1. Haum rau cov pa roj carbon tsawg cov qauv txheej txheem steel, tshwj xeeb tshaj yog tsim nyog rau cov hlau tsis zoo, tsis hloov cov qauv txheej txheem steelmaking, ua kom zoo dua cov alloy, txhim kho qhov tseem ceeb ntawm cov hlau, txo tus nqi ntawm cov steelmaking alloy, thiab muaj cov txiaj ntsig kev lag luam pom tseeb. Cov.
2. Kev siv cov pa roj carbon monoxide qis thiab nruab nrab cov pa roj carbon hlau ferromanganese Cov khoom no yog cov khoom siv tseem ceeb rau kev ua cov hlau tshwj xeeb thiab cov vuam sib dhos xws li steel hlau, siab kub tiv taus steel, cov hlau tsis zoo thiab cov cuab yeej steel.
3. Microcarbon ferromanganese, qis carbon ferromanganese, nruab nrab carbon manganese hlau qib thiab tshuaj lom neeg muaj pes tsawg leeg
4, ntim thiab cov qhov loj me: raws li tus neeg siv khoom xav tau, tuaj yeem siv rau hauv cov pob loj, ob txheej-lis 50kg yas ntim hnab, lub hnab ntim 1000kg thiab lwm yam. Muaj cov ntau thiab tsawg ntawm 10 txog 100 hli lossis hauv cov blocks ntuj.
