Txhais thiab siv Ferroalloys
Ferroalloys yog cov alloys uas muaj hlau nrog ib lossis ob peb yam hlau lossis cov hlau tsis yog hlau.
Ferroalloys yog qhov tseem ceeb thiab tseem ceeb raw cov ntaub ntawv rau kev lag luam steel thiab machinery casting kev lag luam, thiab lawv cov kev siv tseem ceeb tuaj yeem ua tiav raws li hauv qab no.
- Siv ua deoxidizer. Deoxygenation yog ntxiv ib co ntsiab lus uas muaj zog affinity rau oxygen dua hlau rau molten hlau, thiab nws oxide yog ib qho yooj yim mus tso tawm los ntawm molten hlau mus rau hauv lub slag, thiaj li hais tias cov pa oxygen cov ntsiab lus nyob rau hauv molten steel yog txo. Cov deoxidizers feem ntau siv hauv steelmaking ntau lawm yog ferrosilicon, ferromanganese, manganese-silicon alloy, calcium-silicon alloy, txhuas, thiab lwm yam.
- Siv ua tus neeg sawv cev alloying. Cov qib steel nrog cov alloying sib txawv thiab cov ntsiab lus muaj cov khoom sib txawv. Cov ntsiab lus ntawm alloying ntsiab nyob rau hauv cov hlau yog kho los ntawm kev sib ntxiv ntawm ferroalloys. Cov khoom siv feem ntau siv yog ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, ferro-molybdenum, ferrotitanium, ferro-niobium, ferroboron, ferronickel, thiab lwm yam. Ferroalloys feem ntau siv los ua cov khoom ntxiv rau cov hlau tsis muaj hlau thiab lwm yam khoom siv raw.
- Siv los ua tus neeg ua kom txo qis. Ferrosilicon tuaj yeem siv los ua tus neeg sawv cev txo qis rau kev tsim cov ferromolybdenum, ferrovanadium thiab lwm yam ferroalloys. Silicon-chromium alloy thiab manganese-silicon alloy tuaj yeem siv los txo cov neeg ua haujlwm rau kev tsim cov pa roj carbon monoxide ferrochrome thiab nruab nrab-tsawg carbon ferromanganese feem.
- Siv ua tus neeg sawv cev nucleating. Ferroalloys kuj tseem siv nyob rau hauv kev lag luam foundry raws li ib tug crystal nucleation inoculant los txhim kho cov txheej txheem casting thiab casting kev ua tau zoo. Nws muaj txiaj ntsig zoo rau kev tsim cov chaw ua qoob loo, ua kom cov nplej zoo dua, thiab txhim kho kev ua haujlwm ntawm castings.
