Manganese Hlau

manganese hlau

 

Manganese hlau(FeMn) yog ib qho hlau uas muaj hlau (Fe) thiab manganese (Mn), feem ntau yog siv hauv steel ntau lawm. FeMn feem ntau muaj nyob nruab nrab ntawm 65% thiab 80% manganese, thiab nyob ntawm daim ntawv thov, nws cov ntsiab lus carbon tuaj yeem nyob ntawm qis carbon (<0.5%) to high carbon (2%-8%). FeMn is a vital alloying additive in the steel industry, not only improving the mechanical properties of steel, but also imparting resistance to wear and corrosion.

 

Kev siv thaj chaw ntawmManganese hlau

Manganese hlaumuaj ntau yam kev siv hauv kev lag luam steel, feem ntau hauv cov hauv qab no:

Deoxidizer thiab desulphuriser: Manganese hlau muaj cov nyhuv deoxidising zoo hauv cov hlau, nws reacts nrog oxygen hauv cov hlau los tsim manganese oxide, yog li txo cov pa oxygen hauv cov hlau. Tsis tas li ntawd, manganese kuj tseem sib xyaw nrog sulfur los tsim manganese sulfide, uas txo cov sulfur cov ntsiab lus ntawm cov hlau thiab tiv thaiv kub embrittlement.

Alloying khoom additives: Manganese nyob rau hauv FeMn txhim kho lub hardenability, lub zog thiab hardness ntawm cov hlau, raws li zoo raws li nws tsis kam mus hnav thiab corrosion.

Kev tsim khoom ntawm ntau hom hlau: Manganese hlau yog siv nyob rau hauv zus tau tej cov carbon, alloy, stainless thiab cuab yeej steels. Los ntawm kev kho cov ntsiab lus manganese, cov khoom sib txawv ntawm cov hlau tuaj yeem ua tau raws li ntau yam kev xav tau ntawm engineering thiab kev lag luam kev lag luam.

Classification ntawm manganese hlau

 

 

FeMntuaj yeem muab faib ua pawg hauv qab no raws li cov ntsiab lus carbon:

 

High Carbon Manganese hlau (HC FeMn):Cov ntsiab lus carbon 2-8 ib xees. Nws yog ib qho uas feem ntau siv carbon steel thiab tuaj yeem txhim kho hardness thiab lub zog ntawm cov hlau.

 

Medium Carbon Manganese hlau (MC FeMn):Cov ntsiab lus carbon yog 1-2%. Cov khoom no tuaj yeem siv rau hauv kev tsim cov hlau uas muaj cov pa roj carbon tshwj xeeb, xws li cov qauv hlau thiab cov cuab yeej steel.

 

Tsawg Carbon Manganese hlau (LC FeMn):Cov ntsiab lus carbon tsawg dua 0.5%. Cov khoom siv no feem ntau yog siv hauv cov hlau tshwj xeeb, stainless hlau, thiab lwm yam, nrog rau kev tiv thaiv corrosion zoo heev.
