Qhov sib xyaw ua ke sib txawv no muab ferrosilicon 72 # ib qho zoo dua hauv-, ua tsaug rau nws cov ntsiab lus uas muaj zoo li cas hauv cov khoom siv hlau nplaum.
Steelmaking Scenario: Kev ua haujlwm sib txawv ntawm Deagidation thiab Kev Siv
Hauv cov txheej txheem statmaking, cov tub ntxhais lub zog ntawmFERRO SiliconYog deoxidation thiab kev sib dhos, tab sis daim ntawv thov cav of Fesi72 thiab 75 txawv:
1. Deoxidation Function: Kev Lag Luam - tawm ntawm kev ua tau zoo thiab tus nqi
Silicon muaj lub zog ua kom muaj kuab lom rau oxygen, ua nws indispensable deoxidizing hauv statmaking statmaking. Vim nws cov ntsiab lus silicon ntau dua, 75 # ferrosilicon muaj deoxidation txuag 10% {}} 15% siab dua 72 # ferrosilicon. Nws tuaj yeem tshem tawm cov pa sai sai los ntawm cov hlau Molten, txo cov roj oxide, thiab txhim kho kev txhim kho cov hlau. Hauv kev tsim cov high-zog hlau thiab hluav taws xob hlau, uas tas li yuav tsum tau nruj polity ua, 75% ferrosilicon yog qhov kev xaiv zoo. Piv txwv li, 4-5 kg ntawm 75% FESI yuav tsum tsim ib qho tuj ntawm cov hlau hluav taws xob kom ntseeg tau tias cov hlau lub sib nqus permeability thiab kev kub ntxhov.
Ferrosilicon72, vim nws tus nqi ua nqi tau txais txiaj ntsig, yog siv dav rau deoxidation ntawm cov roj hmab grades xws li qis} almoy qauv hlau thiab caij nplooj ntoo hlav. Txawm hais tias nws tus deoxidation me ntsis yog qeeb qeeb, nws tuaj yeem ua tau cov nyiaj deoxitation ntxiv thaum txo tus nqi ib zaug thaum txo tus nqi ib zaug thaum 8 {}} 12 yuan. Cov ntaub ntawv los ntawm cov zeb hlau qhia tau hais tias tom qab siv 72% fesi rau deoxidation, oxide sib xyaw ua ke ntawm cov qauv hlau tsawg kuj tseem tuaj yeem tswj hwm hauv qab 0.03%, ntsib cov qauv kev lag luam.
2. Cov nyhuv alloying: meej phim ntawm cov yam ntxwv
Raws li ib qho kev sib ntxiv ntxiv, silicon txhim kho lub zog, hardness, thiab elasticity ntawm steel. Fesi75, vim nws qhov ruaj khov sib xyaw, feem ntau siv nyob rau hauv high-}}}} Cov ntsiab lus Steel uas yuav tsum tau kho kom meej cov ntsiab lus silicon. Piv txwv li, ntxiv silicon ferro 75 rau silicon steel tuaj yeem ua tiav cov khoom sib faib sillicon faib thiab txo cov hysteresis poob los ntawm ntau dua 30%. Fesi72, ntawm qhov tod tes, tsim nyog rau cov ntawv thov uas yuav tsum tau ua cov lus si silicon. Piv txwv li, hauv cov kabmob steel ntau lawm, ntxiv 72% fesi tuaj yeem siv cov ntsiab lus silicon ntawm 0.4% -0.8%, tswj kev sib npaug ntawm kev nyuaj thiab tawv.
Casting Daim Ntawv Thov: Txawv hauv Inoculation thiab Spheriding Cov teebmeem
Hauv kev lag luam casting, FESI alloy feem ntau ua haujlwm ua ib qho inoculant thiab spheroiding tus neeg sawv cev. Lawv cov kev siv sib txawv raws li kev tswj hwm mob thiab kev ua kom zoo li cas:
1. Inoculation: Tus yuam sij rau kev tswj hwm graphite nag
Tus yuam sij rau inoculation yog txhawb nqa cov ris tsho nraaj nraaj nraaj thiab kev txhim kho cov khoom pov thawj. FERRO Silicon 72, vim nws cov ntsiab lus carbon qis (tsawg dua los yog sib npaug rau cov inoculation rau inoculation ntawm cov hlau hlau thiab malleable cam khwb cia hlau. Cov kev sim tau qhia tias ntxiv 0.3% -0.6% Ferrosilicon tau nce cov hlau ntawm cov duab ntawm lub zog ntawm cov casting mus rau ntau dua 500 mpa.
FERRO Silicon 75, vim nws cov ntsiab lus siab siab (ntau dua lossis sib npaug nrog 1.5%), muaj cov txiaj ntsig zoo hauv Grey khawm hlau inoculation. Qhov tso tawm txhuas ua ke nrog nitrogen hauv cov hlau molten rau cov nuclei rau graphite nucleation lub sij hawm kom ntau dua 25 feeb. Lub chaw tsim khoom dej siv ferrosilicon alloy 75 inoculation txo nws cov nqi seem ntawm 8% thiab txhim kho kev hnav tsis kam los ntawm 20%.
2. Kev Pab Them Nqi Zog: Cov nyhuv synergistic rau kev ua tau zoo
Hauv cov kav hlau cadile ntau lawm, 72Ferrosilicon feem ntau yog siv hauv kev sib xyaw nrog cov hlau nplaum magots raws li tus neeg sawv cev sib xyaw. Nws cov ncauj lus tsis sib cais tiv thaiv kev noj ntawm spheriding cov ntsiab lus thiab kev txhim kho lub rheres ntawm graphite spheres los ntawm tuab {}} walled casting. Los ntawm kev ntxiv 75
