Kodi Sintered metal parts ndi chiyani:
Zigawo zachitsulo za sintered zimapangidwa pogwiritsa ntchito aufa Metallurgy njira wotchedwa sintering. Mwa njira iyi, ufa wachitsulo umakanizidwa kukhala mawonekedwe enieni, ndiyeno kutentha kumagwiritsidwa ntchito kugwirizanitsa tinthu tachitsulo mkati mwa chinthu chopangidwa, kuti chikhalebe ndi mawonekedwe ake atsopano.Sinteringangagwiritsidwe ntchito kupanga osiyanasiyana zitsulo mbali mitundu ndipo n'zogwirizana ndi zitsulo zosiyanasiyana ndi kaloyi.
JIEHUANGSintered Metals ndi akatswiri panjira zotsogola zomwe zimasandutsa zitsulo za ufa kukhala zitsulo zolimba, zodalirika. Phunzirani zambiri za njira yopangira zitsulo komanso momwe ingathandizire pulogalamu yanu powerenga.
Kodi sintering process ndi chiyani:
Sintering ndondomeko ndi kukonzekera chitsulo ore ufa, flux, mafuta ndi m'malo malinga ndi zofunika kuphulika ng'anjo smelting, malinga ndi gawo lina la batching, kusakaniza, kuwonjezera mafuta kondomu. Regranulation, kugawa poyatsira, mothandizidwa ndi zimakupiza, kuti pansi pa zochita za ena kutentha pamwamba, pamwamba pa ena chitsulo chitsulo ufa kufewetsa ndi kusungunuka, kupanga ena madzi gawo, ndi ena omaliza kusungunuka particles ore, pambuyo yozizira, ndi madzi gawo adzakhala n'kudziphatika mchere particles ufa mu midadada ndondomeko sintering.
The Basic sintering ndondomeko
kukanikiza ufa → kulipiritsa (kukonzekera musanalowetse ndi sinter) → sintering (kutentha, kuteteza kutentha ndi kuziziritsa) → kutuluka → sintered thupi
Kodi maubwino a Sintered zitsulo ndi chiyani?
● Kupyolera mu sintering, sinter yapamwamba yokhala ndi mankhwala okhazikika, kukula kwa tinthu tating'onoting'ono, kuchepetsedwa kwabwino komanso zitsulo zamakono zimatha kuperekedwa kwa ng'anjo yophulika, yomwe imapanga mikhalidwe yabwino kwambiri, zokolola zambiri, zotsika mtengo komanso moyo wautali.
● Atha kuchotsa zonyansa zovulaza monga sulfure, zinki, ndi zina;
● Zinyalala zamafakitale, monga fumbi la ng'anjo yophulika, zitsulo zogubuduzika, sulfuric acid slag, slag yachitsulo, ndi zina zotero;
● Zitsulo zopanda chitsulo ndi zitsulo zosowa zapadziko lapansi zitha kupezedwanso.
Sintering kutentha osiyanasiyana Sintered zitsulo
| Sintering kutentha | Zitsanzo za zinthu za sintered |
| 1050 | Mkulu wa carbon (pamwamba pa 2.5% graphite), kachulukidwe kakang'ono ( |
| 1080 | Mafuta okwera kwambiri, chiwongolero cha valve, graphite zili ndi 1.5-2.5% zotsutsana ndi mikangano |

| ＞1150 | Zigawo zapakatikati komanso zolimba kwambiri (zolemba ma graphite |
Kodi Common sintered zitsulo ndi ziti:
Aloyi yolimba: zopangidwa ndi tungsten, cobalt, carbon ndi zitsulo zina, ndi kuuma kwambiri, amphamvu kuvala kukana, kukana dzimbiri ndi katundu zina, chimagwiritsidwa ntchito Machining, migodi ndi zina.
Tungsten alloy:Amapangidwa makamaka ndi tungsten, chitsulo, faifi tambala ndi zitsulo zina, ndi kachulukidwe mkulu, mphamvu mkulu, mkulu kusungunuka mfundo ndi makhalidwe ena, nthawi zambiri ntchito kupanga Azamlengalenga ndi chitetezo dziko mbali mkulu-kutentha.
Zinthu zopangidwa ndi diamondi: Diamondi monga chigawo chachikulu cha zinthu, kudzera mundondomeko ya sinteringndi zida zina zitsulo gulu, ali kuuma kwambiri, madutsidwe matenthedwe, chimagwiritsidwa ntchito abrasive, kudula, zamagetsi, mphamvu ndi zina.
Nano ceramic kompositi zakuthupi: zopangidwa ndi zitsulo zachitsulo, oxides, etc., ndi mphamvu yapamwamba, kulimba kwambiri, kukana kuvala kwapamwamba komanso kukhazikika kwa kutentha kwapamwamba, koyenera kudula mofulumira, kutentha kwa sintering, zipangizo zamagetsi ndi madera ena.
Kuphatikiza apo, zida zachitsulo za sintered zimaphatikizansopo mitundu yosiyanasiyana ya ma aloyi apadera, zida zophatikizika za ceramic ndi zida zachitsulo za nano.
Kuti ndikuthandizeni kumvetsetsa bwino zida zachitsulo za sintered, ndapanga tebulo latsatanetsatane lolemba mitundu yosiyanasiyana ya zitsulo za sintered ndi mawonekedwe ake.

6. Makampani a Mafuta ndi Gasi
Makampani amafuta ndi gasi amapindula ndi zinthu zachitsulo zosungunuka ngatizigawo zoseferandizigawo za valve. Zogulitsazi zapangidwa kuti zipirire kupanikizika kwakukulu ndi kutentha, ndi zipangizo zomwe zimapereka mphamvu zambiri komanso kukana dzimbiri.
7. Makampani amagetsi
M'makampani amagetsi, zitsulo za sintered zimagwiritsidwa ntchitoolumikizana nawo,ma terminals,ndimaginito zigawo.Sintered silver,mkuwa, ndi zipangizo zofewa za maginito zimakondedwa chifukwa cha khalidwe lawo labwino kwambiri, kukana kuvala, ndi maginito.
8. Zida ndi Die Viwanda
Makampani opanga zida ndi kufa amagwiritsa ntchito zitsulo za sinteredzida zodulira,nkhungu,ndiamafa.Sintered tungsten carbideamadziwika chifukwa cha kuuma kwake kwambiri komanso kukana kuvala, zomwe zimapangitsa kuti zikhale zoyenera kwa malo othamanga kwambiri komanso ovala kwambiri.
9. Zodzikongoletsera ndi Mafashoni
Sintered zitsulo, mongachitsulo chosapanga dzimbiri,titaniyamu,ndizitsulo zamtengo wapatali, ndi otchuka mu zodzikongoletsera ndi mafashoni polengazinthu zokongoletserandipenyani zigawochifukwa cha kukongola kwawo komanso kulimba kwawo.
10. Zida Zam'nyumba
Zigawo zazitsulo za sintered zimapezeka muzinthu zosiyanasiyana zapakhomo, mongacompressorsm'mafiriji ndi ma air conditioners, komansomasambandizidamu zosakaniza ndi zosakaniza. Zigawozi zimapindula ndi kulimba, kulimba, komanso kukana kwazitsulo za sintered.
