Kev soj ntsuam ntawm lub cev muaj zog ntawm ferrosilicon alloy:
Ntshiab silicon yog hlau grey, cov khoom siv crystalline nrog lub ntsej muag zoo nkauj, tawv thiab nkig, thiab tsis yog hlau. Lub atomic hnyav ntawm silicon yog 28.08. , ntom 2300kg / m3, melting point 1535k.
Silicon thiab hlau tuaj yeem yaj ib leeg hauv ib qho kev faib ua feem thiab tuaj yeem tsim cov silicides xws li fesi2, fesi fe5si3 fe2si, ntawm cov ntawv tshiab fesi muaj nyob rau hauv cov kua alloy, thiab cov silicides ntxiv tuaj yeem decompose nyob rau hauv lub xeev khoom thaum rhuab.
Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon. Lub melting point ntawm ferrosilicon nce raws li cov ntsiab lus silicon nce, thiab lub melting point ntawm tus qauv ferrosilicon yog qis dua 1643k.
Cov hlau nplaum ntawm silicon thiab hlau yog feem ntau sib cais, thiab qhov sib txawv ntawm cov ntsiab lus silicon nyob rau sab sauv ntawm cov hlau ingot thiab cov ntsiab lus silicon hauv qab yog ntau tshaj 20%. Qhov ntau dua qhov tuab ntawm alloy ingot thiab lub sijhawm txias txias, qhov sib cais yuav hnyav dua.
Ferrosilicon cov khoom yuav pulverize. Qhov no yog vim ferrosilicon uas muaj cov impurities xws li phosphorus, aluminium thiab calcium yog khaws cia rau hauv qhov chaw ntub dej, ua rau pulverization thiab tso tawm cov pa phem.
Deoxidizer thiab alloy txias txias rau steelmaking; siv los ua inoculant hauv casting.
