pouring kom zoo dispersion

Qhov zoo ntawm FeSi72 Dua Lwm Cov Inoculants

Balanced Si cov ntsiab lus (70-74%)→ Ua kom muaj txiaj ntsig zoo yam tsis muaj Si ntxiv.

Tus nqi efficiency: pheej yig dua ib tuj tshaj FeSi75, txo tus nqi inoculation rau nruab nrab Si hom phiaj.

Tsawg slag tiam: Muab piv rau Sio alloys siab dua, me dua SiO₂ tsim rau tib yam inoculation nyhuv.

Npaj muajnyob rau hauv ntau lub cheeb tsam, tshwj xeeb tshaj yog qhov twg FeSi75 mov yog txwv los yog tshaj-spec rau grey hlau xav tau kev pab.

Cov txiaj ntsig xav tau hauv Grey Hlau

Ntau Hom A graphite, tsawg carbide.

Txo txias qhov tob→ tsawg dua qhov nyuaj, zoo dua machinability.

Txhim kho tensile zog thiab damping muaj peev xwm.

Ntau qhov sib xws mechanical zoghla cov castings.

Cov chaw tsim khoom me me feem ntau ua haujlwm nrogcov peev nyiaj tsawg, me me batch loj, thiabnruj txheej txheem tswjkev xav tau. FeSi72 muaj ntau yamtus nqi-cov txiaj ntsig zoohauv cov kev teeb tsa no.

Tus nqi -Txuag Scenario

Scenario	Vim li cas FeSi72 Yog Tus Nqi -Tswj	Tswv yim tswv yim
Moderate Si inoculation phiaj	Kev ua tiav yuav tsum tau Si boost nrog cov khoom siv tsawg dua FeSi65, tsis txhob siv cov khoom pheej yig dua tab sis tsis muaj zog.	Xam qhov tseeb Si xav tau; siv FeSi72 kom tsis txhob over-inoculation.
Tsis txhob overspecification	FeSi75 tuaj yeem thawb Si dhau qhov xav tau hauv cov hlau kawg, yuav tsum tau dilution lossis ntxiv tuav. FeSi72 muab kev tswj kom zoo nyob ze ntawm 0.2-0.4% ntau yam.	Match qib FeSi72 rau lub hom phiaj Si ntau yam ntawm qib casting.
Tsawg alloy nqi ib tuj	pheej yig dua FeSi75; rau cov cua sov me me, tag nrho cov nqi inoculant yog qhov qis dua.	Yuav hauv ntau me me los yog hnab ntim khoom kom yooj yim tuav.
Txo slag tuav	Tsawg SiO₂ tsim ib chav tsev inoculation nyhuv → me me slag ntim, tsawg refractory hnav, txo nqi tu.	Ua kom zoo ntxiv kom txo qis tom qab nchuav slag tshem tawm haujlwm.
Cov khoom lag luam yooj yim	FeSi72 tuaj yeem ua haujlwm ob lub luag haujlwm (deoxidation hauv qee cov hlau + inoculation nyob rau hauv hlau), txo cov hom alloys khaws cia.	Siv tib cov khoom siv rau ob txoj kev yog tias muaj.
Kev noj tshuaj yooj yim dua	Granulated FeSi72 ntws zoo hauv phau ntawv me me lossis semi-automated feeders.	Siv calibrated daus los yog me me hopper rau kev noj kom zoo ib yam.
