Kuchiza kutentha kwa vacuum ndi ukadaulo wapamwamba wokonza zinthu womwe umaphatikiza ukadaulo wa vacuum ndi njira zamakono zokonzera kutentha. Mfundo yake yaikulu imaphatikizapo kuyika zida zogwirira ntchito pamalo otsika mphamvu ya mlengalenga—yopangidwa ndi kusamalidwa ndi makina ochotsera vacuum, omwe nthawi zambiri amakhala otsika mpaka okwera kwambiri—kuti azitha kutenthedwa, kunyowa, ndi kuzizira.
Poyerekeza ndi njira zachikhalidwe zochizira kutentha, kuchiza kutentha kwa vacuum kumapereka ubwino waukulu pa ubwino wa njira, kusamala chilengedwe, komanso kuwongolera katundu wa zinthu. Kuchitidwa kwathunthu kapena pang'ono mkati mwa vacuum, njirayi imatha kuchita ntchito zonse zochizira kutentha monga kuphimba, kuzimitsa, kutenthetsa, ndi kuwotcha. Chofunika kwambiri, chimakwaniritsa:
- Ukhondo Wopanda Oxidation ndi Wapamwamba:Malo osungira mpweya m'malo osungira mpweya amachotsa mpweya m'thupi, kuteteza kusungunuka kwa okosijeni, kuchotsedwa kwa mpweya m'thupi, kapena kusungunuka kwa mpweya m'malo ogwirira ntchito kutentha kwambiri. Amachotsanso mafuta pamwamba, mpweya wothira madzi, ndi zodetsa zina zotsala, zomwe zimapangitsa kuti malo owala komanso oyera asafunike kutsukidwa pambuyo pa ntchito.
- Kapangidwe ka Makina Olimbitsa:Kutenthetsa mu vacuum kumachepetsa kukhuthala kwa tirigu ndi kuchepa kwa zinthu, zomwe zimathandiza kulimbitsa zinthu, kulimba kwa kutopa, komanso kukana kuwonongeka.
- Kuwongolera Njira Molondola Kwambiri:Kusamutsa kutentha mu vacuum kumakhala kofanana komanso kowongoleredwa, zomwe zimathandiza kukonza zinthu zovuta komanso zolondola nthawi zonse.
- Ubwino Wogwiritsa Ntchito Mwanzeru Zachilengedwe ndi Mphamvu:Njirayi imachotsa kufunika kwa mlengalenga woteteza (monga nayitrogeni, argon) kapena mankhwala, zomwe zimachepetsa mpweya woipa komanso kugwiritsa ntchito zinthu zomwe zili m'mlengalenga.
M'mbuyomu, mayiko otukuka monga United States ndi Japan anali akatswiri pa malonda a vacuum heater. Kupita patsogolo pakupanga zida zozimitsira vacuum (monga mafuta ozimitsira vacuum ndi njira zogwiritsira ntchito madzi a polymer) kunathandiza kwambiri. Kupita patsogolo kumeneku kunathandiza kuti ukadaulowu usinthe kuchoka pa kuzima vacuum quenching wamba kupita ku njira zamakono monga kuzimitsira gasi wopanikizika kwambiri, kuzima vacuum carburizing, kuzima vacuum nitriding, ndi njira zambiri zofalitsira.
Pampu ya vacuum ndi makina ake osefera ndi zinthu zofunika kwambiri paukadaulo uwu:
- Pampu ya vacuum ili ndi udindo wopanga ndikusunga mulingo wofunikira wa vacuum.
- Thefyuluta ya pampu ya vacuumImateteza pampu ku kuwonongeka komwe kumachitika chifukwa cha zinthu zodetsa zomwe zimatulutsidwa panthawiyi, monga mafuta osungunuka, nthunzi zachitsulo, ndi fumbi, zomwe zimaonetsetsa kuti dongosololi likugwira ntchito bwino kwa nthawi yayitali komanso mokhazikika.
Masiku ano, pamene kupanga zinthu zapamwamba kumafuna ntchito yapamwamba kwambiri, ukadaulo wothira kutentha kwa vacuum ukupitilira kupita patsogolo kufika pamlingo wapamwamba wa vacuum, kuwongolera mwanzeru, komanso njira zotetezera chilengedwe. Chifukwa chake, zida zamachitidwe a vacuum ziyeneranso kusintha, zomwe zimafuna kuthamanga kwambiri, kudalirika kwambiri, komanso kugwira ntchito bwino.njira zoseferakukwaniritsa zofunikira zogwirira ntchito m'mafakitale zomwe zikuchulukirachulukira.
