Ukuhlukaniswa kwe-ferrosilicon

Ukuhlukaniswa kwe-ferrosilicon:

I-Ferrosilicon 75, ngokuvamile, i-ferrosilicon enokuqukethwe kwe-silicon engu-75%, i-carbon low, i-phosphorus ne-sulfur content,

I-Ferrosilicon 72, ngokuvamile iqukethe i-silicon engu-72%, kanti okuqukethwe kwekhabhoni, isulfure ne-phosphorus kuphakathi.

I-Ferrosilicon 65, i-ferrosilicon enokuqukethwe kwe-silicon engu-65%, okuqukethwe okuphezulu kwekhabhoni, isulfure ne-phosphorus uma kuqhathaniswa.

Indima ye-ferrosilicon ekwenzeni insimbi:

Okokuqala: Isetshenziswa njenge-deoxidizer kanye ne-alloying agent embonini yokwenza insimbi.Ukuze uthole insimbi ngokwakhiwa kwamakhemikhali afanelekayo futhi uqinisekise izinga lensimbi, i-deoxidation kufanele yenziwe esigabeni sokugcina sokwenza insimbi.Ukuhlobana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kuphezulu kakhulu, ngakho i-ferrosilicon iyi-deoxidizer eqinile yokwenza insimbi.Imvula kanye nokusabalalisa i-deoxygenation.

Okwesibili: Isetshenziswa njenge-inoculant kanye ne-nodulizer embonini ye-cast iron.I-cast iron iyinto ebalulekile yensimbi embonini yesimanje.Ishibhile kunensimbi, kulula ukuncibilika futhi incibilike, inokusebenza okuhle kakhulu kokulingisa kanye nekhono elingcono kakhulu lokumunca ukushaqeka kunensimbi.Ukwengeza inani elithile le-ferrosilicon ukuze kuphonswe insimbi kungavimbela insimbi ukuthi i-Form carbides, ikhuthaze imvula kanye ne-spheroidization ye-graphite, ngakho-ke ekukhiqizeni i-ductile iron, i-ferrosilicon iyi-inoculant ebalulekile kanye ne-spheroidizer.

Okwesithathu: Isetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni ama-ferroalloys.Akukhona nje kuphela ukuhlangana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kuhle, kodwa futhi okuqukethwe kwekhabhoni ye-silicon ferrosilicon ephezulu kuphansi kakhulu.Ngakho-ke, i-ferrosilicon ephezulu ye-silicon i-ejenti yokunciphisa evame ukusetshenziswa ekukhiqizeni ama-ferroalloys anekhabhoni ephansi embonini ye-ferroalloy.

Okwesine: Ukusetshenziswa okuyinhloko kwezigaxa zemvelo ze-ferrosilicon kufana ne-alloying ejenti ekukhiqizeni insimbi.Angakwazi ukuthuthukisa ubulukhuni, amandla, nokumelana nokugqwala kwensimbi, futhi angakwazi ukuthuthukisa ukushisela nokuqina kwensimbi.

Okwesihlanu: Isetshenziswa kwezinye izindawo.Umhlabathi ocolekile noma owenziwe nge-atomized ferrosilicon powder ungasetshenziswa njengesigaba sokumiswa embonini yokucubungula izimbiwa.
