Taw qhia
Ferrosilicon (FeSi) yog ib qho ntawm cov khoom siv alloying ntau tshaj plaws hauv kev tsim steel thiab casting, tab sis ntau tus neeg yuav khoom -tshwj xeeb yog cov tshiab- feem ntau tsis paub meej txog lub ntsiab lus ntawm FeSi qib xws li 75, 72, 65, thiab lwm yam. Cov lej no yuav zoo li yooj yim, tab sis lawv sawv cev rau qhov sib txawv ntawm kev ua tau zoo, impurities, thiab kev thov kom haum.
Hauv qab no yog ob peb nqe lus nug uas cov neeg yuav khoom txawv teb chaws feem ntau nug thaum sim nkag siab tias qib ferrosilicon raug cais li cas thiab txhua tus siv li cas hauv kev lag luam.
Kev lag luam Q&A: Cov Qib ntawm Ferrosilicon yog dab tsi?
Q1: Cov lej hauv FeSi qib txhais tau li cas?
Tus lej qib sawv cev rauyam tsawg kawg nkaus ntawm siliconnyob rau hauv lub alloy.
Piv txwv li:
FeSi75 → txog 75% silicon
FeSi72 → txog 72% silicon
FeSi65 → txog 65% silicon
Cov ntsiab lus silicon siab dua feem ntau ua rau muaj peev xwm deoxidizing muaj zog thiab ruaj khov alloying kev ua tau zoo. Cov qib no muaj nyob vim tias cov khoom siv hlau sib txawv xav tau cov qib silicon sib txawv thiab cov qauv nqi.
Q2: Cov qib twg FeSi feem ntau siv hauv steelmaking?
Cov qib siv dav tshaj plaws yog:
FeSi 75- kev ua haujlwm siab, nyiam dua - steels zoo
FeSi72- Kev lag luam thiab tsim nyog rau kev ua steel hlau
FeSi65- tus nqi - kev xaiv zoo rau cov ntawv siv hlau thiab cov khoom tsim
Ntawm cov no,FeSi 75yog qhov nrov tshaj plaws thoob ntiaj teb vim nws qhov zoo sib xws silicon rov qab thiab qis impurity ntau. FeSi72 ua raws li ze vim tias nws muaj kev ua tau zoo sib xws ntawm tus nqi qis, ua rau nws txaus nyiam rau cov mills ua cov qauv carbon steel.
Q3: Puas muaj lwm qib FeSi ntxiv rau 75, 72, thiab 65?
Yog lawm. Qee thaj chaw siv cov kev faib tawm ntxiv xws li:
FeSi 90(siab-silicon alloy, tsawg dua)
FeSi45(tsawg-silicon alloy rau kev siv tshwj xeeb)
FeSiMg(magnesium-muaj ferrosilicon rau nodular cam khwb cia hlau)
Atomized FeSilos yogMilled FeSi( cais los ntawm cov duab particle es tsis yog cov ntsiab lus silicon)
Thaum FeSi75 thiab FeSi72 yog tus thawj coj thoob ntiaj teb kev lag luam, cov qib tshwj xeeb no ua haujlwm rau cov ntawv thov tshwj xeeb xws li casting, magnesium kho, thiab hmoov metallurgy.
Q4: Cov qib FeSi txawv li cas cuam tshuam cov hlau zoo?
Qib xaiv cuam tshuam rau ntau yam ntawm steelmaking:
Deoxidation efficiency- qib siab dua tshem cov pa oxygen zoo dua
Silicon rov qab- qib siab dua tau txais txiaj ntsig zoo dua
Tswj impurity- Cov qib siab dua feem ntau muaj qis dua thiab zoo ib yam impurities
Alloy kev ua tau zoo- FeSi75 txhawb nqa cov qauv nplej zoo dua hauv qib siab - qib steel
Cov qib qis tseem tuaj yeem siv tau zoo, tab sis lawv yuav xav tau cov ntim ntxiv loj dua lossis ua rau muaj qhov sib txawv ntawm cov hlau ntau dua.
Xaiv cov qib zoo yog nyob ntawm hom hlau, qhov cub txoj kev, thiab cov nqi phiaj.
Q5: Yuav ua li cas cov neeg yuav khoom xaiv cov qib FeSi zoo tshaj plaws?
Cov neeg yuav khoom feem ntau pib lawv txoj kev xaiv ntawm peb yam:
Steel qib yuav tsum tau
Siab - zog los yog huv si - steel ntau lawm yuav tsum tau FeSi75.
Kev xav txog tus nqi
FeSi72 thiab FeSi65 pab txo tus nqi yam tsis muaj kev ua haujlwm loj rau cov hlau dav dav.
Impurity rhiab heev
Yog tias phosphorus, sulfur, lossis aluminium qib yuav tsum tau tswj nruj me ntsis, FeSi75 muaj kev nyab xeeb dua.
Ntau lub chaw tsim khoom tau sib xyaw cov qib- siv FeSi75 rau siab dua - cov khoom kawg thiab FeSi72 rau cov hlau zoo tib yam - kom sib npaug kev ua tau zoo thiab tus nqi.
Hais txog peb cov khoom
Peb muab ntau yam ntawm ferrosilicon qib, suav nrogFeSi75, FeSi72, thiab FeSi65, nyob rau hauv ntau yam particle loj haum rau ntau hom rauv. Ntau tus neeg muas zaub sib piv cov qhab nia raws li lawv cov kev xav tau ntau lawm, thiab peb tuaj yeem pab muab cov nqi FOB tshiab, COAs, thiab kev pom zoo xaiv qhov loj me. Yog tias koj tab tom tshawb nrhiav FeSi qib twg haum rau koj cov txheej txheem zoo tshaj plaws, tiv tauj peb -peb ib txwm npaj los txhawb koj txoj kev npaj yuav.
