FeSi 70(Ferro Silicon muaj kwv yees li 70% silicon) yog siv dav hauv kev tsim steel hlau vim nws cov teebmeem metallurgical thiab tshuaj lom neeg. Hauv qab no yog cov ntawv thov tseem ceeb ntawm FeSi70 hauv cov txheej txheem steelmaking:
Ib qho ntawm lub luag haujlwm tseem ceeb ntawm FeSi70 hauv kev ua hlau zoo tib yam yogdeoxidation:
Silicon muaj qhov muaj zog affinity rau oxygen thiab reacts nrog yaj oxygen nyob rau hauv molten hlau los uasilicon monoxide (SiO)thiabsilica (SiO₂), uas ntab nce thiab raug tshem tawm raws li slag.
Los ntawm kev ntxiv FeSi70 thaum tapping lossis hauv lub ladle, steelmakers txo cov pa oxygen, txo qhov porosity thiab txhim kho kev huv.
Kev ua haujlwm zoo deoxidation pab tiv thaiv rov oxidation thaum lub sij hawm casting thiab txo cov non-metallic inclusions.
2. Alloying Element Ntxiv
FeSi70 ua hauj lwm raws li qhov yooj yim ntawmsilicon alloyingnyob rau hauv carbon thiab low-alloy steels:
Silicon nce lub zog thiab hardnesslos ntawm kev daws teeb meem ntxiv dag zog.
Nws txhim khoSib nqus permeabilitythiab hluav taws xob resistivity, ua rau nws pab tau nyob rau hauv hluav taws xob steels thiab transformer core cov ntaub ntawv.
Hauv cov qauv hlau zoo tib yam, me me ntxiv ntawm silicon txhim khoelastic txwvthiab qaug zog kuj.
Nyob rau hauv lub caij nplooj ntoos hlav steels, silicon pab txhawb nqa elastic zog.
3. Inoculation & Graphite Tsim (hauv Cast Irons)
Txawm hais tias muaj ntau dua hauv kev ua haujlwm hauv qhov chaw tsim khoom, thaum kev tsim cov hlau zoo tib yam suav nrog kev tsim cov hlau cam khwb cia:
FeSi70 ua raws li ib qhoua tsis taus panyob rau hauv grey thiab ductile hlau, txhawb nucleation ntawm graphite flakes los yog nodules.
Nws refines tus qauv graphite, txo qhov tob tob thiab txhim kho machinability.
4. Kev hloov kho Slag
Ntxiv FeSi70 hloov kho slag chemistry los ntawm kev nce SiO₂ cov ntsiab lus, uas tuaj yeem pab kho slag fluidity thiab hauv paus:
Kev txhim kho slag fluidity ua kom yooj yim rau kev nqus tau zoo dua thiab tiv thaiv cov ntaub ntawv refractory.
Kho slag muaj pes tsawg leeg pab nyob rau hauv phosphorus thiab sulfur tshem tawm nyob rau hauv thaum ntxov steelmaking theem (tshwj xeeb tshaj yog nyob rau hauv nrog rau lwm yam fluxes).
5. Kev Pabcuam Thaum Muaj Xwm Ceev
Cov tshuaj tiv thaiv exothermic ntawm silicon nrog oxygen tso tawm cua sov:
FeSi70 ntxiv me ntsis nce qhov kub ntawm da dej, pab them nyiaj rau cov cua sov thaum lub sij hawm tapping thiab refining.
Qhov no yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv cov txheej txheem uas yuav tsum tau tswj qhov kub thiab txias ua ntej nruam casting.
6. Kev tswj hwm hom kev suav nrog
Los ntawm kev nyiam ua silicates ntau dua li cov oxides ntawm lwm cov ntsiab lus, FeSi70 cuam tshuam nrog kev sib xyaw ua ke:
Silicate inclusions feem ntau tsis tshua muaj teeb meem rau qhov zoo thiab cov khoom siv kho tshuab piv rau alumina- nplua nuj suav nrog.
Qhov no tuaj yeem yog qhov tseem ceeb rau kev tsim cov hlau huv rau kev sib sib zog nqus nqus lossis vuam daim ntawv thov.
