2. Cov Txheej Txheem Thoob Ntiaj Teb (ISO 5445)
Cov qauv thoob ntiaj teb tau qhia raws li"Ntau ntawm Fesi + cov ntsiab lus silicon",Piv txwv li, Fesi75 sib raug rau cov ntsiab lus silicon ntawm 72% rau 80%.
Qib Silicon (Si) /% Aluminium (Al) /% Carbon (C) /% Raug Siv
Fesi {90 87 ~ 95 tsawg dua los yog sib npaug rau 1.5 tsawg dua lossis sib npaug nrog 0.1 daim ntawv thov rau siab huv
Fesi 75 72 ~ 80 tsawg dua lossis sib npaug nrog 1.5 tsawg dua lossis sib npaug nrog 0.2 steel ntau lawm, hlau loj
Fesi 65 65 ~ 72 tsawg dua lossis sib npaug rau 2.0 tsawg dua lossis sib npaug ntawm 0.2 dav dav hlau me me, khoom siv
Fesi 45 40 ~ 47 tsawg dua los yog sib npaug rau 2.0 tsawg dua lossis sib npaug nrog 0.3 cov ntawv thov tsawg
3. American tus qauv (ASTM A100)
Cov neeg Asmeskas cov txheej txheem siv ib txoj kev zoo sib xws, tab sis qhov yuav tsum muaj rau kev tsis txaus siab ntau:
Silicon (si) /% aluminium (al) /% carbon (c) /% raug thov
Fesi 75 74 ~ 80 tsawg dua los yog sib npaug ntawm 1.0 tsawg dua lossis sib npaug ntawm 0.15 High-Tech Metallurgy, Alloy Steel
Fesi 65 63 ~ 68 tsawg dua lossis sib npaug rau 2.0 tsawg dua lossis sib npaug nrog 0.2 tag nrho cov deoxidation, cam khwb cia hlau
Fesi 50 47 ~ 52 tsawg dua lossis sib npaug nrog 2.0 tsawg dua lossis sib npaug, cov ntawv thov tsawg
4. European Txuj Ci (Rau 13835)
Lub European txheem tsom rau cov ntsiab lus silicon raws li qhov taw qhia tseem ceeb thiab qhia txog ib puag ncig cov kev xav tau:
Qib Silicon (Si) /% Aluminium (al) /% carbon (c) /% ib puag ncig ib puag ncig
Fesi 75 72 ~ 80 tsawg dua lossis sib npaug nrog 1.5 tsawg dua lossis sib npaug rau 0.2 dav dav (qis paug)
Fesi 65 65 ~ 72 tsawg dua los yog sib npaug rau 2.0 tsawg dua lossis sib npaug nrog 0.2 Kev Lag Luam
Fesi {45 40 ~ 47 tsawg dua lossis sib npaug rau 2.5 tsawg dua lossis sib npaug rau 0.3 yig
5. Cov nyiaj muas tshwj xeeb
Muaj cov hom tshwj xeeb tshwj xeeb rau cov kev xav tau tshwj xeeb:
Tsawg - al fesi75: Txhuas cov ntsiab lus tsawg dua los yog sib npaug rau 0.5%, siv rau kev txo qis ntawm cov hlau magnesium (kom tsis txhob cuam tshuam ntawm txhuas ntawm cov tshuaj tsw qab ntawm magnesium.
Muaj Siab Dawb Ferrosilicon (Fesi90): Silicon cov ntsiab lus ntau dua los yog sib npaug rau 87%, siv cov hlau hluav taws xob tsawg, hlau steel, hlau stainless thiab lwm cov hlau tshwj xeeb.
Ferrosilicon rau foundry: 1% -3% aluminium, txhawb nqa graphitization ntawm cam khwb cia hlau (piv txwv li cov hlau du sab).
6. Cov ntsiab lus tseem ceeb thaum xaiv hom
Silicon Cov Ntsiab Lus:
High silicon (Fesi75-90): steel deoxidation, alloying, magnesium ntau lawm.
Nruab nrab -} qis silicon (Fesi 45-65): Foundry, Dav Hlau.
Cov Kws Koom Tes Tswj:
Steelmaking yuav tsum muaj tsawg aluminium thiab cov ntsiab lus carbon thiab foundry tuaj yeem txo cov ntsiab lus txhuas.
Tus nqi yam:
Cov qib siab muaj ntau dua thiab cov nqi ua tau zoo dua thiab cov txiaj ntsig zoo yuav tsum tau ntsuas nyob ntawm daim ntawv thov.
