Izwe lethu belilokhu linamathisele ukubaluleka okukhulu ekukhiqizeni nasekusetshenzisweni kwezinto ze-metallurgical, futhi liye lazuza intuthuko enhle eminyakeni yamuva.Sonke siyazi ukuthi izimboni zensimbi nezensimbi bezilokhu ziyizimboni ezinkulu emkhakheni wezimboni.Bakhiqiza izimboni ezinemininingwane ehlukahlukene kanye nezakhiwo, ezinomthelela omuhle ekuthuthukisweni kwezimboni.Lokhu futhi kuyisimo esidingekayo ukuze siqhubekise ukukhula komnotho.
I-spheroidal graphite ku-ductile iron yakhiwa ngokwelashwa kwe-spheroidizing iron cast iron, iyenze ibe namandla kakhulu kune-grey cast iron futhi iqine kune-cast cast ironable, kuyilapho igcina uchungechunge lwezinzuzo ze-grey cast iron.Kodwa-ke, "i-ejenti ye-spheroidizing" esetshenziselwa ukuncibilika nokuphonsa insimbi ye-ductile ingakhuphula ukuthambekela kwe-weld ukukhiqiza "amabala amhlophe" nezakhiwo eziqinile, okubangela imifantu endaweni yokushisela kanye nendawo ethinteke ukushisa.
Kungabonakala ukuthi ama-spheroidizing agents adlala indima ebaluleke kakhulu embonini ye-cast iron, futhi okwamanje azikho izinto eziningi ze-metallurgical ezinemiphumela ye-spheroidizing.Lapho imboni ikhiqiza, akufanele nje icabangele umphumela we-spheroidization, kodwa futhi inezidingo zokusetshenziswa kokukhiqiza nokonga amandla nokunciphisa ukusetshenziswa, futhi ingasetshenziswa kuphela ngaphansi kwamazinga okukhiqiza ezwe lami.
Iningi lezinto ezijwayelekile zamapuleti ensimbi embonini zitholakala ngemuva kokwelashwa nge-ejenti ye-spheroidizing.Kungabonakala ukuthi imikhiqizo ye-ejenti ye-spheroidizing izodlala indima enkulu ekuthuthukisweni kwesikhathi esizayo futhi iyimpahla yensimbi ebaluleke kakhulu emkhakheni wezimboni.Singumkhiqizi ochwepheshe wemikhiqizo ye-metallurgical.Imikhiqizo yenkampani iphelele ngezinhlobonhlobo futhi isezingeni elihle.Samukela amakhasimende amasha namadala ukuthi asishayele futhi afake ama-oda.
