Cov nyhuv smelting ntawm nruab nrab carbon ferromanganese
Cov yam ntxwv ntawm nruab nrab carbon ferromanganese yog nws cov ntsiab lus qis carbon. Cov pa roj carbon ferromanganese nruab nrab tuaj yeem siv rau hauv ntau lub teb, tab sis nws tseem siv dav hauv kev lag luam steelmaking. Manganese yog cov khoom siv zoo dua siv hauv 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. Cov pa roj carbon ntsiab lus ntawm cov tshuaj tshwj xeeb nruab nrab carbon ferromanganese 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 siv dav siv deoxidizer thiab cov khoom siv hlau hauv steelmaking. Nws yog tsim los ntawm Manganese ore yog smelted los ntawm blast furnaces thiab hluav taws xob rauv. Qhov ceev ntawm manganese yog 7.43g / cm3, lub melting point yog 1245, C, thiab lub boiling point yog 2150. Manganese muaj ib tug muaj zog affinity nrog oxygen thiab muaj peev xwm tsim manganese oxide ruaj khov nrog oxygen. Tsis tas li ntawd, manganese Raws li cov khoom siv ntxiv, hlau tuaj yeem txhim kho hardness, plasticity, toughness thiab hnav tsis kam ntawm hlau. Nws yog dav siv hauv cov qauv hlau, cov cuab yeej hlau, cov hlau tsis muaj steel, cov hlau tsis muaj cua sov, hnav-resistant steel thiab lwm yam hlau alloy. Manganese kuj muaj
muaj peev xwm desulfurize thiab txo cov teeb meem ntawm leej faj. nyhuv.
Nruab nrab carbon ferromanganese Hauv kev lag luam steel, ferromanganese yog ib qho tseem ceeb deoxidizer thiab desulfurizer hauv kev lag luam steel. Cov hlau zoo yuav tsum tau deoxidized thiab desulfurized thaum lub sij hawm smelting txheej txheem, thiab kev siv deoxidizers yuav ua rau kom tus nqi ntau. Yog li, ferromanganese yog ib qho pheej yig deoxidizer. Desulfurization yog cais cov sulfur thiab lwm yam teeb meem hauv cov hlau kom ua tiav lub hom phiaj ntawm desulfurization ntawm ferromanganese, txo cov ntsiab lus ntawm cov teeb meem hauv cov hlau thiab txhim kho cov hlau zoo. Hauv kev lag luam steelmaking, kwv yees li {{0}} kg ntawm manganese tau noj rau txhua tuj ntawm cov hlau tsim. Raws li cov ntsiab lus carbon sib txawv, ferromanganese tuaj yeem muab faib ua peb pawg: nruab nrab carbon: carbon tsis tshaj 0.7%; nruab nrab carbon: carbon tsis tshaj 0.7% ~ 2.0%; siab carbon: carbon tsis tshaj 2.{{10}}%~8.0%. Cov pa roj carbon ferromanganese nruab nrab tuaj yeem muab faib ua cov pa roj carbon ferromanganese nruab nrab nrog cov ntsiab lus carbon tsawg dua 0.7% thiab cov khoom no nrog cov ntsiab lus carbon ntawm 0.7%-2.0%.
