Lub hauv paus ntsiab lus ntawm silicon manganese alloy

Smelting silicon manganese alloy nyob rau hauv lub cub hluav taws xob yog tib yam li smelting carbon manganese hlau. Fe thiab P nyob rau hauv lub cub tawg nqi yog thawj zaug txo, thiab siab valent oxides ntawm Mn decompose nyob rau hauv lub sab sauv txheej los yog txo los ntawm CO mus rau tsawg valent oxide MnO. Qhov tsawg valent oxide MnO ces reacts nrog C los tsim carbides, thiab cov tshuaj tiv thaiv mis yog sau raws li nram no
MnO plus (1 plus x) C → MnCx plus CO
Raws li cov khoom siv hluav taws xob nkag mus rau hauv qhov chaw kub kub, cov tshuaj tiv thaiv ntawm C txo SiO2 pib tshwm sim.
SiO2 plus 2C=Si plus 2CO
Qhov txo Si reacts nrog cov generated MnCx los tsim ib tug silicon manganese alloy, uas txhawb nqa qhov txo ntawm Si. Cov tshuaj tiv thaiv mis yog
SiO2 plus 2C plus MnCx=Mn · Si · Cx plus 2CO
Qhov ntau Si yog generated, ntau dua cov carbides raug rhuav tshem, thiab qis dua cov ntsiab lus ntawm cov hlau alloy. Thaum cov ntsiab lus ntawm silicon ntawm cov hlau yog qis dua 23.5 feem pua ​​(xws li silicomanganese 10, silicomanganese 14, silicomanganese 17, thiab silicomanganese 20), cov tshuaj tiv thaiv ntawm silicon rhuav tshem carbides tuaj yeem sau tau.
(Mn, Fe) 7C3 plus 7Si=7 (Mn · Fe) Si plus 3C
Yog tias cov ntsiab lus ntawm silicon siab, cov tshuaj tiv thaiv uas rhuav tshem carbides tuaj yeem sau tau
(Mn, Fe) 7C3 plus 10Si=7 (Mn · Fe) Si plus 3SiC
