Cov Khoom Duab
1.Keeb kwm ntawmferro phosphorus: Nyob rau hauv 1669 Hom pom phosphorus. Xyoo 1826, Bertier tsim cov hlau phosphorus. Nyob rau hauv 1868, Bryson patented zus tau tej cov phosphorus thiab phosphoric acid los ntawm lub moj tej tawg rauv. Xyoo 1929, qhov cub tawg rau kev tsim cov thermal phosphoric acid hauv Victor tau muab tso rau hauv kev ua haujlwm. Nyob rau hauv lub 70s ntawm lub xyoo pua puv 19, patents rau smelting ntawm phosphorus thiab ferrophosphorus los ntawm hluav taws xob furnaces tau tshwm sim. Xyoo 1925, thawj 3, 000 kW peb-theem hluav taws xob rauv tau tsim hauv Bitfield los tsim phosphorus. Tom qab ntawd, lub cub hluav taws xob tau los ua cov cuab yeej tseem ceeb rau kev tsim cov phosphorus.
2.Kev siv ntawmferro phosphorus: Ferrophosphorus yog cov hlau tshwj xeeb heev vim tias phosphorus yog qhov tsis zoo rau cov hlau feem ntau. Tab sis qee zaum nws muaj nws lub luag haujlwm tshwj xeeb. Piv txwv li, qhov sib ntxiv ntawm phosphorus rau qee qib steel tuaj yeem txhim kho lub zog, corrosion resistance thiab machinability ntawm cov hlau, tab sis ua rau kom cov nkig ntawm cov hlau. Qhov sib ntxiv ntawm phosphorus rau cam khwb cia hlau tuaj yeem txhim kho cov dej ntws ntawm cov hlau molten, yog li txhim kho qhov kev ua tau zoo thiab qhov zoo ntawm cov castings, thiab lub zog tensile ntawm grey cam khwb cia hlau tuaj yeem txhim kho los ntawm kev muaj {{0}}.5% phosphorus. Hnav-resistant cam khwb cia hlau muaj txog 0.15% phosphorus, uas tuaj yeem txhim kho nws cov hnav tsis kam.
3.Covferro phosphoruscov ntsiab lus ntawm lub tsheb ciav hlau nres khau yog {{0}}.7% ~ 1.0%, thiab cov qauv binary phosphorus eutectic yog tsim nyob rau hauv lub casting, thiab nws yog faib nyob rau hauv ib tug network. Lub siab hardness ntawm phosphorus eutectic tsis tsuas yog txhim kho nws cov hnav tsis kam, tab sis kuj txhim kho thermal conductivity thiab kub tsis kam. Cov khaub ncaws hnav yog qhov sib xws, thiab nws tsis yooj yim los tsim sparks thaum txhuam. Hlau phosphorus uas muaj 20% phosphorus yog hauv av rau hauv cov hmoov ultra-nplua, uas tuaj yeem hloov ultra-fine zinc hmoov li txheej. Hlau phosphorus kuj yog ib yam khoom tiv thaiv hluav taws xob hluav taws xob
