I-Ferrosilicon iyi-ferroalloy eyakhiwe ngensimbi ne-silicon.I-Ferrosilicon iyingxubevange ye-iron-silicon eyenziwe ngokuncibilikisa i-coke, i-steel shavings, ne-quartz (noma i-silica) esithandweni sikagesi.Njengoba i-silicon nomoya-mpilo kuhlanganiswe kalula ku-silicon dioxide, i-ferrosilicon ivame ukusetshenziswa njenge-deoxidizer ekwenzeni insimbi.Ngesikhathi esifanayo, ngenxa yokuthi i-SiO2 ikhiqiza ukushisa okuningi, kuyazuzisa futhi ukukhulisa izinga lokushisa lensimbi encibilikisiwe ngesikhathi sokukhishwa kwe-deoxidation.Ngasikhathi sinye, i-ferrosilicon ingasetshenziswa futhi njengesengezo se-alloying element, futhi isetshenziswa kabanzi kunsimbi yesakhiwo se-alloy ephansi, insimbi yasentwasahlobo, insimbi enensimbi, insimbi engashisi kanye nensimbi kagesi ye-silicon.I-Ferrosilicon ivame ukusetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni i-ferroalloy kanye nomkhakha wamakhemikhali.
I-Ferroalloy eyakhiwe ngensimbi ne-silicon (isebenzisa i-silica, insimbi, ne-coke njengezinto zokusetshenziswa, i-silicon eyehliswa ekushiseni okuphezulu kwama-degrees angu-1500-1800 incibilika ngensimbi encibilikisiwe ukuze yakhe ingxube ye-ferrosilicon).Iwuhlobo olubalulekile lwengxubevange embonini yokuncibilikisa.
Incazelo yomkhiqizo
(1) Isetshenziswa njenge-deoxidizer kanye nama-alloying agents embonini yensimbi.Ukuze uthole ukwakheka kwamakhemikhali afanelekile futhi uqinisekise ikhwalithi yensimbi, esigabeni sokugcina sensimbi kufanele ikhishwe i-deoxidized.Ukuhlobana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kukhulu kakhulu, Ngakho-ke i-ferrosilicon iyi-deoxi- dizer eqinile esetshenziselwa ukukhishwa kwe-sedimentation kanye ne-diffusion deoxidation yokwenza insimbi.Engeza inani elithile le-silicon ensimbi, ingathuthukisa kakhulu amandla, ubulukhuni kanye nokunwebeka kwensimbi.
(2) Isetshenziswa njenge-nucleating ejenti kanye ne-spheroidizing embonini yensimbi.I-Cast iron iwuhlobo lwensimbi ebalulekile yesimanje yezimboni, Ishibhe kakhulu kunensimbi, ukuncibilika kalula ukucwengisiswa, ngokusebenza okuhle kakhulu kokulingisa kanye namandla okuzamazama komhlaba kungcono kakhulu kunensimbi.Ikakhulukazi insimbi eyi-nodular cast iron, Izakhiwo zayo zemishini endaweni noma eduze kwezakhiwo zensimbi.Engeza inani elithile le-silicon kunsimbi ekhonjiwe kungavimbela insimbi ekwakhekeni, kukhuthaze ukuna kwe-graphite ne-carbide spheroidizing.Ngakho-ke ekukhiqizeni insimbi yama-nodular, i-ferrosilicon iwuhlobo lwezijovo ezibalulekile (Siza ukuhlukanisa i-graphite) kanye ne-spheroidizing agent.
