Ferro Manganese Tsawg Carbon
Ferro Manganese Tsawg Carbon
Ferro Manganese Tsawg Carbon, feem ntau abbreviated li FeMnLC, yog ib tug alloy siv nyob rau hauv lub steelmaking kev lag luam rau nws cov khoom tshwj xeeb thiab muaj peev xwm los txhim kho cov hlau zoo. Nws yog feem ntau tsim los ntawm hlau (Fe), manganese (Mn), thiab carbon (C), nrog cov ntsiab lus qis ntawm carbon.
Ferro Manganese Tsawg Carbon Khoom Taw Qhia
Tsawg carbon ferromanganese yog ferroalloy ua los ntawm cov txheej txheem thermal alumino hauv kev lag luam steel. Nws yog ib qho qis-carbon variant ntawm ferromanganese uas muaj ib tug me me ntawm manganese piv rau nws cov high-carbon counterpart. Tsawg carbon ferromanganese yog siv dav hauv kev lag luam steel los tsim cov cuab yeej hlau, siab zog austenitic tsis-sib nqus hlau thiab cov qauv hlau. Nws kuj yog siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv steel ntau lawm. Ferro Manganese Tsawg Carbon yog qhov zoo!
Hauv kev tsim cov ferro manganese tsawg carbon, sib tov ntawm manganese thiab hlau oxides yog rhuab mus rau ib tug kub kub nyob rau hauv lub xub ntiag ntawm carbon nyob rau hauv daim ntawv ntawm carbon monoxide. Cov txheej txheem no yog hu ua txheej txheem alumino-thermal. Qhov kub siab yog siv los oxidize cov hlau rau manganese oxide, thaum cov pa roj carbon hloov mus rau carbon dioxide.
Cov pa roj carbon tsawg ferromanganese tsim los ntawm cov txheej txheem no muaj cov ntsiab lus carbon tsawg dua 0.7 feem pua, uas yog qis dua li cov pa roj carbon ferromanganese ntau. Qhov no ua rau nws yog ib qho zoo tagnrho alloy rau steelmaking daim ntaub ntawv uas yuav tsum tau cov ntsiab lus carbon tsawg. Nws kuj muaj qhov siab melting point ntawm 1245 degree thiab kub kub ntawm 2150 degree, ua rau nws muaj zog thiab ruaj khov alloy.
Ferromanganese muaj kev sib raug zoo rau cov pa oxygen thiab tuaj yeem tsim cov manganese oxide ruaj khov nrog oxygen. Qhov no ua rau nws ua tau zoo heev deoxidizer thiab alloying tus neeg sawv cev hauv cov txheej txheem steelmaking. Thaum ntxiv rau cov hlau hauv qhov tsim nyog, nws nce qhov hardness, ductility, toughness thiab hnav tsis kam ntawm cov hlau. Vim li no, nws yog dav siv nyob rau hauv zus tau tej cov cuab yeej steel, high-strength austenitic non-magnetic steel thiab structural steel.
Nyob rau hauv xyoo tsis ntev los no, muaj ib tug qauv mus rau kev siv ntawm tsawg-carbon ferromanganese ua los ntawm converter, co xovxwm thiab oxygen tshuab. Cov txheej txheem no muaj zog ntau dua li cov txheej txheem ib txwm siv thiab txo cov ntsiab lus carbon ntawm ferromanganese. Qhov no tsis tau tsuas yog ua rau cov nqi txuag, tab sis kuj txo cov pa roj carbon hneev taw ntawm cov hlau.
