Txawm hais tias siv rau hauv daim ntawv pob rau cov kev kho mob ib txwm siv lossis ua cov hlau cored rau kev txhaj tshuaj meej, tus nqi nws ntxiv rau cov txheej txheem tsim khoom yog qhov tsis lees paub.

Yog tias koj tab tom nrhiav kom ua kom zoo dua koj cov haujlwm steelmaking, ntsuas koj cov tswv yim ntxiv tam sim no yog thawj kauj ruam. Xav txog kev hloov mus rau high-purity calcium silicon qib los yog siv cov cuab yeej siv xaim xaim los ua kom cov nqi rov qab zoo tshaj plaws. Kev koom tes nrog cov neeg muab kev ntseeg siab uas ua raws li cov qauv kev ua tau zoo ua kom muaj kev ua tau zoo thiab txhawb nqa koj lub hom phiaj kev tsim khoom mus sij hawm ntev.
