FERRO Siliconyog hu ua "ferrosilicon inoculant" vim tias nws muaj cov kev ua haujlwm ntawm fesi rau cov micrent ntawm cam khwb cia hlau, thiab lwm yam ntawm cam khwb cia hlau {}}}} Tshwj xeeb}}} muaj tseeb, thaum Ferrosilicon ua tau raws li cov xwm txheej hauv qab no thiab yog siv hauv cam khwb cia hlau ntau lawm, nws yuav raug hu ua ferrosilicon inoculant:
Kev sib xyaw thiab kev ua tau zoo
Cov ntsiab lus silicon siab
Silicon cov ntsiab lus ntawm ferrosilicon inoculants feem ntau yog qhov siab, feem ntau saum toj no 70% (75% ferrosiliconyog ib txwm muaj) {{{. cov ntsiab lus silication muaj peev xwm muab cov khoom sib xyaw kom txaus, thiab kev sib cais dawb ntawm cov kab xis khov kho) .
Tsis tshua muaj cov ncauj lus
Cov ntsiab lus ntawm impurities (xws li sulphur, txhuas, titanium, thiab lwm yam}... Cov kab mob xws li cov hmoov txhuas yuav ua rau cov hws lossis cov kab nrib pleb yog li ntawd, lub impurity index yog qhov qis dua li ntawm derrosilicon .
TSHWJ XEEB LIAJ LOJ BES Txheej Txheem
Qee qhov ferrosilicon inoculants yuav ntxiv me ntsis ntawm cov kab mob me, thiab txhim kho cov khoom ruaj khov, thiab ua kom muaj kev ruaj ntseg thiab ua kom ntev dua ntawm cov inoculation.
Daim Ntawv Thov Qhuab Qhia: Inoculation Kev Kho Mob Ntawm Cam Khwb Xim Hlau
Ferrosilicon yog hu ua "inoculant", thiab nws cov tub ntxhais yog nws lub luag haujlwm hauv kev kho mob inoculation hauv cam khwb cia cov txheej txheem hlau smelting:
Thaum cam khwb cia hlau (xws li hlau cam khwb cia hlau) yog txias thiab khov kho hlau qauv, nws yog ib qho yooj yim ntawm lub zog thiab yooj yim ua kom yooj yim) .
Tom qab ntxiv ib qho me me ntawm ferrosilicon inoculant rau mollation cam khwb cia hlau tuaj yeem ua tau zoo heev hlau, thiab intermities cam khwb cia ntse, lub zog thiab txiav kev ua haujlwm .
Cov tub ntxhais sib txawv los ntawm derrosilicon
Zoo tib yam ferrosilicon:
Mas siv cov deoxidizer, aloying tus neeg sawv cev lossis txo tus neeg sawv cev hauv steelmaking thiab ua rau {{} Piv txwv:
Hauv cov khib nyiab, lub siab axyging ntawm silicon thiab oxygen (tsim cov silicon) yog siv los tshem tawm oxygen los ntawm Molten hlau thiab txo cov hlau thiab txo tus brittleness ntawm cov hlau;
Ntxiv raws li ib qho kev faib tawm rau cov hlau lossis cov hlau pov tseg kom txhim kho lub hardness thiab hnav tsis kam ntawm cov khoom;
Xws li tus neeg sawv cev txo qis hauv Ferrroalloy ntau lawm, nws txo lwm cov hlau oxides (xws li manganese ore thiab chromium.
Inoculant ferrosilicon:
Tshwj xeeb siv rau kev kho inoculation ntawm cam khwb cia hlau (grey cam khwb cia hlau, thiab lwm yam kev ua haujlwm tseem ceeb yog los tswj cov crystallization txheej txheem:
Tom qab ntxiv rau cov cam khwb cia hlau yaj, nws muab ib tug tub ntxhais "rau graphite nucleation ntawm graphite hauv daim ntawv me me thiab tsis muaj flakes);
Inhibit qhov tsim ntawm brittle dawb qauv (xis mas), thiab thaum kawg txhim kho cov tshuab hluav taws xob (kev nruj me me) thiab tshuab cam khwb cia) thiab tshuab cam xim hlau {}}
Cov Tshuaj Sib Nqus Cov Tshuaj Muaj Zog
| Ntsuas | Zoo tib yam ferrosilicon | Inoculant Ferrosilicon |
| Silicon Cov Ntsiab Lus | Feem ntau 45%, 65%, 75%, thiab lwm yam . (faib los ntawm lub hom phiaj) | Feem ntau siab dua, feem ntau yog nyob ib ncig ntawm 75% (txaus Silicon ntsiab yog yuav tsum tau txhawb nucleation) |
| Cov Kws Koom Tes Tswj | Cov leeg xoob (Sulfur, phosphorus, thiab lwm yam . Cia cov ntsiab lus siab dua) | Nrov tsis muaj qhov tsis txaus ntseeg (Sulfur tsawg dua lossis sib npaug ntawm 02%, phosphorus tsawg dua lossis sib npaug ntawm 0.04%, phosphorus tsawg dua lossis sib npaug (xws li pores, nrib pleb) |
| Ib txoj kab lus | Tsis muaj qhov tshwj xeeb xav tau, txawm tias cov tsiaj hauv kev raug tso cai ntau | Cov kab kawm xws li barium, strontium, thiab zirconium, thiab sau ib qho kev sib xyaw ua ke (tsim cov inoculant zoo) los txhim kho qhov tsis muaj txiaj ntsig zoo thiab muaj kev ruaj khov ruaj khov; Cov kev phom sij xws li cov hmoov txhuas thiab titanium yog txwv tsis pub tshaj tus qauv |
Thaum ferrosilicon yog siv nyob rau hauv lub cam khwb cia tus txheej txheem rau lub hom phiaj ntawm cov khoom sib xyaw ua ke), nws yuav raug sau tshwj xeeb cov kab ke), thiab muaj cov kab ke sib xyaw ua ke), thiab cov qauv tshwj xeeb} Nws lub ntsiab yog lub npe ua haujlwm ntawm ferrosilicon hauv ib qho xwm txheej tshwj xeeb muaj kev muaj teeb meem tshwj xeeb, thiab cov tub ntxhais nyob hauv lub embodiment hauv embodiment ntawm "inoculation nyhuv" .
