Ukukhiqizwa kanye nokusetshenziswa kwe-ferrosilicon

1. Ukukhiqizwa kwe-ferrosilicon

I-Ferrosilicon iyingxube yensimbi eyakhiwe ngensimbi ne-silicon.I-Ferrosilicon iyingxubevange ye-iron-silicon eyenziwe nge-coke, izinsalela zensimbi, i-quartz (noma i-silica) njengezinto zokusetshenziswa futhi incibilikiswa esithandweni sikagesi.Njengoba i-silicon nomoya-mpilo kuhlangana kalula ukwenza i-silica, i-ferrosilicon ivame ukusetshenziswa njenge-deoxidizer ekwenzeni insimbi.Ngesikhathi esifanayo, njengoba i-SiO2 ikhulula inani elikhulu lokushisa lapho ikhiqizwa, kuyasiza futhi ukukhulisa izinga lokushisa lensimbi encibilikisiwe ngenkathi i-deoxidizing.Ngesikhathi esifanayo, i-ferrosilicon ingasetshenziswa futhi njengesengezo se-alloying element futhi isetshenziswa kabanzi kunsimbi yesakhiwo esinengxubevange 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.

2. Ukusetshenziswa kwe-ferrosilicon

I-Ferrosilicon isetshenziswa kabanzi embonini yensimbi, embonini yokuphonsa kanye nokunye ukukhiqizwa kwezimboni.

I-Ferrosilicon iyi-deoxidizer ebalulekile embonini yokwenza insimbi.Ensimbi ye-torch, i-ferrosilicon isetshenziselwa i-deoxidation yemvula kanye ne-diffusion deoxidation.Insimbi yezitini iphinde isetshenziswe njenge-alloying ejenti ekwenzeni insimbi.Ukwengeza inani elithile le-silicon ensimbi kungathuthukisa kakhulu amandla, ubulukhuni kanye nokunwebeka kwensimbi, kuthuthukise ukungena kwensimbi, futhi kunciphise ukulahleka kwe-hysteresis yensimbi ye-transformer.Insimbi ejwayelekile iqukethe i-silicon engu-0.15% -0.35%, insimbi yesakhiwo iqukethe i-silicon engu-0.40% -1.75%, insimbi yensimbi iqukethe i-silicon engu-0.30% -1.80%, insimbi yasentwasahlobo iqukethe i-silicon engu-0.40% -2.80%, insimbi engagqwali engamelana ne-asidi. iqukethe i-silicon engu-3.40% -4.00%, futhi insimbi ekwazi ukumelana nokushisa iqukethe i-silicon engu-1.00% ~ 3.00%.Insimbi ye-silicon iqukethe i-silicon engu-2% kuya ku-3% noma ngaphezulu.

I-silicon ferrosilicon ephezulu noma ama-siliceous alloys asetshenziswa embonini ye-ferroalloy njengama-ejenti anciphisa ukukhiqizwa kwe-carbon ferroalloys ephansi.Ukwengeza i-ferrosilicon ekulahleni insimbi ingasetshenziswa njenge-inoculant ye-nodular cast iron, futhi ingavimbela ukwakheka kwe-carbide, ikhuthaze imvula kanye ne-nodulation ye-graphite, futhi ithuthukise ukusebenza kwe-cast iron.

Ngaphezu kwalokho, i-ferrosilicon powder ingasetshenziswa njengesigaba esimisiwe embonini yokucubungula izimbiwa, futhi njengendawo yokumboza izinduku zokushisela embonini yokukhiqiza induku yokushisela.I-silicon yensimbi ephezulu ingasetshenziswa ukulungisa i-silicon ehlanzekile ye-semiconductor embonini kagesi, futhi ingasetshenziswa ukwenza abicah embonini yamakhemikhali.

Embonini yokwenza insimbi, cishe i-3 ~ 5kG 75% ye-ferrosilicon isetshenziswa ngethani ngalinye lensimbi ekhiqizwayo.
