1. Taw qhia rau High Carbon Ferro Manganese
High Carbon Ferro Manganese(HCFeMn) yog manganese-muaj ferroalloy, feem ntau muaj manganese, hlau thiab carbon, thiab feem ntau muaj 70-80% manganese thiab 6-8% carbon. Kev tsim cov pa roj carbon ntau ferromanganese yog ua tiav los ntawm smelting manganese ore nrog hlau ore, coke los yog lwm yam txo cov neeg ua hauj lwm hauv hluav taws xob arc rauv los yog blast furnaces. Vim nws cov ntsiab lus siab manganese thiab cov ntsiab lus carbon tsawg, nws ua lub luag haujlwm tseem ceeb hauv kev lag luam metallurgy.
2. Kev siv tseem ceeb ntawm high-carbon ferromanganese
2.1 Hlau thiab hlau kev lag luam
Deoxidizer thiab desulphuriser: Nyob rau hauv cov txheej txheem ntawm hlau thiab steel ntau lawm,siab carbon ferromanganesefeem ntau yog siv los tshem tawm cov pa oxygen thiab sulfur ntawm hlau. Manganese muaj zog deoxidising peev xwm, uas tuaj yeem txo cov pa oxygen hauv cov hlau thiab txhim kho cov hlau zoo. Tsis tas li ntawd, manganese muaj zog affinity rau leej faj thiab muaj peev xwm tsim manganese sulphides, yog li txo cov sulfur ntsiab lus nyob rau hauv steel thiab txhim kho cov kub ua hauj lwm zog ntawm hlau.
Alloying caij: Manganese yog ib qho tseem ceeb alloying caij, ntxiv cov manganese tsim nyog nyob rau hauv cov hlau tuaj yeem txhim kho lub zog, toughness thiab hnav tsis kam ntawm hlau.High-carbon ferromanganesefeem ntau yog siv rau hauv kev tsim cov carbon, stainless thiab lwm yam hlau alloys. Piv txwv li, hauv kev tsim cov cuab yeej hlau thiab cov qauv hlau, cov pa roj carbon ferromanganese siab tuaj yeem txhim kho cov khoom siv kho tshuab thiab corrosion tsis kam ntawm hlau.
2.2 Cov khoom siv vuam
Cov khoom siv vuam: Hauv kev lag luam vuam,siab carbon ferromanganesekuj yog siv los tsim cov khoom siv vuam. Nws yog siv los ua ib qho ntxiv los ua kom lub zog thiab tawv tawv ntawm cov khoom siv vuam thiab txhim kho cov khoom ntawm cov pob qij txha, tshwj xeeb tshaj yog tseem ceeb hauv kev tsim cov welding rods xav tau lub zog siab.
2.3 Foundry kev lag luam
Cam khwb cia hlau ntau lawm: Hauv kev lag luam foundry,siab carbon ferromanganesetuaj yeem siv rau hauv kev tsim cov hlau cam khwb cia. Qhov sib ntxiv ntawm cov pa roj carbon ntau ferromanganese txhim kho cov khoom siv ntawm cov hlau cam khwb cia, txhim kho nws lub zog thiab hnav tsis kam, thiab tseem pab txo qhov porosity thiab lwm yam tsis xws luag hauv castings.
3. Cov lus xaus
Raws li ib qho tseem ceeb ferroalloy,siab carbon ferromanganesemuaj ntau yam kev siv nyob rau hauv steel ntau lawm, vuam cov ntaub ntawv thiab foundry kev lag luam. Nws tsis yog tsuas yog ib qho tseem ceeb deoxidiser thiab alloying caij hauv steel ntau lawm, tab sis kuj plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv hlau thiab cov khoom siv vuam. Nrog rau kev loj hlob ntawm kev lag luam kev xav tau thiab kev ua haujlwm thev naus laus zis, kev lag luam zeem muag ntawm cov pa roj carbon ferromanganese siab yuav dav dua.
