Ferro Calcium Silicon Hmoov

FERRO CCACIACE Silicon Hmoov yog aComposite Ferrro AlloyCov khoom siv tseem ceeb hauv cov liaj teb ntawm metallurgy thiab casting. Hlau (FE) yog lub zog matrix yog lub zog yooj yim thiab ruaj khov rau cov alloy thiab yog ib qho ntawm cov khoom sib xyaw ntawm cov alloy. Silicon muaj lub zog deseoxidizing muaj peev xwm. Thaum lub sij hawm steelmaking thiab cam khwb cia, nws tuaj yeem sib txuas nrog oxygen los ua cov lus zais pa hauv molten hlau thiab txhim kho lub purity ntawm cov hlau. Nyob rau tib lub sijhawm, silicon kuj tseem tuaj yeem txhim kho lub zog, hardness thiab kub ua luam ntawm cov hlau thiab cov hlau cam khwb cia. Calcium tseem suav rau qee qhov kev faib ua feem nyob rau hauv cov calcium hlau Silicon hmoov. Cov tshuaj calcium tuaj yeem ua tau zoo desulfurize, txo cov lus faj sulfur hauv cov qauv hlau thiab muab cov hluav taws xob tsis zoo ntawm cov pob zeb hlau, xws li kub brittleness. Tsis tas li ntawd, calcium tseem tuaj yeem txhim kho cov fluidity ntawm cov hlau thiab cam khwb cia hlau, refine nplej, thiab txhim kho cov khoom zoo thiab kev ua tau zoo ntawm cov cuab yeej.

Lwm cov ntsiab lus kuj tseem muaj ib qho me me ntawm txhuas (al), carbon (c), phosphorus (p), leej faj (cov leeg. Txawm hais tias cov ntsiab lus ntawm cov ntsiab me me no yog me me, lawv kuj yuav muaj qee yam cuam tshuam rau cov calcium hlau Silicoron Hmoov, thiab lawv cov ntsiab lus xav tau nruj me nyuam thaum lub sijhawm tsim khoom. Piv txwv li, txhuas kuj tseem muaj cov nyhuv desexidizing rau qee yam, tab sis ntau dhau txhuas yuav cuam tshuam rau cov hlau tawv; Cov ntsiab lus tsis txaus siab xws li cov pa roj carbon, phosphorus, thiab leej faj yuav txo cov kev ua tau zoo ntawm cov hlau, thiab lawv cov ntsiab lus feem ntau yuav tsum tau ua kom tsawg li sai tau.

Cov Khoom Siv Khoom Raw:

Silica (sio₂ cov ntsiab lus ntau dua los yog sib npaug ntawm 98%), limestone (khaws cov roj ntsha ntau dua lossis sib npaug nrog 85%) yog siv los ua cov khoom siv raw. Lawv sib xyaw thiab tsoo rau qhov loj ntawm 5-20 hli raws li cov piv txwv tsim nyog.

High - kub smelting:

Cov khoom siv raw yog pub rau hauv lub submerged arc rauv (tseem hu ua lub cub hluav taws arc). Ntawm qhov kub ntawm 1800-2000 degree, ib qho kev hloov pauv ntawm cov roj carbon monloy (cov tshuaj tiv thaiv CaOy (cov tshuaj tiv thaiv Ca

Crushing thiab pulverizing:

Lub txiaj ntsig siliconcalcium alloy ingots yog txias, tsoo hauv lub puab tsaig crusher thiab pob zeb zeb, thaum kawg tshuaj ntsuam kom tswj tau cov hmoov txawv ntawm sib txawv.

Deoxidizer

Hauv cov txheej txheem statmaking,Calcium siliconHmoov yog ib qho zoodeoxidizerCov. Cov nyhuv synergistic ntawm silicon thiab calcium tuaj yeem txo cov kua roj oxygen hauv cov hlau, thiab txhim kho lub purity thiab zoo ntawm cov hlau. Piv nrog ib deoxidization ib leeg, calcium hlau Silicon hmoov muaj qhov yuav tsum muaj cov kev xav tau ntawm nruj me nyuam yaus rau kev coj dawb huv ntawm Molten Steel.

Desulfurizer

Cov tshuaj calcium tuaj yeem hnov ​​cov sulfur thaum lub sijhawm steelmaking kom tsim cov calcium sulfide thiab sau lub ntsej muag slag, yog li txo cov ntsiab lus sulfur hauv cov hlau. Rau qee cov steel hom nrog nruj me ntsis ntawm cov duab kab mob sulphur, xws li cov roj carbium zoo yog qhov tseem ceeb tshaj plaws thiab cov khoom siv tshuab ua haujlwm zoo ntawm cov hlau.

Alloying Tus Neeg Sawv Cev

Silicon, calcium thiab lwm yam hauv fecasi hmoov tuaj yeem muab ntxiv rau cov hlau liAlloying NtsiabTxhawm rau kho cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau thiab txhim kho lub zog, hardness, muaj zog thiab kub ua hauj ntawm cov hlau. Piv txwv li, thaum tsim kev lag luam siab siab- Lub zog alloyoL hlau, ntxiv Casi hmoov nyob rau hauv cov txheej txheem tsim nyog tuaj yeem ua kom zoo rau nws txoj kev ua tau zoo.

Inoculant

Hauv cov txheej txheem casting, Ferro silicon calcium hmoov tuaj yeem siv ua ib qho inoculant. Nws tuaj yeem txhawb nqa cov crystallization thiab kev loj hlob ntawm cov hlau pov tseg, tshuaj kho cov pob zeb, thiab txhim kho cov khoom siv me me ntawm cov hlau cam khwb cia ntawm cam khwb cia hlau. Tshwj xeeb tshaj yog nyob rau hauv kev tsim cov grey cam khwb cia hlau thiab ductility cov kab mob ntawm cov nrum, thiab txhim kho kom zoo thiab ua kom zoo thiab tawm ntawm cov chaw castings.

Nodularizer auxiliary Tus Neeg Sawv Cev

Hauv kev tsim cov hlau uas muaj ntau lawm, cov ferro calcium silicon hmoov tuaj yeem siv ua ib qho kev pab ntxiv rau spheroidizer. Thaum siv nyob rau hauv kev sib txuas nrog tus neeg sawv cev sib txawv, nws pab ruaj khov cov nyhuv ntaub, thiab txuas ntxiv txhim kho cov hlau ua kom tau raws li cov khoom siv ntau ntxiv.
