Nruab nrab carbon ferromanganese yog ib qho ntawm cov khoom siv feem ntau siv hauv kev tsim cov hlau. Vim nws cov ntsiab lus siab manganese thiab cov ntsiab lus tsis muaj leej faj, nws tuaj yeem txhim kho hardness, lub zog thiab toughness ntawm hlau. Nws yog dav siv nyob rau hauv kev tsim ntawm ntau hom hlau, xws li cov qauv steel, hnav-resistant steel, weathering steel, thiab lwm yam, thiab yog dav siv nyob rau hauv kev tsim kho, txuas hniav, tsheb, machinery thiab lwm yam lag luam.

Nws yog dav siv hauv kev lag luam metallurgical thiab muaj ntau yam haujlwm tseem ceeb.

1. Ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau alloy.

Los ntawm kev ntxiv ib qho kev faib ua feem ntawm nruab nrab carbon ferromanganese rau steel, hardness, lub zog thiab hnav tsis kam ntawm cov hlau tuaj yeem txhim kho. Cov pa roj carbon monoxide nyob rau hauv nruab nrab carbon ferromanganese tuaj yeem tsim cov tshuaj tov, ua kom lub zog thiab hardness ntawm hlau; Nyob rau tib lub sijhawm, cov ntsiab lus manganese tuaj yeem tsim cov khoom siv nrog cov hlau, thiab muaj cov txiaj ntsig ntawm refining nplej thiab ntxiv dag zog, yog li txhim kho lub zog thiab hnav tsis kam ntawm hlau. Cov pa roj carbon nruab nrab ferromanganese ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv uas xav tau lub zog siab thiab hnav tsis kam xws li tsheb, nkoj, thiab kev tsheb ciav hlau.

2. Nws tuaj yeem txhim kho qhov toughness thiab plasticity ntawm cov hlau.

Los ntawm kev ntxiv qhov tsim nyog ntawm nruab nrab carbon ferromanganese, cov pa roj carbon ntsiab lus hauv cov hlau tuaj yeem raug txo kom tsawg, yog li txo qhov brittleness ntawm cov hlau. Nyob rau tib lub sijhawm, manganese cov ntsiab lus tuaj yeem tsim cov sib txuas nrog cov sulfur hauv cov hlau, txo cov ntsiab lus ntawm cov sulfur hauv cov hlau thiab ntxiv dag zog rau cov hlau. Toughness thiab plasticity yog qhov tshwm sim ntawm cov yas deformation thiab tawg tsis kam ntawm cov ntaub ntawv thaum muaj kev ntxhov siab. Rau cov hlau hauv kev lag luam metallurgical, kev txhim kho hauv toughness thiab plasticity tuaj yeem txhim kho cov txheej txheem thiab kev pabcuam lub neej ntawm cov khoom.

3. tuaj yeem txhim kho corrosion ntawm cov hlau.

Manganese tuaj yeem tsim cov tebchaw ruaj khov nrog oxygen thiab sulfur hauv cov hlau, tiv thaiv cov pa oxygen thiab sulfur los ntawm kev ua kom cov hlau txuas ntxiv, yog li txhim kho corrosion ntawm cov hlau. Tshwj xeeb tshaj yog nyob rau hauv ib co hnyav corrosive ib puag ncig, xws li hlau nyob rau hauv marine ib puag ncig, qhov sib ntxiv ntawm nruab nrab carbon ferromanganese yuav ho txhim kho corrosion kuj ntawm hlau thiab ntev kev pab cuam lub neej ntawm steel.

4. Nws tuaj yeem txhim kho qhov weldability ntawm cov hlau.

Thaum lub sij hawm tsim thiab ua cov hlau, vuam ua haujlwm feem ntau yuav tsum tau. Qhov sib ntxiv ntawm cov pa roj carbon monoxide ferromanganese tuaj yeem txo qhov kub kub tawg ntawm cov hlau, txhim kho vuam kev ua tau zoo, thiab txhim kho weldability ntawm hlau. Qhov no muaj qhov cuam tshuam tseem ceeb rau kev ua cov hlau thiab cov txheej txheem tsim khoom.

Cov pa roj carbon ferromanganese nruab nrab kuj muaj qee yam haujlwm. Piv txwv li, nruab nrab carbon ferromanganese tuaj yeem siv los ua cov khoom siv raw rau kev npaj steel ingots rau kev tsim cov hlau alloy thiab cov hlau tshwj xeeb. Tsis tas li ntawd, nruab nrab carbon ferromanganese kuj tseem siv tau los ua ib qho tseem ceeb metallurgical txo tus neeg saib xyuas kom txo cov hlau oxides thaum lub sij hawm metallurgical txheej txheem, yog li tshem tawm cov hlau ntshiab.
