Hauv steelmaking, kev xaiv ntawm ferrosilicon thiab ferromanganese tsis yog ib qho yooj yim "los yog" kev txiav txim siab; es, nws nyob ntawm tej yam khoom kawg uas koj xav muab rau cov hlau. Yooj yim muab tso, ferromanganese yog "jack- ntawm-tag nrho- kev lag luam," lub luag haujlwm rau kev deoxidation yooj yim thiab ntxiv dag zog, thaum ferrosilicon zoo li "cov tub rog tshwj xeeb," tsom rau kev xa cov khoom siv hluav taws xob tshwj xeeb.
Txhawm rau pab koj nkag siab qhov no kom meej meej, Kuv tau sau cov ntsiab lus sib txawv hauv cov lus hauv qab no:
| Cov khoom npe | Silico manganese (SiMn) | Cov khoom npe | Ferrosilicon (FeSi) |
| Lub luag haujlwm tseem ceeb: | Deoxidizer + Alloying Agent | Lub luag haujlwm tseem ceeb: |
Deoxidizer + Tshwj xeeb Alloying Agent |
| Kev Pabcuam Tseem Ceeb |
Cov txiaj ntsig tseem ceeb ntawm Manganese (Mn): 1. Cov deoxidation zoo heev, nrog cov khoom deoxidation uas ntab tau yooj yim rau saum npoo. 2. "Sulfur fixation": khi nrog kev puas tsuaj sulfur (S) los tiv thaiv kub luv luv hauv cov hlau. 3. Txhim kho lub zog thiab hardness: Txhim kho cov hlau toughness thiab hnav tsis kam. |
Kev Pabcuam Tseem Ceeb |
Cov txiaj ntsig tseem ceeb ntawm Silicon (Si): 1. Txhim khu kev sib nqus permeability thiab hluav taws xob tiv taus, uas yog cov khoom tseem ceeb ntawm cov hlau hluav taws xob (silicon steel). 2. Ua kom muaj kev txwv elastic, ua rau nws tsim nyog rau kev tsim cov hlau caij nplooj ntoos hlav. 3. Ua kom muaj cua sov ntau thaum lub sij hawm deoxidation, uas yuav pab txhawb qhov kub ntawm cov hlau molten. |

Hom Steel Qib rau kev siv |
Feem ntau ntawm kev lag luam steels, suav nrog carbon steel, qis- alloy steel, thiab siab - steel hlau. Nws tuaj yeem hais tias "steel tsis tuaj yeem ua yam tsis muaj manganese." |
Hom Steel Qib rau kev siv |
Cov qib steel tshwj xeeb xws li hluav taws xob silicon steel (rau transformer thiab lub cev muaj zog cores), caij nplooj ntoos hlav steel, thiab tshav kub- steel resistant. |
|
Tus Nqi thiab Cov Tswv Yim Rau Kev Sau Npe |
Raws li kev sib xyaw deoxidizer, nws muaj nqi zoo heev -kev ua tau zoo thiab feem ntau yog siv ua ke nrog ferrosilicon kom ua tiav cov txiaj ntsig deoxidation zoo dua. |
Tus Nqi thiab Cov Tswv Yim Rau Kev Sau Npe |
Vim nws cov ntsiab lus silicon siab (feem ntau 72% -80%), nws yog ib qho tseem ceeb ntawm cov qib steel tshwj xeeb. Kev saib xyuas yuav tsum tau ua thaum ntxiv kom tsis txhob slag los ua acidic. |
Synergy thiab Division of Labor hauv Steelmaking Process
Hauv kev tsim cov hlau tiag tiag, lawv ua haujlwm zoo ib yam li - pab pawg sib koom ua ke:
Lub "Vanguard" ntawm Deoxidation Theem: Cov txheej txheem ib txwm siv nrog ferrosilicon rau kev deoxidation ua ntej. Vim nws lub peev xwm deoxidizing muaj zog thiab cov tshuaj tiv thaiv exothermic, nws tsim cov kev mob zoo rau cov kauj ruam tom ntej.
"Lub zog tseem ceeb" ntawm Alloying: Manganese- silicon ntxiv rau siv manganese rau kev sib sib zog nqus deoxidation thiab sulfur fixation, muab lub hauv paus lub zog thiab hardness rau cov hlau.
Lub "Key Player" rau Cov Khoom Tshwj Xeeb: Thaum tsim cov hlau nrog cov khoom siv hluav taws xob tshwj xeeb (xws li silicon steel nplooj ntawv rau transformers), ferrosilicon yog ib qho irreplaceable core additive uas ho txhim khu cov hlau magnetic permeability.
Cov ntsiab lus
Rau kev tsim khoom ntawm feem ntau ntawm cov hlau zoo tib yam, silicomanganese yog qhov tseem ceeb tshaj plaws thiab siv dav xaiv, lub luag haujlwm los xyuas kom meej cov hlau zoo thiab cov khoom siv kho tshuab.
Yog tias koj lub hom phiaj yog kom ua tiav cov khoom siv hluav taws xob tshwj xeeb lossis ultra-siab elasticity, ferrosilicon yog tib txoj kev xaiv.
Yog li ntawd, tus yuam sij rau kev xaiv yog nyob rau hauv koj lub hom phiaj steelmaking: seb koj lub hom phiaj los tsim ib tug ruaj khov thiab ruaj khov steel qauv los yog ib tug haumxeeb hlau nrog zoo heev electromagnetic zog. Feem ntau, ob qho tib si sib ntxiv es tsis yog cov hloov pauv yooj yim.
