Nruab nrab Carbon Ferromanganese
Medium carbon ferromanganese (MCFM) yog ib hom ferrous alloy uas muaj manganese thiab hlau ua ke nrog carbon. Nws yog dav siv rau kev tsim cov electrodes, tshwj xeeb tshaj yog E6013 electrodes hauv kev lag luam steel.
Khoom Taw Qhia
Medium carbon ferromanganese (MCFM) yog ib hom ferrous alloy uas muaj manganese thiab hlau ua ke nrog carbon. Nws yog dav siv rau kev tsim cov electrodes, tshwj xeeb tshaj yog E6013 electrodes hauv kev lag luam steel. Ntxiv nrog rau kev siv hauv kev lag luam steel, MCFM kuj tseem siv rau lwm qhov kev lag luam xws li kev lag luam foundry.
MCFM tuaj yeem tsim los ntawm ntau cov txheej txheem, suav nrog kev ua kom zoo-C Fe-Mn (high-C MCFM) lossis los ntawm cov txheej txheem silicothermic, uas siv silicon hauv Si-Mn alloy kom txo qis MnO ntxiv ntxiv li ore lossis slag. MCFM kuj tseem tuaj yeem tsim los ntawm cov txheej txheem carbon-carbon txo, uas cov pa roj carbon ntxiv rau hlau lossis lwm yam khoom siv ferromagnetic los tsim cov khoom siv ferromagnetic.
Cov ntsiab lus carbon ntawm MCFM tuaj yeem nyob ntawm 1 feem pua rau 1.5 feem pua , nrog cov ntsiab lus carbon ntawm 1 feem pua rau 1.5 feem pua yog feem ntau. Cov ntsiab lus ntawm manganese tuaj yeem nyob ntawm 75 feem pua rau 85 feem pua, nrog rau Mn cov ntsiab lus xws li 75 feem pua rau 85 feem pua. Cov ntsiab lus carbon thiab manganese ntawm MCFM tuaj yeem cuam tshuam rau nws cov khoom, ua rau nws haum rau ntau yam kev siv.
Hauv kev lag luam steel, MCFM yog siv los ua deoxidizer thiab alloying additive. MCFM nrog siab Fe-Mn cov ntsiab lus lossis MCFM nrog cov ntsiab lus C siab, uas yog tsim thaum lub sij hawm refining ntawm Fe-Mn nrog siab C ntsiab lus, yuav siv tau nyob rau hauv smelting txheej txheem los tsim MCFM electrodes. Qhov piv ntawm manganese rau Fe-Mn feem ntau ntau dua 7, thiab qhov piv ntawm phosphorus rau manganese tsawg dua 0.003.
Txhawm rau tsim MCFM electrodes, Fe-Mn ore yuav tsum tau roasted kom tshem tawm cov pa roj carbon, thiab tom qab ntawd cov hmoov ore yuav tsum tau sintered thiab agglomerated. Ores nrog cov ntsiab lus hlau thiab phosphorus siab tsuas yog siv los ua ke lossis los ntawm kev xaiv txo kom tau txais manganese-nplua nuj slag nrog tsawg hlau thiab phosphorus cov ntsiab lus. Hauv smelting, coke yog siv los ua tus neeg sawv cev txo qis, thiab qee lub mills kuj siv cov thee lean lossis anthracite ua cov khoom siv raw. Cov txiv qaub feem ntau yog ntxiv los ua cov khoom siv raw thaum lub sijhawm smelting, vim nws tuaj yeem pab kho pH thiab tshem tawm impurities los ntawm slag.
Ntxiv nrog rau kev siv hauv kev lag luam steel, MCFM kuj tseem siv rau lwm qhov kev lag luam xws li kev lag luam foundry. MCFM tuaj yeem siv los ua deoxidizer thiab alloying additive nyob rau hauv cov txheej txheem casting, uas tuaj yeem txhim kho cov khoom zoo xws li durability, machinability thiab formability.
