Cov khoom siv raw rau cov hlau ntshiab feem ntau suav nrog hlau ore, coke thiab limestone. Hlau ore yog cov khoom siv tseem ceeb rau kev ua hlau, thiab feem ntau yog hematite (Fe2O3) thiab magnetite (Fe3O4). Ua ntej smelting, hlau ore yuav tsum tau mus los ntawm cov txheej txheem xws li beneficiation, crushing, sib tsoo thiab sintering los txhim kho nws qib thiab tshem tawm impurities. Lub luag haujlwm ntawm coke yog muab cua sov thiab tsim cov neeg ua haujlwm txo cov pa roj carbon monoxide, thaum limestone yog siv rau kev tshem tawm slag thiab tshem tawm gangue, pab cais cov hlau thiab impurities tsim los ntawm smelting.
Tsis tas li ntawd, cov tshuaj muaj pes tsawg leeg ntawm cov hlau ntshiab muaj ib qho tseem ceeb ntawm nws cov kev ua tau zoo. Piv txwv li, cov ntsiab lus hlau ntawm YT01 raw cov hlau ntshiab mus txog 99.9% lossis ntau dua, thiab nws kuj muaj cov pa roj carbon tsawg heev (C), phosphorus (P) thiab sulfur (S) cov ntsiab lus, uas ua rau nws haum rau ntau yam txheej txheem smelting. Raw ntshiab hlau yog xa mus rau ntau yam ntaub ntawv, xws li nruam casting slabs, square steel, ca steel, round tuav, thiab lwm yam, thiab yog dav siv nyob rau hauv zus tau tej cov precision alloys, hluav taws xob alloys, mos sib nqus, amorphous alloys thiab mus tas li sib nqus hlau alloys.
