Vacuum air quenching ng'anjo: chinsinsi chothandizira kutentha kwapamwamba

Kuchiza kutentha ndi njira yofunikira pakupanga mafakitale.Zimaphatikizanso kutenthetsa ndi kuziziritsa zitsulo kuti zithandizire kukonza makina awo, monga kuuma, kulimba komanso kukana kuvala.Komabe, si mankhwala onse otentha omwe amapangidwa mofanana.Zina zimatha kuyambitsa mapindikidwe ambiri kapena kuwononga ziwalo.Apa ndi pamene ng'anjo zozimitsa mpweya wa vacuum zimayambira.

Vacuum mpweya kuzimitsa ng'anjondi mtundu wa zida zochizira kutentha, zomwe zimagwiritsa ntchito mpweya wothamanga kwambiri kutenthetsa mbali mu vacuum kenako kuziziziritsa.Vacuum imapangidwa kuti iteteze kutulutsa kwa okosijeni kapena kuipitsidwa kulikonse, ndipo mpweya (kawirikawiri nayitrogeni kapena helium) umagwiritsidwa ntchito kuzimitsa gawolo mwachangu komanso mofanana.

Kuzimitsa vacuum kumaonedwa kuti ndi imodzi mwa njira zabwino kwambiri zopezera kulimba kwabwino komanso kulimba m'zigawo zachitsulo.Zimapanga microstructure yabwino popanda decarburization kapena mapindikidwe, zomwe zimapangitsa kuti zikhale zabwino kwambiri zamakina komanso moyo wautali wautumiki.Kuonjezera apo, ng'anjo zozimitsa zowonongeka zimatha kugwiritsa ntchito zipangizo zosiyanasiyana, kuchokera kuzitsulo ndi zitsulo zosapanga dzimbiri mpaka aluminium ndi titaniyamu.

Kuti mupindule mokwanira ndi kuuma kwa vacuum, mukufunikira odalirika, ogwira ntchitovacuum kuzimitsa ng'anjo.Chitofu chabwino chiyenera kukhala ndi makhalidwe awa:

- Vuto lalikulu: Moyenera, ng'anjoyo iyenera kukhala ndi mpweya wa 10 ^ -5 Torr kapena kutsika kuti muchepetse okosijeni ndi kuipitsidwa.

- Kuzimitsa mwachangu: ng'anjoyo iyenera kuziziritsa gawolo pa 10-50 ° C / s kuti mukwaniritse microstructure yomwe mukufuna.

- Kugawa kwa kutentha kofanana: Ng'anjoyo iyenera kukhala ndi makina otenthetsera opangidwa bwino omwe amagawa kutentha mofanana mu ng'anjo yonse kuti awonetsetse kuti kuzimitsa kosasinthasintha.

- Dongosolo lapamwamba lowongolera: Ng'anjoyo iyenera kukhala ndi gulu lowongolera lomwe limalola ogwiritsa ntchito kutentha komanso kuyendetsa bwino kwa gasi, komanso kuyang'anira ndi kujambula zomwe zachitika.

At Paijintimapereka ng'anjo zambiri zozimitsa vacuum zomwe zimakwaniritsa zofunikira izi ndi zina zambiri.Ng'anjo zathu zidapangidwa ndikumangidwa pogwiritsa ntchito ukadaulo waposachedwa ndi zida ndi gulu lodziwa zambiri la mainjiniya ndi akatswiri.Timaperekanso njira zothanirana ndi zomwe mukufuna komanso zomwe mukufuna.

Zina mwa zitsanzo zathu zodziwika bwino ndi izi:

- Mng'anjo yozimitsa mpweya woyima: ng'anjoyo imatha kunyamula magawo mpaka 2000mm kutalika ndi 1500kg kulemera, ndi kutentha kwakukulu kwa 1350 ° C ndi kuzizira kofulumira kwa 30 ° C / s.

- Ng'anjo yozimitsa mpweya yopingasa: Ng'anjoyi imatha kupangira magawo okhala ndi mainchesi 1000mm ndi kulemera kwa 1000kg, kutentha kwambiri kwa 1350 ° C ndi kuzizira kofulumira kwa 50 ° C / s.

- Ng'anjo yovumbula yamitundu ingapo: Ng'anjo iyi imatha kugwiritsidwa ntchito popangira njira zosiyanasiyana zochizira kutentha mongakuchotsa vacuum, kutentha, kutsekemera, kutsekemera, etc., ndi kutentha kwakukulu kwa 1300 ° C ndi digiri ya vacuum ya 10 ^ -5 Torr.

Pomaliza, ng'anjo zozimitsa mpweya wa vacuum ndi chida chofunikira chopezera zotsatira zamankhwala apamwamba komanso osasinthasintha.Amapereka ntchito zapamwamba, zogwira mtima komanso zosinthika poyerekeza ndi njira zina zochizira kutentha.Ngati mukuyang'ana ng'anjo yodalirika komanso yothandiza, onani Paijin's Vacuum Air Quenching Furnaces lero!
