Nyob rau hauv lub loj teb kev lag luam ntau lawm,ferrosilicon 72tau dhau los ua qhov tsis tseem ceeb thiab cov khoom tseem ceeb hauv ntau qhov kev lag luam vim nws qhov kev ua tau zoo tshwj xeeb. Fesi72 muaj npe vim yog nws cov lus silicon ntawm kwv yees li 72%. Nws tseem muaj cov hlau thiab ib qho me me ntawm cov pa roj carbon, manganese, phosphorus, leej faj thiab lwm yam ntsiab. Nws cov deoxidation zoo, kev sib dhos thiab inoculation tej yam ua rau nws ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam.
Kev lag luam steelmaking: Cov deoxidizing thiab alloying cov khoom siv raw
72 ferrosilicon yog ib qho tseem ceebDeagidizer hauv steelmakingKev lag luam, kuj tau pab ib txoj haujlwm sib xws, thiab tsim nyog rau kev tsim cov khoom lag luam steel:
Kev Siv Deigidation:
Nyob rau hauv Converter thiab Fais arc rauv taws ua kom muaj zog rau kev ua ntej-deoxidation lossis kev sib txuas ntawm 0.4% -0.7% ntawm Molten Steel loj. Silicon reacts sai nrog oxygen nyob rau hauv molening steel los tsim cov ntsiab lus oxygen
Alloying Ntxiv:
Nws pab txhawb nqa-alloy High-zog hlau thiab cov qauv txheem hlau nrog silicon, nce lub zog thiab hardness ntawm cov hlau tsis muaj kev txo qis tawv. Piv txwv li, hauv kev tsim cov Q355 cov hlau tsis muaj zog, ntxiv 72 # ferrosilicon tuaj yeem nce lub zog ntawm cov hlau uas muaj 10%, sib ntsib cov neeg ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm.
Cov xwm txheej haum:
Haum rau me me thiab nruab nrab steel mills tsim cov hlau ua hlau, cov hlau diav tsawg, boiler steel, thiab ntsuas dazidation sib npaug nrog cov nqi-ua hauj lwm zoo.
Nrhiav Kev Lag Luam: cam khwb cia hlau inoculation thiab kev ua tau zoo ua kom zoo
Hauv kev tsim cov hlau thiab cov hlau cam khwb cia cam khwb cia, ferrosilicon 72% yog siv deoxident feem ntau, ua tiav ob qho tib si deoxidation thiab microstructure optimization:
Inoculation nyhuv:
Ntxiv ntawm 0.2% -0.5% ntawm cov hlau loj, sillicon txhawb nqa cov txheej txheem graphite, thiab tiv thaiv kom tiv thaiv kev tsim cov hlau nrag dawb.
Kev Txhim Kho:
Muaj peev xwm nce qhov kev cuam tshuam nyuaj ntawm Grey cam khwb cia hlau los ntawm 20% -30% thiab lwm yam khoom nrog cov khoom siv hluav taws xob uas yuav tsum muaj.
Qhov Zoo:
Piv rau high-silicon ferrosilicon (xws liFesi75), Fesi 72% yog tsawg dua thiab muaj cov ntsiab lus impurity (xws li Carbon, ua haum rau Casting cov ntawv thov yuav tsum muaj kev coj noj coj ua.
Ferrroalloy kev tsim khoom: Txo cov neeg sawv cev thiab muaj kev tswj hwm
Nyob rau hauv smelting ntawm lwm ferroalloys (xws li silicon-manganese alloys thiabSilicon-Chromium alloys), ferrosilicon # 72 pab raws li tus neeg sawv cev txo tus neeg sawv cev thiab muaj kev sib xyaw ntxiv:
Txo:
Siv cov khoom muaj zog muaj zog ntawm silicon, nws txo cov oxides xws li silicon dioxide hauv cov ore, kev pab hauv kev tsim ntawm lub hom phiaj ferroalloy. Piv txwv li, hauv kev tsim cov khoom silicon-manganese alloys, ferrosilicon alloy 72 tuaj yeem txo cov smelting kub thiab txhim kho cov tshuaj tiv thaiv kev ua haujlwm.
Composition kev cai:
Nws pab txhawb cov ntsiab lus silicon hauv cov alloy, meej tswj cov khoom ntawm cov khoom lag luam thiab ua kom muaj txiaj ntsig thiab silicon-chromium alloys cov qauv kev lag luam.
Lwm cov ntaub ntawv tshwj xeeb kev lag luam
Vuam Cov Ntaub Ntawv Kev Lag Luam:
Raws li cov khoom siv raw ntawm vuam hluav taws xob thiab cov roj ntsha, ua kom haum rau cov khoom siv hluav taws xob, ua kom haum rau cov qauv siv hluav taws xob, kev siv hluav taws xob vuam, thiab lwm yam kev siv.
Cov hlau uas tsis yog ferrous:
Hauv kev tsim cov aluminium thiab cov hlau nplaum Magnes, ntxiv cov khoom siv tsis zoo, ua kom muaj zog ntxiv rau 0.3%) tuaj yeem ua kom muaj zog ntawm 0.3%) tuaj yeem kho lub zog aluminium (tsawg dua los yog sib npaug ntawm cov log tsheb thiab cov khoom siv sib txawv.
Tshuaj Kev Lag Luam:
Siv nyob rau hauv kev tsim cov silicides (xws li cov nplais thiab silicones). Cov silicon hauv ferrosilicon reacts nrog rau lwm cov ntaub ntawv lom neeg cov khoom lag luam, uas tau siv dav hauv cov khoom siv inorgants, cov roj nplua nyeem, txheej, thiab lwm thaj teb.
Kev thov cov txiaj ntsig thiab xaiv lub cav ntawm 72 # ferrosilicon
Cov ntsiab lus zoo:
Ntsuas cov ncauj lus silicon, noj mus rau hauv tus account deoxidation, inoculation, thiab alloy kev ua haujlwm; tus nqi qis dua li high-silicon ferrosilicon, tus nqi siab-ua hauj lwm zoo; Cov ntsiab lus tsis sib xyaw Ifrollable, haum rau cov kev xav tau ntawm nruab nrab-rau-high-end-kawg muaj khoom.
Xaiv cov ntsiab cai:
Rau cov ntawv thov uas yuav tsum tau txais kev deoxidation siab heev thiab zoo li cov kabmob steel thiab Precision Castings), Fesi75 tuaj yeem xaiv; Rau cov ntawv thov raug nqi them tus nqi nrog cov kev ua tau zoo (xws li cov hlau sib txawv thiab cov khoom siv dav dav), 72 Ferrosilicon yog qhov kev xaiv zoo; Rau cov ntawv thov xws li tsis yog-ferrous hlau smroting thiab kev siv tshuaj lom neeg, tus nqi ntxiv thiab kev tsis loj thiab xyaum tswj kev yuav tsum tau hloov kho raws li cov txheej txheem tshwj xeeb.
