I-Ferrosiliconiyingxubevange yensimbi ne-silicon.I-Ferrosilicon i-coke, i-steel chips, i-quartz (noma i-silica) njengezinto zokusetshenziswa, ezincibilikiswa ngesithando somlilo sikagesi esenziwe nge-iron silicon alloy.Ngenxa yokuthi i-silicon ne-oksijini kulula ukuhlanganisa ku-silicon dioxide, ngakho-ke i-silicon ye-ferric ivame ukusetshenziswa njenge-deoxidizer ekwenzeni insimbi.Ngesikhathi esifanayo, ngoba i-SiO2 ikhiqiza ukushisa okuningi, i-deoxidizing ngesikhathi esifanayo, kuyasiza futhi ukuthuthukisa izinga lokushisa lensimbi encibilikisiwe. i-alloy structural steel, i-spring steel, i-bearing steel, insimbi engavimbeli ukushisa nensimbi ka-silicon kagesi, i-ferrosilicon emkhiqizweni we-ferroalloy kanye nomkhakha wamakhemikhali, evame ukusetshenziswa njenge-ejenti yokunciphisa.

(1) Isetshenziswa njenge-deoxidizer kanye ne-alloying embonini yokwenza insimbi. Ukuze kutholwe ukwakheka kwamakhemikhali okufanelekile ensimbi futhi kuqinisekiswe ikhwalithi yensimbi, esigabeni sokugcina sokwenziwa kwensimbi kufanele kukhishwe i-deoxidized, i-silicon nomoya-mpilo phakathi kokuhambisana kwamakhemikhali enkulu, ngakho-ke i-ferrosilicate iyi-agent e-deoxidizing eqinile esetshenziselwa ukuna nokukhipha i-deoxidization. Ukwengeza inani elithile le-silicon ensimbi kungathuthukisa kakhulu amandla, ukuqina nokunwebeka kwensimbi, ngakho-ke ekuncibilikeni kwensimbi yesakhiwo (equkethe i-silicon 0.40- 1.75%), insimbi yamathuluzi (equkethe i-Sio.30-1.8%), i-spring steel (equkethe i-Sio.40-2.8%) ne-transformer silicon steel (equkethe i-silicon 2.81-4.8%), i-ferrosilicon nayo isetshenziswa njenge-alloying ejenti. ngesikhathi esifanayo, ukuthuthukisa ukufakwa kanye nokunciphisa okuqukethwe kwezakhi zegesi ensimbi encibilikisiwe kuwubuchwepheshe obusha obuphumelelayo bokuthuthukisa ikhwalithi yensimbi, ukunciphisa izindleko nokulondoloza insimbi.Kufaneleka ngokukhethekile i-deoxidization ye-moltinsimbi ekubunjweni okuqhubekayo.Kuye kwafakazelwa ngomkhuba ukuthi i-ferosilicate ayigcini nje ngokuhlangabezana nezidingo ze-deoxidization yokwenza insimbi, kodwa futhi inokusebenza kwe-desulfurization futhi inezinzuzo zesilinganiso esikhulu kanye nokungena okuqinile.

Ngaphezu kwalokho, embonini yokwenza insimbi, i-ferosilicon powder ivame ukusetshenziswa njenge-ejenti yokushisa i-ingot cap ukuze kuthuthukiswe ikhwalithi nokubuyiselwa kwe-ingot, isebenzisa isici sokuthi i-ferosilicon powder ingakhipha ukushisa okukhulu kakhulu. izinga lokushisa.

(2) Isetshenziswa njenge-inoculant kanye ne-spheroidizer embonini ye-cast iron.I-cast iron iyinto ebalulekile yensimbi embonini yesimanje.Ishibhile kunensimbi, kulula ukuncibilika futhi incibilike, futhi inekhono lokulingisa elihle kakhulu nekhono elingcono kakhulu le-aseismic kunensimbi.I-Ductile iron, ikakhulukazi, inezici zomshini ezilingana noma ezisondelene nalezo zensimbi.Yengeza inani elithile le-ferrosilicon insimbi ephonsiwe ingavimbela ukwakheka kwe-carbide ensimbi, ikhuthaze imvula kanye ne-spheroidization ye-graphite, ngakho-ke ekukhiqizeni i-nodular cast iron, i-ferrosilicon iyi-inoculant ebalulekile (ukusiza imvula ye-graphite) ne-spheroidizer.

(3) esetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni i-ferroalloy.Akukhona nje kuphela ukuthi ukuhlobana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kuhle kakhulu, kodwa okuqukethwe kwekhabhoni ku-silicon ferrosilicon ephezulu kuphansi kakhulu.Ngakho-ke, i-silicon ferrosilicon ephezulu (noma i-siliceous alloy) iwukunciphisa okuvame ukusetshenziswa. i-ejenti ekukhiqizeni i-carbon ferroalloy ephansi embonini ye-ferroalloy.

4 iqhaza ekukhiqizeni i-magnesium.

(5) ngezinye izinjongo.I-ferrosilicon powder egayiwe noma i-atomized ingasetshenziswa njengesigaba esimisiwe embonini yokucubungula izimbiwa.Ingasetshenziswa njenge-coating ye-electrode embonini yokukhiqiza ama-electrode.I-silicon ferrosilicon ephezulu embonini yamakhemikhali ingasetshenziselwa ukukhiqiza. abicah kanye neminye imikhiqizo.

Phakathi kwalezi zinhlelo zokusebenza, izimboni ze-steelmaking, foundry kanye ne-ferroalloy zingabasebenzisi abakhulu be-ferrosilicate.Ndawonye, ​​zisebenzisa ngaphezu kuka-90% we-ferrosilicon.Emabangeni ahlukene ahlukene e-ferrosilicon, esetshenziswa kakhulu yi-75% ferrosilicon.Embonini yokwenza insimbi. , cishe i-3-5kg75% ye-ferrosilicon isetshenziswa ku-1t ngayinye yensimbi ekhiqizwayo.
