Ihe ntụgharị nchara na-eme calcium silicon Si40 Fe40 Ca10

Mgbe silicon-calcium alloy na-deoxidized, na-abụghị metal inclusions na ibu irighiri na mfe sere n'elu, a na-agbanwekwa udi na Njirimara nke na-abụghị metal inclusions.Ya mere, a na-eji silicon-calcium alloy na-emepụta ígwè dị ọcha, ígwè dị elu nke nwere obere ikuku oxygen na sọlfọ, na ígwè ọrụ pụrụ iche nke nwere oke ikuku oxygen na sọlfọ dị ala.Mgbakwunye nke silicon-calcium alloy nwere ike iwepụ nodulation nke ígwè na aluminum dị ka deoxidizer ikpeazụ na ladle nozzle, na clogging nke nozzle nke tundish nke na-aga n'ihu nkedo |ime ígwè.Na teknụzụ nchacha ígwè n'èzí ọkụ ahụ, a na-eji silicon-calcium ntụ ntụ ma ọ bụ eriri isi mee ihe maka deoxidation na desulfurization iji belata ọdịnaya nke oxygen na sọlfọ na ígwè na ọkwa dị ala;ọ nwekwara ike ijikwa ụdị sulfide na nchara ma melite ọnụego ojiji nke calcium.Na mmepụta nke ígwè nkedo, na mgbakwunye na deoxidation na ịdị ọcha, silicon-calcium alloy na-arụkwa ọrụ inoculating, nke na-enyere aka ịmepụta ihe dị mma ma ọ bụ graphite;na-eme ka graphite na nkedo isi awọ na-ekesa nke ọma, na-ebelata ọchịchọ nke ịcha ọcha;ma nwee ike ịbawanye silicon na desulfurize , Meziwanye nkedo ígwè.
