I-Ferrosilicon yi-ferroalloy eyenziwe ngentsimbi kunye ne-silicon. I-Ferrosilicon yi-alloy ye-iron-silicon eyenziwe ngokunyibilikisa i-coke, i-shavings yensimbi, kunye ne-quartz (okanye i-silica) kwiziko lombane. Ekubeni i-silicon kunye ne-oksijini zidityaniswa ngokulula kwi-silicon dioxide, i-ferrosilicon isoloko isetyenziswa njenge-deoxidizer kwi-steelmaking. Kwangaxeshanye, kuba iSiO2 ivelisa ubushushu obuninzi, kukwaluncedo nokwandisa ubushushu bentsimbi enyibilikisiweyo ngexesha lokudityaniswa kwe-deoxidation. Kwangaxeshanye, i-ferrosilicon inokusetyenziswa njenge-alloying element additive, kwaye isetyenziswa ngokubanzi kwi-low alloy structural iron, intsimbi yasentwasahlobo, intsimbi yokuthwala, intsimbi enganyangekiyo kubushushu kunye nentsimbi yombane yesilicon. I-Ferrosilicon isoloko isetyenziswa njenge-arhente yokunciphisa kwimveliso ye-ferroalloy kunye neshishini lemichiza.
I-Ferroalloy eyenziwe ngentsimbi kunye ne-silicon (usebenzisa i-silica, insimbi, kunye ne-coke njengezinto eziluhlaza, i-silicon eye yancitshiswa kwiqondo lokushisa eliphezulu le-1500-1800 degrees inyibilika kwintsimbi etyhidiweyo ukwenza i-ferrosilicon alloy). Ludidi olubalulekileyo lwealloyi kwishishini lokunyibilikisa.
Ingcaciso yeMveliso
(1) Isetyenziswe njenge-deoxidizer kunye ne-alloying agents kwishishini lensimbi. Ukuze ufumane ukubunjwa kweekhemikhali ezifanelekileyo kunye nokuqinisekisa umgangatho wensimbi, kwinqanaba lokugqibela lensimbi kufuneka libe ne-deoxidized. Ubudlelwane bekhemikhali phakathi kwesilicon kunye neoksijini inkulu kakhulu, kungoko i-ferrosilicon iyi-deoxidizer eyomeleleyo esetyenziswa kwintlenga kunye ne-diffusion deoxidation yokwenza intsimbi. Yongeza inani elithile le-silicon kwintsimbi, inokuphucula kakhulu amandla, ukuqina kunye nokuqina kwentsimbi.
(2) Isetyenziswe njenge-agent ye-nucleating kunye ne-agent ye-spheroidizing kwishishini lentsimbi. Intsimbi yokuphosa luhlobo lwemathiriyeli yesinyithi yanamhlanje ebalulekileyo, Ixabiso eliphantsi kakhulu kunentsimbi, ukunyibilika ngokulula ukusulungekiswa, ngokusebenza okugqwesileyo kokusa kunye nomthamo wenyikima ungcono kakhulu kunentsimbi. Ngokukodwa i-nodular cast iron, iipropathi zayo zoomatshini kwindawo okanye kufutshane neempawu zentsimbi. Yongeza inani elithile le-silicon kwintsimbi etyhidiweyo inokuthintela isinyithi ekubunjweni, ukukhuthaza imvula ye-graphite kunye ne-carbide spheroidizing. Ngaloo ndlela kwimveliso yentsimbi ye-nodular, i-ferrosilicon luhlobo lwe-inoculants ebalulekileyo (Uncedo lwahlula i-graphite) kunye ne-agent ye-spheroidizing.
