1, Main faib
Silicon manganese muaj ntau nyob rau sab qab teb sab hnub poob ntawm Tuam Tshoj.
2, Lub hom phiaj tseem ceeb
Silicon manganese alloy feem ntau yog siv los ua cov khoom nruab nrab rau deoxidizer thiab alloying tus neeg sawv cev hauv kev tsim cov hlau, thiab tseem yog cov khoom siv tseem ceeb rau nruab nrab thiab qis carbon ferromanganese ntau lawm. Silicon manganese alloy yog ib qho alloy uas muaj manganese, silicon, hlau, thiab ib qho me me ntawm carbon thiab lwm yam khoom. Nws yog ib qho siv dav thiab muaj txiaj ntsig zoo ferroalloy. Nws qhov kev siv yog nyob qib thib ob ntawm cov khoom siv hluav taws xob ferroalloy. Cov silicon thiab manganese nyob rau hauv silicon manganese alloy muaj ib tug muaj zog affinity rau oxygen. Thaum silicon manganese alloy yog siv nyob rau hauv steelmaking, cov deoxygenation cov khoom MnSiO3 thiab MnSiO4 ua yog melted ntawm 1270 degree thiab 1327 degree, feem. Lawv muaj qhov zoo ntawm qhov tsis tshua muaj melting point, cov khoom loj, yooj yim ntab, thiab cov nyhuv deoxygenation zoo. Raws li cov xwm txheej zoo ib yam, siv manganese lossis silicon ib leeg rau deoxidation ua rau qhov kub hnyiab ntawm 46% thiab 37%, feem, thaum siv silicon manganese alloy rau deoxidation ua rau qhov kub poob ntawm 29% rau ob qho tib si. Yog li ntawd, nws tau dav siv nyob rau hauv steelmaking, nrog ib tug ntau lawm tus nqi siab tshaj qhov nruab nrab txoj kev loj hlob ntawm ferroalloys, thiab tau los ua ib tug indispensable composite deoxidizer thiab alloy additive nyob rau hauv lub steel kev lag luam.
Silicon manganese alloys nrog cov ntsiab lus carbon qis dua 1.9% tseem siv los ua cov khoom ua tiav rau kev tsim cov khoom nruab nrab mus rau qis carbon ferromanganese thiab electro silicothermic manganese hlau. Hauv kev lag luam ferroalloy ntau lawm, silicon manganese alloy siv rau steelmaking feem ntau yog hu ua lag luam silicon manganese alloy, silicon manganese alloy siv rau smelting low-carbon hlau yog hu ua tus kheej siv silicon manganese alloy, thiab silicon manganese alloy siv rau. smelting hlau yog hu ua siab silicon silicon silicon manganese alloy. Manganese tuaj yeem ua ke nrog silicon los ua ke silicides MnSiO3, MnSiO, thiab MnSiO3. Los ntawm daim duab silicon manganese lub xeev, nws tuaj yeem pom tias qhov ruaj khov max silicide yog MnSi. Vim tias qhov tsis zoo ntawm lub zog dawb tsim los ntawm silicides ntawm manganese, uas yog ntau dua li qhov tsis zoo ntawm lub zog dawb uas tsim los ntawm carbides ntawm manganese, qhov siab dua cov ntsiab lus ntawm silicon manganese alloys, cov ntsiab lus carbon tsawg dua.
