Ferrosilicon ni ferroalloy igizwe nicyuma na silikoni.Ferrosilicon ni umusemburo w'icyuma-silikoni ikozwe mu gushonga kokiya, kogosha ibyuma, na quartz (cyangwa silika) mu itanura ry'amashanyarazi.Kubera ko silikoni na ogisijeni byahujwe byoroshye na dioxyde de silicon, ferrosilicon ikoreshwa nka deoxidizer mugukora ibyuma.Muri icyo gihe, kubera ko SiO2 itanga ubushyuhe bwinshi, ni byiza kandi kongera ubushyuhe bwibyuma bishongeshejwe mugihe cya deoxidation.Muri icyo gihe, ferrosilicon irashobora kandi gukoreshwa nk'inyongeramusaruro ivanze, kandi ikoreshwa cyane mubyuma bito bito byubatswe, ibyuma byamasoko, bitwaje ibyuma, ibyuma birwanya ubushyuhe hamwe nicyuma cya silikoni.Ferrosilicon ikunze gukoreshwa nkibintu bigabanya umusaruro wa ferroalloy ninganda zikora imiti.
Ferroalloy igizwe nicyuma na silikoni (ukoresheje silika, ibyuma, na kokiya nkibikoresho fatizo, silikoni yagabanutse ku bushyuhe bwo hejuru bwa dogere 1500-1800 ishonga mu cyuma gishongeshejwe kugirango ikore ferrosilicon).Nubwoko butandukanye bwingirakamaro mu nganda zashonga.
Ibisobanuro ku bicuruzwa
(1) Ikoreshwa nka deoxidizer na alloying agent mu nganda zibyuma.Kugirango ubone imiti yujuje ibyangombwa kandi yemeze ubwiza bwibyuma, mugice cyanyuma cyicyuma kigomba kwangirika.Imiti iri hagati ya silicon na ogisijeni ni nini cyane, Gutyo ferrosilicon ni deoxi- dizer ikomeye ikoreshwa mubutayu no gukwirakwiza deoxidisation yo gukora ibyuma.Ongeramo umubare runaka wa silicon mubyuma, birashobora kuzamura cyane imbaraga, ubukana nubworoherane bwibyuma.
(2) Ikoreshwa nka nucleating agent na spheroidizing agent munganda zicyuma.Ibyuma byuma ni ubwoko bwibikoresho byinganda bigezweho is Birahendutse cyane kuruta ibyuma, byoroshye gushonga gutunganya, hamwe nibikorwa byiza bya casting hamwe nubushobozi bwa seisimike nibyiza cyane kuruta ibyuma.Cyane cyane icyuma cya nodular, Icyuma cyacyo cyangwa hafi yimiterere yicyuma.Ongeramo umubare munini wa silikoni mucyuma gishobora gukumira icyuma gukora, guteza imbere imvura ya grafite na karbide spheroidizing.Rero, mubyuma bya nodular, ferrosilicon nubwoko bwingirakamaro (Ifasha gutandukanya grafite) hamwe na spheroidizing agent.
