Txhim kho cov hlau zoo.
Nyob rau hauv kev siv ntawm silicon aluminium alloy nyob rau hauv steelmaking, cov khoom uas tsis yog-melting, tsawg melting point, yooj yim rau ntab, tuaj yeem txhim kho cov hlau zoo.
Ferrosilicon yog cov hlau thiab silicon alloy. Ferrosilicon yog coke, steel chips, quartz (los yog silica) ua raw cov ntaub ntawv, nrog hluav taws xob rauv smelting ua los ntawm ferrosilicon alloy. Vim tias silicon thiab oxygen yooj yim ua ke rau hauv silicon dioxide, yog li hlau silicon feem ntau siv los ua deoxidizer hauv steelmaking. Nyob rau tib lub sijhawm, vim qhov tso tawm ntawm cov cua sov ntau thaum SiO2 tsim tawm, nws kuj yog qhov zoo los txhim kho qhov kub ntawm cov hlau molten tib lub sijhawm.
