Lub ntsiab raw khoom ntawm calcium silicon cored hlau yog calcium silicon hmoov. Calcium silicon hmoov yog siv los ua cov khoom tseem ceeb, thiab cov tawv nqaij sab nrauv yog cov tawv nqaij steel, uas yog nias los ntawm lub tshuab xov hlau.
Nws tuaj yeem ua kom huv hauv daim ntawv ntawm cov hlau, txhim kho cov castability ntawm cov hlau molten, txhim kho cov kev pabcuam ntawm cov hlau, thiab txhim kho cov txiaj ntsig ntawm cov hlau, txo cov alloy noj, txo tus nqi ntawm steelmaking, thiab cov txiaj ntsig zoo ntawm kev lag luam.
Molten steel yuav tsim ntau cov oxides los yog deoxidation khoom nyob rau hauv tus txheej txheem ntawm smelting thiab refining. Yog tias cov oxides tsis raug tshem tawm, lawv yuav ua rau muaj kev phom sij rau cov hlau tsis zoo. Yog li ntawd, calcium kab yog pub rau hauv cov kua hlau, thiab lub zog reducibility ntawm Ca yog siv los txo cov hlau oxides hauv steel nrog deoxidation cov khoom los tsim calcium oxides. Los yog nrog lwm cov oxides yooj yim rau ntab nyob rau hauv cov hlau uas tsis muaj melting point compound, uas yog, Ca oxide denaturation, thiaj li yuav txo tau cov oxides nyob rau hauv steel, purify cov kua hlau, txhim kho cov purity ntawm hlau. Cov tub ntxhais tseem ceeb silicon calcium hlau muaj cov yam ntxwv ntawm kev tswj tau yooj yim, khaws cia yooj yim, tsis tshua muaj nqi ntawm calcium kev kho mob thiab cov nyhuv ruaj khov ntawm kev kho calcium.
