Calcium silicon alloy (CaSi)yog ib lub siab -kev ua tau zoo sib xyaw alloy uas ua ke nrog lub zog deoxidizing lub caij silicon (Si) nrog lub zog desulfurizing thiab suav nrog hloov pauv cov calcium (Ca). Muab piv rau kev sivferrosiliconlos yog ntshiab calcium ib leeg, silicon calcium alloy ua tiav "ib tus neeg sawv cev, ntau lub zog." Nyob rau hauv lub ladle refining theem ntawm steelmaking, tshwj xeeb tshaj yog thaum lub sij hawm kho calcium nyob rau hauv lub ladle (LF rauv, RH rauv), nws muaj peev xwm ua tau ib txhij thiab ua kom tiav cov haujlwm tseem ceeb hauv qab no:

Deep Deoxidation thiab Desulfurization:Silicon thiab calcium ua hauj lwm synergistically kom txo cov pa oxygen thiab sulfur cov ntsiab lus nyob rau hauv molten hlau.

Inclusion morphology tswj (hloov kho):Qhov no yog nws txoj haujlwm tseem ceeb tshaj plaws. Calcium tuaj yeem hloov kho qhov teeb meem, siab - melting- taw tes khoom Al₂O₃ (alumina) suav nrog hauv cov hlau molten rau hauv qis- melting-point kua calcium aluminates (xws li 12CaO·7Al₂O₃), ua rau lawv yooj yim rau ntab thiab tshem tawm.

Txhim kho steel fluidity:Ntshiab molten steel thiab kua inclusions zoo tiv thaiv nruam casting nozzle blockage, kom ntseeg tau du ntau lawm.

Yog li ntawd, casi alloys yog ib qho tseem ceeb ntxiv rau hauv kev lag luam steel niaj hnub no, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov qib siab -tus nqi- ntxiv, siab -kev ua tau zoo huv si thiab cov hlau tshwj xeeb.

CaSi Alloy Composition thiab cov khoom

1. High-kawg Pipeline Steel Production

Core Function:Tswj sulfide morphology thiab tiv thaiv hydrogen -induced cracking (HIC). Pipeline steels (xws li X60, X70, X80 thiab saum toj no) yuav tsum tau ua haujlwm nyob rau hauv siab -siab, corrosive ib puag ncig rau ncua sij hawm. Calcium nyob rau hauv CaSi tuaj yeem hloov kho elongated MnS (manganese sulfide) suav nrog rau hauv spherical los yog dot-zoo li (Ca, Mn)S, zoo heev txo lawv rhiab heev rau tawg tawm thiab ua kom cov kav dej nyab xeeb thaum thauj cov kua qaub tawm.

Qib Xaiv:Cov qib nrog cov ntsiab lus nruab nrab mus rau siab calcium, xws li Ca28Si60 lossis Ca31Si60, feem ntau raug xaiv los ua kom muaj zog calcium txaus.

2. High-Cov Kabmob Cov Hlau, Cov Hlau Hlau, thiab Lub Caij Nplooj Hlav Hlau Smelting

Core Function:Purifying molten steel thiab txhim kho lub neej qaug zog. Cov kabmob, lub zog, thiab lwm yam khoom siv tau raug siab - lub voj voog hloov kev ntxhov siab, thiab cov oxide suav nrog hauv cov hlau yog lub hauv paus ntsiab lus ntawm kev qaug zog tawg. Kev kho CaSi tuaj yeem ua kom zoo, spheroidize, thiab disperse residual oxide inclusions, yog li txhim kho cov khoom sib cuag qaug zog thiab dov lub neej qaug zog.

Cov ntsiab lus tseem ceeb ntawm txheej txheem:Hauv hom high-carbon steel lossis nruab nrab- siab carbon alloy steel, cov calcium ntxiv yuav tsum raug tswj kom tsis txhob muaj qhov loj ntawm -calcium aluminate inclusions.

3. Kev kho Calcium ntawm Aluminium-Tua Hlau (xws li, daim ntawv tsheb, sib sib zog nqus- kos duab hlau)

FAQ

Q: Dab tsi yog qhov txawv ntawm calcium silicon alloy thiabcalcium silicon alloy cored hlau? Kuv yuav xaiv li cas?

A: Ob leeg muaj tib lub hauv paus ntsiab lus, tab sis txawv ntawm daim ntawv thiab daim ntawv thov. Calcium-silicon alloy blocks/granules feem ntau yog siv los ntxiv rau cov slag nto ntawm steel ladles lossis los ntawm cov khoom siv tshwj xeeb, tsim nyog rau cov ntawv thov uas xav tau kev kho calcium siab. Calcium-silicon alloy cored hlau, ntawm qhov tod tes, muaj cov hmoov hlau alloy encased nyob rau hauv ib tug hlau sawb thiab precisely txhaj rau hauv qhov tob ntawm cov hlau molten siv ib tug hlau feeder. Qhov no ua rau cov calcium rov qab siab dua thiab ruaj khov dua, tsim nyog rau qib siab -kawg steel (xws li ultra-cov pa roj carbon tsawg thiab cov hlau hluav taws xob) nrog cov calcium uas tsis tshua muaj siab rau kev kho mob precision. AON Metals muaj ob yam khoom thiab tuaj yeem pom zoo rau kev daws teeb meem zoo tshaj plaws rau cov neeg siv khoom.

Q: Yuav ua li cas yog "calcium rov qab tus nqi" ntawm kev kho calcium suav? Yam dab tsi cuam tshuam rau nws?

A: Calcium rov qab tus nqi=(Tus nqi ntawm calcium absorbed los ntawm molten steel / Tag nrho cov nyiaj calcium ntxiv) × 100%. Qhov no yog qhov qhia txog txheej txheem tseem ceeb, feem ntau yog li ntawm 15% txog 35% raws li kev paub dhau los. Nws yog feem ntau cuam tshuam los ntawm molten steel kub, [O] thiab [S] cov ntsiab lus, ntxiv txoj kev (blocks / hlau pub), qhov tob ntawm qhov sib ntxiv, thiab steel muaj pes tsawg leeg. Peb pab pawg kws tshaj lij tuaj yeem muab cov txheej txheem txheej txheem kev pom zoo.

Q: Kuv yuav txiav txim siab npaum li cas ntawm cov nyiaj casi alloy ntxiv rau kuv qib steel?

A: Cov nyiaj ntxiv (kg / ton ntawm steel) nyob ntawm qhov tseem ceeb ntawm qib steel qib cov ntsiab lus calcium uas yuav tsum tau muaj, qhov hnyav ntawm cov hlau molten, cov ntsiab lus calcium ntawm qib CaSi, thiab cov calcium uas xav tau. Ib qho yooj yim xam cov mis yog: Ntxiv nyiaj ≈ (Steel yuag × Target calcium ntsiab lus) / (Calcium ntsiab lus nyob rau hauv CaSi × Calcium rov qab tus nqi). Cov me me -batch industrial sim tau pom zoo rau kev siv thawj zaug los txiav txim siab cov txheej txheem tsis zoo.
