Cov Ntsiab Siv Hauv Steelmaking
Hauv statmaking steel, 0-3 hli silicon calcium alloy ua tus neeg tseem ceeb ntxiv, pab txhim kho cov txheej txheem qub thiab ua tau zoo:
Deagidation ntawm Molten Steel:
Ib qho ntawm thawj siv ntawm 0-3 mi mi} Cov pa dej los ua cov pa roj caricon .0-3 Cov kev pheej hmoo ntawm Regosity loj thiab kev txo qis ntawm cov khoom lag luam roj ntsha kom zoo nkauj thiab kev suav nrog cov khoom kawg.
Desulfurization txhim kho:
Cov tshuaj calcium muaj kev muaj zog rau cov neeg Sulphur, thiab {calcium silicon alloy muaj txiaj ntsig zoo rau cov txiv ntoo uas muaj ntau yam loj ntawm {} mm mm pab txhawb cov khoom faib tsis sib xws hauv Molten Steel, kom meej Sulphur tshem tawm {}}} Cov ntsiab lus sulfur txhim kho xws li kev siv tsheb thiab siv.
Cov muaj kev hloov kho:
Tsis yog xim hlau suav (e {{1} g} mi} mi}}} kev hloov pauv ntawm cov steel qhov kev cuam tshuam tsis kam thiab qaug zog rau lub zog, tseem ceeb rau cov txheej txheem sib xyaw thiab cov tshuab ua kom zoo nkauj kom meej meej kom cov {.
Nodularization hauv cov hlau tshwj xeeb:
Hauv kev tsim cov hlau tshwj xeeb, xws li tsawg-alloy high-mi miece} Kuv zoo tshaj plaws rau cov ntaub ntawv uas yuav tsum tau ua rau cov ntaub ntawv siv hluav taws xob hauv no
Cov ntawv thov hauv cam khwb cia hlau ntau lawm
0-3 mi m m m m puab calcium silicon alloy yog sib luag muaj txiaj ntsig hauv cam khwb cia hlau ntau lawm, qhov uas nws txhim kho castaber castability thiab cov khoom siv tshuab:
Inoculation rau grey cam khwb cia hlau:
Cov xim pob zeb ci ntsa iab rau ntawm tus pas nrig (tawv tawv)} Molten Hlau, muab cov khoom noj muaj txiaj ntsig zoo rau cov pob zeb grey, thiab tshuab cov yeeb nkab, thiab tsev tshiab {}}
Txhim Kho Zas Hlau Zoo:
Zas cov hlau (nodular cam khwb cia hlau) yuav tsum tau spherical graphite rau kev ua kom nruj me ntsis gricite {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} nws tau ua kom muaj kev cuam tshuam rau kev sib tw thiab txo qhov kev pheej hmoo ntawm tej yam tsis xws luag zoo li shrinkage {}} Qhov no ua rau cov hlau sib dhos ua ke xws li Crankshafts thiab lub zog rau.
Txo Casting Distracure:
The 0-3 m m m m m mi miecium silicification thiab cooky {} Nws muaj kev sib xyaw ua ke nws sib xyaw ua ke nrog Molten Hlau, txawm nyob hauv txoj kev ua yeeb yam casting geometries.
Lwm Muaj Kev Siv
Tshaj li cov hlau thiab cov hlau cam khwb cia, {0-3 m mm calcium silicon alloy pom siv hauv cov txheej txheem tshwj xeeb:
Ferrous alloy ntau lawm:
Hauv kev tsim khoom ntawm lwm cov qoob loo ferrous, xws li silicon-mangacey lossis deason}
Vuam Electrode Raug:
Calcium silicon alloy hauv {{mm loj yog ntxiv rau vuam tso rau hauv weld pas dej zoo, thiab txhim kho cov tshuab weld
Hlau Refining Additive:
Nyob rau hauv tsis-ferrous metallgy (e . mi} nws pab tshem tawm cov khoom siv ua kom zoo nkauj thiab cov khoom siv tshuab ua kom zoo nkauj thiab cov khoom siv tshuab hluav taws xob tsis zoo Aerospace Cheebtsam .
Nrhiav tau flux tsim:
Qhov {{0} Lus qib MM yog instry fluxes {} Nws muaj kev cuam tshuam nrog cov hlau nplaum thiab txo qhov tsis xws hauv cov castings.
Vim li cas {0-3 mm loj yog qhov zoo dua
Qhov 0-3 mm loj ntawm calcium silicon alloy muaj cov txiaj ntsig zoo dua ntawm coarser lossis cov qib finer:
Qhov Zoo Tshaj Qhia:
The 0-3 mm loj muab qhov loj thaj chaw rau cov tshuaj tiv thaiv thiab kev ua haujlwm tau ua tiav, thiab ua kom zoo dua qub ua haujlwm thiab txhim kho cov khoom lag luam.
Uniform faib:
Nplua rau nruab nrab granules tsis tshua muaj ntau tusyees hauv cov leeg hlau tsis sib xws hla tag nrho cov txheej txheem kev hloov pauv thiab txhim kho cov khoom lag luam zoo .
Txo cov khib nyiab:
The {{0} Lub sijhawm kawm ntawv MM yog tsawg dua rau cov khoom siv sib dhos thiab ua kom pom qhov txiaj ntsig zoo ib yam thiab ua kom muaj txiaj ntsig zoo nkauj {{2}
Yooj yim ntawm kev tuav:
Thaum cov hmoov nplua nuj yuav tsim cov plua plav thiab ua kev sib tw, {molt {}}}}} kev cuam tshuam rau kev pub mis, txo qis.
