Eileamaidean a-thìde a chaidh a chleachdadh gu cumanta ann an iarann caladh liath

Faodaidh na h-eileamaidean a-riamh a chuir ris ann an iarann leaghaidh liath a roinn gu garbh ann an ceithir roinnean, eileamaidean grafizition, bead a 'seasmadh eileamaidean agus eileamaidean ath-leasaichte .
Anns a 'phròiseas a thilgeas còmhdach iarainn, carbon, silicon, alùmanum, tha dleastanasan dùbailte le copar {{2} {{2 {0 0 {0. A' brosnachadh copadh rè an eadar-ghluasad aig an Tèirestal; A 'cur casg air co-ghluasaid rè eadar-ghluasad an Cúctrystal, a chuidicheas le bhith a' cruthachadh grìogagan nas ciùine, mar sin faodaidh e cuideachd eileamaid seasmhach .
Tha buaidh an Titanium cuideachd iom-fhillte . san fharsaingeachd, tha Titanium na eileamaid làidir carbach, ach nuair a tha an susbaint aige glè bheag (e {1} .<0.08%), its fine compounds can be used as the core of graphite, has the role of promoting graphitization.
Faodaidh staoin, an Neach-cur ris, Manganese, Mooilbudenum, a 'chromium a chuir a-steach do shild-grafaichean agus fàs grafaigeach, a tha a' cur bacadh air salchd<0.8%, the effect of molybdenum is mild, which is to make the pearlite refinement, the content is the carburization stable element. It is generally believed that the role of manganese is to increase the amount of cast iron beads and improve the strength of cast iron. In fact, manganese is also multifaceted, when the content is high, it will make the graphite thick, thus reducing the strength of cast iron.
