Yuav Ua Li Cas Xaiv Cov Khoom Zoo Ferrosilicon 75?
Tshawb xyuas Qhov Zoo Ntawm Sife 75 Los Ntawm Cov Khoom Raw
Silica yog cov khoom siv tseem ceeb rau kev tsim cov ferrosilicon 75, yog li qhov zoo ntawm silica kuj txiav txim siab qhov zoo ntawm ferrosilicon 75, ces yuav ua li cas txiav txim qhov zoo ntawm silica? Qhov yuav tsum tau muaj yog tias cov ntsiab lus ntawm silicon hauv silica yuav tsum muaj ntau dua 97%, thiab thaum lub sij hawm smelting ntawm silica, ib hom ntawm txhuas oxide feem ntau yuav tsim. Cov khoom no yuav tsis tsuas cuam tshuam cov teeb meem slag tawm hauv steelmaking, tab sis kuj ua rau cov txhuas hauv ferrosilicon txhim kho, cuam tshuam rau qhov zoo ntawm ferrosilicon.
Cov ntsiab lus ntawm Calcium Oxide thiab Magnesium Oxide cuam tshuam qhov zoo ntawm Ferrosilicon 75
Feem ntau, cov ntsiab lus ntawm calcium oxide thiab magnesium oxide hauv ferrosilicon yuav tsum tsawg dua 1%. Yog tias cov ntsiab lus loj dua li qhov ntau, qhov ntau ntawm smelting slag yuav nce ntxiv thaum siv cov hlau ua, thiab kev yaig ntawm lub qhov ncauj hlau yuav cuam tshuam rau qhov zoo ntawm ferrosilicon 75.
Lub Granularity ntawm Silica kuj cuam tshuam rau qhov zoo ntawm Ferrosilicon 75
Qhov loj ntawm silica kuj yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm ferrosilicon 75. Yog tias qhov loj ntawm silica loj dhau, cov tshuaj tiv thaiv ceev yuav qeeb thaum lub sij hawm smelting, tab sis yog tias qhov loj me dhau lawm, ntau cov hmoov yuav cuam tshuam rau permeability ntawm ferrosilicon 75 nto. Yog li pes tsawg particle loj yog tsim nyog? Kuv t yuav tsum tau hais tias cov silica particle loj siv rau zus tau tej cov ferrosilicon 75 yuav tsum yog 60 ~ 120mm, ntawm uas ntau tshaj 80mm yuav tsum ntau tshaj 50%.
Qhov txawv ntawm Silicon Carbon Alloy thiab Ferrosilicon yog dab tsi?
Silicon-carbon alloy yog hom tshiab ntawm ferroalloy. Silicon-carbon alloy yog pheej yig dua ferrosilicon. Thaum muas tib hom ferrosilicon, silicon -carbon alloy feem ntau yuav 2/5 pheej yig dua. Yog li ntawd, thaum tus nqi ntawm ferrosilicon nce qis dua silicon-carbon alloy yog ib qho kev xaiv zoo dua rau cov tuam ntxhab kom txuag nqi.
Vim tias tus nqi ntawm silicon- carbon alloy yog pheej yig dua li ntawm ferrosilicon, cov ntsiab lus ntawm silicon- carbon alloy yuav qis dua li ntawm ferrosilicon. Txawm li cas los xij, qhov txo qis yog me me thiab nws tuaj yeem siv los hloov ferrosilicon. Nqe kom zoo dua, silicon carbon alloy yog qhov kev xaiv zoo dua.
Silicon-carbon alloy tuaj yeem siv los hloov ferrosilicon, tab sis tseem yuav muaj qhov sib txawv ntawm kev siv. Vim hais tias silicon - carbon alloy muaj ib tug me ntsis qis tshaj li ferrosilicon thiab silicon, nws muaj zoo deoxidation thiab slag tshem tawm tshaj ferrosilicon. Nws yog qhov qis dua, tab sis tsis cuam tshuam rau kev siv ib txwm.
