FERROALLOY

Ferroalloy yog ib qho hlau uas muaj ib los yog ntau dua hlau los yog cov hlau tsis yog hlau fused nrog hlau.Piv txwv li, ferrosilicon yog silicide tsim los ntawm silicon thiab hlau, xws li Fe2Si, Fe5Si3, FeSi, FeSi2, thiab lwm yam. Lawv yog cov khoom tseem ceeb ntawm ferrosilicon.Silicon hauv ferrosilicon feem ntau muaj nyob rau hauv daim ntawv ntawm FeSi thiab FeSi2, tshwj xeeb tshaj yog FeSi yog qhov ruaj khov.Lub melting point ntawm txawv Cheebtsam ntawm ferrosilicon kuj txawv, piv txwv li, 45% ferrosilicon muaj ib tug melting point ntawm 1260 ℃ thiab 75% ferrosilicon muaj ib tug melting point ntawm 1340 ℃.Manganese hlau yog ib qho alloy ntawm manganese thiab hlau, uas kuj muaj me me ntawm lwm yam xws li carbon, silicon, thiab phosphorus.Nyob ntawm nws cov ntsiab lus carbon, manganese hlau tau muab faib ua cov pa roj carbon siab manganese hlau, nruab nrab carbon manganese hlau, thiab cov pa roj carbon tsawg manganese hlau.Manganese hlau alloy nrog cov ntsiab lus silicon txaus yog hu ua silicon manganese alloy.
Ferroalloys tsis yog cov ntaub ntawv hlau uas tuaj yeem siv ncaj qha, tab sis feem ntau yog siv los ua cov khoom siv nruab nrab rau Oxygen scavenger, txo tus neeg sawv cev thiab alloy additives hauv steel ntau lawm thiab kev lag luam casting.
Kev faib tawm ntawm ferroalloys
Nrog rau txoj kev loj hlob ntawm kev tshawb fawb niaj hnub thiab thev naus laus zis, ntau yam kev lag luam tau nce siab ntxiv rau ntau yam thiab kev ua tau zoo ntawm cov hlau, yog li muab cov kev xav tau siab dua ntawm ferroalloys.Muaj ntau hom ferroalloys thiab ntau yam kev faib tawm, uas feem ntau muab faib raws li cov hauv qab no:
(1) Raws li kev faib tawm ntawm cov ntsiab lus tseem ceeb hauv ferroalloys, lawv tuaj yeem muab faib ua cov ferroalloys xws li silicon, manganese, chromium, vanadium, titanium, tungsten, molybdenum, thiab lwm yam.
(2) Raws li cov ntsiab lus carbon hauv ferroalloys, lawv tuaj yeem muab faib ua cov pa roj carbon siab, nruab nrab carbon, qis carbon, micro carbon, ultrafine carbon, thiab lwm yam.
(3) Raws li cov txheej txheem tsim khoom, nws tuaj yeem muab faib ua: blast furnace ferroalloy, hluav taws xob rauv ferroalloy, tawm ntawm lub cub tawg (hlau thermal method) ferroalloy, nqus khoom txo ferroalloy, converter ferroalloy, electrolytic ferroalloy, thiab lwm yam. tshwj xeeb hlau alloys xws li oxide blocks thiab cua sov hlau alloys.
(4) Raws li kev faib tawm ntawm ob los yog ntau dua alloying ntsiab muaj nyob rau hauv ntau yam hlau alloys, lub ntsiab ntau yam xws li silicon aluminium alloy, silicon calcium alloy, silicon manganese aluminium alloy, silicon calcium aluminium alloy, silicon calcium barium alloy, silicon aluminium barium calcium. alloy, thiab lwm yam.
Ntawm peb qhov loj ferroalloy series ntawm silicon, manganese, thiab chromium, silicon hlau, silicon manganese, thiab chromium hlau yog cov ntau yam nrog cov zis ntau tshaj plaws.
