Intshayelelo emfutshane:

Intsimbi yentsimbi, ekwabizwa ngokuba yi-ductile cast iron, nodular cast iron, spherical graphite iron, spherical graphite cast iron and SG iron, luhlobo lwe-graphite-rich cast cast iron eyafunyanwa ngo-1943 nguKeith Millis.Ngelixa uninzi lweentlobo zentsimbi etyhidiweyo zibuthathaka kwi-tension kunye ne-brittle, i-iron ductile inempembelelo enkulu kunye nokumelana nokudinwa, ngenxa yokufakwa kwayo kwe-nodular graphite.I-Ductile iron ayiyona nto enye kodwa inxalenye yeqela lezinto ezinokuveliswa kunye noluhlu olubanzi lweepropati ngokulawulwa kwe-microstructure yazo.Uphawu oluqhelekileyo lweli qela lezinto eziphathekayo yimilo yegraphite.Kwimibhobho ye-iron, igraphite ikwimo yamaqhuqhuva endaweni yeeflakes njengentsimbi engwevu.Ngelixa iiflakthi ezibukhali zegraphite zidala iindawo zoxinzelelo ngaphakathi kwimatrix yesinyithi, amaqhuqhuva angqukuva athintela ukwenzeka kweentanda, ngaloo ndlela ebonelela ngeductility eyandisiweyo enika ingxubevange igama layo.

I-Austempered ductile iron (ADI; okt, iaustenite tempered[7]) yafunyanwa ngo-1950s kodwa yathengiswa kwaye yafumana impumelelo kwiminyaka ethile kamva.Kwi-ADI, isakhiwo se-metallurgical siphathwa ngenkqubo yokushisa ukushisa.

Ukuqamba

Iqhezu lobunzima (%) lokuphoswa kwentsimbi ye-ferritic ductile[8]

Ezinye iziqulatho zentsimbi ye-ductile zihlala zinenani elincinci lesulfure ngokunjalo.

Ikhabhoni, 3.2–3.60%

I-silicon, 2.2-2.8%

IManganese, 0.1–0.2%

I-Magnesium, 0.03-0.04%

I-Phosphorus, 0.005–0.04%

Isulfure, 0.005–0.02%

Ubhedu, <0.40%

Intsimbi, ibhalansi

Izinto ezifana nobhedu okanye i-tin zingongezwa ukunyusa ukunyanzeliswa kunye nokukhupha amandla ngelixa ngaxeshanye kuncitshiswa i-ductility.Ukuphuculwa kwe-corrosion resistance kunokufezekiswa ngokutshintshela i-15-30% yentsimbi kwi-alloy kunye nemilinganiselo eyahlukeneyo ye-nickel, ithusi, okanye i-chromium.

I-Silicon njengento yokwakheka kwegraphite inokutshintshwa ngokuyinxenye yi-aluminiyam ukunika ukhuseleko olungcono lwe-oxidation.[9]

I-HONGDA Ductile castings yentsimbi:

Ekuqaleni kuka-2021, i-HONGDA yakha umzi-mveliso omtsha ukwazisa izixhobo kunye nomgca wemveliso we-Ductile Iron casting.
1. Izinto eziphathekayo: I-QT450 # -10 kunye ne-Spheroidization rate ingaphezulu kwinqanaba le-III ukufumana umgangatho omhle wokuphosa ukuxhasa isicelo sakho.
2. Umgca wokuvelisa ngokuzenzekelayo ukufikelela ekusebenzeni okuphezulu kunye nokuveliswa kwamandla amakhulu, i-550T / Inyanga, ukubuyisela imfuno yakho engxamisekileyo.
I-3.Izicelo: i-ductile iron castings ye-collar ye-roller, i-bracket i-idler kunye nokunye okufana neengxenye ezifakwe ngaphakathi kwe-70KGS. ngokuthe ngcembe.Iimveliso zethu zisebenzisa intsimbi ekhethekileyo kwaye ziveliswa yinkqubo entsha.Yonke inkqubo ihamba ngokuhlolwa okungqongqo kwaye ipropathi yokumelana noxinzelelo kunye nokumelana noxinzelelo inokuqinisekiswa.

I-roller yethu ye-carrier iyasebenza kwi-Komatsu, i-Hitachi, i-Kobelco, i-Daewoo, i-Hyundai, i-Volvo, i-Jcb njl. Sinokunikezela ngenkonzo ye-OEM ngokwemizobo okanye iisampuli zakho.

Iimveliso zithunyelwa kuMzantsi-mpuma we-Asia kunye neYurophu kunye neMelika, zonwabele udumo oluphezulu kwiimarike zasekhaya nezangaphandle.
