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 ihe ikpeazụ deoxidizer na ladle nozzle, na clogging nke nozzle nke tundish nke na-aga n'ihu nkedo | ime ígwè. Na teknụzụ nchacha nchara 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 ogo 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.
