High Carbon Ferromanganese Chemical Composition Standard
Kev faib tawm ntawm feem ntau siv ferromanganese:
Muab faib ua:
Micro-carbonferromanganese: carbon tsis ntau tshaj 0.15%;
Tsawg carbon ferromanganese: carbon ntau dua {{0}}.15% mus rau 0.7%;
Nruab nrab carbon ferromanganese: carbon ntau dua {{0}}.7% mus rau 2.0%;
High carbon ferromanganese: carbon ntau dua 2.0% mus rau 8.0%; High carbon ferromanganese pa qib:
Cov ntsiab lus tseem ceeb ntawm FeMn68C7.0 yog: Mn:65-72 C: 2.0Si: 2.5P: 0.4S :{{10 }} 03. Cov ntsiab lus ntawm nruab nrab carbon ferromanganese yog: FeMn78C2.
Ferromanganese hauv steelmaking, siv los ua deoxidizer thiab alloy additive, yog qhov loj tshaj plaws ntawm cov hlau alloy. Cov manganese ore siv rau smelting ferromanganese feem ntau yuav tsum muaj 30 rau 40% manganese, qhov piv ntawm manganese rau hlau yog ntau dua 7, thiab qhov piv ntawm phosphorus rau manganese tsawg dua 0.003. Ua ntej smelting, manganese carbonate ore yuav tsum tau roasted ua ntej, thiab hmoov ore yuav tsum tau sintered los ua blocks. Ores nrog cov hlau siab thiab phosphorus cov ntsiab lus feem ntau tsuas yog siv ua ke, lossis los ntawm kev xaiv txo kom tsim cov hlau tsis tshua muaj thiab tsis muaj phosphorus manganese nplua nuj slag. Coke yog siv los ua tus neeg sawv cev txo qis hauv smelting, thiab qee cov nroj tsuag kuj siv cov thee lean lossis anthracite. Cov khoom siv raw khoom feem ntau yog txiv qaub, thiab silica feem ntau ntxiv thaum smelting manganese silicon alloy.
Ferromanganeseyog tsim los ntawm manganese ore. Nws yog melted nyob rau hauv lub cub tawg los yog hluav taws xob rauv. Txoj kev ntxov tshaj plaws ntawm kev tsim cov roj carbon ferromanganese tseem siv niaj hnub no. Ntxiv nrog rau kev tsim cov pa roj carbon ferro manganese siab, lub qhov cub tawg kuj tseem tsim cov iav hlau (Mn5% ~ 20%, C3.5% ~ 5.5%), silicon iav hlau (Mn15% ~ 20%, Si txog 10%) thiab Silvery Pig Hlau (Si txog 10%). Nws kuj kho hlau manganese ore los tsim manganese nplua nuj slag (artificial manganese nplua nuj ore).
