Khoom Description
Covcalcium silicon, tsis hu ua silicified calcium, muaj 22 mus rau 35% calcium thiab 60 mus rau 65% silicon. YB 525-65 qhia tias cov ntsiab lus calcium yuav tsum tsis pub tsawg dua 31%, 28%, thiab 24% raws li. Nws yog tsuas yog siv los ua inoculant rau cam khwb cia hlau. Lub peev xwm txo qis ntawm silicon-calcium alloy muaj zog heev thiab tseem siv los ua cov deoxidizer rau cov hlau zoo. Raws li deoxidizer rau hlau, silicon-calcium-barium alloy los yog silicon-calcium-barium-aluminium alloy, los yog silicon-calcium-manganese alloy feem ntau yog siv.
Cov khoom zoo
Ntxiv nrog rau magnesium thiab cov hlau tsis tshua muaj hauv ntiaj teb, calcium kuj tuaj yeem txo cov pa oxygen thiab sulfur cov ntsiab lus uas cuam tshuam kev tsim cov spheroidized graphite, txhawb cov spheroidization ntawm graphite hauv castings. Calcium yog dav siv los ua denaturant hauv steelmaking thiab alloys. Kev kho cov hlau yaj nrog cov calcium ntshiab lossis nws cov alloys tuaj yeem txhim kho lub cev thiab tshuaj lom neeg ntawm cov hlau, uas yog qhov zoo rau kev txhim kho cov morphology ntawm oxide thiab sulfide inclusions nyob rau hauv cov hlau tiav thiab castings.
Cov khoom nta
Calcium silicon alloy yog cov khoom sib xyaw ua ke ntawm cov khoom silicon, calcium thiab hlau. Nws yog ib qho zoo tagnrho deoxidizer thiab desulfurizer. Nws cov kev ua tau zoo muaj xws li:
1. Muaj peev xwm deoxidation muaj zog: Silicon thiab calcium muaj affinity siab rau oxygen, thiab calcium muaj affinity siab rau sulfur. Cov khoom deoxidation thiab desulfurization tau yooj yim ntab thiab tshem tawm, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov hlau thiab txhim kho cov yas thiab cuam tshuam rau cov hlau.
2. Yooj yim rau nqus dej thiab pulverize: Ua tib zoo saib xyuas cov dej noo-pov thawj thaum thauj thiab khaws cia.
3. Ua kom muaj zog exothermic nyhuv: Calcium hloov mus rau hauv calcium vapor nyob rau hauv molten steel, uas stirs lub molten steel thiab yog zoo rau lub floating ntawm non-metallic inclusions.
4. Hloov cov duab thiab cov khoom ntawm cov khoom tsis yog xim hlau: Yog li ntawd, calcium silicon alloy yog siv los tsim cov hlau huv, cov hlau zoo uas tsis tshua muaj oxygen thiab cov ntsiab lus sulfur, thiab kev ua haujlwm tshwj xeeb steel nrog cov ntsiab lus tsis tshua muaj oxygen thiab leej faj.
5. tuaj yeem siv los ua tus neeg sawv cev kub nce ntxiv: Calcium silicon alloy yog qhov ua tau zoo ntawm qhov kub thiab txias thiab siv dav hauv kev tsim khoom ntawm ntau hom steel, tshwj xeeb alloys thiab cam khwb cia hlau.
6. tuaj yeem siv los ua ib qho inoculant: Hauv cam khwb cia hlau ntau lawm, calcium silicon alloy tuaj yeem siv los ua deoxidizer, desulfurizer thiab inoculant, thiab kuj yog tus neeg sawv cev kub nce ntxiv.
