Yiziphi izinhlelo zokusebenza ze-ferrosilicon?

I-Ferrosilicon, i-alloy ye-silicon nensimbi, itholakala ku-45%, 65%, 75% kanye nama-90% amamaki e-silicon.Ukusetshenziswa kwayo kubanzi kakhulu, khona-ke umkhiqizi we-ferrosilicon i-Anhui Fitech Materials Co., Ltd izohlaziya ukusetshenziswa kwayo okuqondile kumaphuzu amathathu alandelayo.

Okokuqala, isetshenziswa njenge-deoxidizer kanye ne-alloying embonini yokwenza insimbi.Ukuze uthole insimbi ngokwakhiwa kwamakhemikhali afanelekayo futhi uqinisekise ikhwalithi yensimbi, i-deoxidation kufanele yenziwe ekupheleni kwe-steelmaking.Ukuhlobana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kukhulu kakhulu.Ngakho-ke, i-ferrosilicon iyi-deoxidizer eqinile yokwenza insimbi, esetshenziselwa imvula kanye ne-diffusion deoxidation.Ukwengeza inani elithile le-silicon ensimbi kungathuthukisa kakhulu amandla, ukuqina nokunwebeka kwensimbi.
Ngakho-ke, i-ferrosilicon iphinde isetshenziswe njenge-alloying agent lapho incibilikisa insimbi yesakhiwo (equkethe i-silicon 0.40-1.75%), insimbi yamathuluzi (equkethe i-silicon 0.30-1.8%), insimbi yasentwasahlobo (equkethe i-silicon 0.40-2.8%) nensimbi ye-silicon ye-transformer ( equkethe i-silicon 2.81-4.8%).

Ngaphezu kwalokho, embonini yokwenza insimbi, i-ferrosilicon powder ingakhulula inani elikhulu lokushisa ngaphansi kokushisa okuphezulu.Ivamise ukusetshenziswa njenge-ejenti yokushisisa ye-ingot cap ukuze kuthuthukiswe ikhwalithi nokutholwa kwe-ingot.

Okwesibili, isetshenziswa njenge-ejenti ye-inoculant kanye ne-spheroidizing embonini ye-cast iron.I-cast iron iyinto ebalulekile yensimbi embonini yesimanje.Kushibhile kunensimbi futhi kulula ukuncibilika nokuncibilika.Inezici ezinhle kakhulu zokuphonsa nekhono lokushaqeka elingcono kakhulu kunensimbi.Ikakhulukazi insimbi eyi-nodular cast iron, izakhiwo zayo zemishini zifinyelela noma zisondele ezindaweni zensimbi.Ukwengeza inani elithile le-ferrosilicon ukuphonsa insimbi kungavimbela ukwakheka kwe-carbide ensimbi futhi kukhuthaze imvula kanye ne-spheroidization ye-graphite.Ngakho-ke, i-ferrosilicon iyi-inoculant ebalulekile (ukusiza ukukhipha i-graphite) kanye ne-spheroidizing agent ekukhiqizeni i-nodular cast iron.

Ngaphezu kwalokho, isetshenziswa njenge-ejenti yokunciphisa ekukhiqizeni i-ferroalloy.Akukhona nje kuphela ukuhlangana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kuhle, kodwa futhi okuqukethwe kwekhabhoni ye-silicon ferrosilicon ephezulu kuphansi kakhulu.Ngakho-ke, i-silicon ferrosilicon ephezulu (noma ingxubevange ye-siliceous) iyi-ejenti yokunciphisa evamile ekukhiqizweni kwe-ferroalloy enekhabhoni ephansi embonini ye-ferroalloy.
