Hlau Phosphorus Granules

Ferrophosphateua raws li phosphorus additive hauv steelmaking thiab casting. Phosphorus yog ib qho teeb meem impurity nyob rau hauv feem ntau steel qib, tab sis nws tuaj yeem txhim kho corrosion kuj ntawm qee qib steel.

Thaum siv cov phaj hlau uas muaj phosphorus, adhesion ntawm steel phaj tuaj yeem tiv thaiv. Thaum tsim cov yob, ntxiv 0.4%-0.5% phosphorus tuaj yeem txhim kho fluidity thiab tsis txhob ntog tawg. Phosphorus tuaj yeem txhim kho thiab txhim kho kev ua haujlwm ntawm cov hlau. Cov no yog siv cov ferrophosphorus hauv steelmaking.

Kev siv cov phosphorus hlau hauv casting tuaj yeem txhim kho qhov fluidity ntawm cam khwb cia hlau, yog li txhim kho qhov zoo ntawm castings. Thaum tsim high-phosphorus hnav-resistant cam khwb cia hlau, phosphorus tsim ib tug uniform binary phosphorus eutectic qauv nyob rau hauv lub casting thiab muab faib nyob rau hauv ib tug network. Vim lub siab tawv ntawm phosphorus eutectic, tsheb nres khau muaj 0.7%-1% phosphorus los txhim kho lawv cov hnav tsis kam. Tam sim no, feem ntau siv ferrophosphate yog nyob rau hauv kev lag luam foundry.

Muaj ntau ntau hom phosphorus minerals nyob rau hauv cov xwm, thiab cov ores haum rau industrial ntau lawm mas muaj xws li apatite thiab phosphate pob zeb. Apatite yog cov ntxhia dav dav, thiab cov ntxhia tseem ceeb hauv Hanlin yog fluorapatite. Thoob plaws ntiaj teb, cov peev txheej phosphate pob zeb feem ntau yog muab faib rau hauv Africa, North America, South America, Asia thiab Middle East. Ntau tshaj 80% ntawm phosphate cov peev txheej yog concentrated hauv Morocco thiab Western Sahara, South Africa, Tebchaws Meskas, Tuam Tshoj, Jordan thiab Russia. Tam sim no, kuv lub teb chaws cov khoom tsim tawm txhua xyoo ntawm phosphate pob zeb tshaj 60 lab tons, ntau dua li ntawm cov teb chaws xws li Tebchaws Meskas, Morocco thiab Western Sahara.
