Ferrophosphorus (FeP) yog ib qho hlau uas muaj hlau thiab phosphorus, feem ntau yog siv hauv steel smelting thiab alloy manufacturing. Ferrophorus feem ntau muaj li ntawm 20% ~ 30% phosphorus, thiab seem ntawm cov muaj pes tsawg leeg yog hlau. Raws li ib qho tseem ceeb ntawm cov khoom siv hlau nrog cov khoom siv tshuaj lom neeg thiab cov khoom siv hlau, ferrophosphorus muaj ntau yam kev siv hauv ntau qhov chaw lag luam.
ferro phosphorus loj siv
1. Hlau smelting
- Deoxidizer thiab alloy additive: Ferro-phosphorus feem ntau yog siv los ua deoxidizer hauv steel smelting. Nws tuaj yeem tshem tawm cov pa oxygen hauv cov hlau zoo, thiab tib lub sijhawm muab phosphorus cov ntsiab lus los tswj cov ntsiab lus ntawm phosphorus hauv cov hlau. Phosphorus muaj qhov cuam tshuam tseem ceeb ntawm hardness, toughness thiab hnav tsis kam ntawm steel, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov steels tshwj xeeb, hlau phosphorus yog indispensable.
- Kev tsim cov hlau muaj zog: Cov ntsiab lus phosphorus txhim kho qhov hnav tsis kam ntawm cov hlau, yog li ntawd, ferrophosphorus feem ntau yog siv los tsim cov hlau muaj zog uas yuav tsum tau hnav tsis kam thiab siab hardness.
2. Kev tsim cov alloys:
- Phosphorus Alloys: Ferro-phosphorus yog siv los ua ib qho chaw phosphorus hauv kev tsim cov hlau thiab yog siv dav hauv kev tsim cov phosphorus alloys (xws li phosphorus tooj liab alloys, phosphorus aluminium alloys, thiab lwm yam). Los ntawm kev kho cov ntsiab lus phosphorus hauv ferro-phosphorus, cov khoom ntawm cov hlau tuaj yeem raug kho kom tau raws li cov kev xav tau ntawm kev siv sib txawv.
- Corrosion Resistant Alloys: Phosphorus tuaj yeem txhim kho corrosion thiab oxidation tsis kam ntawm qee cov hlau, thiab ferro-phosphorus yog li ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom tshwj xeeb corrosion resistant.
3. Foundry kev lag luam:
- Ferro-phosphorus kuj tseem siv rau hauv kev lag luam foundry, feem ntau yog ib qho ntxiv rau cam khwb cia hlau alloys. Los ntawm kev ntxiv ferrophosphorus rau cam khwb cia hlau, nws txhim kho lub fluidity thiab castability ntawm cov cam khwb cia hlau thiab ua rau kom cov hnav tsis kam ntawm cov castings.
4. Kev lag luam Electronics:
- Kev kho phosphate: Hlau phosphorus tuaj yeem siv rau kev kho deg hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog cov khoom siv rau kev kho phosphate ntawm cov hlau nto, txhim kho corrosion kuj thiab oxidation tsis kam ntawm hlau.
5. Kev lag luam tshuaj:
- Kev tsim cov phosphorus tebchaw: Hlau phosphorus yog cov khoom siv raw rau kev tsim ntau cov phosphorus tebchaw, tshwj xeeb tshaj yog rau kev tsim cov phosphorus hauv kev ua liaj ua teb chiv, lossis rau kev tsim cov tshuaj phosphorus-based.
ferro phosphorus cov yam ntxwv
1. Cov ntsiab lus phosphorus siab:
- Hlau phosphorus feem ntau muaj phosphorus siab, feem ntau ntawm 20% thiab 30%. Nws cov ntsiab lus phosphorus tuaj yeem hloov kho kom tau raws li cov kev xav tau sib txawv.
2. Txhim kho cov khoom steel:
- Ferro-phosphorus tuaj yeem txhim kho hardness, hnav tsis kam thiab lub zog ntawm cov hlau. Tshwj xeeb tshaj yog nyob rau hauv kev tsim cov high-strength steels, hnav-resistant steels thiab tej yam tshwj xeeb alloy steels, ferrophosphorus yog indispensable.
3. Deoxygenation:
- Ferro-phosphorus muaj peev xwm deoxidizing zoo, uas tuaj yeem tshem tawm cov pa oxygen hauv cov kua hlau thaum lub sij hawm steel smelting txheej txheem, txo cov porosity hauv cov hlau, thiab txhim kho qhov zoo thiab purity ntawm cov hlau.
4. Corrosion kuj:
- Phosphorus tuaj yeem txhim kho corrosion kuj ntawm qee cov ntaub ntawv hlau, yog li hlau phosphorus plays lub luag haujlwm tseem ceeb hauv kev tsim cov hlau thiab cov khoom siv corrosion-resistant.
5. Yooj yim ntawm smelting:
- Ferro-phosphorus yog ib qho yooj yim los tsim nyob rau hauv cov txheej txheem smelting thiab yog ib tug nqi-zoo raw khoom rau alloys vim hais tias ntawm nws cov nqi qis piv rau lwm cov ntaub ntawv alloy.
