Ferro-silico-manganese
Ferromanganese silicon yog cov tshuaj lom neeg hlau. Nyob rau hauv cov txheej txheem smelting, ferromanganese silicon emits ib tug loj npaum li cas ntawm kub kub hmoov av uas muaj roj. Cov khoom tseem ceeb ntawm cov hmoov av yog MnO thiab SiO2, thiab qhov loj me ntawm cov hmoov av feem ntau tsawg dua 5um. Cov pa roj av uas muaj plua plav zoo li no muaj qhov loj me me yog qhov ua rau muaj kev phom sij rau sab hauv tsev thiab sab nraum zoov thiab tib neeg kev noj qab haus huv. Nws tseem cuam tshuam rau huab cua ib puag ncig ntawm ferroalloy thiab kev noj qab haus huv ntawm lub cev thiab lub hlwb ntawm cov neeg ua haujlwm.
Ferromanganese silicon yog ib hom manganese silicon alloy, uas muaj li 20% silicon thiab ntau tshaj 60% manganese. Raws li YB67-65, feem ntau raws li cov ntsiab lus sib txawv ntawm cov pa roj carbon monoxide thiab manganese silicon 23, manganese silicon 20, manganese silicon 17, manganese silicon 14, manganese silicon 12 thiab lwm qib rau qib, yog cov khoom siv deoxidizer siv hauv steelmaking. Thaum nws yog siv los deoxidize, cov silicate suav nrog uas tsim muaj qhov qis qis dua li manganese oxide thiab silicon oxide, thiab yooj yim los sib sau ua ke thiab ntab, yog li cov khoom tsis yog xim hlau suav nrog hauv cov hlau tsawg dua.
Ferromanganese silicon yog ib qho alloy ntawm silicon, manganese thiab hlau tau los ntawm kev txo qis ntawm silicon ore thiab manganese ore. Cov ntsiab lus ntawm silicon ferromanganese yog 10% mus rau 37%, manganese cov ntsiab lus yog 57% mus rau 80%, thiab cov hlau muaj nyob hauv silicon ferromanganese yog qhov sib txawv.
Bulk ferromanganese silicon yog lub teeb grey alloy uas nws cov xim hlau ua kom muaj zog nrog kev nce ntawm silicon muaj pes tsawg leeg. Ferromanganese silicon yog tawg mus rau hauv chunks tom qab nchuav, thiab chunks ntawm ferromanganese silicon tuaj yeem ua npua hlau chunks (loj ingots) los yog me me ingots. Ferromanganese silicon tom qab crushing, sib tsoo thiab tshuaj ntsuam, yuav muaj ntau theem ntawm particle loj. Qhov loj me (thaiv qhov loj) yog txiav txim siab los ntawm kev sib tsoo ntawm ferrosilico-manganese los ntawm square mesh cov ntxaij vab tshaus ntawm cov qauv sib txawv.
