Chii chinonzi Sintered metal parts:
Sintered metal parts inogadzirwa uchishandisa aupfu metallurgy nzira inonzi sintering. Nenzira iyi, hupfu hwesimbi hunomanikidzwa kuita chimiro chaihwo, uye ipapo kupisa kunoshandiswa kubatanidza zvimedu zvesimbi mukati mechinhu chakasikwa, zvichiita kuti chichengetedze chimiro chayo chitsva.Sinteringinogona kushandiswa kugadzira huwandu hwakawanda hwesimbi chikamu mhando uye inowirirana nesimbi dzakawanda dzakasiyana uye alloys.
JIEHUANGSintered Metals inyanzvi mukucheka-kumucheto sintering maitiro anoshandura simbi dzehupfu kuita dzakasimba, dzakavimbika zvigadzirwa zvesimbi. Dzidza zvakawanda nezve simbi sintering maitiro uye kuti ingabatsire sei application yako nekuverenga.
Chii chinonzi sintering process:
Sintering process ndeyekugadzira iron ore poda, flux, mafuta uye zvinotsiva zvinoenderana nezvinodiwa zvekuputika kwechoto kunyungudika, maererano neimwe chikamu chekubatisa, kusanganisa, kuwedzera kunhuhwirira kwemvura. Regranulation, kugovera kupisa, nerubatsiro rwe fan, kuitira kuti pasi pekuita kweimwe tembiricha yakakwira, pamusoro peimwe iron ore poda kupfava uye kunyunguduka, inoburitsa imwe nhanho yemvura, uye imwe yekupedzisira kunyunguduka ore zvimedu, mushure mekutonhora, chikamu chemvura chinonamira mamineral poda zvimedu muzvivharo maitiro aya ari kunyungudika.
The basic sintering process
kudzvanya hupfu → kuchaja (kugadzirira usati warodha uye kunyura) → sinter (preheating, kuchengetedza kupisa uye kutonhora) → kubuda → sintered body
Ndezvipi zvakanakira Sintered simbi zvikamu?
● Kuburikidza ne sintering, high quality sinter ine stable chemical composition, uniform particle size, good reducibility uye high metallurgical performance inogona kupiwa kuputika kwevira, iyo inogadzira mamiriro ezvinhu akanaka emhando yepamusoro, kukohwa kukuru, kushandiswa kwakaderera uye hupenyu hurefu.
● Inogona kubvisa tsvina inokuvadza yakadai sesarufa, zinc, nezvimwewo;
● Kuraswa kwemaindasitiri, senge blast furnace dust, rolled steel, sulfuric acid slag, steel slag, nezvimwewo;
● Masimbi asina ferrous neare earth metals anogona kuwanikwazve.

Ndezvipi zvakajairika sintered simbi zvinhu:
Hard alloy: inoumbwa ne tungsten, cobalt, kabhoni uye mamwe masimbi, ane kuomarara kwakanyanya, kusimba kwekusapfeka kwakasimba, kusadzivirirwa nekuora uye zvimwe zvivakwa, zvinoshandiswa zvakanyanya mukugadzira, migodhi nemimwe minda.
Tungsten alloy:Inonyanya kuumbwa ne tungsten, iron, nickel nedzimwe simbi, ine hupamhi hwepamusoro, simba guru, nzvimbo yakanyanyisa yakanyunguduka uye humwe hunhu, hunowanzo shandiswa mukugadzirwa kweaerospace uye nyika kudzivirira kwepamusoro-tembiricha zvikamu.
Diamond inoumbwa zvinhu: Dhaimondi sechinhu chikuru chechikamu zvinhu, kuburikidza nesintering processuye zvimwe zvinhu zvesimbi zvinoumbwa, zvine kuomarara kwakanyanya, kupisa conductivity, kunoshandiswa zvakanyanya muabrasive, kucheka, zvemagetsi, simba uye mamwe minda.
Nano ceramic composite zvinhu: inoumbwa nesimbi, oxides, nezvimwewo, ine simba rakawanda, kuomarara kwepamusoro, kushomeka kwepamusoro uye kugadzikana kwekushisa kwakanyanya, kwakakodzera kucheka kwekukurumidza, kupisa kwakanyanya sintering, zvigadzirwa zvemagetsi nemimwe minda.
Mukuwedzera, sintered simbi zvinhu zvinosanganisirawo akasiyana akakosha alloys, ceramic composite zvinhu uye nano simbi zvinhu.
Kukubatsira kuti unzwisise zvirinani sintered metal materials, ndagadzira tafura ine udzame inoronga mhando dzakasiyana dzesintered simbi zvinhu uye zvine chekuita nazvo.
