Taw qhia
"Low-aluminium ferrosilicon" suab zoo li nws yog txhua yam hais txog txhuas, tab sis hauv kev siv tiag tiag cov qib silicon tseem ceeb npaum li cas. Yog vim li cas ntau specs tsom rau75% (FeSi75)yog tias nws muab kev huv, tswj tau ntau txoj hauv kev xa cov silicon thaum khaws txhuas nruj nruj. Yog tias cov ntsiab lus silicon poob qis dhau lawm, koj feem ntau xaus rau kev ntxiv cov khoom siv kom ncav cuag cov txiaj ntsig zoo ib yam - thiab qhov ntawd tuaj yeem ua rau kev tswj tsis huv nyuaj, tsis yooj yim dua.
Hauv qab no yog cov lus piav qhia siv tau hauv Q&A daim ntawv, yam tsis tau txais kev tshaj lij.
Khoom Description
Q1: "75% purity" txhais li cas ntawm no -peb tham txog cov ntsiab lus silicon?
Yog lawm. Hauv kev lag luam ferrosilicon, "75%" feem ntau yog hais txogcov ntsiab lus silicon, tsis yog lab-style "purity" zoo li kws tshuaj. Yog li FeSi75 txhais tau hais tias cov alloy yog kwv yees li 75% silicon, nrog rau qhov seem feem ntau yog hlau ntxiv rau me me ntawm lwm cov ntsiab lus.
Thaum ib yam khoom tau piav raws liqis -Aluminium FeSi75, nws yog qhov tseem ceeb hais tias:
siab silicon (kwv yees li 75%), thiab
aluminium yog tswj hauv qab qhov kev txwv nruj dua li tus qauv FeSi.
Q2: Vim li cas 75% silicon qib tseem ceeb heev thaum lub hom phiaj tseem ceeb yog "tsawg txhuas"?
Vim tias cov ntsiab lus silicon hloov ntau npaum li cas cov khoom koj xav tau ntxiv.
Yog tias silicon siab (FeSi75), koj tuaj yeem ncav cuag koj lub hom phiaj silicon nrogib qho me me ntxiv. Qhov ntawd muaj ob qhov txiaj ntsig zoo:
nws khaws cov txheej txheem ntau dua (tsawg dua tag nrho cov alloy ntxiv), thiab
nws txo txoj hauv kev "nqa" cov khoom tsis xav tau ntxiv -aluminium suav nrog.
Yog tias koj siv qib silicon qis dua, koj feem ntau xav tau ntau dua li cov hlau nplaum kom ncav cuag tib qhov kawg silicon hauv cov hlau lossis hlau. Txawm hais tias qib qis no tau tshaj tawm raws li "Low Al," qhov ntau npaum li cas tuaj yeem ua rau kev tswj tsis huv.
Q3: FeSi75 pab tau li cas hauv kev tsim khoom?
FeSi75 tau siv dav ib feem vim nws nyiam coj tus cwj pwm ruaj khov: nws dissolves kwv yees, xa cov silicon zoo, thiab tso cai rau kev tswj cov tshuaj lom neeg nruj dua.
Hauv ntau qhov haujlwm, "kev pheej hmoo zoo" tsis yog hais txog tus nqi nruab nrab ntawm COA - nws yog hais txog kev hloov pauv. Ib qho ruaj khov FeSi75 muab kev pab txo qis:
loj viav vias hauv silicon rov qab
qhov yuav tsum tau rov kho dua
chemistry overshoot (ntxiv ntau dhau, ces them nyiaj tom qab)
Qhov kev ruaj ntseg zoo li no tshwj xeeb tshaj yog muaj nuj nqis hauv cov ntawv thov uas aluminium yuav tsum nyob qis thiab tswj tau.
Q4: Puas muaj kev sib txuas ntawm cov txhuas tsis tshua muaj hlau thiab cov hlau huv huv?
Feem ntau, yog. Aluminium tsis yog "phem" nyob rau hauv tag nrho cov steelmaking, tab sis nyob rau hauv tej yam txheej txheem nws ua ib tug rhiab variable. Yog tias aluminium nce siab tsis xav txog, nws tuaj yeem cuam tshuam kev coj tus cwj pwm thiab kev huv tag nrho. Tias yog vim li cas qee cov neeg yuav khoom hais kom qis - txhuas FeSi75: lawv xav tau silicon ntxiv yam tsis tau qhia txog qhov sib txawv ntxiv.
Hauv cov xwm txheej ntawd, FeSi75 tsis hloov cov txheej txheem tswj tau zoo-tab sis nws ua kom tswj tau yooj yim dua. Nws yog ib qho tsawg dua los sib ntaus.
Q5: Dab tsi yuav tsum tau kuaj xyuas hauv qis-Al FeSi75 tshwj xeeb ntxiv rau Si thiab Al?
Si thiab Al yog cov ntawv xov xwm, tab sis feem ntau cov specs kuj them rau:
P (phosphorus)thiabS (sulfur), tshwj xeeb tshaj yog rau cov kev cai huv huv
C (carbon)yog tias cov pa roj carbon sib npaug yog rhiab heev
particle loj(lump vs granule), vim nws cuam tshuam rau melting ceev thiab rov qab
shipping thiab ntim cov ntsiab lus, tshwj xeeb tshaj yog rau qhov me me qhov twg noo noo thiab nplua teeb meem
Qhov zoo "qis-aluminium" tsis yog hais txog kev ntaus tus lej Al ib zaug; nws yog hais txog kev xa cov khoom sib xws raws sijhawm.
Hais txog peb cov khoom
Peb muabTsawg-Al FeSi75nrog cov ntsiab lus silicon ruaj khov, tswj cov qib txhuas, thiab hloov pauv qhov loj me xws li pob thiab granules. Yog tias koj qhia koj daim ntawv thov thiab koj lub hom phiaj Al txwv, peb tuaj yeem muab COAs tsis ntev los no, sib tham txog qhov loj me, thiab paub meej tias FOB thauj khoom tam sim no los ntawm cov chaw nres nkoj loj hauv Suav.
