Ferrophosphorus yog cov hlau alloy uas muaj cov khoom siv phosphorus, feem ntau muaj cov hlau thiab phosphorus, nrog cov ntsiab lus phosphorus feem ntau yog li ntawm 18% mus rau 25%. Nws yog ib qho tseem ceeb additive siv nyob rau hauv zus tau tej cov hlau thiab cam khwb cia hlau los txhim kho cov neeg kho tshuab thiab txheej txheem zog ntawm cov khoom.
Cov yam ntxwv ntawm ferro phosphorus
1. Cov ntsiab lus Phosphorus siab: Cov ntsiab lus phosphorus ntawm ferro-phosphorus feem ntau yog nyob rau hauv thaj tsam ntawm 18% -25%. Phosphorus muaj nyob rau hauv daim ntawv ntawm cov khoom siv hauv cov hlau, uas tuaj yeem hloov cov microstructure ntawm cov khoom thiab yog li cuam tshuam rau nws cov kev ua tau zoo.
2. Hardness Enhancement: Qhov sib ntxiv ntawm phosphorus tuaj yeem ua rau cov tawv tawv ntawm cov hlau alloys tuaj yeem ua rau cov khoom siv los ua kom pom kev hnav zoo dua hauv qhov chaw muaj kev ntxhov siab.
3. Corrosion Resistance: Phosphorus tuaj yeem txhim kho corrosion kuj ntawm steel, tshwj xeeb tshaj yog tiv thaiv atmospheric corrosion.
4. Fluidity Enhancement: Hlau Phosphorus nyob rau hauv cam khwb cia hlau txhim kho cov fluidity ntawm cov hlau molten, uas yuav pab sau complex pwm, yog li ua finer castings.
5. Brittle: Txawm hais tias hlau phosphorus ua tau zoo hauv kev txhim kho hardness thiab ntws, nws cov ntsiab lus phosphorus siab tsub kom cov khoom brittleness, tshwj xeeb tshaj yog nyob rau hauv qis kub, thiab ua rau nws yooj yim rau tawg.
Kev siv ferro phosphorus
1. FOUNDRY INDUSTRY: Ferro-phosphorus yog siv los ua ib qho ntxiv hauv kev tsim cov hlau cam khwb cia, feem ntau los txhim kho cov fluidity ntawm cov hlau molten thiab tsim cov castings nrog cov duab complex, tshwj xeeb tshaj yog haum rau ua nyias-walled castings.
2. Hlau smelting: Hauv kev tsim cov hlau tshwj xeeb, ferrophosphorus yog siv los tswj thiab tswj cov phosphorus cov ntsiab lus ntawm cov hlau, yog li txhim kho nws cov hardness thiab corrosion kuj. Phosphorus-muaj steels feem ntau yog siv rau hauv kev tsim cov choj, cov qauv tsim thiab cov kav dej uas yuav tsum tau muaj kev tiv thaiv corrosion.
3. Carbide Manufacturing: Ferro-phosphorus kuj tseem siv rau hauv qee cov cemented carbides los muab siab hardness thiab hnav tsis kam rau cov khoom, uas yog siv dav hauv cov cuab yeej txiav, pwm thiab lwm yam.
4. Deoxidizer thiab Alloying Agent: Iron Phosphorus yog qee zaum siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv cov txheej txheem steelmaking los pab tshem tawm cov pa oxygen thiab kho cov txheej txheem ntawm cov hlau.
Ferro phosphorus daim ntawv thov kev lag luam
- Hlau smelting: siv nyob rau hauv zus tau tej cov high-strength, corrosion-resistant structural thiab pipeline steel.
- Casting: Siv dav hauv kev tsim cov hlau cam khwb cia, tshwj xeeb tshaj yog cov uas xav tau cov qauv zoo thiab cov duab nyuaj.
- Alloys thiab Cemented Carbides: siv rau hauv kev tsim khoom ntawm qee qhov tshwj xeeb cemented carbides los txhim kho qhov hnav tsis kam thiab lub zog ntawm cov ntaub ntawv.
Ferro-phosphorus yog ib qho tseem ceeb alloying ntsiab nyob rau hauv steel kev lag luam thiab foundry, muaj peev xwm ua tau raws li cov kev xav tau kev lag luam tshwj xeeb thaum txhim kho cov khoom siv.
