Ferrosiliconyog qhov feem ntau siv thiab siv ferroalloy nyob rau hauv cov hlau thiab foundry industries. Fesi nrog cov ntsiab lus silicon ntawm 70-75% yog qhov kev xaiv tseem ceeb hauv kev lag luam vim nws qhov zoo tagnrho silicon-rau-hlau piv, muaj peev xwm deoxidizing zoo, thiab ruaj khov alloying nyhuv.

AON METALS tsim 70-75% ferrosilicon siv siab- zoo quartz, coke, thiab steel seem li raw cov ntaub ntawv, los ntawm high-kub txo smelting nyob rau hauv ib tug hluav taws xob arc rauv. Peb nruj me ntsis ua raws li lub teb chaws thiab thoob ntiaj teb cov qauv thiab muab cov khoom sib txawv ntawm txhuas thiab calcium cov ntsiab lus tswj thiab ntau qhov ntau thiab tsawg rau kev siv sib txawv.

Core Components thiab Functions:

Silicon (Si) 70-75%:Lub cev muaj zog deoxidizing uas txhim kho lub zog, hardness, thiab elastic txwv ntawm cov hlau; txhawb graphitization hauv cam khwb cia hlau.

Hlau (Fe):Cov khoom siv matrix uas ua kom muaj qhov sib npaug ntawm cov alloy thiab ua kom yooj yim ntxiv thiab yaj.

Aluminium (Al) thiab calcium (Ca):auxiliary deoxidizing cov ntsiab lus, thiab lawv cov ntsiab lus yuav tsum tau tswj kom meej raws li daim ntawv thov downstream (piv txwv li, qib qis aluminium yog siv rau hauv siab-cov hlau zoo los tiv thaiv Al₂O₃ suav nrog).

Daim ntawv thov teb

Steelmaking kev lag luam

Deoxidizer

Nws yog ib qho ntawm feem ntau sivcov deoxidizersnyob rau hauv cov txheej txheem steelmaking. Cov pa oxygen hauv cov hlau molten tuaj yeem ua rau muaj qhov tsis xws li qhov pores thiab slag inclusions hauv steel. Cov silicon hauv ferrosilicon muaj kev sib raug zoo nrog cov pa oxygen, uas tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten thiab txhim kho cov purity ntawm hlau.

Alloying tus neeg sawv cev

Silicon yog qhov tseem ceeballoying keebhauv steel. Ntxiv ferrosilicon tuaj yeem txhim kho lub zog, hardness, elastic txwv, hnav tsis kam thiab kub tsis kam ntawm cov hlau. Nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau tshwj xeeb xws li lub caij nplooj ntoos hlav steel thiab tshav kub-cov hlau tsis muaj zog. Piv txwv li, ntxiv qhov tsim nyog ntawm ferrosilicon rau lub caij nplooj ntoos hlav steel tuaj yeem txhim kho nws txoj kev txwv elastic thiab qaug zog.

Casting kev lag luam

Inoculant

Nws tuaj yeem siv los ua ib qho inoculant nyob rau hauv cov txheej txheem casting los txhawb graphitization, txo qhov nyiam ntawm cov hlau cam khwb cia hlau, thiab ua cov graphite nplej ntawm cov castings refined thiab sib npaug, yog li txhim kho cov khoom siv ntawm cov castings, xws li lub zog, toughness thiab ductility. Nws yog dav siv nyob rau hauv zus tau tej cov grey cam khwb cia hlau thiab ductile hlau.

Nodularizer auxiliary tus neeg sawv cev

Hauv kev tsim cov hlau nplaum, qee zaum nws tuaj yeem siv los ua ib qho kev pabcuam ntxiv ntawm spheroidizer. Thaum siv ua ke nrog cov spheroidizer, nws yuav pab kom ruaj khov cov nyhuv spheroidizing, txhim kho cov morphology thiab faib cov graphite npas, thiab txhim kho qhov zoo ntawm cov hlau ductile.

FAQ

Q1: Vim li cas thiaj muaj cov qib sib txawv (A thiab B) rau tib lub npe 75% ferrosilicon?

A1:Cov -A thiab -B hauv koj lub rooj feem ntau yog sawv cev rau ntau theem ntawm kev tswj tsis huv thiab kev tso npe thov:

- Qib A (piv txwv li,FeSi 75Al0.5-A):Feem ntau hais txog cov impurities qis dua (tshwj xeeb tshaj yog txhuas, carbon, phosphorus, thiab sulfur) thiab cov ntsiab lus ntawm silicon nqaim (piv txwv li, 74-80%). Haum rau high-quality steels tshwj xeeb thiab tseem ceeb castings uas yuav tsum tau zoo.

- qib B (eg, FeSi75-B):Kev tswj impurity yog qhov yooj yim, nrog cov ntsiab lus ntawm silicon dav dua (72-80%). Haum rau cov pa roj carbon steel thiab castings, muab cov nqi zoo dua.

Qhov kev xaiv yuav tsum yog raws li qhov kawg ntawm kev siv koj cov khoom thiab kev tswj hwm tus nqi.

Q2: Vim li cas cov ntsiab lus txhuas hauv ferrosilicon tswj tau? Dab tsi yog qhov tsis zoo ntawm cov ntsiab lus aluminium siab?

A2: Aluminum is a strong deoxidizer, but excessively high aluminum content (>1.5%) tuaj yeem ua rau ob qho teeb meem:

Kev tsim cov nkig Al₂O₃ suav nrog: Cov Al₂O₃ tsim thaum lub sij hawm txhuas deoxidation yog cov khoom, muaj cov ntsiab lus siab melting, thiab cov ntaub ntawv pawg. Nws yog qhov nyuaj rau ntab, txo qhov qaug zog lub neej thiab qhov zoo ntawm cov hlau.

Clogging ntawm lub nozzle: Al₂O₃ yooj yim accumulates nyob rau hauv lub puab phab ntsa ntawm lub nruam casting submersible nozzle, ua rau lub nozzle blockage thiab cuam tshuam cov smoothness.

Yog li ntawd, rau siab - steels zoo (xws li automotive steel thiab pipeline steel),qis-aluminium ferrosilicon(Al Tsawg dua lossis sib npaug li 0.5%) feem ntau yuav tsum tau.

Q3: Yuav ua li cas txiav txim qhov zoo ntawm ferrosilicon?

A3: Kev txiav txim ua ntej tuaj yeem ua los ntawm cov hauv qab no:

Cov tsos mob: High- zoo ferrosilicon yog ci grey, nrog ib tug hlau luster ntawm tus ntoo khaub lig-section, thiab dawb los ntawm hnyav non{2}}hlau inclusions thiab xeb.

Loj: Xyuas seb cov hmoov piv puas siab dhau thiab seb cov khoom puas zoo ib yam.

Kev Sau: Thov cov ntaub ntawv pov thawj rau txhua pawg thiab xyuas kom meej tias cov ntsiab lus tseem ceeb (Si, Al, Ca, C, P, S) ua tau raws li cov qauv.

Kev Siv: Raws li tib qho nyiaj ntxiv, saib xyuas cov nyhuv deoxidation (piv txwv li, lub calmness ntawm molten steel) thiab seb cov khoom muaj pes tsawg leeg yog ruaj khov.
