Tsawg Carbon Ferro Manganese Phau Ntawv Qhia: Cov Khoom, Siv & Kev Pom Zoo 

Tsawg carbon ferro manganese yog ib qho tseem ceeb ferroalloy siv feem ntau hauv steelmaking los txo cov ntsiab lus carbon thaum ntxiv manganese tseem ceeb. Tsis zoo li cov qauv qib, qhov sib txawv no muaj tsawg dua 0.7% carbon, ua rau nws tseem ceeb rau kev tsim cov khoom muaj zog, cov pa roj carbon tsawg thiab cov khoom tshwj xeeb stainless hlau. Nws ua hauj lwm raws li ib tug meej deoxidizer thiab desulfurizer, xyuas kom meej cov khoom hlau zaum kawg raws li nruj mechanical thiab tshuaj specifications tsis muaj kev cuam tshuam cov qauv kev ntseeg.

Dab tsi yog Low Carbon Ferro Manganese?

Cov pa roj carbon tsawg ferro manganese yog cov hlau alloy uas tsim los ntawm manganese thiab hlau, tshwj xeeb los ntawm nws cov ntsiab lus txo qis dua piv rau cov pa ferro manganese. Cov txheej txheem tsim khoom feem ntau suav nrog kev txo qis silicothermic lossis cov txheej txheem oxygen tshuab kom tshem tawm cov pa roj carbon ntau dhau los ntawm cov pa roj carbon ntau.

Cov khoom no ua raws li ib tug tseem ceeb additive nyob rau hauv niaj hnub metallurgy. Nws lub luag haujlwm tseem ceeb yog qhia cov manganese rau hauv molten steel da dej qhov twg cov pa roj carbon ntau yuav tsum nyob tsawg. Manganese txhim kho hardenability, tensile lub zog, thiab hnav tsis kam, uas yog cov khoom tseem ceeb rau kev siv engineering siab heev.

Kev lag luam paub qhov txawv ntawm cov hlau no raws li kev txwv nruj nruj. Thaum tus qauv ferro manganese yuav muaj txog li 7.5% carbon, lub tsawg carbon variant nruj me ntsis ua raws li cov kev txwv feem ntau qis dua 0.7%, nrog rau qee cov qib qis qis mus txog qhov qis dua. Qhov kev txiav txim siab no tso cai rau cov kws tsim cov hlau ua kom zoo-tsim alloy cov khoom sib xyaw yam tsis tau rov ua dua cov pa roj carbon tsis zoo.

Cov Txheej Txheem Txheej Txheem Txheej Txheem Tseem Ceeb

Nkag siab txog cov tshuaj pleev ib ce yog qhov tseem ceeb rau kev yuav khoom thiab kev siv. Cov muaj pes tsawg leeg sib txawv me ntsis nyob ntawm cov qib tshwj xeeb xav tau los ntawm cov neeg siv kawg, tab sis cov qauv kev lag luam dav dav tswj xyuas nruj ntawm cov impurities.

• Manganese (Mn): Feem ntau yog nyob nruab nrab ntawm 80% thiab 90%, muab cov txiaj ntsig zoo ntawm cov tub ntxhais alloying.
