Npauj Hlau thiab Phosphorus npua hlau yog hlau alloys tau los ntawm smelting hlau ore, tsuas yog cuam tshuam hauv cov tshuaj lom neeg, smelting txheej txheem thiab siv. Qhov sib txawv tau piav qhia meej hauv cov ncauj lus hauv qab no.
Qhov sib txawv ntawm npua hlau thiab phosphorus npua hlau
1. Tshuaj lom neeg sib xyaw
- Npua Hlau:Npua Hlau yog thawj cov hlau sib xyaw tau los ntawm smelting hlau ore ntawm 2% thiab muaj cov tshuaj tua kab mob xws li, manganese, phosphorus. Vim nws cov ntsiab lus carbon ntau, cov hlau npua tsis haum rau kev ua pov thawj lossis tsim cov khoom siv high-zog steel cov khoom lag luam hauv kev lag luam metallurgical.
- Phosphorus npua hlau:Phosphorus npua hlau yog hlau hlau uas muaj cov hlau siab (p) siab rau hauv cov hlau kub thaum lub zog smelting. Cov ntsiab lus phosphorus feem ntau, feem ntau yog nruab nrab {{{{}}}}}}}}}}. 3%, qee zaum tuaj yeem ncav cuag ntau dua 1.5%. Phosphorus yog ib qho teeb meem tseem ceeb hauv npua hlau, thiab muaj cov tshuaj phosphorus yuav cuam tshuam rau cov tawv nqaij thiab kev sib luag, tshwj xeeb ntawm cov kub tsawg.

2. SMELTING Txheej Txheem
- Npua Hlau SMELTING:Npua hlau feem ntau yog tsim los ntawm cov khoom siv raw xws li hlau ore, coke thiab limestone hauv cov tshuab hluav taws kub. Los ntawm kev tawm tsam txo nyob rau hauv lub zog tawg, cov pa thiab cov pa roj carbon monoxide, thiab cov pa roj ntsha yuav txo cov hlau ua kua kom ua cov hlau ua kua.
- Smelting ntawm phosphorus npua hlau:Qhov tsim ntawm phosphorus npua hlau feem ntau cuam tshuam nrog cov khoom siv raw thiab qhov kub nyob hauv cov cua sov, cov khoom siv pa oxygen thiab lwm yam. Yog tias cov hlau ore siv hauv lub moj tej tawg muaj qhov siab phosphorus cov ntsiab lus, lossis phosphorus-muaj cov ees (phosphorus-muaj cov ores) Ib qho ntxiv, yog tias tsis muaj cov pa tsw txaus thaum lub ntsej muag smelting, nws kuj yooj yim ua rau kom muaj kev nce ntxiv hauv cov ntsiab lus ntawm phosphorus.

3. Cov nyhuv ntawm phosphorus ntawm hlau
- Phosphorus nyob rau hauv npua hlau:Cov ntsiab lus phosphorus hauv npua hlau feem ntau yog tsawg, thiab phosphorus yog feem ntau yog ib qho ntawm cov impurities hauv cov txheej txheem smelting. Txawm hais tias muaj phosphorus yuav cuam tshuam rau qhov zoo ntawm cov hlau cam khwb cia, nws feem ntau nws tsis ua rau cov hlau nrum, tshwj xeeb tshaj yog nyob rau hauv kev nrum hlau, cov ntsiab lus ntawm phosphorus tau txais.
- Phosphorus nyob rau hauv npua hlau:Lub xub ntiag ntawm phosphorus muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm cov hlau, tshwj xeeb tshaj yog rau cov khoom lag luam steel. Phosphorus ntawm qhov kub siab yuav ua rau muaj hlau loj dua ntawm cov hlau, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem txias, cov txiaj ntsig phosphorus tshwj xeeb tshaj yog muaj tshwj xeeb. Thaum cov ntsiab lus ntawm phosphorus hauv cov hlau yog qhov siab, qhov nruj ntawm cov hlau yuav raug txo qis, uas yog qhov yooj yim los ua rau brittle backstre. Yog li ntawd, phosphorus npua hlau feem ntau tsis siv los tsim cov qauv hlau zoo, feem ntau cov qauv tsheb thiab lwm yam uas yuav tsum muaj qhov zoo.

