Menene aikace-aikacen ferrosilicon?

Ferrosilicon, gami da silicon da baƙin ƙarfe, ana samunsa a cikin 45%, 65%, 75% da 90% silicon maki.Amfani da shi yana da faɗi sosai, sannan masana'antar ferrosilicon Anhui Fitech Materials Co., Ltd za ta bincika takamaiman amfaninta daga maki uku masu zuwa.

Da fari dai, ana amfani da shi azaman deoxidizer da wakili na alloying a masana'antar ƙera ƙarfe.Domin samun karfe tare da ingantaccen tsarin sinadarai da tabbatar da ingancin karfe, dole ne a aiwatar da deoxidation a ƙarshen aikin ƙarfe.Dangantakar sinadarai tsakanin silicon da oxygen yana da girma sosai.Saboda haka, ferrosilicon shine mai ƙarfi deoxidizer don yin ƙarfe, wanda ake amfani dashi don hazo da difffusion deoxidation.Ƙara wani nau'i na siliki zuwa karfe zai iya inganta ƙarfin, taurin da elasticity na karfe.
Saboda haka, ferrosilicon kuma ana amfani da shi azaman alloying wakili a lokacin da smelting tsarin karfe (dauke da silicon 0.40-1.75%), kayan aiki karfe (dauke da silicon 0.30-1.8%), spring karfe (dauke da silicon 0.40-2.8%) da silicon karfe for transformer (dauke da siliki). dauke da silicon 2.81-4.8%).

Bugu da ƙari, a cikin masana'antun masana'antun ƙarfe, ferrosilicon foda zai iya saki babban adadin zafi a ƙarƙashin yanayin zafi.Ana amfani dashi sau da yawa azaman wakili na dumama na ingot cap don inganta inganci da dawo da ingot.

Na biyu, ana amfani da shi azaman inoculant da spheroidizing wakili a masana'antar simintin ƙarfe.Simintin ƙarfe shine muhimmin kayan ƙarfe a masana'antar zamani.Yana da arha fiye da ƙarfe kuma yana da sauƙin narkewa da narkewa.Yana da kyawawan kaddarorin simintin gyare-gyare kuma mafi kyawun ƙarfin girgiza fiye da ƙarfe.Musamman baƙin ƙarfe na nodular simintin gyare-gyare, kayan aikin injiniyansa sun kai ko kusanci kayan aikin ƙarfe.Ƙara wani adadin ferrosilicon don jefa baƙin ƙarfe zai iya hana samuwar carbide a cikin baƙin ƙarfe da haɓaka hazo da spheroidization na graphite.Saboda haka, ferrosilicon wani muhimmin inoculant ne (don taimakawa hazo graphite) da kuma spheroidizing wakili a cikin samar da nodular simintin ƙarfe.

Bugu da ƙari, ana amfani da shi azaman ragewa wakili a cikin samar da ferroalloy.Ba wai kawai alaƙar sinadarai tsakanin silicon da oxygen yana da girma ba, har ma da abubuwan da ke cikin carbon na babban silicon ferrosilicon yana da ƙasa sosai.Saboda haka, babban silicon ferrosilicon (ko siliceous gami) wani na kowa ragewa wakili a cikin samar da low-carbon ferroalloy a cikin ferroalloy masana'antu.
