Ferroalloys yog cov khoom siv hlau ua los ntawm cov hlau nrog qhov sib ntxiv ntawm ib lossis ntau dua lwm cov ntsiab lus. Cov alloys no tau siv dav hauv kev tsim steel, foundry, fais fab, tshuaj, aerospace thiab lwm yam kev lag luam vim lawv cov khoom sib txawv. Lub luag haujlwm tseem ceeb ntawm ferroalloys suav nrog kev txhim kho lub cev thiab lub zog ntawm cov hlau, ua kom yooj yim deoxidation thiab desulphurisation hauv cov txheej txheem steelmaking, thiab ua cov khoom siv raw rau smelting steel.
hom ferro alloy feem ntau
1. Ferrosilicon (FeSi)
- Muaj pes tsawg leeg: Ib qho alloy ntawm hlau thiab silicon, feem ntau muaj 15-90% silicon.
- Siv: Feem ntau yog siv los ua deoxidiser thiab alloying ntsiab additive hauv steelmaking. Hauv kev lag luam foundry, ferrosilicon kuj yog ib qho tseem ceeb ntawm cov inoculants thiab spheroidising agents.
2. Ferromanganese (FeMn)
- Muaj pes tsawg leeg: Ib qho alloy ntawm hlau thiab manganese, feem ntau nrog cov ntsiab lus manganese ntawm 60-80%.
- Siv: Ferromanganese yog siv los ua deoxidising thiab desulphurizing tus neeg sawv cev hauv cov txheej txheem steelmaking, ntxiv rau txhim kho hardness, toughness thiab hnav tsis kam ntawm steel. Nws yog dav siv nyob rau hauv kev tsim kho steel, cuab yeej steel thiab stainless hlau.
3. FeCr
- Muaj pes tsawg leeg: Ib qho alloy ntawm hlau thiab chromium nrog cov ntsiab lus chromium ntawm 50-70%.
- Siv: Feem ntau yog siv rau hauv kev tsim cov hlau tsis huv thiab cov hlau tsis muaj cua sov. Ferrochrome tsub kom corrosion kuj, hardness thiab lub zog ntawm steel. 4.
4. Ferro Vanadium (FeV)
- Muaj pes tsawg leeg: Ib qho alloy ntawm hlau thiab vanadium nrog cov ntsiab lus vanadium feem ntau yog li ntawm 35-85%.
- Siv: Ferro Vanadium yog siv los ua ib qho kev sib xyaw ua ke los txhim kho lub zog, tawv thiab hnav tsis kam ntawm cov hlau, thiab yog siv dav hauv kev tsim cov khoom muaj zog qis alloy steels thiab cov cuab yeej steel.
5. FeTi
- Muaj pes tsawg leeg: alloy hlau thiab titanium, titanium cov ntsiab lus feem ntau yog 20-75%.
- Siv: Siv los ua deoxidiser thiab desulphuriser hauv steelmaking, kuj siv rau hauv kev tsim cov hlau muaj zog thiab kub-resistant steel.
6. Ferrous molybdenum (FeMo)
- Kev sib xyaw: Alloy ntawm hlau thiab molybdenum, molybdenum cov ntsiab lus feem ntau yog nyob nruab nrab ntawm 50-75%.
- Siv: Ferro Molybdenum yog siv dav hauv kev tsim cov hlau tsis muaj steel, cov cuab yeej hlau thiab cov hlau tsis muaj cua sov. Qhov sib ntxiv ntawm molybdenum txhim kho cov hlau hnav tsis kam, hardness thiab tsis kam mus rau qhov kub thiab txias.
7. FeNi
- Cov khoom xyaw: Cov hlau thiab npib tsib xee nrog cov ntsiab lus nickel ntawm 20-90%.
- Siv: Feem ntau yog siv rau hauv kev tsim cov hlau tsis muaj hlau thiab cov hlau tsis muaj cua sov. Nickel-hlau alloys txhim kho corrosion kuj, kub tsis kam thiab lub zog ntawm cov hlau. 8.
8. FeSiMn
- Muaj pes tsawg leeg: Alloy hlau, silicon thiab manganese.
- Siv: Raws li deoxidiser thiab alloying additive nyob rau hauv steelmaking, nws kuj txhim kho cov neeg kho tshuab zog thiab tshuaj muaj pes tsawg leeg ntawm hlau.
ferro alloy tseem ceeb siv
- Cov khoom siv raw rau cov hlau ua: Ferroalloys yog siv los ua cov khoom sib txuas ntxiv thaum lub sij hawm tsim cov hlau los tswj cov khoom siv hlau thiab txhim kho cov neeg kho tshuab (xws li lub zog, toughness, abrasion resistance, etc.) thiab tshuaj (xws li corrosion thiab oxidation. tsis kam, thiab lwm yam) cov khoom ntawm steel.
- FOUNDRY INDUSTRY: Nyob rau hauv cov txheej txheem casting, ferroalloys feem ntau yog siv los ua inoculants thiab spheroidising agents los txhim kho qhov zoo ntawm castings.
- Kev lag luam hluav taws xob thiab tshuaj lom neeg: Qee cov ferroalloys xws li ferrochrome thiab ferro-nickel yog siv los tsim cov khoom siv hluav taws xob thiab tshuaj lom neeg vim lawv cov khoom siv hluav taws xob siab thiab corrosion kuj.