4: Siv
- Npua Hlau:Npua hlau yog feem ntau siv rau cov cam khwb cia, tshwj xeeb yog rau kev tsim cov hlau nplaum cov khoom lag luam (xws li cov kav dej cam khwb (xws li cov kav dej cam khwb cia (xws li cov kav dej, qhov chaw, thiab lwm yam). Cov txiaj ntsig cov roj carbon ntau dua hauv cov hlau hlau yog qhov haum rau kev ua pov, tab sis tsis haum rau kev tsim cov khoom siv cov khoom siv hlau siab. Txhawm rau ua cov hlau, hlau hlau yuav tsum dhau los ntawm cov txheej txheem statmaking ntxiv kom tshem tawm cov pa roj carbon ntau thiab impurities.
- Phosphorus npua hlau:Phosphorus npua hlau yog feem ntau siv nyob rau hauv kev tsim cov khoom tshwj xeeb pov tseg, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv uas yuav tsum tau ua ib qho kev sib dhos. Piv txwv li, qee yam High-phosphorus cam khwb cia hlau tuaj yeem siv los tsim cov kev hnav tshwj xeeb hnav cov khoom tiv thaiv. Txawm li cas los xij, phosphorus npua hlau tsis haum rau kev tsim cov hlau lossis cov khoom siv hlau siab tuaj yeem cuam tshuam rau cov khoom siv tshuab ntawm cov khoom kawg ntawm cov khoom kawg.

5. Kev kho mob thiab tshem tawm ntawm phosphorus
- Phosphorus tshem tawm:Cov txiaj ntsig tsis zoo ntawm phosphorus ntawm cov khoom siv steel ua rau cov neeg tsim qauv hlau feem ntau xav tshem nws ntau li ntau tau. Hauv cov txheej txheem smelting, ntau txoj hauv kev tuaj yeem siv los txo cov phosphorus cov ntsiab lus, xws li:
- Converter steelmaking:Los ntawm cov pa thev naus laus zis, lub phosphorus hauv cov hlau kub yog oxidized rau phosphoric acid, thiab tom qab ntawd tshem tawm ntawm cov hlau molten.
- Fais arc rauve smelting:Nws kuj tseem tuaj yeem txo cov ntsiab lus phosphorus kom ntau li ntau tau los ntawm kev tswj hwm qhov kev xaiv ntawm kev xaiv thiab cov pa oxygen ua haujlwm.
- Siv cov phosphorus npua hlau:Rau cov hlau kub nrog cov ntsiab lus siab phosphorus high Yog li ntawd, phosphorus npua hlau feem ntau yog siv nyob rau qee thaj chaw tshwj xeeb, thiab tsis yog siv ncaj qha rau cov hlau zoo.
Qhov sib txawv ntawm npua hlau thiab phosphorus npua hlau
Hauv cov ntsiab lus:
- Npua Hlau:Feem ntau yog hais txog thawj hlau Alloy Sffelted nyob rau hauv cov tshuab rawg, nrog cov ntsiab lus carbon ntau dua thiab qis dua phosphorus cov ntsiab lus. Npua hlau feem ntau yog siv rau kev ua pov thawj, lossis ntxiv ua kom zoo dua rau hauv cov hlau.
- Phosphorus npua hlau:Phosphorus npua hlau yog hais txog npua hlau muaj ntau dua cov khoom siv uas muaj ntau dua los yog cov ntsiab lus phosphorus loj dua. Phosphorus npua hlau muaj cov ntsiab lus zoo ntawm cov ntsiab lus tseem ceeb ntawm kev tsim cov hlau, thiab feem ntau tsis haum rau kev tsim cov qauv hlau uas yuav tsum muaj kev nyuaj thiab kev sib tw siab.
