Ferro phosphorus siv dab tsi?

Ferrro phosphorus (FEP) yog FERROALLOYALLY SIV RAU OB LUB HOM PHIAJ RAU OB METALLURGY: Raws li APhosphorus additiveThiab raws li aDeoxidizerCov. Nws cov ntawv thov muaj ntau dua nicho tshaj li alloys zoo li ferrosilicon lossis ferromanganese.

​1. Raws li ib tug phosphorus additive:​

Nov yog thawj lub luag haujlwm. Phosphorus tau ntxiv rau qee yam metrals rau impart cov khoom tshwj xeeb:

•​Hauv Hlau:Phosphorus tau ntxiv rau hauv cov nyiaj me, tswj hwm (feem ntau<0.12%) to certain ​Dawb -} Txiav Hlau(Kuj tseem hu ua Dawb - tshuab xaws hlau). Nws txhim kho machinity los ntawm nce brittleness hauv nti, tso cai rau kev txiav cov tshuaj ntxuav kom huv thiab nrawm dua tshuab ceev. Nws yuav tsum tau ua tib zoo tswj hwm, raws li ntau tshaj phosphorus ua rau feem ntau ntawm cov hlau loj heev (cov nyhuv hu ua "luv luv").

•​Hauv cov hlau nrum:Phosphorus txhim kho covDej txhawvNtawm Molten nrum hlau. Qhov no tso cai rau nws sau cov pwm sib xyaw ua ke yooj yim dua, ua rau nws muaj nuj nqis rau kev tsim cov ncauj lus kom ntxaws. Nws kuj tseem nce cov hnav tsis kam thiab tawv ntawm qhov kawg hlau cov khoom lag luam.

​2. Raws li deoxidizer:​

Cov phosphorus hauv FEP muaj kev sib txawv siab rau cov pa oxygen. Thaum ntxiv rau Molten hlau, nws pab tshem tawm cov pa oxygen, ua rau lub huv si, siab dua steel lossis hlau nrog cov oxide tsawg dua.

​3. Lwm Yam Siv:​

•Zus tau cov siab - muaj zog tsawg -} alloy (hsla) hlau:Hauv cov qhab nia tshwj xeeb heev, nws tuaj yeem siv los ua cov neeg sawv cev muaj zog.

•​Cov khoom siv raw rau tshuaj:Nws tuaj yeem raug siv los ua lub hauv paus ntawm phosphorus rau kev tsim cov khoom siv phosphorus, txawm tias qhov no tsis tshua muaj.

Dab tsi yog cov mis rau ferro phosphorus?

Tsis zoo li cov tshuaj sib xyaw ua ke nrog cov sib piv ruaj khov (piv txwv li, h₂o), ferro phosphorus yog ib qhoHlauHlau (FE) thiab phosphorus (p). Yog li ntawd, nws tsis muaj ib qho tshuaj tas tib yam tshuaj.

Nws yog hloov txhais los ntawm nwsSib xyaw ntau, Uas yog qauv rau cov qib kev lag luam.

Feem ntau cov qib yogFerro Phosphorus 25, Uas muaj cov yeeb yaj kiab hauv qab no:

•Phosphorus (p):​ ~25%

•Hlau (FE):~ 70-74% (tshuav)

•​Impurities:Cov tseem tshuav muaj cov ntsiab lus xws li silicon (si), manganese (mn), thiab carbon (c) los ntawm cov txheej txheem ntau lawm.

Koj kuj tseem tuaj yeem pom lwm qib ntxiv, xws li FEP16 lossis FEP30, uas tus lej uas tau hais txog cov feem pua ​​uas yog ntawm phosphorus.

​Hauv cov ntsiab lus:Thaum koj tuaj yeem sawv cev nws feem ntauTus FEP, Nws yog qhov tseeb dua los xav txog nws raws li kev sib xyaw ntawmFe + P, Nrog phosphorus ntsiab lus ib puag ncig​25%​Cov. Nws yog ib qho tseem ceeb, tshwj xeeb ntxiv rau kev txhim kho cov tshuab luam ntawv ntawm cov hlau thiab dej fluidity ntawm cam khwb cia hlau.
