Ferro Phosphorus yog dab tsi?

Ferrophosphorus hlau (FeP)yog ib qho ferroalloy sib xyaw nrog hlau thiab phosphorus ua nws cov khoom tseem ceeb. Leveraging cov khoom siv ntxiv dag zog thiab cov khoom ua kom zoo ntawm phosphorus, nws tau dhau los ua cov khoom siv tseem ceeb hauv cov hlau, casting, thiab tshuaj lom neeg kev lag luam. Nws cov ntsiab lus phosphorus thiab impurity tswj ncaj qha txiav txim siab qhov ua tau zoo ntawm cov khoom kawg.

Cov yam ntxwv tseem ceeb ntawm ferrophosphorus alloys yog txiav txim los ntawm phosphorus cov ntsiab lus thiab impurity tswj:

 Kev sib xyaw ntau yam:Phosphorus (P) 15% -25% (core functional element), Hlau (Fe) 65% -75%, Impurities Si Less dua los yog sib npaug rau 3.0%, Mn Tsawg dua los yog sib npaug rau 2.5%, C Tsawg dua lossis sib npaug 1.0%, S Tsawg dua lossis sib npaug li 0.5%;
 Core zoo:Tus nqi qis, tseem ceeb ntxiv dag zog; tus nqi ntxiv phosphorus tsuas yog 1/5-1/3 ntawm cov npib tsib xee thiab chromium, haum rau cov khoom loj;
 Tseem ceeb txaus ntshai: Excessive phosphorus content (P>0.06% steel) tuaj yeem yooj yim ua rau txias brittleness, yuav tsum tau tswj nruj ntawm qhov sib ntxiv.

Qhov tshwm sim

Feem ntau nyob rau hauv daim ntawv thaiv, nrog ib tug metallic luster nyob rau saum npoo, thiab cov xim feem ntau yog nyiaj - grey los yog tsaus grey. Qhov loj thiab cov duab ntawm nws cov blocks tuaj yeem sib txawv nyob ntawm cov txheej txheem tsim khoom thiab kev siv tshwj xeeb.

Qhov ntom

The density is relatively high, about 6.3 - 6.7g/cm³, which makes it have a certain sense of weight during use, and when mixed with other materials, it will have different distributions according to the density difference.

Melting point

Lub melting point kuj yog siab, nruab nrab ntawm 1100 - 1300 degree, uas ua rau nws nyob twj ywm nyob rau hauv ib tug kub kub ib puag ncig, haum rau ib co kev lag luam daim ntawv thov uas yuav tsum tau kub resistant cov ntaub ntawv, xws li steelmaking.

Hardness

Lub hardness kuj siab, nrog ib tug Mohs hardness txog 4-5. Qhov hardness no ua rau nws ua tau zoo nyob rau hauv cov nqe lus ntawm hnav tsis kam thiab tuaj yeem tiv taus qee qhov kev sib txhuam thiab kev sib tsoo.

Steelmaking:

Hauv cov txheej txheem steelmaking, ferro phosphorus yog ib qho tseem ceeballoy additive. Qhov tsim nyog ntawm phosphorus tuaj yeem txhim kho lub zog thiab hardness ntawm steel, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov tshwj xeeb alloy steels, xws li siab -lub zog coj-resistant steel thiab corrosion-resistant steel. Nyob rau tib lub sijhawm, phosphorus tuaj yeem txhim kho cov kev ua haujlwm ntawm cov hlau, ua kom yooj yim rau kev txiav hlau thaum lub sijhawm ua haujlwm. Txawm li cas los xij, cov ntsiab lus phosphorus ntau dhau yuav txo qhov toughness ntawm cov hlau thiab yooj yim ua kom txias brittleness, yog li tus nqi ntawm ferrophosphorus ntxiv yuav tsum tau tswj nruj me ntsis.

Casting kev lag luam:

Hauv casting alloys, phosphorus hlau tuaj yeem kho qhov fluidity ntawm cov hlau. Nws tuaj yeem txo cov ntsiab lus melting ntawm cov hlau, ua rau nws yooj yim dua rau cov hlau kom sau cov pwm kab noj hniav thaum lub sij hawm casting txheej txheem, yog li txhim kho cov molding zoo ntawm casting. Thiab nyob rau hauv ib co alloys xws li cam khwb cia tooj liab, ferrophosphorus kuj yog ib qho tseem ceeb additive, uas yuav txhim kho lub koom haum thiab cov khoom ntawm cov alloy thiab txhim kho cov hnav tsis kam thiab corrosion kuj ntawm lub casting.

Lwm yam khoom siv hlau ua:

Hauv qee cov khoom siv hlau tshwj xeeb, hlau phosphorus tuaj yeem siv los tsim phosphorus - muaj cov khoom siv hlau sib xyaw. Cov khoom siv sib xyaw no tuaj yeem ua kom siv tau zoo ntawm cov khoom ntawm ferrophosphorus, xws li lub zog siab, siab hardness thiab zoo hnav tsis kam, thiab tuaj yeem siv los tsim cov hnav- tiv taus thiab corrosion- qhov chaw tiv taus. Tsis tas li ntawd, hauv kev tsim cov khoom siv hlau nplaum, qhov tsim nyog ntawm phosphorus tuaj yeem kho cov khoom sib nqus ntawm cov khoom thiab txhim kho cov hlau nplaum thiab ruaj khov ntawm cov khoom sib nqus.
