Aikace-aikace na Ferrosilicon

(1) Ana amfani dashi azaman deoxidizer da wakili na alloying a cikin masana'antar ƙera ƙarfe. Domin samun karfe tare da ingantaccen tsarin sinadarai da kuma tabbatar da ingancin karfe, dole ne a aiwatar da deoxidation a matakin karshe na yin karfe. Dangantakar sinadarai tsakanin silicon da oxygen yana da girma sosai, don haka ferrosilicon shine deoxidizer wanda ba makawa a cikin masana'antar ƙera ƙarfe. A cikin samar da karfe, ban da wasu karafa masu tafasa, kusan dukkan nau'ikan karfe suna amfani da ferrosilicon azaman mai ƙarfi deoxidizer don haɓakar hazo da diffusion deoxidation. Ƙara wani adadin siliki zuwa karfe zai iya inganta ƙarfin, taurin da elasticity na karfe. Sabili da haka, ana amfani da shi sosai a cikin ƙwanƙwasa tsarin ƙarfe (wanda ya ƙunshi siO. 40% ~ 1.75%) da kayan aiki na kayan aiki (wanda ya ƙunshi siO. 30%). ~ 1.8%), spring karfe (dauke da Si O. 40% ~ 2.8%) da sauran karfe iri, wani adadin ferrosilicon dole ne a kara a matsayin alloying wakili. Silicon kuma yana da halaye na ƙayyadaddun juriya na musamman, ƙarancin ƙarancin zafi da ƙarfin maganadisu mai ƙarfi. Karfe yana ƙunshe da adadin siliki, wanda zai iya inganta ƙarfin maganadisu na karfe, rage asarar hysteresis, da rage asara na yanzu. Saboda haka, ferrosilicon kuma ana amfani da shi azaman alloying wakili lokacin narke silicon karfe, kamar low silicon karfe ga Motors (dauke da Si O. 80% zuwa 2.80%) da kuma silicon karfe for transformers (dauke da Si 2.81% zuwa 4.8%). amfani.

Bugu da ƙari, a cikin masana'antun ƙarfe, ferrosilicon foda zai iya saki babban adadin zafi lokacin da aka ƙone a yanayin zafi mai yawa kuma ana amfani dashi sau da yawa azaman wakili mai dumama don ƙwanƙolin ƙarfe na ƙarfe don haɓaka inganci da dawo da ƙimar ƙarfe.


(2) Ana amfani dashi azaman inoculant da spheroidizing wakili a cikin masana'antar simintin ƙarfe. Simintin ƙarfe shine muhimmin kayan ƙarfe a masana'antar zamani. Yana da arha fiye da ƙarfe, mai sauƙin narkewa da narkewa, yana da kyawawan kaddarorin simintin gyare-gyare da mafi kyawun juriyar girgizar ƙasa fiye da ƙarfe. Musamman baƙin ƙarfe ductile, kayan aikin injinsa sun isa ko suna kusa da na ƙarfe. yi. Ƙara wani adadin ferrosilicon don jefa baƙin ƙarfe zai iya hana samuwar carbides a cikin baƙin ƙarfe da haɓaka hazo da spheroidization na graphite. Saboda haka, a cikin samar da ductile baƙin ƙarfe, ferrosilicon ne mai muhimmanci inoculant (taimakawa zuwa precipitate graphite) da spheroidizing wakili. .


(3) An yi amfani da shi azaman wakili mai ragewa a samar da ferroalloy. Ba wai kawai alaƙar sinadarai tsakanin silicon da iskar oxygen ta yi girma sosai ba, amma abun cikin carbon na ferrosilicon siliki mai ƙarfi yana da ƙasa sosai. Saboda haka, ferrosilicon high-silicon (ko silicon alloy) ne da aka saba amfani da ragewa wakili a cikin ferroalloy masana'antu a lokacin da samar da low-carbon ferroalloys.
