Kev siv cov silicon hauv silicon-calcium alloys:
Silicon yog cov khoom qub uas muaj ntau yam kev siv, tab sis nyob rau hauv cov calcium-silicon alloy, peb tsuas yog siv nws ntau hauv kev lag luam steelmaking. Cov silicon nyob rau hauv cov calcium-silicon alloy tuaj yeem txo cov hlau molten zoo heev thiab yog tus neeg sawv cev muaj zog vim tias muaj ntau cov pa oxygen hauv cov hlau molten thaum lub sij hawm steelmaking. Yog tias muaj cov pa oxygen ntau dhau, yuav muaj ntau cov oxides uas cuam tshuam rau qhov zoo ntawm cov hlau. Calcium-silicon alloy tuaj yeem tshem tawm cov pa tawm ntawm cov hlau sai sai, yog li tsim cov silicon dioxide, yog li nws muaj peev xwm ua kom huv cov hlau molten los txhim kho cov hlau zoo.
Kev siv cov calcium hauv calcium-silicon alloys:
Calcium yog ib qho tseem ceeb hauv kev tsim cov hlau. Nws lub hom phiaj tseem ceeb yog txhawm rau txhim kho cov dej ntws ntawm cov hlau molten thiab txhim kho lub zog thiab txiav cov khoom ntawm cov hlau tiav. Kev siv cov calcium-silicon alloys tuaj yeem tiv thaiv qhov txhaws ntawm qhov kais dej thiab tso cai rau kev kho kom zoo dua ntawm impurities hauv cov hlau molten. Kev lim dej txhim kho cov khoom ntawm cov hlau tiav.
