Metallurgical Product Description
Ferromanganese: Ib qho hlau alloy muaj li ntawm manganese thiab hlau. Cov pawg tseem ceeb: cov pa roj carbon ntau ferromanganese (muaj 7% carbon), nruab nrab carbon ferromanganese (muaj 1.0 ~ 1.5% carbon), qis carbon ferromanganese (muaj 0.5% carbon), metallic manganese, iav hlau, silicon-manganese alloy.

Ferromanganese moj tej tawg rauv smelting
Feem ntau, blast furnaces nrog qhov siab tsawg dua 1, 000m3 yog siv, thiab cov cuab yeej siv thiab cov txheej txheem ntau lawm yog ib yam li cov hlau ua cov tshuab tawg.
Thaum lub sij hawm tus txheej txheem ntawm manganese ore ntog los ntawm lub cub tawg saum toj kawg nkaus, cov nqi siab manganese oxides (MnO2, Mn2O3, Mn3O4) maj mam txo mus rau MnO los ntawm CO raws li qhov kub thiab txias. Txawm li cas los xij, MnO tsuas tuaj yeem raug txo ncaj qha rau hlau los ntawm cov pa roj carbon ntau, yog li smelting ferromanganese yuav tsum muaj qhov kub thiab txias dua. Vim li no, qhov cub tawg rau smelting ferromanganese siv cov coke ntau dua (kwv yees li 1600 kg / ton) thiab cua kub (1000 degree lossis siab dua). Txhawm rau txo qis manganese poob, lub slag yuav tsum tswj kom muaj alkalinity siab (CaO / SiO2 ntau dua 1.3). Vim tias qhov sib piv ntawm coke siab thiab qis qis qis qis, cov pa roj carbon monoxide thiab CO cov ntsiab lus ntawm ferromanganese-ua blast furnace yog siab dua li ntawm cov hlau ua lub tshuab hluav taws xob, thiab lub cub tawg kub kuj tseem siab dua (siab dua 350 degree) . Oxygen-enriched moj tej tawg tuaj yeem ua rau kom lub siab kub, txo qhov sib piv coke, nce cov zis, thiab txo qhov kub ntawm lub cub tawg vim qhov txo cov roj ntim, uas muaj kev txhim kho tseem ceeb ntawm ferromanganese smelting.
Ferromanganese hluav taws xob rauv smelting
Muaj ob hom kev txo smelting ntawm ferromanganese: txoj kev flux (tseem hu ua low manganese slag method) thiab flux-free method (high manganese slag method). Lub hauv paus ntsiab lus ntawm cov txheej txheem flux yog tib yam li cov blast furnace smelting, tshwj tsis yog tias hluav taws xob siv hluav taws xob siv coke rau cua sov. Los ntawm kev ntxiv cov txiv qaub, lub siab alkalinity slag (CaO / SiO2 yog 1.3 ~ 1.6) yog tsim los txo qhov poob ntawm manganese. Flux-free smelting yam tsis ntxiv cov txiv qaub ua rau cov hlau tsis muaj hlau, phosphorus thiab manganese-nplua nuj slag nrog qis alkalinity (CaO/SiO2 tsawg dua 1.{12}}) thiab cov ntsiab lus siab manganese. Txoj kev no muaj tsawg dua slag, uas tuaj yeem txo qis kev siv hluav taws xob, thiab qhov qis slag kub tuaj yeem txo cov evaporation poob ntawm manganese. Nyob rau tib lub sijhawm, cov khoom lag luam manganese-nplua nuj slag (muaj 25 ~ 40% manganese) tuaj yeem siv los ua cov khoom siv raw rau smelting manganese-silicon alloys, ua tiav cov txiaj ntsig siab dua. Kev rov qab zoo ntawm manganese (ntau dua 90%). Cov kev lag luam niaj hnub no feem ntau siv cov txheej txheem flux-dawb rau smelt carbon ferromanganese, thiab cov txheej txheem tsim khoom sib koom ua ke nrog cov smelting ntawm manganese-silicon alloy thiab nruab nrab thiab qis carbon ferromanganese yog qhia hauv daim duab.
