Phosphorus hlau FeP18 Granules

Phosphorus hlausiv nyob rau hauv steelmaking yog tsuas yog siv los ua kom cov phosphorus cov ntsiab lus nyob rau hauv molten steel, thiab cov resulting hlau muaj zoo txiav zog. Txoj kev tau txais ferrophosphorus feem ntau yog los ntawm phosphorus-smelting hluav taws xob rauv, uas cov ntsiab lus phosphorus yog 20 ~ 26%. Raws li tus neeg sawv cev alloying hauv kev lag luam steelmaking, nws tuaj yeem tsim phosphates.

Muaj ob hom phosphorus hlau tsim nyob rau hauv kuv lub teb chaws, FeP1 thiab FeP2, muaj 15-20% phosphorus. atomic tooj ntawm phosphorus yog 15, atomic hnyav yog 30.97, cov txheej txheem hluav taws xob sab nraud yog 3S3P, thiab qhov ceev yog 1.83g / cm3 (dawb phosphorus) 2.2g / cm3 (Liab phosphorus), melting point 44 degree, 7 boiling point 25. degree, muaj phosphides xws li Fe3P, Fe2P, FeP, FeP2, thiab lwm yam., muaj 18% ~ 25% phosphorus hlau, melting kub ntau yam 1100 ~ 1250 degree, ceev 5.8 ~ 6.5g / cm3.

Ntau tus kws tshaj lij steelmaking hu ua ferrophosphorus yog "tsis tseem ceeb" ferroalloy khoom hauv steelmaking. Nws tuaj yeem txhim kho qhov fluidity ntawm molten hlau. Thaum siv, phosphorus cov ntsiab lus Performance index yuav tsum nruj me ntsis tswj kom ntseeg tau tias phosphorus hlau yog hnav-resistant thiab nkig, thiab txhim kho tag nrho cov hnav tsis kam.

Cov ntsiab lus phosphorus yog li ntawm 0.15%, uas tuaj yeem txhim kho qhov hnav tsis kam ntawm cov hlau cam khwb cia, ua kom lub zog tensile ntawm cov hlau, txhim kho kev ua tau zoo thiab qhov zoo ntawm cov castings, txhim kho thermal conductivity thiab kub ua hauj, thiab zoo. txhim kho kev faib network ntawm phosphorus eutectic hauv castings. Qhov zoo tshaj plaws thermal conductivity thiab kub tsis kam ua rau lub ntsej muag hnav tsis zoo thiab tsis tshua muaj peev xwm tsim cov txim taws thaum sib txhuam. Nws tuaj yeem pom tias ferrophosphorus ua lub luag haujlwm zoo hauv kev tsim steel. Nws tsis yog qhov xav tsis thoob tias cov kws tshaj lij hu nws yog ib qho tseem ceeb ntawm cov khoom smelting rau steelmaking.
