Yini izingxenye zensimbi ze-Sintered:
Izingxenye zensimbi ezenziwe nge-sintered zenziwe kusetshenziswa aindlela ye-powder metallurgy ebizwa nge-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-Sinteringingasetshenziswa ukukhiqiza izinhlobo eziningi zezingxenye zensimbi futhi iyahambisana nezinsimbi eziningi ezahlukene kanye nama-alloys.
I-JIEHUANGI-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, ukushisa 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 ze-ore, emva kokupholisa, isigaba se-liquid sizonamathela izinhlayiya ze-mineral powder zibe amabhlogo le nqubo 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 ?
● Ngokucwilisa, i-sinter yekhwalithi ephezulu enokwakheka kwamakhemikhali okuzinzile, usayizi wezinhlayiyana ezifanayo, ukunciphisa okuhle nokusebenza kwe-metallurgical okuphezulu kungahlinzekwa ku-blast furnace, okudala izimo ezinhle zekhwalithi ephezulu, isivuno esiphezulu, ukusetshenziswa okuphansi nempilo ende.
●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.
