1. Grain Refinement nyob rau hauv Aluminium Alloys:
- Txhim kho Mechanical Properties: Aluminium Calcium master alloys feem ntau yog siv los ua grain refiners hauv kev tsim cov txhuas alloys. Qhov sib ntxiv ntawm calcium rau txhuas pab ua kom zoo dua cov qauv nplej thaum lub sij hawm solidification, ua rau kev txhim kho cov khoom siv xws li kev muaj zog ntxiv, zoo dua ductility, thiab txhim kho qhov chaw tiav. Cov txheej txheem kho kom zoo no yog qhov tseem ceeb tshwj xeeb hauv kev tsim cov khoom lag luam zoo aluminium, xws li cov siv hauv aerospace, tsheb, thiab kev siv cov qauv.
2. Deoxidizing Agent hauv Steelmaking:
- Txhim kho Steel Zoo: Al-Ca master alloys yog siv los ua deoxidizing cov neeg ua haujlwm hauv steelmaking. Calcium pab tshem tawm cov pa oxygen los ntawm cov hlau molten, uas txo qhov tsim ntawm cov hlau tsis muaj hlau uas tuaj yeem ua rau cov hlau tsis muaj zog. Kev siv Aluminium Calcium alloys hauv cov txheej txheem no pab tsim cov hlau huv, zoo dua qub nrog cov khoom siv kho kom zoo dua qub. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tsim cov hlau tshwj xeeb uas siv rau hauv cov ntawv thov tseem ceeb, xws li hauv kev tsim cov choj, cov kav dej, thiab cov khoom siv tsheb loj.
3. Corrosion Resistance nyob rau hauv Aluminium Alloys:
- Ntev Lifespan nyob rau hauv ib puag ncig hnyav: Ntxiv cov calcium rau txhuas alloys tuaj yeem txhim kho lawv cov kev tiv thaiv corrosion, ua rau lawv tsim nyog rau siv nyob rau hauv ib puag ncig uas lawv raug corrosive agents, xws li hauv marine thiab industrial daim ntaub ntawv. Qhov no txhim kho kev tiv thaiv corrosion pab ua kom lub neej ntev ntawm cov khoom siv txhuas thiab txo cov nqi tu, ua rau Al-Ca alloys xaiv rau cov khoom siv hauv qhov chaw hnyav.
4. Kev siv Casting thiab Foundry:
- Txhim kho Castability thiab txo qhov tsis xws luag: Hauv kev lag luam casting, Aluminium Calcium master alloys yog siv los txhim kho cov castability ntawm aluminium alloys. Qhov sib ntxiv ntawm calcium tuaj yeem txo qhov tsim ntawm cov theem tsis tsim nyog thiab txhim kho cov fluidity ntawm molten alloy, ua rau tsawg dua qhov tsis xws luag thiab cov khoom cam khwb cia zoo dua. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev tsim cov complex castings siv nyob rau hauv automotive thiab aerospace Cheebtsam, qhov twg precision thiab kev ntseeg tau yog ib qho tseem ceeb.
