Ferrosilicon 45 # yog ua haujlwm hauv kev lag luam steel ua ob qho tib si deoxidiser thiab tus neeg sawv cev alloying. Txhawm rau lav qhov zoo ntawm cov hlau thiab ua tiav cov tshuaj lom neeg xav tau, deoxidation yuav tsum ua kom tiav nyob rau theem kawg ntawm kev tsim steel. Vim muaj cov tshuaj lom neeg muaj zog ntawm silicon thiab oxygen, ferrosilicon yog ib qho zoo deoxidiser rau steelmaking, siv rau nag lossis daus thiab diffusion deoxidation. Qhov sib ntxiv ntawm ib qho tshwj xeeb ntawm silicon rau hlau tuaj yeem txhim kho nws lub zog, hardness thiab elasticity. Yog li ntawd, ferrosilicon yog ua hauj lwm raws li ib tug alloying neeg sawv cev nyob rau hauv lub smelting ntawm cov qauv steel (muaj 0.40-1.75% silicon), cov cuab yeej steel (muaj 0.30-1. 8% Si), caij nplooj ntoos hlav steel (muaj 0 40-2.8% Si) thiab silicon steel rau transformers (muaj 2.81-4.8% Si). Tsis tas li ntawd, ferrosilicon hmoov feem ntau yog siv los ua cov cua kub hauv lub hau ntawm cov hlau ingots los txhim kho qhov zoo thiab rov qab tus nqi ntawm cov hlau ingots, peev ntawm nws lub peev xwm los tso tawm ntau cov cua sov thaum kub kub.
Ferrosilicon yog ua haujlwm raws li inoculant thiab spheroidiser hauv kev lag luam cam khwb cia hlau. Cam khwb cia hlau yog ib qho tseem ceeb ntawm cov khoom siv hlau nyob rau hauv niaj hnub kev lag luam toj roob hauv pes. Nws yog ib qho txiaj ntsig zoo rau cov hlau, muab kev sib tw ncaj nraim thiab smelting, superior casting zog thiab txhim kho kev poob siab piv rau cov hlau. Tshwj xeeb, cov hlau nplaum muaj cov khoom siv kho tshuab uas sib npaug los yog ze rau cov hlau. Qhov sib ntxiv ntawm ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau thiab txhawb cov nag lossis daus thiab spheroidisation ntawm graphite. Yog li ntawd, ferrosilicon yog ib qho tseem ceeb inoculant (los pab precipitate graphite) thiab spheroidiser nyob rau hauv zus tau tej cov ductile hlau.
