Intengo Ekhethekile Yekhava Yepulasitiki Eyindilinga Yeshubhu

Njengomphumela wokukhethekile kwethu kanye nokuqaphela isevisi, inkampani yethu izuze idumela elihle phakathi kwamakhasimende emhlabeni wonke ngenani elikhethekile le-Round Shape Plastic Cover for Tube, Sikulungele ukubambisana nebhizinisi labangane abahle abavela endlini yakho naphesheya kwezilwandle. futhi nenze isikhathi eside esihle kakhulu ngokuhlanganyela.
Ngenxa yobungcweti bethu kanye nokuqaphela isevisi, inkampani yethu izuze idumela elihle phakathi kwamakhasimende emhlabeni wonkeIkhava Yepulasitiki YaseChina Nesembozo Sepulasitiki, Imisebenzi yethu yebhizinisi nezinqubo zakhelwe ukwenza isiqiniseko sokuthi amakhasimende ethu afinyelela uhla olubanzi kakhulu lwemikhiqizo enemigqa yesikhathi emfishane.Le mpumelelo yenziwe ithimba lethu elinamakhono aphezulu nelinolwazi olunzulu.Sibheka abantu abafuna ukukhula nathi emhlabeni wonke futhi bahluke esixukwini.Manje sinabantu abamukela ikusasa, abanombono, abathanda ukwelula izingqondo zabo futhi badlulele ngale kwalokho ababecabanga ukuthi kungafezwa.

Isingeniso esifushane:

I-Ductile iron, eyaziwa nangokuthi i-ductile cast iron, i-nodular cast iron, i-spherical graphite iron, i-spherical graphite cast iron kanye ne-SG iron, iwuhlobo lwensimbi exutshwe ne-graphite eyatholwa ngo-1943 nguKeith Millis.Nakuba izinhlobo eziningi zensimbi ekhonjiwe zibuthakathaka ekuqineni nasekuqineni, i-iron ductile inomthelela omkhulu kakhulu kanye nokumelana nokukhathala, ngenxa yokufakwa kwayo kwama-nodular graphite.I-Ductile iron ayiyona into eyodwa kodwa iyingxenye yeqoqo lezinto ezingakhiqizwa ngezinhlobonhlobo zezakhiwo ngokulawulwa kwe-microstructure yazo.Isici esivamile esichaza leli qembu lezinto zokwakha ukuma kwegraphite.Kuma-ayina ama-ductile, i-graphite isesimweni samaqhuqhuva esikhundleni sama-flakes njengasensimbi empunga.Nakuba ama-graphite flakes abukhali adala amaphuzu okugxilisa ingqondo ngaphakathi kwe-metal matrix, ama-nodule ayindilinga avimbela ukwakhiwa kwemifantu, ngaleyo ndlela anikeze i-ductility ethuthukisiwe enikeza ingxubevange igama layo.

I-Austempered ductile iron (ADI; okungukuthi, i-austenite tempered[7]) yatholwa ngeminyaka yawo-1950s kodwa yathengiswa futhi yazuza impumelelo eminyakeni ethile kamuva.Ku-ADI, isakhiwo se-metallurgical sisetshenziswa ngenqubo eyinkimbinkimbi yokwelapha ukushisa.

Ukwakheka

Ingxenye enkulu (%) ye-ferritic ductile iron castings[8]

Ezinye izinhlobo ze-iron ductile ngokuvamile zinenani elincane lesulfure.

Ikhabhoni, 3.2–3.60%

I-silicon, 2.2–2.8%

I-Manganese, 0.1–0.2%

I-Magnesium, 0.03–0.04%

I-Phosphorus, 0.005–0.04%

Isibabule, 0.005–0.02%

Ithusi, <0.40%

Insimbi, ibhalansi

Ama-elementi afana nekhopha noma ithini angase angezwe ukuze kwandiswe amandla futhi anikeze amandla ngesikhathi esifanayo kwehliswe i-ductility.Ukumelana nokugqwala okuthuthukisiwe kungafinyelelwa ngokufaka i-15-30% yensimbi ku-alloy ngamanani ahlukahlukene e-nickel, ithusi, noma i-chromium.

I-silicon njengengxenye yokwakheka kwe-graphite ingathathelwa indawo yi-aluminium ukuze inikeze ukuvikeleka okungcono kwe-oxidation.[9]

I-HONGDA Ductile iron castings:

Ekuqaleni kuka-2021, i-HONGDA yakha imboni entsha ukwethula izinto zokusebenza kanye nomugqa wokukhiqiza we-Ductile Iron Casting.
1. Okubalulekile: I-QT450#-10 kanye nezinga le-Spheroidization lingaphezu kweleveli III ukuze uthole ikhwalithi enhle yokulingisa ukusekela isicelo sakho.
2. Ulayini wokukhiqiza ozenzakalelayo ukuze ufinyelele ukusebenza kahle okuphezulu kanye nokukhiqizwa kwamandla amakhulu, ama-550T/Inyanga, ukubuyisela isidingo sakho esiphuthumayo.
3.Izicelo: i-ductile iron castings ye-roller collar, i-bracket engenzi lutho kanye nokunye okufana nezingxenye zokulingisa ngaphakathi kuka-70KGS. Njengomphumela wokukhethekile kwethu nokuqaphela isevisi, inkampani yethu izuze idumela elihle phakathi kwamakhasimende emhlabeni jikelele ngenani elikhethekile le-Round Shape. Ikhava Yepulasitiki Yeshubhu, Silungele ukubambisana nebhizinisi labangane abahle abavela endlini yakho naphesheya kwezilwandle futhi senze isikhathi eside esihle kakhulu ngokuhlanganyela.
