Yini izingxenye zensimbi ze-Sintered:
Izingxenye zensimbi ezisikiwe zenziwa kusetshenziswa inqubo ye-powder metallurgy ebizwa ngokuthi i-sintering. Ngale ndlela, impushana yensimbi icindezelwa ibe yisimo esinembile, bese ukushisa kusetshenziselwa ukunamathisela izinhlayiya zensimbi ngaphakathi kwento edaliwe, okuyenza ikwazi ukugcina isimo sayo esisha. I-Sintering ingasetshenziselwa ukukhiqiza izinhlobo eziningi zezingxenye zensimbi futhi ihambisana nezinsimbi eziningi ezahlukene kanye nama-alloys.
I-JIEHUANG I-Sintered Metals ingochwepheshe bezinqubo zokucwilisa ezishintshayo ezishintsha izinsimbi eziyimpushana zibe yimikhiqizo yensimbi eqinile, ethembekile. Funda kabanzi mayelana nenqubo ye-metal sintering nokuthi ingasiza kanjani isicelo sakho ngokufunda kuqhubeke.
Ithini inqubo ye-sintering:
Inqubo ye-Sintering iwukulungisa i-iron ore powder, i-flux, i-fuel kanye ne-substitutes ngokuvumelana nezidingo zokuncibilikisa kwesithando somlilo, ngokusho kwengxenye ethile yokuxubha, ukuxuba, nokwengeza ukugcotshwa kwamanzi. I-regranulation, ukuthungela kokusabalalisa, ngosizo lwe-fan, ukuze ngaphansi kwesenzo sokushisa okuthile okuphezulu, ingaphezulu le-iron ore powder lithambisa futhi lincibilike, likhiqize isigaba esithile se-liquid, nezinye izinhlayiya zokugcina ezincibilikayo, emva kokupholisa, isigaba se-liquid sizonamathela izinhlayiya ze-mineral powder zibe amabhulokhi le nqubo iyinqubo ye-sintering.
Inqubo eyisisekelo ye-sintering
ukucindezela impushana → ukushaja (ukulungiselela ngaphambi kokulayisha nokucwiliswa) → ukucwilisa (ukushisa kuqala, ukulondoloza ukushisa nokupholisa) → ukuphuma → umzimba osikiwe
Yiziphi izinzuzo Sintered metal izingxenye
●Ngokusebenzisa i-sintering, i-sinter yekhwalithi ephezulu enokwakheka kwamakhemikhali okuzinzile, usayizi wezinhlayiyana ezifanayo, ukunciphisa okuhle nokusebenza okuphezulu kwe-metallurgical kunganikezwa isithando somlilo esiqhumayo, okudala izimo ezinhle zekhwalithi ephezulu, isivuno esiphezulu, ukusetshenziswa okuphansi nokuphila isikhathi eside.
●Ingakwazi ukususa ukungcola okuyingozi njengesibabule, i-zinc, njll.;
● Udoti wezimboni, njengothuli lwesithando somlilo, insimbi egoqiwe, i-sulfuric acid slag, i-steel slag, njll.;
● Izinsimbi ezingezona ayoni nezinsimbi zomhlaba ezingavamile zingatholwa.
Ibanga lokushisa le-Sintering lensimbi ye-Sintered
| Izinga lokushisa le-Sintering | Izibonelo zemikhiqizo e-sintered |
| 1050 | Ikhabhoni ephezulu (ngaphezulu kuka-2.5% wegraphite), ukuminyana okuphansi ( |
| 1080 | Ukuthwala amafutha aphezulu, umhlahlandlela we-valve, okuqukethwe kwe-graphite kwezingxenye ze-anti-friction ezingu-1.5-2.5%. |
| 1120 | Izingxenye zesakhiwo se-iron (Fe-C, Fe-Cu-C), lapho okuqukethwe kwe-graphite |
| > 1150 | Izingxenye zesakhiwo ezinamandla amaphakathi futhi aphezulu (okuqukethwe kwegraphite |
Yini Common sinteredizinto zensimbi:
Ingxubevange eqinile: eyakhiwe nge-tungsten, i-cobalt, i-carbon nezinye izinsimbi, ezinobulukhuni obuphezulu, ukumelana nokugqoka okuqinile, ukumelana nokugqwala nezinye izakhiwo, ezisetshenziswa kabanzi ekwenzeni imishini, izimayini neminye imikhakha.
Ingxubevange ye-Tungsten:Ikakhulukazi yakhiwe nge-tungsten, insimbi, i-nickel nezinye izinsimbi, ezinokuqina okuphezulu, amandla aphezulu, indawo encibilikayo ephezulu nezinye izici, ezivame ukusetshenziswa ekwenzeni i-aerospace kanye nezingxenye zokuzivikela kazwelonke ezisezingeni eliphezulu.
Izinto ezihlanganisiwe zedayimane: Idayimane njengengxenye eyinhloko yezinto ezibonakalayo, ngenqubo ye-sintering nezinye izinto zensimbi eziyinhlanganisela, inobunzima obuhle kakhulu, ukuqhutshwa kokushisa okushisayo, isetshenziswa kabanzi ku-abrasive, cutting, electronics, energy kanye neminye imikhakha.
I-Nano Ceramic composite material: eyakhiwe ngezinto zensimbi, ama-oxides, njll., enamandla amakhulu, ukuqina okuphezulu, ukumelana nokugqoka okuphezulu nokuzinza kokushisa okuphezulu, okufanelekile ukusika ngesivinini esikhulu, ukushisa okuphezulu kwe-sintering, amadivaysi kagesi kanye nezinye izinkambu.
Ngaphezu kwalokho, izinto zensimbi ze-sintered zihlanganisa izinhlobonhlobo zama-alloys akhethekile, izinto ezihlanganisiwe ze-ceramic kanye nezinto zensimbi ze-nano.
