piav qhia ntawm ferro phosphorus
Ferrophosphorusyog tau los ntawm phosphorus-ua hluav taws xob rauv. Nws yog ib qho symbiotic compound uas muaj 20-26% phosphorus thiab 0.1-6% silicon, uas tuaj yeem hloov kho corrosion thiab chipping zog ntawm hlau. Ferrophosphorus yog siv los ua tus neeg sawv cev alloying hauv kev lag luam steel thiab tuaj yeem tsim cov phosphates.
Cov yam ntxwv ntawm ferrophosphorus
Ferrophosphorus tuaj yeem hnov mob nrog cov ntsiab lus xws li oxygen thiab sulfur thiab tuaj yeem tsim cov alloys nrog lwm cov hlau hauv qee yam mob. Lub melting kub ntau yam ntawm hlau muaj 18% mus rau 25% phosphorus yog 1100 ~ 1250 degree, thiab qhov ceev yog 5.8 ~ 6.5g / cm3.

Kev siv ferrophosphorus
Ntxiv phosphorus rau qee hom hlau tuaj yeem txhim kho lub zog, kev tiv thaiv corrosion, thiab kev ua haujlwm ntawm cov hlau, tab sis nws kuj ua rau cov hlau tsis muaj zog. Ntxiv phosphorus rau cam khwb cia hlau tuaj yeem txhim kho qhov fluidity ntawm molten hlau, yog li txhim kho kev ua tau zoo thiab nto zoo ntawm castings; grey cam khwb cia hlau muaj 0.5% phosphorus, uas tuaj yeem txhim kho nws lub zog tensile.
Ferrophosphorous yog cov khoom siv ntau yam uas nws daim ntawv thov hauv ntau qhov chaw ua haujlwm tau zoo txhim kho cov khoom ua haujlwm thiab ua haujlwm ntev. Ferrophosphorous yog dav siv hauv kev ua liaj ua teb, khoom noj khoom haus additives, roj teeb tsim, thiab lwm yam kev lag luam.
Kev tsim cov ferrophosphorus
Ferrophosphorus yog tsim los ntawm kev txo apatite nrog carbon ntawm qhov kub thiab txias. Silica yog ntxiv rau daim ntawv calcium silicate. Ntxiv steel scraps thiab rov qab ua tus thawj apatite. Silica yog ntxiv rau daim ntawv calcium silicate. Ntxiv steel scraps thiab txo phosphorus los tsim Fe2P.
