CaSi (Calcium Silicon) cored hlauyog ib qho tseem ceeb nplua - kho metallurgical khoom nyob rau hauv niaj hnub theem nrab steelmaking. Nws muab cov calcium thiab silicon supplementation, hloov kho oxide thiab sulfide inclusions, txhim kho steel castability, thiab txhim kho cov neeg kho tshuab kawg. Tsis zoo li cov pa roj carbon monoxide, cored hlau nta ruaj khov noj, siab lub ntsiab lus rov qab, thiab tsawg kub poob. Txawm li cas los xij, tsis sib haum CaSi hlau cov lus qhia tshwj xeeb rau cov qib steel sib txawv yuav ua rau muaj kev tswj xyuas tsis ruaj khov, tsis zoo ntawm qhov chaw, thiab cov nqi ntau lawm.
Core Functions ntawm Calcium Silicon Cored Hlau hauv Steelmaking
Ua ntej xaiv, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab lus tseem ceeb ntawm CaSi CW, uas txiav txim siab koj cov kev xav tau tshwj xeeb:
- Kev hloov pauv suav nrog:Converts nyuaj, tsis xwm yeem alumina inclusions rau hauv mos, kheej kheej calcium aluminate inclusions, zoo txo nozzle clogging thaum nruam casting.
- Desulfurization & Deoxidation:Tshem tawm cov pa oxygen thiab leej faj nyob hauv cov hlau molten, txhim kho steel purity thiab homogeneity.
- Mechanical Property Optimization:Refines cov qauv nplej, txhim kho steel toughness, qaug zog tiv thaiv, thiab cuam tshuam kev ua tau zoo, tshwj xeeb tshaj yog rau qis- alloy thiab siab - lub zog steel.
- Kev ruaj khov Alloy rov qab:Kaw hlau pub mis txo lub caij volatilization, kom ntseeg tau tias Ca thiab Si cov ntsiab lus batch los ntawm batch.
Kev xaiv tseem ceeb rau CaSi Cored Hlau
Cov kws tshaj lij steel mills txiav txim cov hlau tsim nyog raws li peb qhov tseem ceeb, uas siv rau txhua qhov kev tsim khoom hauv qib steel:
Chemical Composition Ratio
Cov qib kev lag luam feem ntau suav nrog cov qauv Ca28Si60, Ca30Si60, thiab qib siab -calcium customized qib. Cov ntsiab lus calcium ntau dua muaj kev hloov kho ntxiv thiab desulfurization muaj zog, thaum cov ntsiab lus silicon ua kom ruaj khov deoxidation efficiency.
Hlau Diameter & Filling Rate
Qhov ntau thiab tsawg yog 9mm thiab 13mm. Cov hlau zoo (9mm) haum zoo meej -tu thiab qis- noj tshuaj noj; tuab hlau (13mm) haum rau cov ladles loj thiab siab - tawm cov kab nruam nruam nrog ntau dua ib -meter filling ntim.
Sheath Material & Sealing Zoo
Tsawg- carbon steel sheath nrog nruj vuam txwv tsis pub cov hmoov to thiab noo noo nqus, ua kom ruaj khov ceev ceev thiab zoo sib xws metallurgical cuam tshuam thoob plaws hauv kev tsim khoom.
Qib-Tshwj xeeb CaSi Cored Wire Selection Guide
Qhov no yog qhov siv tau tshaj plaws rau cov neeg ua haujlwm txawv teb chaws. Ntau hom hlau yuav tsum tau tsom CaSi hlau specifications kom sib npaug zoo stability thiab ntau lawm nqi.
Ordinary Carbon Steel & Siv Hlau
Pom zoo Qib: Ca28Si60, 13mm txheem hlau
Rau Q235, Q355 thiab cov qauv hlau zoo sib xws, cov pa deoxidation thiab kev tswj hwm suav nrog txaus. Standard Ca28Si60 xaim muab kev ruaj khov desulfurization thiab qis -tus nqi suav nrog kev hloov kho. Nws ua tau zoo txo qhov tsis xws luag thiab ua tau raws li qhov xav tau ntau lawm nrog kev ua haujlwm zoo heev.
