Calcium-silicon cored hlauyog ib qho tseem ceeb ntawm cov khoom siv kho kom zoo nyob rau hauv niaj hnub steelmaking thiab foundry industries. Cias muab, nws tuaj yeem piav qhia tias yog "tshwj xeeb tsim alloy hlau": ib txheej steel strip nruj nreem qhwv ib ncig ntawm calcium -silicon alloy hmoov sab hauv. Siv cov khoom siv tshwj xeeb hlau pub, nws tuaj yeem raug txhaj rau hauv cov hlau molten, yog li txhim kho cov hlau zoo. Nrog nws txoj kev "steel strip-wrapped alloy hmoov" tsim, nws hais txog ntau yam teeb meem ntawm cov txheej txheem deoxidation thiab desulfurization, ua rau nws yog ib qho tseem ceeb hauv kev tsim cov hlau zoo - zoo.
Yam khoom thiab Core Advantages
Cov qauv khoom: Calcium-silicon alloy hmoov (feem ntau muaj 28-30% Ca thiab 55-60% Si) yog encapsulated nyob rau hauv ib tug tsawg-carbon steel sawb los tsim cov xov hlau nrog ib txoj kab uas hla ntawm 10-13mm.
Core Zoo:
| Qhov zoo | Kev ua haujlwm tshwj xeeb |
|---|---|
| Surge hauv Yield | Tus nqi rov qab ntawm calcium nce los ntawm 1-3% hauv cov tsoos bulk ntxiv rau 10-30% nrog cored hlau pub, thiab tuaj yeem ncav cuag 35-40% nrog kev tswj kev pub mis. |
| Precise Component Control | Ua kom muaj kev tswj xyuas qhov tseeb ntawm qhov sib ntxiv (kev ua yuam kev < 5%), tso cai rau kev nplua - kho cov hlau molten muaj pes tsawg leeg, tshwj xeeb tshaj yog tsim nyog rau kev ntxiv cov kab xws li B thiab Ti. |
| Mob me thiab tswj tau qhov tshwm sim | Tsis txhob ua nruj ua tsiv ntawm cov hlau molten, txo cov oxidation theem nrab, thiab txhim kho kev nyab xeeb ntawm kev ua haujlwm. |
| Txo Tus Nqi Tag Nrho | Alloy noj yog txo los ntawm 30-50%, slag ntim yog txo los ntawm 15-20%, slag skimming zaus yog txo, thiab cov khoom pov tseg cov nqi kho mob yog txiav los ntawm 10-15%. |
| Automation Compatibility | Cov cuab yeej yooj yim, me me hneev taw, thiab tuaj yeem ua ke rau hauv cov txheej txheem steelmaking automation uas twb muaj lawm. |
II. Core Functions: "Triple Purification" ntawm Molten Steel
1. Muaj zog Deoxidation
Tsim tej yam kev mob rau refining tom ntej thiab txhim kho steel huv si.
2. High-Kev Ua Haujlwm Desulfurization
Calcium muaj kev sib raug zoo rau leej faj, tsim CaS (lub ntsiab lus melting ntawm 2450 degree) nrog desulfurization efficiency ntawm 40-50%
Qhov tseem ceeb txo qhov kub brittleness ntawm steel thiab txhim khu nws cov kev ua tau zoo
3. suav nrog "Kev hloov pauv"
Nws txoj haujlwm tseem ceeb tshaj plaws: hloov cov teeb meem angular Al₂O₃ suav nrog rau hauv cov pob zeb calcium aluminate
Qhov "morphological kiv puag ncig" no txhim kho steel isotropy, ua rau qaug zog ntau dua 30%, thiab txo qis nruam casting nozzle clogging ntau dua 50%.
Zuag qhia tag nrho, calcium-silicon cored hlau yog siab- cov khoom siv hlau ua tau zoo uas tuaj yeem txhim kho steel zoo thiab txo cov nqi tsim khoom. Nws yog tshwj xeeb tshaj yog haum rau steelmaking thiab casting scenarios uas muaj cov kev xav tau siab rau steel purity, toughness, thiab kev ua tau zoo.
Thaum xaiv thiab siv nws, koj tuaj yeem xa mus rau cov lus qhia hauv qab no:
Qhia kom meej: Yog tias muaj cov kev xav tau nruj me ntsis rau cov ntsiab lus hydrogen hauv cov hlau, tshwj xeeb yuav tsum tau them nyiaj rau cov khoom noo noo- pov thawj ntim lossis xav txog kev siv cov calcium uas txhim kho- silicon cored hlau nrog cov dej noo{2}} cov qauv tiv thaiv.
Qhia kom meej: Yog tias muaj cov kev xav tau nruj me ntsis rau cov ntsiab lus hydrogen hauv cov hlau, tshwj xeeb yuav tsum tau them nyiaj rau cov khoom noo noo- pov thawj ntim lossis xav txog kev siv cov calcium uas txhim kho- silicon cored hlau nrog cov dej noo{2}} cov qauv tiv thaiv.
Xaiv ib tus neeg muab kev ntseeg siab:Nrog ntau tus neeg muag khoom nyob rau hauv kev ua lag luam (xws li Anyang Jintong Metallurgical Refractory Co., Ltd.), xaiv cov khoom uas muaj cov khoom ruaj khov thiab txhim khu kev qha zoo yog qhov tseem ceeb.
