Cov qib sib txawv ntawm ferro phosphorus alloy sib txawv li cas?

Raws li ferro alloy nrog cov ntawv thov tseem ceeb hauv kev lag luam,ferrophosphorus alloyyog tsim los ntawm phosphorus thiab hlau, thiab tseem muaj impurities xws li silicon, manganese, carbon, thiab sulfur. Vim nws cov khoom tshwj xeeb, nws ua lub luag haujlwm tseem ceeb hauv kev lag luam xws li steelmaking thiab casting. Muaj qhov sib txawv ntawm qhov sib txawv ntawm cov qib sib txawv ntawm ferro phosphorus alloys, thiab qhov sib txawv no cuam tshuam ncaj qha rau kev ua haujlwm thiab kev siv ntau yam ntawm ferrophosphorus alloys. cov

FeP alloys feem ntau yog graded raws li cov ntsiab lus phosphorus thiab lwm yam impurity. Hauv cov qauv kev faib tawm, raws li cov ntsiab lus phosphorus, nws tuaj yeem muab faib ua plaub hom:FeP24 (P 23.0% - 25.0%), FeP21 (P 20.0% - 23.0%), FeP18 (P 17.0% - 20.0%) thiab FeP16 (P 15.0% - 17.0%). Tsis tas li ntawd, raws li cov qauv tsim nyog, nws tuaj yeem muab faib ua 6 qib raws li cov ntsiab lus phosphorus sib txawv thiab cov ntsiab lus tsis huv.

Qib FeP24 (P 23.0% - 25.0%)

Hauv FeP24 qib ferropho sphorus alloys, cov ntsiab lus phosphorus yog nyob rau theem siab, nyob rau hauv thaj tsam ntawm 23.0% - 25.0%. Cov ntsiab lus phosphorus siab muab qib no ntawm ferrophosphorus alloys tshwj xeeb zoo hauv qee qhov kev thov nrog cov phosphorus siab. Piv txwv li, hauv kev ua kom zoo ntawm qee cov qib steel tshwj xeeb, cov ntsiab lus phosphorus ntau dua tuaj yeem txhim kho lub zog ntawm cov hlau thiab txhim kho nws cov kev tiv thaiv corrosion rau qee yam. Nyob rau tib lub sijhawm, vim muaj cov phosphorus, lub machinability ntawm cov hlau tuaj yeem txhim kho. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias cov ntsiab lus phosphorus ntau dhau kuj tseem yuav ua rau cov hlau tsis muaj zog, yog li tus nqi ntxiv yuav tsum tau tswj nruj me ntsis thaum siv. Ntxiv rau ob lub ntsiab lus tseem ceeb ntawm phosphorus thiab hlau, qib no ntawm cov hlau phosphorus alloy tseem muaj me me ntawm impurities xws li silicon, manganese, carbon, thiab sulfur. Cov ntsiab lus silicon feem ntau yog nyob rau hauv thaj tsam ntawm 0.1% - 6%. Cov khoom siv silicon tuaj yeem ua lub luag haujlwm deoxidation hauv cov hlau, uas pab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau.

Qib FeP21 (P 20.0% - 23.0%)

FeP21 qib ferrophosphorus alloy muaj cov ntsiab lus phosphorus qis dua li FeP24 qib, xws li 20.0% mus rau 23.0%. Qhov sib txawv ntawm cov ntsiab lus phosphorus no ua rau qib ntawm ferrophosphorus alloy txawv ntawm qib FeP24 raws li kev ua tau zoo thiab kev siv. Qee lub sij hawm qhov xav tau cov ntsiab lus phosphorus tsawg, tab sis phosphorus xav tau los ua lub luag haujlwm tshwj xeeb, FeP21 qib ferro phosphorus alloy tuaj yeem ua tau raws li qhov xav tau. Piv txwv li, hauv kev tsim cov hlau cam khwb cia zoo ib yam, qhov tsim nyog ntawm phosphorus tuaj yeem txhim kho cov dej ntws ntawm cov hlau molten, yog li txhim kho kev ua haujlwm thiab qhov zoo ntawm castings. Nyob rau hauv cov ntsiab lus ntawm impurity cov ntsiab lus, cov ntsiab lus ntawm impurities xws li silicon, manganese, carbon, thiab sulfur yog roughly nyob rau hauv ib tug zoo xws li cov qib FeP24, tab sis cov ntsiab lus tshwj xeeb yuav txawv me ntsis vim txawv ntau lawm txheej txheem thiab raw khoom.

