Ferrosilicon Manganese Alloy Smelting Kub

Ferrosilicon manganese alloysmelting kub: "850-1300 degree .

Nyob rau hauv tus txheej txheem ntawm smelting thiab cua sov ntawm tus nqi, cov nqi siab oxides ntawm manganese thiab hlau nyob rau hauv tus nqi yog decomposed nyob rau hauv lub kub kub cheeb tsam ntawm lub charger cheeb tsam los yog carbon monoxide raug txo kom tsawg-qis oxides, mus rau {{2} }K, tus nqi siab manganese oxide maj mam txo qis rau MnO, thiab tag nrho FeO raug txo qis ntxiv rau Fe.

Mno yog qhov ruaj khov thiab tuaj yeem txo ncaj qha nrog cov pa roj carbon. Vim tias SiO2 siab nyob rau hauv tus nqi, MnO tsis muaj sij hawm los txo thiab hnov ​​​​mob nrog nws los tsim cov manganese silicate tsawg.

Yog li, qhov txo qis ntawm MnO yog ua tiav hauv manganese silicate los ntawm cov kua slag. "

Smelting txoj cai ntawm manganese silicon alloy

Nyob rau hauv cov txheej txheem smelting ntawm tus nqi, tus nqi siab oxides ntawm manganese thiab hlau nyob rau hauv tus nqi yog decomposed nyob rau hauv high kub los yog txo kom tsawg-qhib oxides los ntawm CO nyob rau hauv tus nqi cheeb tsam, mus rau 1373 ~ 1473K, high-qib manganese oxide. yog maj mam txo mus rau MnO, thiab tag nrhoFeOyog ntxiv txo rau Fe; MnO yog qhov ruaj khov thiab tuaj yeem txo ncaj qha nrog cov pa roj carbon. Vim tias SiO2 siab nyob rau hauv tus nqi, MnO tsis muaj sij hawm los txo thiab hnov ​​​​mob nrog nws los tsim cov manganese silicate qis. Yog li, qhov txo qis ntawm MnO yog ua tiav hauv manganese silicate ntawm kua slag. Lub xeev thiab melting point ntawm manganese silicate yog: MnO + SiO2=MnSiO3 t melting =1250 degree 2MnO+ SiO2=Mn2SiO4 t melting =1345 degree Vim manganese thiab carbon tuaj yeem ruaj khov. compound Mn3C, manganese carbide Mn3C yog tau los ntawm kev txo qis ntawm carbon.