Tsawg-Alloy Siab-Strength Steel & Pipeline Steel
Qib pom zoo: Ca30Si60 siab -calcium hlau
Pipeline steel thiab siab -lub zog cov qauv hlau xav tau ultra- huv si molten steel thiab cov qauv sab hauv. High-calcium CaSi hlau hloov kho cov alumina suav nrog, tsis txhob muaj cov nozzle clogging hauv siab- nrawm nruam nruam, thiab txhim kho steel toughness thiab weldability.
Caij nplooj ntoos hlav Steel & Tool Steel
Qib pom zoo: Tsawg- impurity Ca30Si60 hlau
Lub caij nplooj ntoos hlav steel thiab cov cuab yeej hlau yog qhov tsis tshua muaj siab rau kev suav nrog thiab cov khoom seem seem. Tsawg-sulfur, qis-phosphorus siab- purity CaSi cored hlau yog yuav tsum tau kom tsis txhob nkig inclusions, stabilize elastic txwv thiab hardness sib xws, thiab ua kom tiav cov khoom qaug zog lub neej.
Hluav taws xob hlau & Ultra-Low Carbon Steel
Qib pom zoo: Custom high-Ca low-Si hlau
Ultra- cov pa roj carbon tsawg thiab cov hlau hluav taws xob muaj kev txwv nruj ntawm silicon residuals. Txais siab -calcium thiab low- silicon customized CaSi hlau kom ua tau raws li kev hloov kho calcium uas tsis muaj ntau tshaj li cov hlau silicon specification, xyuas kom cov hlau nplaum conductivity thiab cov khoom purity.
Iron Ductile & High -Qib Castings
Pom zoo Qib: Standard Ca28Si60, 9mm zoo hlau
Zoo- loj cored hlau ua kom cov hlau molten hlau nucleation, refines graphite qauv, txhim kho casting fluidity, thiab zoo tshem tawm shrinkage porosity thiab txias kaw tsis xws luag rau precision castings.
Kev tshaj lij kev siv & cov lus qhia yuav khoom
- Sib tw pub ceev:Tswj kev ceev ceev ntawm 15-25 m / min raws li lub peev xwm ladle kom paub tseeb tias calcium melts tag nrho thiab tsis txhob poob poob.
- Strict Impurity Control:High-kawg steel ntau lawm yuav tsum tau qis S/P CaSi hlau hlau los tiv thaiv cov pa phem thib ob ntawm cov hlau molten.
- Batch Consistency Check:Tshawb xyuas CoA cov ntawv ceeb toom rau txhua pawg kom ruaj khov Ca/Si piv thiab ntim ntim.
- Qhuav Cia:Khaws cored hlau kaw thiab qhuav kom tsis txhob ya raws -induced feeding jamming thiab molten steel splashing.
Xaiv qhov raug Calcium Silicon CW rau cov qib steel sib txawv yog tus yuam sij rau stabilizing steel purity, txhim kho kev ua tau zoo, thiab ua kom zoo dua cov nqi tsim khoom. Ordinary carbon steel adapts tus qauv Ca28Si60 rau cov nqi ua haujlwm; siab-lub zog thiab cov kav dej hlau yuav tsum muaj siab-calcium Ca30Si60 rau kev hloov kho sib sib zog nqus; ultra- cov pa roj carbon tsawg thiab hluav taws xob hlau xav tau kev hloov kho qis- cov lus qhia tshwj xeeb. Los ntawm kev sib piv cov hlau muaj pes tsawg leeg, txoj kab uas hla thiab kev pub mis rau cov qib steel tshwj xeeb, steel mills tuaj yeem ua tiav cov teebmeem metallurgical ruaj khov, txo tus nqi tsis zoo, thiab ua kom muaj txiaj ntsig ntau lawm.