FeP18 qib (P 17.0% - 20.0%)

FeP18 qib ferrophosphorus alloy muaj phosphorus cov ntsiab lus nyob rau hauv thaj tsam ntawm 17.0% - 20.0%. Qib no ntawm ferrophosphorus alloy muaj qhov tshwj xeeb zoo hauv qee qhov kev thov. Piv txwv li, thaum tsim ib co steels uas yuav tsum tau ib tug sib npaug ntawm lub zog thiab toughness, no qib ntawm ferrophosphorus alloy yuav siv tau raws li ib tug haum additive. Vim tias nws cov ntsiab lus phosphorus nruab nrab, nws tuaj yeem tsis tsuas yog txhim kho lub zog ntawm cov hlau mus rau qee qhov, tab sis kuj yuav tsis ua kom cov brittleness zoo li cov alloys siab phosphorus cov ntsiab lus, yog li xyuas kom meej tias cov hlau muaj kev ua tau zoo. Hais txog impurity muaj pes tsawg leeg, nws kuj muaj cov impurities xws li silicon, manganese, carbon, thiab sulfur. Lawv lub xub ntiag kuj muaj qee yam cuam tshuam rau kev ua haujlwm ntawm cov hlau. Piv txwv li, manganese tuaj yeem ua lub luag haujlwm hauv desulfurization thiab ntxiv dag zog. cov

FeP16 qib (P 15.0% - 17.0%)

FeP16 qib ferrophosphorus alloy muaj cov ntsiab lus phosphorus tsawg, ntawm 15.0% - 17.0%. Cov ntsiab lus phosphorus qis ua rau qib no ntawm ferrophosphorus alloy ua lub luag haujlwm hauv qee qhov kev siv nrog kev txwv nruj ntawm cov ntsiab lus phosphorus. Piv txwv li, nyob rau hauv zus tau tej cov steels tshwj xeeb uas tsis tshua muaj yuav tsum tau rau steel brittleness, nws yog tsim nyog los siv FeP16 qib ferrophosphorus alloy nrog cov ntsiab lus phosphorus tsawg los xyuas kom meej tias cov hlau muaj lub zog zoo thaum tsis muaj teeb meem brittleness vim phosphorus ntau dhau. Nws cov ntsiab lus impurity kuj ua raws li cov kev cai dav dav ntawm ferrophosphorus alloys, muaj me me ntawm silicon, manganese, carbon, sulfur, thiab lwm yam.

Qhov sib txawv ntawm qhov sib txawv ntawm cov qib sib txawv ntawm ferrophosphorus alloys ua rau muaj qhov sib txawv tseem ceeb hauv lawv qhov kev ua tau zoo thiab kev siv cov xwm txheej.FeP24 qib alloysnrog cov ntsiab lus phosphorus siab feem ntau yog siv los tsim qee cov hlau tshwj xeeb uas muaj lub zog siab thiab siab corrosion kuj yuav tsum tau vim lawv lub zog siab thiab zoo corrosion kuj, xws li hauv kev tsim khoom ntawm qee qhov marine engineering steels thiab cov cuab yeej siv tshuaj.FeP16 qib alloysnrog cov ntsiab lus tsis tshua muaj phosphorus yog qhov tsim nyog rau kev tsim cov hlau uas yuav tsum tau muaj zog heev, xws li kev ua kom zoo ntawm cov hlau rau qee qhov hauv thaj chaw aerospace, vim tias lawv muaj tsawg dua ntawm brittleness. Hauv kev lag luam casting, qib sib txawv ntawm ferrophosphorus alloys kuj muaj cov kev siv sib txawv. Piv txwv li,FeP21 lossis FeP18 qib alloysnrog cov ntsiab lus phosphorus nruab nrab tuaj yeem txhim kho qhov fluidity ntawm cov hlau molten thiab tau siv dav hauv kev tsim cov hlau cam khwb cia zoo tib yam thiab hnav- cov khoom cam khwb cia hlau. Lawv tuaj yeem siv los tsim tsheb lub tog raj kheej liners, lub cav chais, tsheb ciav hlau nres khau thiab lwm qhov chaw los txhim kho corrosion kuj thiab hnav tsis kam ntawm cov khoom siv tshuab. cov

Hauv cov ntsiab lus, qhov sib txawv ntawm cov qib sib txawv ntawm ferrophosphorus alloys, tshwj xeeb tshaj yog qhov sib txawv ntawm cov ntsiab lus phosphorus thiab impurity cov ntsiab lus, ua rau lawv muaj lawv tus kheej cov yam ntxwv ntawm kev ua tau zoo, yog li ua lub luag haujlwm tseem ceeb hauv kev lag luam sib txawv thiab daim ntawv thov scenarios. Kev nkag siab txog qhov sib txawv ntawm qhov sib txawv thiab lawv cov kev ua tau zoo thiab kev siv yog qhov tseem ceeb heev rau kev xaiv thiab siv cov ferrophosphorus alloys.
