Cov pa roj carbon tsawg ferromanganese feem ntau yog siv hauv steelmaking, uas tuaj yeem txhim kho hardness thiab toughness ntawm steel thiab zoo deoxidize thaum lub sij hawm steelmaking txheej txheem. Tsawg-carbon ferromanganese yog ib qho tsim nyog smelting raw khoom rau ntau yam tshwj xeeb steels. Txoj kev tsim khoom ntawm cov pa roj carbon tsawg ferromanganese feem ntau yog txoj kev tawg rauv. Kev tsim cov pa roj carbon tsawg ferromanganese los ntawm blast furnace method yog ib txoj hauv kev ntau lawm. Txoj kev tsim khoom yog qhov pib zoo ib yam li cov hlau cam khwb cia. Lub hauv paus ntsiab lus yog rho manganese thiab hlau los ntawm ore.
Lub ntsiab ferroalloy raw cov ntaub ntawv ntawm tsawg carbon ferromanganese yog manganese ore, coke thiab flux, raws li zoo raws li combustion cua los yog oxygen enrichment. Cov ntaub ntawv raw yog thauj mus rau hauv lub cub tawg los ntawm lub qhov cub kub, thiab cov cua kub los yog cov pa oxygen-enriched yog cua tshuab mus rau hauv lub cub tawg los ntawm cov tuyeres kom hlawv cov coke kom tau qhov kub thiab txias, thiab txo cov roj reacts nrog cov ore. . Lub molten slag thiab hlau sau nyob rau hauv qab ntawm lub cub tawg thiab yog periodically tawm los ntawm lub slag thiab tapholes. Raws li tus nqi yog melted, reacted thiab tawm, tus nqi tshiab yog ntxiv tsis tu ncua thiab ntau lawm.
Tsawg-carbon ferromanganese muaj ib qho me me ntawm cov kab kawm, feem ntau yog manganese thiab hlau, nrog rau feem ntau txog 92%. Cov ntsiab lus carbon kuj tseem siab ntawm ferromanganese. Feem ntau hais lus, cov ntsiab lus ntawm cov pa roj carbon tsawg ferromanganese yog li 6% -7%. Kev tsim cov pa roj carbon monoxide siab ferromanganese ferrochromium feem ntau yog ua raws li cov txheej txheem tsim cov tshuab hluav taws xob, thiab cov pa roj carbon tsawg ferromanganese ferroalloys kuj tau siv dav hauv steelmaking. Tsawg carbon ferromanganese nyob rau hauv hluav taws xob furnaces yog tsuas yog siv raws li casting deoxidizer, desulfurizer thiab alloy additive. Tsawg carbon ferromanganese tsuas yog ntxiv thaum lub sij hawm casting. Feem ntau cov tsev steel mills siv silicomanganese, thiab qee qhov steel mills siv siab manganese.
Cov pa roj carbon ferromanganese nruab nrab yog cov yam ntxwv los ntawm cov ntsiab lus qis carbon. Cov pa roj carbon ferromanganese nruab nrab tuaj yeem siv rau hauv ntau qhov chaw, tab sis nws tseem siv dav hauv steelmaking. Manganese yog ib qho khoom zoo rau kev tsim steel. Cov pa roj carbon nruab nrab ferromanganese tuaj yeem txhim kho cov nqi hardness ntawm cov hlau hauv steelmaking thiab siv los tsim cov hlau tshwj xeeb, stainless hlau thiab lwm yam hlau tshwj xeeb. Tom qab kev kho tshwj xeeb, cov pa roj carbon monoxide ntawm nruab nrab carbon manganese hlau tuaj yeem raug txo kom txog li 0.2.
Vim yog cov yam ntxwv ntawm nruab nrab carbon ferromanganese, nws yog dav siv nyob rau hauv kev lag luam foundry, steel kev lag luam thiab steelmaking. Nws yog tsim los ntawm manganese thiab hlau. Ferromanganese yog deoxidizer thiab alloy khoom siv dav hauv steelmaking. Nws yog smelted los ntawm manganese ore los ntawm blast furnaces thiab hluav taws xob rauv. Qhov ceev ntawm manganese yog 7.43g / cm³, lub melting point yog 1245 degree, thiab boiling point yog 2150 degree. Manganese muaj kev sib raug zoo nrog oxygen thiab tuaj yeem tsim manganese oxide ruaj khov nrog oxygen. Tsis tas li ntawd, manganese, raws li cov khoom siv ntxiv, tuaj yeem txhim kho hardness, plasticity, toughness thiab hnav tsis kam ntawm cov hlau, thiab yog siv dav hauv cov qauv hlau, cov cuab yeej steel, stainless hlau, steel hlau, tshav kub-resistant steel, hnav-resistant steel thiab lwm yam alloys. hlau.
