Khoom Taw Qhia
Silicon Zirconium Inoculant yog ib qho hlau-raws li kev sib xyaw inoculant feem ntau yog tsim los ntawm silicon thiab zirconium. Nws yog dav siv nyob rau hauv zus tau tej cov grey hlau thiab ductile hlau los txhim kho graphite nucleation, txhim kho microstructure stability, thiab txo qhov tsis xws luag casting.
Hom tshuaj muaj pes tsawg leeg
- Silicon (Si): 60% -75% - Lub hauv paus ntsiab lus muab kev muaj peev xwm graphitization muaj zog
- Zirconium (Zr): 1.5% -5.0% - Cov ntsiab lus tseem ceeb (qib ntau muaj 3% -6%)
- Cov khoom pabcuam: Calcium (Ca), Aluminium (Al), thiab Barium (Ba) txhua 0.5%–2.5%, muab kev sib koom ua ke deoxidation thiab tiv thaiv-fading teebmeem
- Hlau (Fe): Sib npaug
- impurities: S Tsawg dua lossis sib npaug rau 0.04%, P Tsawg dua lossis sib npaug rau 0.05%
- Daim ntawv khoom: 0.2-5 mm granules, haum rau hauv -kwj inoculation lossis ladle ntxiv hauv cov txheej txheem casting niaj hnub.

Ntsiab Function
Muaj peev xwm Nucleation muaj peev xwm
Zirconium tsim siab -melting- cov ntsiab lus sib txuas xws li ZrC, ZrO₂, thiab ZrN, uas ua tau zoo heev graphite nuclei. Qhov no ua rau kom cov eutectic hlwb ntau ntxiv thiab txhawb nqa cov graphite faib.
Strong Resistance rau Inoculation Fading
Cov nyhuv inoculation tseem nyob ruaj khov rau lub sij hawm ntev dua piv nrog cov pa inoculants, ua rau nws haum rau cov txheej txheem ntau lawm, loj casting ntim, thiab tuab -section castings.
Kev Txhaum Chill Formation
Silicon-zirconium inoculant zoo txo qis qis qis thiab txo qis qis qis, ua rau cov hlau grey kom tau txais cov khoom zoo thiab sib faib A- hom graphite.
Deoxidation, Desulfurization thiab Nitrogen Fixation
Nws muab kev ua kom muaj zog deoxidation thiab desulfurization kev ua tau zoo thaum kho cov nitrogen yaj hauv cov hlau molten. Qhov no pab tshem tawm nitrogen porosity, uas yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum siv cov khoom seem steel siab.
Microstructure Refinement
Los ntawm kev txhim kho graphite nucleation thiab matrix uniformity, lub inoculant txhim khu lub zog thiab toughness ntawm cam khwb cia hlau Cheebtsam.
Cov ntawv thov tseem ceeb
Grey Cam khwb cia hlau
Feem ntau siv nyob rau hauv kev tsim cov cav blocks, lub tog raj kheej taub hau, kis vaj tse, thiab tshuab cuab yeej txaj. Cov khoom siv no yuav tsum muaj lub zog siab, zoo airtightness, thiab tsawg tsawg qhov tsis xws luag.
Hlau Hlau
Tsim nyog rau qib siab -lub zog ductile hlau xws li QT700-2 thiab siab dua, nrog rau cov khoom siv loj siv hauv cov cua fais fab, cov khoom siv hluav taws xob nuclear, tsheb crankshafts, thiab lub log hubs. Silicon-zirconium inoculant pab stabilize nodularization thiab txo shrinkage defects.
High Scrap Ratio Melting
Thaum cov seem seem ntau tshaj 50%, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem carburizing, silicon -zirconium inoculant zoo tswj cov ntsiab lus nitrogen thiab txo cov nqi tsis kam lees.
Hauv -Kwj Inoculation
Nws yog qhov tsim nyog rau kev ua haujlwm puv puv puv kab, muab kev ruaj khov thiab kev ua haujlwm tsis sib xws nrog cov txheej txheem kev ntseeg tau zoo.
Daim ntawv qhia kev thov
Ntxiv tus nqi
Ladle lossis qhov cub ntxiv: 0.2% -0.6%
Hauv -kwj inoculation: 0.1%–0.3%
Kev ua tau zoo zoo
Piv nrog cov tshuaj FeSi-Ba lossis FeSi-Sr inoculants, silicon-zirconium inoculant muaj: muaj zog tiv thaiv inoculation fading zoo nitrogen tswj kev txhim kho casting zog
Pom zoo rau
