Nhanganyaya Pfupi:

Ductile iron, inozivikanwawo se ductile cast iron, nodular cast iron, spherical graphite iron, spherical graphite cast iron uye SG iron, imhando ye graphite-rich cast iron yakawanikwa muna 1943 naKeith Millis.Nepo mazhinji emhando dzesimbi yakakandwa isina kusimba mukunetsana uye brittle, ductile iron ine zvakawanda zvinokanganisa uye kuneta kuramba, nekuda kweiyo nodular graphite inclusions.Ductile iron haisi chinhu chimwe chete asi chikamu cheboka rezvigadzirwa zvinogona kugadzirwa nehuwandu hwezvinhu kuburikidza nekutonga kwe microstructure yavo.Izvo zvinowanzotsanangudza hunhu hweboka iri rezvinhu chimiro chegraphite.Mune ductile irons, graphite iri muchimiro chemanodule pane maflakes senge grey iron.Nepo akapinza graphite flakes achigadzira kushushikana kwenzvimbo mukati mesimbi matrix, akatenderedzwa nodule anotadzisa kugadzirwa kwepakatsemuka, nekudaro ichipa iyo yakakwidziridzwa ductility iyo inopa alloy zita rayo.

Austempered ductile iron (ADI; kureva, austenite tempered [7]) yakawanikwa muma1950s asi yakatengeswa uye yakabudirira makore akati gare gare.MuADI, iyo metallurgical chimiro inogadziriswa kuburikidza neyakaomesesa kupisa kupisa maitiro.

Composition

Chikamu chemisa (%) cheferritic ductile iron castings[8]

Zvimwe zvinyorwa zve ductile iron zvinowanzova nesarufa shoma zvakare.

Kabhoni, 3.2–3.60%

Silicon, 2.2–2.8%

Manganese, 0.1–0.2%

Magnesium, 0.03–0.04%

Phosphorus, 0.005–0.04%

Sarufa, 0.005–0.02%

Mhangura, <0.40%

Simbi, kuenzanisa

Zvinhu zvakadai semhangura kana tin zvinogona kuwedzerwa kuwedzera kusimba uye goho simba panguva imwe cheteyo kuderedza ductility.Kuvandudzwa kwekupokana kunogona kuwanikwa nekutsiva 15-30% yesimbi mualloy ine huwandu hwakasiyana hwenickel, mhangura, kana chromium.

Silikoni sechinhu chekugadzira girafu inogona kutsiviwa nearuminiyamu zvishoma kuti ipe kuchengetedzwa kweoxidation iri nani.[9]

HONGDA Ductile iron castings:

Mukutanga kwa2021, HONGDA yakavaka fekitori nyowani kusuma michina uye mutsara wekugadzira weDuctile Iron casting.
1. Material: QT450#-10 uye Spheroidization rate iri pamusoro penhanho III kuti uwane yakanaka mhando yekukanda kutsigira chikumbiro chako.
2. Automated production line kuti isvike pakunyatsoshanda uye hukuru hwekugadzira, 550T / Mwedzi, kudzorera chido chako chekukurumidzira.
3.Applications: ductile iron castings ye roller collar, idler bracket uye saka sezvikamu zvekukanda mukati me70KGS.undercarriage parts track drive rim excavator sprocket
