Daim Ntawv Thov Khoom

Steelmaking kev lag luam

Deoxidizer:

Nws yog ib qho ntawm cov nquag sivDeagidizersHauv cov txheej txheem statmaking. Txij li thaum oxygen nyob rau hauv Molten Steel tuaj yeem ua rau tsis xws luag xws li pores Piv txwv li, nyob rau tom qab theem ntawm converter statmaking, ntxiv 72 # Fesi rau cov neeg deascen rau deoxidation tuaj yeem txo cov txiaj ntsig oxygen tuaj yeem ua rau qib tsim nyog.

Alloying Tus Neeg Sawv Cev:

Silicon yog ib qho tseem ceebsib ntxaws alloyHauv hlau. Ntxiv 72% Ferrro Silicon Alloy tuaj yeem txhim kho lub zog, hardness, kev txwv ywj thiab ua kom kub ua hauj lwm zoo ntawm cov hlau. Ferrosilicon72 Ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau tshwj xeeb xws li lub caij nplooj ntoo hlav steel thiab cua sov- tiv taus hlau. Piv txwv li, ntxiv cov nyiaj uas tsim nyog rau cua sov tuaj yeem txhim kho nws cov khoom muaj zog thiab qaug zog ntau dua thiab ua kom muaj kev cuam tshuam ntau dua.

Nrhiav Kev Lag Luam Kev Lag Luam

Inoculant:

Hauv cov txheej txheem casting, nws tuaj yeem siv ua ib qho inoculant. Nws tuaj yeem txhawb cov duab graphitization, txo qhov nyiam ntawm cov hlau dawb, ua kom muab cov pob zeb ua kom yooj yim, yog li muab cov khoom siv me me ntawm cov khoom siv tshuab, xws li lub zog, kev nruj thiab ductility. Nws yog dav siv nyob rau hauv kev tsim cov grey cam khwb cia hlau thiab coorile hlau. Piv txwv li, hauv kev tsim cov hlau xeb, ntxiv 72 #

Nodularizer auxiliary tus neeg saib xyuas:

Hauv kev tsim cov hlau, nws tuaj yeem siv los ua ib qho kev sib ntxiv ntawm spheroidizer. Thaum siv ua ke nrog spheroidizer, nws pab tswj cov nyhuv sib xyaw, txhim kho cov pob morphology, txhim kho cov pob zeb thiab hluav taws xob graphite, thiab txhim kho qhov zoo ntawm cov hlau ua kom zoo. Piv txwv li, hauv qee cov txheej txheem sib txawv, cov spheroidizers tau ntxiv rau spheroidation, thiab tom qab ntawd 722ferrosization ntau ruaj khov thiab txo cov tsis xws luag xws li spheroidous neeg pluag.

Yuav ua li cas xaiv txoj cai ferrosilicon 72 khoom rau koj cov kev xav tau?

1. Txheeb xyuas cov qauv tseem ceeb

Silicon Cov Ntsiab Lus:

Cov ntsiab lus tseem ceeb ntawm Ferrosilicon 72 yog cov ntsiab lus silicon (72% -75%), thiab qhov raug txiav txim siab yuav tsum tau txiav txim siab raws li kev siv. Piv txwv li, yog tias nruj me ntsis kev tswj hwm deagmakation, cov khoom lag luam nrog lub silicon me ntsis cov ntsiab lus hloov pauv (piv txwv li, 73% yuav tsum tau xaiv; Rau cam khwb cia hlau inoculants, ib tug wider concuplitriation muaj peev xwm tuaj yeem ua kom zoo.

Impurity Elements:

Tsom rau cov ntsiab lus ntawm impurities xws li txhuas, calcium, carbon, leej faj, thiab phosphorus.

Steelmaking:

Tsawg aluminium (piv txwv li tsawg dua lossis sib npaug ntawm 2.5%) thiab calcium (ca tsawg dua lossis muaj calsecium - inducions inclusions.

Casting Hlau:

Yuav tsum tau ua cov duab kos, tab sis leej faj (p tsawg dua los yog sib npaug lossis sib npaug los yog sib npaug los yog sib npaug los ntawm cov porosity thiab txias brittleness hauv castings.

Cov Kev Siv Tshwj Xeeb:

Piv txwv li, hauv kev tsim cov qis qis - sib nqus hlau, cov khoom sib nqus xws li titanium (ti tsawg dua los yog sib luag rau 0.05%) yuav tsum tau txwv nruj me ntsis.

2. Sib Xws Li Lub Cev thiab Loj

Lumps:

Haum rau batch ntxiv rau loj steelmak sov furnacakes. Lawv yooj yim thauj thiab khw muag khoom, thiab tsis muaj kev nqus dej noo, tab sis yuav tsum tau crushing ua ntej siv.

Granulars:

Uniform loj (piv txwv li, 10 {{{{}}}}} 50 ua rau lawv haum rau cov chaw sov thiab nruab nrab lossis nruab nrab. Lawv muab cov tshuaj tiv thaiv ruaj khov thiab txo qis plua plav tsis muaj kuab paug.

Hmoov:

Qhov loj me (piv txwv li, 0.1-1 mm) feem ntau siv raws li cam khwb cia hlau inoculants lossis electrode txheej txheej. Lawv xav tau txoj kev tiv thaiv noo noo (lawv muaj feem dhau kev nqus dej noo thiab agglomeration) thiab xav tau ntim khoom.
