piav qhia ntawm ferro phosphorus
Ferrophosphorusyog ib qho alloy ntawm hlau thiab phosphorus. Ferrophosphorus yog ib tug byproduct ntawm phosphorus ntau lawm nyob rau hauv submerged-arc furnaces los ntawm apatites, los ntawm lawv txo nrog carbon. Nws yog tsim los ntawm cov hlau oxide impurities.
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 cov hlau uas 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 tsim cov ferrophosphorus
Kev npaj tshuaj ferrophosphorus feem ntau siv cov tshuaj reactants xws li hydroxides thiab acids. Cov kauj ruam tshwj xeeb yog raws li nram no:
1. Ua ntej, yaj ib qhov tsim nyog ntawm hydroxide hauv dej los tsim hydroxide ions.
2. Ntxiv cov kua qaub uas tsim nyog rau cov tshuaj thiab ua rau cov hydroxide ions ua kom muaj dej thiab cov ntsev sib xws.
3. Qhuav cov ntsev tau txais cov khoom ferrophosphorus.
