| Cov ntsiab lus impurity (S / P / Al) | S Tsawg dua lossis sib npaug rau 0.03%, P Tsawg dua lossis sib npaug rau 0.04%, Al Tsawg dua lossis sib npaug rau 1.2% | S Tsawg dua lossis sib npaug rau 0.05%, P Tsawg dua lossis sib npaug rau 0.06%, Al Tsawg dua lossis sib npaug rau 1.5% | Tsawg carbon fesi muaj ntau dua purity, ua rau nws haum rau siab -kawg daim ntaub ntawv. |
Nco tseg:Cov pa roj carbon monoxide yog lub luag haujlwm tseem ceeb - carbon qis tiv thaiv embrittlement ntawm steel / castings, kom ntseeg tau cov khoom siv hluav taws xob thiab kev sib txuas; Cov pa roj carbon ntau ua rau Fe₃C-SiC cov theem nyuaj nrog silicon thiab hlau, txhim kho hardness thiab hnav tsis kam, tab sis cov pa roj carbon ntau tuaj yeem ua rau txias brittleness.
Raws li cov ntsiab lus carbon, muaj qhov sib txawv hauv qab no hauv kev siv.
Steelmaking teb
Tsawg carbon ferrosilicon: LC FeSi nrog cov ntsiab lus carbon tsawg dua 1.0% muaj qhov zoo deoxidation thiab alloying cuam tshuam. Nws tuaj yeem txo cov pa oxygen thiab sulfur cov ntsiab lus hauv cov hlau molten, txhim kho qhov zoo ntawm cov hlau molten, txhim khu kev kho cua sov, thiab txhim kho cov dej thiab fluidity ntawm molten steel. Forgeability feem ntau yog siv nyob rau hauv smelting zus tau tej cov carbon steel, alloy structural steel, tshwj xeeb steel thiab hlau alloy, thiab lwm yam.
Siab -carbon ferrosilicon: HC FeSi nrog cov ntsiab lus carbon ntawm 1.0%-2.0% muaj cov nyhuv alloying muaj zog thiab tuaj yeem txhim kho qhov nyuaj thiab lub zog ntawm cov hlau molten. Nws feem ntau yog siv los ntxiv cov alloys rau cov hlau tshwj xeeb, xws li cov hlau tsis muaj steel, cov hlau tsis muaj cua sov, thiab cov hlau tsis muaj zog. Kev them nyiaj rau corroded steel, carbide steel, thiab lwm yam.
Cam khwb cia hlau teb
Tsawg carbon ferrosilicon: Hauv kev tsim cov hlau cam khwb cia hlau, cov pa roj carbon tsawg ferrosilicon tuaj yeem siv los ua ib qho inoculant los txhawb graphitization, txhim kho cov duab thiab kev faib tawm ntawm graphite, ua rau cov hlau cam khwb cia zoo dua qub, thiab txhim kho cov khoom siv ntawm cov hlau cam khwb cia, xws li lub zog, toughness thiab hnav tsis kam. Kev sib deev thiab lwm yam. Nyob rau tib lub sijhawm, qis- carbon ferrosilicon pab txo qis kev nyiam ntawm cov hlau cam khwb cia, txo qhov tshwm sim ntawm qhov tsis xws luag xws li tawg thiab shrinkage qhov hauv castings, thiab txhim kho qhov zoo thiab yield ntawm castings.
Cov pa roj carbon ntau ferrosilicon: Hauv kev tsim cov hlau cam khwb cia nrog lub zog siab thiab siab hardness yuav tsum tau, ntxiv qhov tsim nyog ntawm cov pa roj carbon ferrosilicon tuaj yeem txhim kho qhov hardness thiab lub zog ntawm cov cam khwb cia hlau. Txawm li cas los xij, yuav tsum tau saib xyuas kom tswj tau qhov sib ntxiv kom tsis txhob ua rau cov cam khwb cia hlau nyuaj thiab nkig, uas yuav cuam tshuam rau qhov zoo ntawm cov cam khwb cia hlau. Nws kev ua tau zoo thiab kev siv tau zoo.
Lwm thaj chaw
Tsawg carbon ferrosilicon: Vim nws cov ntsiab lus tsis tshua muaj carbon, nws yog qhov tsim nyog rau kev tsim cov khoom siv hlau lossis cov khoom hlau uas muaj cov ntsiab lus nruj ntawm cov ntsiab lus carbon. Piv txwv li, thaum tsim khoom rau qee cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam, kev siv qis -carbon ferrosilicon tuaj yeem ua kom zoo dua thiab ua haujlwm zoo ntawm cov khoom thiab tsis txhob cuam tshuam cov hluav taws xob conductivity, thermal conductivity thiab lwm yam khoom ntawm lub cev ntawm cov khoom vim cov ntsiab lus carbon ntau dhau.
