c. Kev txo qis: Cov pa roj carbon hauv coke cuam tshuam nrog oxygen hauv cov khoom siv raw, ua rau txo qis cov tshuaj tiv thaiv uas hloov manganese thiab hlau oxides rau hauv daim ntawv hlau.
d. Alloy Tsim: Cov hlau molten, muaj hlau, manganese, thiab lwm yam khoom, sau rau hauv qab ntawm lub cub tawg. Cov impurities, hu ua slag, ntab saum toj thiab raug tshem tawm.

3. Kev kho kom zoo:Tom qab cov txheej txheem smelting, cov hlau yuav raug kho kom ua tiav qhov xav tau muaj pes tsawg leeg thiab purity. Refining muaj ntau yam txuj ci xws li tshuab oxygen los ntawm cov hlau molten los yog siv cov fluxes tshem tawm impurities.

4. Solidification thiab crushing:Thaum qhov xav tau muaj pes tsawg leeg tau tiav, molten ferromanganese yog nchuav rau hauv pwm los yog cam khwb cia rau hauv ingots. Tom qab solidification, lub alloy yog crushed rau hauv me me pieces kom yooj yim tuav thiab thauj.

5. Kev Tswj Xyuas Zoo:Thoob plaws hauv cov txheej txheem tsim khoom, kev tswj xyuas kev ua tau zoo yog siv los ua kom cov ferromanganese ua tau raws li cov qauv xav tau. Lub alloy yog kuaj rau tshuaj muaj pes tsawg leeg, txhua yam khoom, thiab tej impurities uas yuav cuam tshuam rau nws kev ua tau zoo.

Kev siv thiab qhov tseem ceeb:

Ferromanganese tau siv dav hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb. Cia peb tshawb nrhiav cov kev siv tseem ceeb ntawm no alloy:

1. Steel Production:Daim ntawv thov loj tshaj plaws ntawm ferromanganese yog nyob rau hauv kev lag luam steelmaking. Nws ua haujlwm ua deoxidizer thiab desulfurizer, pab txhim kho cov hlau zoo. Tsis tas li ntawd, ferromanganese kho cov hlau cov khoom siv, xws li hardness thiab lub zog, ua rau nws haum rau ntau lub hom phiaj, nrog rau kev tsim kho, tsheb, thiab kev tsim khoom.

2. Stainless hlau Alloying:Ferromanganese yog siv los ua tus neeg sawv cev alloying hauv kev tsim cov hlau tsis muaj steel. Stainless hlau muaj cov ntsiab lus tshwj xeeb ntawm chromium, thiab ferromanganese pab kom ua tiav cov tshuaj lom neeg xav tau.
