Chiyambi Chachidule:

Chitsulo chachitsulo, chomwe chimadziwikanso kuti ductile cast iron, nodular cast iron, spherical graphite iron, spherical graphite cast iron ndi SG iron, ndi mtundu wa chitsulo cholemera kwambiri cha graphite chomwe chinapezeka mu 1943 ndi Keith Millis.Ngakhale kuti mitundu yambiri yachitsulo imakhala yofooka komanso yofooka, chitsulo cha ductile chimakhala ndi mphamvu zambiri komanso kukana kutopa, chifukwa cha ma nodular graphite inclusions.Chitsulo chachitsulo sichinthu chimodzi koma ndi gawo la gulu la zipangizo zomwe zingathe kupangidwa ndi katundu wambiri pogwiritsa ntchito kayendetsedwe ka microstructure.Chikhalidwe chodziwika bwino cha gulu ili la zipangizo ndi mawonekedwe a graphite.Muzitsulo za ductile, graphite ili mu mawonekedwe a tinthu tinatake tozungulira m'malo mwa ma flakes ngati chitsulo chotuwira.Pomwe ma flakes akuthwa a graphite amapanga malo opanikizika mkati mwazitsulo zachitsulo, tinthu tating'onoting'ono tozungulira timalepheretsa kupanga ming'alu, motero kumapangitsa kuti aloyiyo adziwike bwino.

Austempered ductile iron (ADI; mwachitsanzo, austenite tempered[7]) idapezeka mu 1950s koma idagulitsidwa ndikupindula zaka zingapo pambuyo pake.Mu ADI, kapangidwe kazitsulo kachitsulo kamene kamagwiritsidwa ntchito pochiza kutentha kwambiri.

Kupanga

Kagawo kakang'ono (%) kwa ferritic ductile iron castings[8]

Mitundu ina yachitsulo ya ductile nthawi zambiri imakhala ndi sulfure pang'ono.

Mpweya, 3.2–3.60%

Silicon, 2.2-2.8%

Manganese, 0.1–0.2%

Magnesium, 0.03-0.04%

Phosphorasi, 0.005-0.04%

Sulfure, 0.005-0.02%

Mkuwa, <0.40%

Iron, balance

Zinthu monga mkuwa kapena tini zitha kuwonjezeredwa kuti ziwonjezeke komanso kutulutsa mphamvu panthawi imodzi zimachepetsa ductility.Kuchuluka kwa dzimbiri kungathe kutheka pochotsa 15-30% ya chitsulo mu aloyi ndi mitundu yosiyanasiyana ya faifi tambala, mkuwa, kapena chromium.

Silikoni ngati chinthu chopangira ma graphite amatha kusinthidwa pang'ono ndi aluminiyumu kuti apereke chitetezo chabwino kwambiri cha okosijeni.[9]

HONGDA Ductile iron castings:

Kumayambiriro kwa 2021, HONGDA anamanga fakitale yatsopano kuti adziwitse zida ndi mzere wopanga Ductile Iron kuponyera.
1. Zofunika: QT450#-10 ndi Spheroidization mlingo wadutsa mlingo III kuti mupeze khalidwe labwino la castings kuthandizira pempho lanu.
2. Makina opanga makina kuti afikire kuchita bwino kwambiri komanso kupanga mphamvu zazikulu, 550T/Mwezi, kuti mubwererenso chosowa chanu mwachangu.
3.Applications: ductile iron castings for roller collar, idler bracket and so like part castings mkati 70KGS.Kuthandizidwa ndi gulu lotukuka kwambiri komanso laukadaulo la IT, titha kupereka chithandizo chaukadaulo pakugulitsa kusanachitike & ntchito yogulitsa pambuyo pamtengo wotsika mtengo China. Cat Bulldozer D7 D7c D7d D7e D7f Single Flange Track Roller Pansi Roller kwa Dozer Undercarriage, Ndi mitundu yambiri, yapamwamba, mtengo wanzeru ndi mapangidwe apamwamba, zothetsera zathu zimagwiritsidwa ntchito kwambiri ndi mafakitale ndi mafakitale ena.
