SiAlBaCa Alloy

Silicon aluminium barium calcium (sialbaca) alloy yog cov khoom sib xyaw uas muaj ntau yam xws li silicon (Si), aluminium (Al), barium (Ba), thiab calcium (Ca). Nws yog lub siab -kev ua tau zoo deoxidizer thiab desulfurizer ntawm barium-raws li alloys. Cov khoom no muaj ib tug silvery - grey metallic luster thiab feem ntau yog muab nyob rau hauv daim ntawv thaiv, granular, los yog hmoov. Raws li cov khoom siv tseem ceeb hauv kev lag luam hlau niaj hnub smelting thiab casting, SiAlBaCa Alloy, los ntawm kev sib koom ua ke ntawm nws ntau lub ntsiab lus, tuaj yeem txhim kho cov purity ntawm molten steel thiab txhim kho cov khoom siv ntawm castings, ua rau nws zoo tagnrho hloov kho los ntawm ib txwm deoxidizers.

Cov txheej txheem ntau lawm

Nco tseg:Cov ntaub ntawv nyob rau hauv lub rooj yog qhov tseem ceeb; cov txheej txheem tshwj xeeb tuaj yeem kho raws li cov neeg siv khoom xav tau.

1. Deoxidation Mechanism

Silicon, txhuas, thiab calcium yog tag nrho cov muaj zog deoxidizing ntsiab. Lawv tuaj yeem hnov ​​​​mob nrog cov pa oxygen hauv cov hlau molten los tsim cov oxides ruaj khov, yog li txo qis tag nrho cov pa oxygen hauv cov hlau molten:

 Silicon (Si):Ib qho yooj yim deoxidizing keeb, tsim SiO₂

 Aluminium (Al):Lub zog deoxidizer, tsim Al₂O₃, nrog kev ua haujlwm siab deoxidation

 Calcium (Ca):Cov khoom muaj zog deoxidizing, tsim CaO

 Barium (Basic):Txawm hais tias nws tus kheej deoxidizing muaj peev xwm kuj tsis muaj zog, nws tuaj yeem txo qhov vapor siab ntawm calcium, ua rau kom cov dej solubility thiab siv tus nqi ntawm calcium hauv molten steel, thiab indirectly txhim khu cov nyhuv deoxidation.

Cov kev tshawb fawb tau pom tias thaum siv barium - muaj cov alloys (xws li SiAlBaCa) ua deoxidizers, tag nrho cov pa oxygen hauv cov hlau tuaj yeem raug txo kom qis qis, thiab cov khoom deoxidation tau yooj yim ntab thiab tshem tawm.

2. Desulfurization Mechanism

Calcium muaj kev sib raug zoo heev rau leej faj thiab tuaj yeem hnov ​​​​mob nrog sulfur hauv molten steel los tsim CaS, yog li tshem tawm cov sulfur zoo. Lub xub ntiag ntawm txhuas ntxiv txhim kho cov nyhuv desulfurization, tsim cov txhuas-calcium dual composite desulfurization mechanism.

3. Inclusion Modification Mechanism

Ib txwm deoxidation ua rau Al₂O₃ suav nrog uas yog nkig thiab tsis sib xws, cuam tshuam rau kev ua haujlwm qaug zog thiab ua haujlwm ntawm cov hlau. Tom qab deoxidation ntawm silicon-aluminium-barium-calcium alloys, complex oxides uas muaj calcium, barium, silicon, thiab txhuas yog tsim. Cov kev suav nrog no muaj qhov zoo hauv qab no:

 Tsawg ceev:Yooj yim floats thiab tshem tawm los ntawm molten steel.

 Txhim kho morphology:Hloov mus rau hauv spherical, uniformly faib zoo inclusions.

 Nce toughness:Tseem ceeb txhim kho qhov cuam tshuam toughness thiab machinability ntawm cov hlau.

1. Hlau thiab hlau Smelting kev lag luam

Silicon aluminium barium calcium alloy yog cov khoom siv tau zoo heev hauv cov txheej txheem steelmaking, haum rau deoxidation hauv ntau txoj kev steelmaking, tshwj xeeb tshaj yog rau converter steelmaking.

Application Scenario:

Core Advantages:

 Strong Deoxidation thiab Desulfurization: Ib txhij ua tiav deoxidation sib sib zog nqus thiab muaj txiaj ntsig desulfurization.
 Txhim kho Steel Fluidity: Txhim kho steel fluidity zoo heev thiab daws cov nozzle clogging.
 Txo cov pa roj thiab suav nrog: Txo cov roj cov ntsiab lus (H₂, N₂) hauv cov hlau, txo qis kev suav nrog.
 Tus nqi rov qab nce ntxiv: Cov ntsiab lus siab rov qab; non-combustible, non-explosive, thiab non-splashing.

2. Cast Iron Production

Nyob rau hauv cam khwb cia hlau ntau lawm, silicon aluminium barium calcium alloy tsis yog tsuas yog ib tug heev npaum inoculant tab sis kuj muaj zoo heev deoxidation thiab desulfurization los.

Application Scenario:

Grey Cam khwb cia hlau: Txhawb nqa graphitization, txhim kho graphite morphology thiab kev faib tawm, thiab txhim kho cov cuab yeej cuab tam ntawm castings.
