(1) Isetshenziswa njenge-deoxidizer kanye ne-alloying 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 kukhulu kakhulu, ngakho i-ferrosilicon iyi-deoxidizer ebaluleke kakhulu embonini yokwenza insimbi. Emkhiqizweni wokwenza insimbi, ngaphandle kwezinye izinsimbi ezibilayo, cishe zonke izinhlobo zensimbi zisebenzisa i-ferrosilicon njenge-deoxidizer eqinile yokukhipha ama-oxidation kwemvula kanye ne-diffusion deoxidation. Ukwengeza inani elithile le-silicon ensimbi kungathuthukisa kakhulu amandla, ukuqina nokunwebeka kwensimbi. Ngakho-ke, isetshenziswa kakhulu ekuncibilikiseni insimbi yesakhiwo (equkethe i-siO. 40% ~ 1.75%) kanye nensimbi yamathuluzi (equkethe i-siO. 30%). ~ 1.8%), insimbi yasentwasahlobo (equkethe i-Si O. 40% ~ 2.8%) kanye nezinye izinhlobo zensimbi, inani elithile le-ferrosilicon kumele lengezwe njenge-alloying agent. I-silicon nayo inezici zokumelana okukhulu okuqondile, ukungahambi kahle kwe-thermal kanye ne-conductivity enamandla kazibuthe. Insimbi iqukethe inani elithile le-silicon, elingathuthukisa amandla kazibuthe ensimbi, inciphise ukulahleka kwe-hysteresis, futhi inciphise ukulahlekelwa kwamanje kwe-eddy. Ngakho-ke, i-ferrosilicon iphinde isetshenziswe njenge-alloying ejenti lapho kuncibilika i-silicon steel, njengensimbi ephansi ye-silicon yamamothoni (equkethe i-Si O. 80% kuya ku-2.80%) kanye nensimbi ye-silicon yama-transformers (equkethe i-Si 2.81% kuya ku-4.8%). sebenzisa.

Ukwengeza, embonini yokwenza insimbi, i-ferrosilicon powder ingakhulula inani elikhulu lokushisa lapho ishiswa emazingeni okushisa aphezulu futhi ivame ukusetshenziswa njenge-ejenti yokushisa ye-ingot caps yensimbi ukuze kuthuthukiswe izinga kanye nezinga lokubuyisela lezinsimbi zensimbi.


(2) Isetshenziswa njenge-ejenti yokugomela kanye ne-spheroidizing embonini ye-cast iron. I-cast iron iyinto ebalulekile yensimbi embonini yesimanje. Ishibhile kunensimbi, kulula ukuncibilika futhi incibilike, inezinto ezinhle kakhulu zokuphonsa kanye nokumelana nokuzamazama komhlaba okungcono kakhulu kunensimbi. Ikakhulukazi i-ductile iron, izakhiwo zayo zemishini zifinyelela noma ziseduze nalezo zensimbi. ukusebenza. Ukwengeza inani elithile le-ferrosilicon ukuphonsa insimbi kungavimbela ukwakheka kwama-carbides ensimbi futhi kukhuthaze ukuna kanye ne-spheroidization ye-graphite. Ngakho-ke, ekukhiqizeni i-ductile iron, i-ferrosilicon iyi-inoculant ebalulekile (esiza ukwehlisa i-graphite) kanye ne-spheroidizing agent. .


(3) Isetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni i-ferroalloy. Akukhona nje kuphela ukuthi ukuhlobana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kuphezulu kakhulu, kodwa okuqukethwe kwekhabhoni ye-silicon ferrosilicon ephezulu kuphansi kakhulu. Ngakho-ke, i-ferrosilicon ephezulu ye-silicon (noma ingxubevange ye-silicon) iyi-ejenti yokunciphisa evame ukusetshenziswa embonini ye-ferroalloy lapho ikhiqiza ama-ferroalloy anekhabhoni ephansi.
