Hordhac Kooban:
Birta birta ah, oo sidoo kale loo yaqaano birta kabka ductile, birta nodular kabka ah, birta graphite spherical, graphite cast iron spherical graphite cast iron iyo SG iron, waa nooc ka mid ah birta garaafyada qani ku ah ee laga helay 1943 Keith Millis.Iyadoo inta badan noocyada birta ah ee birta ah ay ku daciifaan xiisadda iyo jilicsanaanta, birta ductile waxay leedahay saameyn aad u badan iyo caabbinta daalka, sababtoo ah ku darida garaafka nodular.Ductile iron ma aha hal shay ee waa qayb ka mid ah koox maaddooyin ah oo lagu soo saari karo waxyaabo badan oo kala duwan iyada oo la xakameynayo qaab-dhismeedkooda yar yar.Tilmaamaha guud ee qeexida kooxdan agabku waa qaabka garaafka.In birta ductile, graphite waa qaab nodules halkii ay ka samaysan yihiin sida birta cawl.Halka jajabyada garaafyada fiiqan ay abuuraan dhibco fiirsashada gudaha shaxanka birta, nodulesyada wareegsan waxay joojiyaan abuuritaanka dildilaaca, sidaas darteed waxay bixiyaan ductility la xoojiyay oo siinaya daawaha magaceeda.
Birta ductile-ka ee Austempered (ADI; ie, austenite tempered[7]) ayaa la helay 1950-meeyadii laakiin waa la baayac-mushtareeyay waxaana lagu guuleystay dhowr sano kadib.Gudaha ADI, qaab dhismeedka biraha waxaa lagu maareeyaa habka daaweynta kulaylka oo casri ah.

Jajabka tirada badan (%) ee shubista birta ductile ee feeritic [8]
Qaybaha kale ee birta ductile waxay inta badan leeyihiin qadar yar oo baaruud ah sidoo kale.
Kaarboon, 3.2-3.60%
Silikoon, 2.2-2.8%
Manganese, 0.1-0.2%
Magnesium, 0.03-0.04%
Fosfooraska, 0.005-0.04%
Baaruud, 0.005-0.02%
Copper, <0.40%

Walxaha ay ka midka yihiin naxaasta ama daasadaha ayaa laga yaabaa in lagu daro si ay u kordhiyaan xajinta oo ay u dhaliyaan xoog iyada oo isla mar ahaantaana la dhimayo ductility.Iska caabbinta daxalka oo la wanaajiyey ayaa lagu gaari karaa iyadoo lagu beddelo 15-30% birta ku jirta daawaha iyadoo lagu beddelo xaddi kala duwan oo nikkel, naxaas ah, ama chromium ah.
Silikoon oo ah curiyaha samaynta garaafyada waxa qayb ahaan lagu bedeli karaa aluminium si loo helo ilaalin ka fiican oo oksaydhka.[9]
HONGDA Ductile bir tuurista:
Horraantii 2021, HONGDA waxay dhistay warshad cusub si ay u soo bandhigto qalabka iyo khadka wax soo saarka ee Ductile Iron tuurista.
1. Qalabka: QT450#-10 iyo heerka Spheroidization ayaa ka sarreeya heerka III si aad u hesho tayada wanaagsan ee kabka si ay u taageeraan codsigaaga.
2. Khadka wax-soo-saarka otomaatiga ah si loo gaaro wax-ku-oolnimo sare iyo wax-soo-saarka baaxadda leh, 550T/Bishii, si loo taageero baahidaada degdegga ah.
3.Applications: shubka birta ductile ee rullaluistemadka, bracket idler iyo si la mid ah qaybo ka mid ah shubista gudahood 70KGS.We have a full range of sprockets and sprocket segments in stock and available for Despatch degdeg ah si ay ugu haboon excavators, excavators mini, dozers, burburin, screeners. iyo mashiino kale oo dabagal lagu sameeyo.
Sprockets-yadayada MZ waxay ka samaysan yihiin bir tayo leh oo leh muuqaalada iligga dibadda ee qotodheer ee qotodheerta oo lagu adkeeyey cimriga ugu badan iyo qaybaha waa la been abuurtay oo si fiican loo adkeeyey nolosha maqaamnimada dheer.
US wac oo la hadal khabiirada sprocket-ka wax ku saabsan dalbashada.
