Taw qhia
Ferrosilicon (FeSi) yog ib qho ferroalloy feem ntau siv hauv steelmaking thiab foundries, thiab nws "sib xyaw" yog ib qho ntawm thawj yam uas cov neeg yuav khoom xyuas ua ntej muab qhov kev txiav txim. Cov neeg feem ntau xav tias ferrosilicon tsuas yog hais txog cov ntsiab lus ntawm silicon xwb, tab sis hauv kev lag luam tiag tiag thiab kev tsim khoom tiag tiag, cov khoom muaj xws li impurity txwv, qib qib, thiab qee zaum txawm tias qhov loj me - ntsig txog kev xav. Hauv qab no yog cov lus nug feem ntau cov neeg yuav khoom nug txog ferrosilicon muaj pes tsawg leeg.
Kev lag luam Q&A: Dab tsi yog qhov sib xyaw ntawm Ferrosilicon?
Q1: ferrosilicon yog dab tsi?
Ferrosilicon feem ntau yog ua los ntawmsilicon (Si)thiabhlau (Fe). Tus lej qib feem ntau qhia koj txog qib silicon-piv txwv li,FeSi 75feem ntau txhais tau hais tias nyob ib ncig ntawm 75% silicon, nrog rau qhov seem feem ntau yog hlau.
Dhau li Si thiab Fe, ferrosilicon kuj muaj me me ntawm lwm cov ntsiab lus. Cov no feem ntau hu ua impurities, tab sis lawv tseem tseem ceeb vim tias lawv tuaj yeem cuam tshuam cov hlau zoo thiab cov txheej txheem ruaj khov.
Q2: Dab tsi yog qhov sib xyaw ua ke rau cov qib xws li FeSi75, FeSi72, thiab FeSi65?
Cov qauv sib txawv thiab cov neeg muag khoom tuaj yeem sau npe sib txawv me ntsis, tab sis kev cia siab ntawm kev ua lag luam zoo li no:
FeSi 75: Si ib ncig74–76%, sib npaug feem ntau Fe
FeSi72: Si ib ncig72–73%, sib npaug feem ntau Fe
FeSi65: Si ib ncig65–68%(nyob ntawm tus qauv), sib npaug feem ntau Fe
Hauv kev yuav khoom, cov neeg yuav khoom feem ntau tsom xyuas seb cov ntsiab lus silicon puas yogruaj khovlos ntawm batch mus rau batch, tsis tsuas yog txawm nws hits ib tug xov tooj.
Q3: Dab tsi impurity ntsiab yog ib txwm teev nyob rau hauv ferrosilicon COA?
COA (Certificate of Analysis) feem ntau suav nrog:
Al (Aluminium)
C (Carbon)
P (phosphorus)
S (Sulfur)
Qee cov neeg siv khoom kuj nug txog cov ntsiab lus lossis kev txwv nruj dua nyob ntawm daim ntawv thov (piv txwv li, cov qib hlau huv yuav xav tau qis dua P thiab S). Txawm hais tias ob tus neeg muag khoom muag "FeSi75," qhov kev tswj tsis huv tuaj yeem sib txawv, thiab qhov ntawd tuaj yeem ua rau muaj txiaj ntsig sib txawv hauv steelmaking.
Q4: Vim li cas impurities tseem ceeb yog tias cov khoom yog Si thiab Fe?
Vim hais tias nyob rau hauv steelmaking, me me impurity hloov yuav ua rau pom kev tshwm sim -tshwj xeeb tshaj yog nyob rau hauv scale. Piv txwv li:
Siab duaPtej zaum yuav ua rau kom brittleness nyob rau hauv tej steels.
Siab duaStuaj yeem cuam tshuam ductility thiab nto zoo.
Altuaj yeem cuam tshuam rau hom kev suav nrog thiab kev coj noj coj ua.
Ctuaj yeem hloov cov hlau qhov kawg carbon tshuav nyiaj li cas.
Yog li thaum cov neeg yuav khoom nug txog "kev sib xyaw," lawv feem ntau txhais tau tias: "Puas yog silicon ruaj khov, thiab cov impurities puas tswj tau txaus rau kuv qib steel?"
Q5: Puas yog qhov loj me puas cuam tshuam rau kev sib xyaw, lossis nws puas yog qhov teeb meem cais?
Particle loj tsis hloov cov tshuaj muaj pes tsawg leeg nws tus kheej, tab sis nws tuaj yeem cuam tshuam cov khoom siv li cas - melting ceev, plua plav poob, thiab silicon rov qab. Tias yog vim li cas ntau tus neeg yuav khoom tshawb xyuas qhov sib xyaw thiab qhov loj me ua ke. Piv txwv li,zoo FeSiyuav yaj sai dua tab sis nws tuaj yeem tsim cov plua plav ntau dua yog tias tsis ua haujlwm zoo.
Yog li thaum qhov muaj pes tsawg leeg yog cov tshuaj lom neeg, qhov loj yog qhov ua tau zoo -ob qho tib si cuam tshuam cov txiaj ntsig kawg.
Hais txog peb cov khoom
Peb muab ferrosilicon rau cov qib sib xws xws liFeSi75, FeSi72, thiab FeSi65, nrog ruaj khov silicon cov ntsiab lus thiab tswj impurities. Yog tias koj qhia peb txog koj daim ntawv thov (steelmaking, foundry, hluav taws xob hlau, thiab lwm yam) thiab qhov loj me, peb tuaj yeem qhia COAs tsis ntev los no thiab pab koj xaiv cov qib uas haum rau koj cov txheej txheem, nrog rau cov nqi FOB tam sim no thiab cov kev xaiv ntim khoom.
