FERRO SiliconYog ib qho tseem ceeb tshaj plaws hauv steelmaking, casting, thiab metallurgy, nrog cov qib txhais tau los ntawm lawv cov ntsiab lus silicon. Ntawm cov feem ntau siv tau sivFerro Silicon 72thiabFERRO Silicon 75Cov. Thaum lawv cov npe sib txawv ntawm ob peb tus lej, cov qib kawm no muaj cov khoom sib txawv uas ua rau lawv muaj kev lag luam tshwj xeeb. Nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb los txhim kho kev ua haujlwm thiab tus nqi. Hauv qab no yog cov ncauj lus piav qhia ntxaws ntxaws los pab koj xaiv cov qib rau koj txoj haujlwm.
Silicon Cov ntsiab lus: Cov Tub Ntxhais Diffinter
Thawj qhov sib txawv ntawm lawv cov silicon (SI) kev xav tau, uas ncaj qha cuam tshuam lawv qhov kev ua tau zoo hauv cov txheej txheem kev lag luam:
Fesi 72: Muaj 70-73% silicon. Qhov qis dua cov ntsiab lus silicon txhais tau tias nws muaj hlau dua me ntsis hlau (feem ntau 25-28%) piv rau qib 75.
Fesi 75: Muaj 72-80% silicon (nrog cov khoom lag luam feem ntau ntawm 75%). Nws qhov kev pharyon siab dua puas txo cov ntsiab lus hlau rau ib puag ncig 20-25%.
Vim li cas nws tseem ceeb:Silicon yog lub caij ua haujlwm hauv Ferro silicon, lav rau deoxidation, kev siv ua alloy, thiab cov tshuab ua kom zoo nkauj thiab khaws cia. Cov ntsiab lus silicon ntau dua ua tau cov khoom siv no, ua rau Qib 75 ntau dua hauv cov txheej txheem uas xav tau cov deoxidation muaj zog lossis ua kom meej.
Tshuaj lom neeg siv tshuaj: impurities thiab kev ua tau zoo
Dhau silicon, kab kawm zoo li txhuas (al), calcium (ca), phosphorus (p) (c) (c) (c))) (c) (c) (c))
| Lub ntsiab | Ferro Silicon 72 | FERRO Silicon 75 | Cuam tshuam rau kev ua tau zoo |
|---|---|---|---|
| Aluminium (AL) | Tsawg dua los yog sib npaug rau 2.0% (qee zaum siab dua) | Tsawg dua los yog sib luag rau 1.5% (qis-}} Aluminium cov kawm muaj) | Tsawg aluminium txo cov kev txwv tsis pub tsis muaj kev txwv tsis pub muaj nyob rau hauv cov hlau, tseem ceeb rau high {| purity alloys. |
| Calcium (ca) | Tsawg dua los yog sib npaug rau 1.0% | Tsawg dua los yog sib npaug rau 0.8% | Cov tshuaj calcium ntau tuaj yeem ua rau tsis zoo; Qeb 75 yog qhov xav tau rau kev tsim cov hlau huv. |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.04% | Tsawg dua los yog sib npaug rau 0.03% | Tsawg dua phosphorus yog qhov tseem ceeb heev rau qis qis -} alloy alloy yuav tsum tau zam. |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.02% | Tsawg dua los yog sib npaug rau 0.015% | Txo cov leej faj ntau dua cov hlau lub weldability thiab corrosion tsis kam. |
Tus yam ntxwv:Hauv kev tsim tawm tsheb kauj vab, qhov chaw qis yog qhov yuav tsum tau ua, FERRO silicon 75% 's tigdfur tshaj sulfur thiab phosphorus ua rau nws xaiv zoo dua.
Cov Ntawv Thov: Cov qib twg haum koj cov kev xav tau?
Lawv cov khoom sib xyaw ua haujlwm ua 72 thiab 75 haum rau cov luag haujlwm txawv teb chaws:
72 # Ferro Silicon: Qhov zoo tagnrho rau cov ntawv thov uas raug nqi ua haujlwm ntau dua ultra - siab purity. Cov siv sib xws li suav nrog:
General steelmakaking raws li ib qho kev deoxidization thib ob.
CARTE hlau ntau lawm (piv txwv, hlau grey) los txhawb graphite tsim.
Foundry cov ntawv thov uas muaj Qib Silicon Qib sib npaug thiab tus nqi.
75 # ferro silicon: Nyiam rau high - kev ua tiav cov txheej txheem xav tau muaj zog deoxidation lossis meej alloying:
Kev tsim cov high - cov hlau zoo (piv txwv li cov hlau qauv
Tsim cov hluav taws xob hlau (silicon hlau), uas cov ntsiab lus siab silicon kom muaj cov khoom sib nqus.
Magnesium smelting (pidgeon txheej txheem) raws li lub siab - equestic txo tus neeg sawv cev.
Kev sib cais hauv cov hlau stainless los txhim kho corrosion tsis kam.
Tus nqi thiab muaj
Tus nqi: Ferrro silicon 75 feem ntau yog 5-10% kim dua qib 72 vim nws cov ntsiab lus silicon siab dua thiab cov txheej txheem stricter ntxiv. Txo cov nqi (tseem ceeb rau Silicon txo hauv Arc Furnaces) tseem ua si lub luag hauj lwm {{5} dua li hluav taws xob ntau dua, nce cov nuj nqis ntau dua.
Kev yuav tau: Ob qib kawm tau dav dav, nrog Tuam Tshoj, Russia, thiab South Africa yog cov neeg xa khoom loj. Txawm li cas los xij, Ferro Silicon 75 tej zaum yuav muaj kev siv hluav taws xob thaum lub sijhawm xav tau cov caij nyoog (piv txwv li cov khoom lag luam steel sib txawv), raws li nws cov khoom lag luam hlau.
