Ukuze kuhlangatshezwane nezidingo zekhasimende, i-Shijiazhuang dong huan metal malleable iron castings co., ltd seyenziwe izifakelo ezintsha zensimbi ezithambile. Ngokwakhiwa kwamakhemikhali wempahla eluhlaza sinokufingqa okuthile.
Amanani C, Si, CE kanye ne-Mg okusakaza kufanele ahlangabezane nezilinganiso eziyinhloko zokusakaza. Usayizi wesigaba sokulingisa unquma izinga lokupholisa lokusakaza, kuyilapho ukwakheka kwamakhemikhali nezinga lokupholisa ngokuhlanganyela kunquma ukwakheka kwe-metallographic yomkhiqizo.
Kokubili i-ferrite cast iron ne-pearlitic cast iron idinga i-Si (ukushintsha Okuqukethwe kwe-Si kusho ukushintsha i-CE) kanye ne-MN.
Ama-castings angahlukaniswa njengenye yama-substrates amabili ngokuya ngokwakheka kwawo kwamakhemikhali, okusho ukuthi kunezithako okungenani ezine ukuze kuzuzwe ukwakheka kwamakhemikhali okufunayo ekukhiqizeni amabanga ahlukene ezingxenye ezinezindonga ezincane neziwugqinsi.
Qaphela:
1. Isisindo sezithako ezihlukahlukene singabalwa ngokuphindaphinda isisindo sensimbi encibilikisiwe ekhiqizwa % % wezithako ezingeziwe.
2. Okuqukethwe kwe-MN kusethwe ngamabomu ezingeni eliphansi, ngoba ku-ferrite nodular iron, ngisho nalapho okuqukethwe kuphansi, kungakhuthaza ukukhiqizwa kwe-pearlite, ku-pearlite, okuqukethwe okuphezulu kwe-MN kulula ukubangela ukuhlukaniswa kwe-MN i-pearlite, ukusebenzisa i-Cu ukwenza ubulukhuni ukuhlangabezana nezidingo ezinqunywe kusengaphambili kuyisinqumo esingcono.
3. I-Silicon carbide ingafakwa ukuze kuncishiswe i-oxidation yensimbi encibilikisiwe futhi ivikele ulayini lwesithando somlilo (inani elingeziwe elingeziwe lingu-0.2%), lingadlala ingxenye yokwanda kwe-C kanye nomphumela we-silicon.
4. Izinga lokumunca ikakhulukazi lika-C no-Si.
