Ferrosilicontuaj yeem faib rau hauvferrosilicon 75, ferrosilicon 72, Ferrosilicon 45, thiab lwm yam raws li cov ntsiab lus silicon:
Cov ntsiab lus silicon yog nruab nrab ntawm 72% thiab 8 {0}%, uas yog hom ferrosilicon. Piv txwv, Fesi {{75- b, nrog cov ntsiab lus silicon ntawm 72. {%}}}}} {}. Lub zog, hardness thiab lwm yam khoom ntawm cov hlau. Nyob rau hauv lub foundry kev lag luam, nws kuj tseem tuaj yeem siv ua ib qho inoculant los txhim kho tus qauv thiab cov khoom ntawm cov hlau cam khwb cia.
Cov ntsiab lus silicon yog nruab nrab ntawm 65. 0% thiab 72. {}}}%. Nws yog tsuas yog siv nyob rau hauv qee cov txheej txheem steel ntau lawm nrog cov ntsiab lus qis qis, xws li kev tsim cov roj carbon steel, mus ua si deoxidation thiab qee lub luag haujlwm.
Cov ntsiab lus silicon yog nruab nrab ntawm 4 {{0. {{{}}}% Thiab 47.0%. Vim nws cov ntsiab lus silicon qis thiab tus nqi qis, nws yog siv rau hauv ib qho kev lag luam uas tsis paub txog ferroalloys uas tsis xav tau cov ntsiab lus silicon siab.
Ferrosilicon tau muab faib ua ntau qib xws li 75, 72, thiab 70 rau cov laj thawj hauv qab no:
Kom tau raws li cov kev xav tau sib txawv
Steelmaking:
Ntau hom hlau muaj sib txawv rau cov ntsiab lus silicon. Piv txwv li, nyob rau hauv kev tsim cov qauv hlau, ferrosilicon nrog cov ntsiab lus sidicon ntawm 72 lossis 75 tuaj yeem txhim kho lub zog, tawv tawv, thiab elasticity ntawm cov hlau. Txawm li cas los xij, rau qee cov hlau tshwj xeeb, xws li cov ntsiab lus ntau silicon, nws yuav tsim nyog los xyuas kom meej cov khoom seem, yog li muab cov hlau tshwj xeeb lossis tshuaj lom neeg , xws li siab sib nqus permeability thiab corrosion tsis kam.
Nrhiav Kev Lag Luam:
Ntxiv cov ferrosilicon kom cam khwb cia hlau tuaj yeem siv ua cov oneoculant rau cov hlau ductab. Ferrosilicon nrog cov ntsiab lus sib txawv silicon muaj cov teebmeem sib txawv hauv kev txhawb nqa graphitization thiab txhim kho cov qauv sab hauv thiab kev ua tau zoo ntawm cov pov tseg. Ferrosilicon nrog cov lus silicon ntawm kwv yees li 72 tuaj yeem pab siv zog cov duab thiab txhim kho lub zog thiab kev tawv ntawm cov castingings.
Lwm Teb:
Thaum tsim cov khoom siv tshuaj lom xws li silicone thiab raws li cov ntsiab lus txo qis rau cov ferrosalloys, ferrosalicon nrog cov qhab nia siab dua, yog qhov yuav tsum tau ua kom muaj kev ua haujlwm ntawm cov tshuaj tiv thaiv thiab cov zoo ntawm cov khoom.
Xav txog qhov sib txawv hauv qhov zoo thiab tus nqi
Cov Yam Zoo:
Qeb siab ntawm ferrosilicon txhais tau tias yog cov ntsiab lus silicon siab thiab cov ncauj lus tsis huv. Thaum siv, tus nqi ntxiv tuaj yeem tswj tau ntau dua los txo cov kev cuam tshuam tsis zoo ntawm cov khoom lag luam, thiab cov khoom lag luam zoo dua thiab kev ua tau zoo dua. Piv txwv li, hauv zus tau cov khoom lag luam qib siab, siv cov qib siab ferrosilicon tuaj yeem ua rau cov steel purer thiab txhim khu kev qha steel.
Tus nqi yam:
Kev tsim cov qib sib txawv ntawm ferrosilicon muaj cov nqi khoom sib txawv, cov txheej txheem ntau lawm, thiab siv zog ntau zog. Feem ntau hais lus, ntau dua cov ntsiab lus silicon ntawm ferrosilicon, qhov nyuaj dua nws yog tsim thiab cov nqi siab dua. Muab qhab nia ferrosilicon tso cai rau cov neeg siv xaiv cov khoom lag luam raws li lawv cov nqi xav tau tiag tiag thiab kev them nyiaj siv rau them nyiaj ntxiv rau kev ua kom muaj kev coj dawb huv.
