Ferro Calcium Cored Wire yog cov khoom siv sib xyaw ua ke uas ua los ntawm nruj nreem kaw kom zoocalcium ferro alloy hmoovnyob rau hauv ib tug nruam steel sawb. Nws yog precisely txhaj rau hauv lub molten hlau nyob rau hauv lub ladle ntawm ib tug tswj ceev thiab qhov tob siv ib tug tshwj xeeb hlau feeder. Qhov kev tsim no daws cov teeb meem ntawm qhov tsis sib haum xeeb, qis- ntom ntom, thiab nyuaj- rau- ntxiv calcium hlau, ua rau nws yog ib qho tseem ceeb rau kev ua tau zoo "calcium kho" hauv ladle refining thiab tseem ceeb heev rau kev ua tau zoo - purity, siab - steel kev ua tau zoo.

Vuam Hlau Hlau, Cold Heading Steel	Txhim kho kev suav nrog morphology, tiv thaiv tensile puas	Txhim kho hlau kos duab kev ua tau zoo thiab tawm los.
Aluminium Deoxidized tua hlau	Tiv thaiv nozzle thaiv, txhim kho castability	Xyuas kom du nruam casting thiab ua kom ntau lawm efficiency.

Khoom Specifications thiab Daim Ntawv Qhia Kev Siv

Qhov project	Cov lus qhia thiab cov lus pom zoo
Hlau Dia	Common Specifications: 9mm, 10mm, 13mm. Kev xaiv yuav tsum yog raws li tus qauv pub hlau thiab lub peev xwm ladle kom ntseeg tau tias qhov kev pub mis tob mus txog qhov pom kev pom zoo ntawm cov hlau molten.
Core Composition	Calcium Cov ntsiab lus (Ca): Feem ntau 28% -32%,nrog cov seem feem ntau muaj hlau (Fe) thiab me me ntawm txhuas (Al) thiab silicon (Si). Cov ntsiab lus calcium siab ua kom cov txiaj ntsig kev kho mob zoo dua thiab txo cov xaim ntau npaum li cas.
Filling Ratio	Qhov no yog hais txog qhov feem pua ntawm cov hmoov hnyav rau tag nrho qhov hnyav ntawm cov hlau, feem ntau 30% -40%. Tus nqi ruaj khov yog qhov tseem ceeb rau kev ua kom muaj cov calcium uas tsis sib xws hauv ib lub meter ntawm cov hlau.
Npog Txheej	Feem ntau qis- cov pa roj carbon steel sawb nrog cov tuab tuab thiab muaj zog welds kom tsis txhob tawg lossis hmoov to thaum pub mis.
Spool Ntim	Txheem spools (piv txwv li, 500-1500 meters / spool), ruaj ntseg ntim kom tsis txhob xaim tangling.

Cov khoomKev siv thiab ntim khoom

1: Purifying Molten Steel thiab Deep Deoxidation thiab Desulfurization

Deep Deoxidation:

Calcium (Ca) muaj kev sib raug zoo rau cov pa oxygen (O), ntxiv txo cov pa oxygen hauv cov hlau los ntawm aluminium deoxidation, tsim kom tsawg - melting -point calcium aluminate complex inclusions.

High -Efficiency Desulfurization:

Calcium reacts nrog sulfur (S) nyob rau hauv steel los ua kheej kheej los yog dot -zoo li calcium sulfide (CaS), txo cov sulfur cov ntsiab lus thiab cov teeb meem ntawm manganese sulfide (MnS), tiv thaiv "sulfide streaks" thaum lub sij hawm steel dov, thiab txhim kho isotropy.

2: Tsis yog -Metallic Inclusion Morphology Control (Core Value)

Qhov no yog lub hom phiaj tseem ceeb ntawm kev kho calcium. Tsis kho Al₂O₃ (alumina) suav nrog yog cov saw hlau -zoo li los yog pawg, nrog cov hardness siab thiab melting point, ua rau lub neej qaug zog, toughness, thiab kev ua haujlwm ntawm steel (xws li, ua rau tensile tawg).

Cov nyhuv "Modification":

Calcium tuaj yeem hloov kho siab - melting- taw tes khoom Al₂O₃ suav nrog rau hauv qis- melting-point (~1600 degree) kua calcium aluminates (xws li 12CaO·7Al₂O₃).

Cov txiaj ntsig:

Cov kua dej suav nrog feem ntau yuav sib tsoo, sib sau ua ke, thiab ntab mus rau txheej slag kom tshem tawm thaum lub sij hawm molten steel casting. Txawm tias qhov me me ntawm cov seem ntxiv tau muab faib rau hauv cov duab kheej kheej me me, txo lawv cov teeb meem rau cov khoom hlau. Qhov no yog hu ua "nrog kev kho mob spheroidization."

3: Txhim kho steel castability thiab tiv thaiv nozzle blockage

Hauv kev nruam nruam, tsis kho Al₂O₃ suav nrog yooj yim tso rau ntawm phab ntsa sab hauv ntawm lub nozzle, ua rau lub nozzle nqaim lossis txawm tias thaiv, ua rau muaj kev cuam tshuam ntau lawm.

Calcium kev kho mob khaws cov kev suav nrog hauv cov kua hauv lub xeev, ua rau lawv tsis tshua ua raws li cov phab ntsa nozzle, yog li ua kom muaj kev sib tw nruam nruam, nce tus naj npawb ntawm cov cua sov sib law liag, thiab txo qhov kev sib tsoo ntau lawm.

4: Microalloying thiab Performance Enhancement

Calcium yog cov khoom noj muaj zog, pab txhim kho qhov qis -kub toughness thiab weldability ntawm hlau.

Hauv siab-cov khoom tshwj xeeb zoo, xws li cov kabmob steel, iav steel, lub caij nplooj ntoos hlav steel, thiab hnyav- lub luag haujlwm log steel, kev kho calcium yog txheej txheem txheej txheem los xyuas kom muaj zog qaug zog thiab ua haujlwm ntev.
