Dab tsi yog qhov txawv ntawm ferromanganese?

Ferromanganese feem ntau muab faib ua tsib pawg: siab-carbon ferromanganese, nruab nrab-carbon ferromanganese, qis-carbon ferromanganese, metallic manganese, thiab ferromanganese nitride. Qhov kev faib tawm tshwj xeeb yog nyob ntawm cov ntsiab lus carbon thiab lwm cov khoom xyaw.

1. Siab -carbon ferromanganese

• Cov ntsiab lus carbon: Feem ntau qis dua 7.0%, cov qib uas muaj xws li FeMn68C7.0

• Manganese cov ntsiab lus: 65% mus rau 76%

• Kev siv tseem ceeb: Deoxidizer thiab alloying additive rau cov hlau zoo tib yam, txhim kho steel hardness thiab hnav tsis kam

• Cov txheej txheem tsim khoom: Lub tshuab hluav taws xob tawg lossis lub tshuab hluav taws xob smelting, tus nqi qis dua

2. Nruab nrab-carbon ferromanganese

• Cov ntsiab lus carbon: 1.0% txog 1.5%

• Manganese cov ntsiab lus: 75% mus rau 85%

• Cov yam ntxwv tseem ceeb: Cov ntsiab lus carbon tsawg, tsis muaj leej faj thiab phosphorus impurities

• Cov chaw siv: tshwj xeeb steel smelting, xws li iav steel thiab bearing steel

3. Tsawg-carbon ferromanganese

• Cov ntsiab lus carbon: qis dua 0.5%, tswj nruj ntawm 0.2% thiab 0.5%

• Manganese cov ntsiab lus: 80% mus rau 90%

• Cov kev cai tshwj xeeb: Yuav tsum muaj cov txheej txheem kho kom zoo kom txo tau cov ntsiab lus carbon

• Kev siv tseem ceeb: Kev tsim cov hlau tsis muaj steel thiab siab -lub zog qis- hlau alloy (HSLA)

4. Hlau Manganese

• Manganese cov ntsiab lus: 93% mus rau 99.8%

• Cov ntsiab lus carbon: tsawg heev (feem ntau qis dua 0.1%)

• Cov txheej txheem ntau lawm: Electrolytic los yog silicothermic txoj kev

• Daim ntawv thov scenarios: Raw khoom rau siab -kub alloys thiab precision alloys

5. Ferromanganese Nitride

• Cov ntsiab lus tseem ceeb: Nitrogen cov ntsiab lus 4% txog 6%

• Manganese cov ntsiab lus: 70% mus rau 85%

• Tshwj xeeb muaj nuj nqi: Raws li ib tug nitrogen alloying tus neeg saib xyuas, kev txhim kho lub zog thiab corrosion kuj ntawm stainless hlau

• Cov txheej txheem ntau lawm: Solid nitriding lossis kua nitriding

Lus Cim: Cov kev faib tawm saum toj no yog raws li lub teb chaws tus qauv tam sim no GB/T 3795-2014 "Ferromanganese". Hauv kev tsim khoom tiag tiag, qhov sib xyaw ua ke yuav raug kho raws li cov neeg siv xav tau. Thaum xaiv ferromanganese hom, steel qib yuav tsum tau, cov nqi tsim khoom, thiab cov txheej txheem yuav tsum tau txiav txim siab. Thaum siv cov khoom siv xws li cov tshuab hluav taws xob, kev ua raws li cov txheej txheem kev nyab xeeb yuav tsum tau ua kom tsis txhob muaj cov khoom kub kub los ntawm kev txaws.
