Mabda'a wax soo saarka casriga ah ee daboolka godka birta ee birta, waxaan ku dhejin karnaa birta birta ah iyada oo loo marayo birta la tuuray iyo birta la been abuurtay, taas oo si ballaaran loo isticmaalo warshadaha wax soo saarka farsamada maanta.Dhab ahaantii, mabda'a birta ductile waa in la helo graphite leh qaab isku mid ah sida kubbadda iyada oo loo marayo habka spheroidization, taas oo si wax ku ool ah u wanaajisa waxqabadka birta birta ah, gaar ahaan caagadeeda iyo adkaanta, taasoo keentay tayada sare ee birta kaarboon.Si kastaba ha ahaatee, si loo dhimo kharashaadka, daboolka godka birta ductile waxaa guud ahaan la been abuuraa iyadoo la isticmaalayo kabka iyo birta been abuurka ah.
Birta birta ah waa wax jajaban.Marka hore, birta la shubay macnaheedu waa kaarboon ka weyn 2.1% (oo leh kaarboon ka kooban 3.50-3.90% iyo qaab-dhismeedka birta ah ee ferrite+pearlite).Haddii waxa ku jira kaarboonku sarreeyo, engegnaantiisu hubaal way sarraysaa.Marka labaad, spheroidizing birta ductile waxay ka dhigan tahay in cabbirka qaybaha birta ay hoos u dhacaan, taas oo sidoo kale hagaajin doonta xoogga iyo adkaanta walxaha.Marka guud ahaan marka la hadlo, engegnaanta birta ductile waa mid aad u sareysa (waxaa hubaal ah inay ka sarreyso tan birta caadiga ah).
Marka hore, baabuurta culculus ayaa inta badan loo adeegsadaa taraafikada waddooyinka, sidaas darteed daboolka birta birta ah ayaa guud ahaan la doortaa, kuwaas oo qaadi kara ilaa 40 tan;Qaar ka mid ah daboolka godad godad ah oo isku dhafan ayaa sidoo kale gaari kara awoodda qaadida ilaa 25 tan, taas oo ka raqiisan birta ductile.Si kastaba ha ahaatee, daboolka godka xuubka birta ah ayaa ah mid ammaan ah.
Marka labaad, marka la barbar dhigo daboolada godad isku dhafan, daboolada godka xuubka birta ah waxay u badan tahay in ay bartilmaameedsadaan tuugada.Daboolka godka birta ee birta ma aha oo kaliya inay leeyihiin awood wanaagsan oo qaadis ah, laakiin sidoo kale waxay diiradda saaraan naqshadeynta faahfaahin kasta oo daboolka birta birta ah, gaar ahaan marka la eego waxqabadka ka hortagga xatooyada, oo si dhab ah u qasba tuugada ilaa heer aysan helin hab ay ku bilaabaan. qofna ma xadi karo.Dadka qaarkiis ayaa laga yaabaa inay ka walwalaan in daboolka godka birta ee birta ah ay samayn karaan qaylo dheer marka la sii wado, taas oo ah waxoogaa aan loo baahnayn sababtoo ah horay ayaan u tixgelinnay arrintan naqshadeena.Dabool kasta oo godad ah ayaa lagu sameeyay daawaynta dhimista buuqa ka hor inta aan laga tagin warshadda, taas oo gabi ahaanba go’doomisay dhibaatada wasakhowga sawaxanka ee daboolka godad birta ah.
Ugu dambeyntii, awoodda rarka ee daboollada godad isku dhafan ayaa aad uga yar kuwa daboolka godka xuubka birta.Meelaha sida suunka cagaaran iyo waddooyinka aan u baahnayn cadaadis weyn, kharashka isticmaalka daboolka godad isku dhafan ayaa aad uga hooseeya tan isticmaalka daboolka godka birta.
