Calcium-silicon alloy yog cov khoom siv sib xyaw ua ke uas muaj feem ntau ntawm silicon, calcium, hlau thiab lwm yam kab kawm. Hauv kev lag luam steelmaking, calcium-silicon alloy feem ntau yog siv los ua cov khoom sib xyaw deoxidiser thiab desulphuriser.
Piv nrog rau lwm yam steelmaking deoxidisers, calcium nyob rau hauv calcium-silicon alloy muaj ib tug muaj zog affinity rau silicon thiab oxygen, thiab kuj muaj zog affinity rau leej faj thiab nitrogen. Yog li ntawd, calcium-silicon alloy yog ib qho zoo heev compound deoxidiser thiab desulphuriser. Thaum cov hlau tau tsim, ntxiv cov nyiaj calcium-silicon alloy tsis yog tsuas yog ua tiav cov txiaj ntsig zoo deoxidisation, tab sis kuj ua rau cov khoom deoxidised ntab thiab tawm tau yooj yim, sai sai ntxuav cov hlau molten thiab txhim kho cov hlau zoo. Calcium silicon alloy tuaj yeem deoxidise molten hlau thaum lub sij hawm steelmaking, ua kom tiav deoxidation ntau dua thiab cov txiaj ntsig zoo dua nrog cov calcium. Nws tuaj yeem txhim kho cov duab ntawm kev suav nrog hauv cov hlau molten, ua kom tshem tawm slag yooj yim dua thiab yooj yim dua. Nyob rau hauv cov nqe lus ntawm casting, tus tshiab calcium silicon alloy tuaj yeem txhim kho cov khoom ntws ntawm cov hlau molten, tso cai rau cov tshuaj txaus txaus ntawm cov ntsiab lus.
