Ob qib Silicon, Ob txoj haujlwm sib txawv heev
Silicon hlau 2202 thiab ferrosilicon 72 yog ob qho tib si silicon -cov khoom siv hlau uas muag rau hauv steelmaking, casting thiab downstream manufacturing, tab sis lawv tsis hloov pauv. Ib qho yog refined, siab -purity khoom siv qhov twg silicon nws tus kheej yog cov khoom; lwm yam yog ib tug master alloy uas nws txoj hauj lwm yog xa silicon thiab hlau ua ke rau hauv molten hlau los yog hlau. Sib piv lawv yog li ntawd txhais tau hais tias sib piv cov muaj pes tsawg leeg, ntau lawm txoj kev, particle loj thiab daim ntawv thov es tsis yog ib tug headline feem pua.
Cov lus nug ua tau tom qab qhov kev sib piv feem ntau yog nyiaj txiag. Ferrosilicon yog tus nqi qis dua -txoj kev uas yuav ntxiv silicon rau yaj, thaum silicon hlau tau teev tsuas yog qhov seem hlau, txhuas thiab calcium uas ferrosilicon nqa nrog nws yuav ua rau cov khoom tiav.
Kev sau npe thiab qib npe
Silicon hlau yog tsim los ntawm plaub tus lej - tus lej code uas txhua tus lej ntawm tus lej qhia qhov siab tshaj plaws hlau, txhuas thiab calcium cov ntsiab lus hauv ntau pua ntawm ib feem pua. Qib 2202 yog li ntawd txhais tau hais tias hlau mus txog 0.20%, txhuas mus txog 0.20% thiab calcium mus txog 0.02%, nrog silicon ua kom sib npaug ntawm 99.5% lossis ntau dua. Suav silicon hlau feem ntau yog muab los ntawm GB / T 2881, uas teev cov tshuaj uas yuav tsum tau rau cov qib lag luam thiab lawv cov feem me me.
Ferrosilicon yog tsim los ntawm nws cov ntsiab lus silicon raws li tus lej tag nrho. Qib 72 muaj kwv yees li 72% silicon nrog qhov sib npaug ntawm cov hlau, ntxiv rau cov tshuaj txhuas, calcium, sulfur thiab phosphorus. Suav ferrosilicon ib txwm muab tawm tsam GB / T 2272, uas txhais cov npe qib nrog rau lawv cov kev txwv tsis pub muaj. Ib daim duab silicon yog li tsis txaus los sib piv ob yam khoom: hauv qab kab ntawd, cov kev txwv tsis pub txiav txim siab uas cov txheej txheem hauv qab yuav txais cov khoom siv.
Txoj kev tsim khoom
Silicon hlau 2202 yog tsim los ntawm kev txo cov quartz nrog cov pa roj carbon reductant nyob rau hauv hluav taws xob arc rauv, ces refining lub molten silicon kom hlau, txhuas thiab calcium poob nyob rau hauv lub 2202 maxima. Cov hlau refined yog cam khwb cia rau hauv ingots, crushed thiab soj ntsuam mus rau qhov yuav tsum tau muaj ntau yam.
Ferrosilicon 72 yog tsim los ntawm siab -kub txo ntawm silica nrog coke thiab ib qho chaw hlau nyob rau hauv lub submerged arc rauv, feem ntau ua hauj lwm nyob rau hauv lub 1500-2000℃ntau yam, thiaj li hais tias silicon thiab hlau alloy nyob rau hauv lub cub tawg. Cov hlau yog tapping, txias, crushed thiab loj. Qhov sib txawv ntawm txoj kev piav qhia feem ntau ntawm tus nqi sib txawv: silicon hlau nqa tus nqi ntawm kev ua kom zoo ntxiv kom ncav cuag 99.5% silicon, hos ferrosilicon txhob txwm ua kom nws cov ntsiab lus hlau.

Kev xaiv ua raws ncaj qha los ntawm cov luag haujlwm ntawd. Xaiv ferrosilicon 72 thaum silicon yog ib qho khoom siv rau hlau lossis hlau chemistry thiab tus nqi ntawm ib chav tsev ntawm silicon tswj qhov kev txiav txim. Xaiv cov hlau silicon 2202 thaum yaj lossis cov khoom kawg tsis tuaj yeem zam cov txhuas, calcium thiab hlau uas nrog ferrosilicon, xws li hauv aluminium alloying, hnub ci - qib feedstock thiab cov khoom siv hluav taws xob.
Vim tias ob qho tib si cov khoom lag luam raug muag los ntawm cov tshuaj muaj pes tsawg leeg thiab cov khoom me me, kev tshuaj xyuas cov khoom xa tuaj ib txwm sib txuas cov tshuaj ntsuam xyuas ntawm txhua lub tshav kub nrog rau kev tshuaj ntsuam xyuas qhov loj me, thiab ntim khoom yog tsim los kom cov khoom qhuav qhuav: cov hnab ntim dej tsis muaj dej ntawm 10 kg lossis 25 kg hauv 1 MT bulk hnab, nrog rau lwm cov kev teeb tsa tsim tawm raws li kev pom zoo.
FAQ
Q: Puas tuaj yeem ferrosilicon 72 siv los hloov silicon hlau 2202?
Feem ntau tsis muaj. Ferrosilicon coj kwv yees li 28% hlau ntxiv rau aluminium thiab calcium ntau dua, yog li nws tsis tuaj yeem ua tau raws li qhov kev txwv tsis pub muaj kev txwv uas txhais tau qib 2202 lossis purity yuav tsum tau siv hnub ci, hluav taws xob thiab aluminium alloy.
Q: Cov lej hauv silicon hlau qib 2202 txhais li cas?
Lawv yog cov impurity siab tshaj plaws nyob rau hauv pua pua ntawm ib feem pua, nyob rau hauv kev txiav txim hlau, txhuas thiab calcium: hlau 0.20%, aluminium 0.20% thiab calcium 0.02%, nrog silicon 99.5% yam tsawg kawg nkaus.
Q: Qib twg yog siv rau deoxidising steel?
Ferrosilicon, feem ntau yog qib 72 lossis 75, yog tus qauv deoxidation ntxiv. Silicon hlau yog siv los hloov tsuas yog thaum cov hlau seem thiab txhuas nws hloov yuav siv tau rau cov yaj.
Q: Vim li cas ferrosilicon muaj ntau cov hlau?
Cov hlau tsis yog impurity yuav tsum tau txo qis; Nws txo qis cov ntsiab lus melting ntawm cov hlau txheeb ze rau cov silicon ntshiab thiab ua tau zoo nrog cov hlau lossis hlau yaj, yog li cov hlau yaj tau yooj yim thiab xa cov silicon zoo.
Q: Puas yog qhov loj me ntawm cov khoom sib hloov pauv tau?
Tsis yog. Silicon hlau yog ib txwm nkag rau hauv ntxhib 10-100 mm lumps rau melting los yog crushing, whereas ferrosilicon feem ntau nkag finer, feem ntau 0-10 hli, kom nws disperses sai sai nyob rau hauv da dej los yog nyob rau hauv ib tug casting inoculant kwj.
Q: Yuav ua li cas yog qhov zoo ntawm kev xa khoom xa tuaj?
Los ntawm tshuaj ntsuam xyuas ntawm txhua qhov cua sov rau silicon, hlau, txhuas, calcium, sulfur thiab phosphorus raws li muaj feem xyuam, txhawb nqa los ntawm kev tshuaj ntsuam me me thiab los ntawm kev ntim khoom uas ua rau cov khoom qhuav hauv kev thauj mus los thiab cia.
