Ukwelashwa kokushisa kuyinqubo ebalulekile ekukhiqizeni izimboni.Kubandakanya ukufudumeza nokupholisa izingxenye zensimbi ukuze kuthuthukiswe izakhiwo zazo zemishini, njengokuqina, ukuqina nokumelana nokugqoka.Nokho, akuzona zonke izindlela zokwelapha ukushisa ezidalwe zilingana.Ezinye zingabangela ukuwohloka ngokweqile noma ngisho kulimaze izingxenye.Yilapho kungene khona iziko lokucisha umoya we-vacuum.
I-vacuum air quenching isithando somliloiwuhlobo lwemishini yokwelapha ukushisa, esebenzisa igesi enomfutho ophezulu ukushisa izingxenye ku-vacuum bese izipholisa.Ivacuum yenzelwa ukuvimbela noma yikuphi ukufakwa kwe-oxidation noma ukungcoliswa ukuthi kwenzeke, futhi igesi (imvamisa i-nitrogen noma i-helium) isetshenziselwa ukucisha ingxenye ngokushesha nangokulinganayo.
I-vacuum quenching ibhekwa njengenye yezindlela ezingcono kakhulu zokufinyelela ibhalansi engcono kakhulu yokuqina nokuqina ezingxenyeni zensimbi.Ikhiqiza i-microstructure enhle ngaphandle kwe-surface decarburization noma ukuguqulwa, okuholela ezicini ezinhle kakhulu zemishini nempilo yesevisi ende.Ukwengeza, izithando zomlilo ezivala i-vacuum zingakwazi ukuphatha izinhlobonhlobo zezinto zokwakha, kusukela kunsimbi nensimbi engagqwali kuya ku-aluminium nama-titanium alloys.
Ukuze uthole izinzuzo ezigcwele zokuqiniswa kwe-vacuum, udinga okuthembekile, okuphumelelayoi-vacuum yokucisha isithando somlilo.Isitofu esihle kufanele sibe nalezi zimpawu ezilandelayo:
- Ivacuum ephezulu: Ngokufanelekile, isithando somlilo kufanele sikwazi ukufeza i-vacuum engu-10^-5 Torr noma ephansi ukuze kuncishiswe i-oxidation nokungcola.
- Ukucima ngokushesha: isithando somlilo kufanele sikwazi ukupholisa ingxenye ku-10-50 ° C / s ukuze kuzuzwe i-microstructure oyifunayo.
- Ukusabalalisa izinga lokushisa okulinganayo: Isithando somlilo kufanele sibe nesistimu yokushisisa eklanywe kahle esabalalisa ukushisa ngokulinganayo kuso sonke isithando somlilo ukuze kuqinisekiswe imiphumela engaguquki yokucisha.
- Uhlelo lokulawula oluthuthukisiwe: Isithando somlilo kufanele sibe nephaneli yokulawula esebenziseka kalula evumela ukulawulwa okunembile kwezinga lokushisa nokugeleza kwegesi, kanye nokuqapha nokurekhodwa kwedatha yenqubo.
At I-Paijinsinikeza ububanzi obubanzi bamaziko okucisha i-vacuum ahlangabezana nalezi zidingo nokunye okwengeziwe.Izithando zethu zomlilo ziklanywe futhi zakhiwa kusetshenziswa ubuchwepheshe bamuva nezinto zokwakha yiqembu elinolwazi lonjiniyela nochwepheshe.Siphinde futhi sinikeze izixazululo ezenziwe ngokwezifiso ukuhlangabezana nezidingo zakho ezithile kanye nezidingo.
Amanye amamodeli ethu aziwa kakhulu afaka:
- Isithando somlilo sokucisha i-vacuum esimile: isithando somlilo singakwazi ukuphatha izingxenye ezifika ku-2000mm ubude kanye nesisindo esingu-1500kg, nezinga lokushisa eliphakeme elingu-1350°C kanye nezinga lokupholisa ngokushesha elingu-30°C/s.
- Isithando somlilo esivundlile se-vacuum esicisha umoya: Lesi sithando somlilo singakwazi ukucubungula izingxenye ezinobukhulu obungu-1000mm nesisindo esingu-1000kg, nezinga lokushisa eliphakeme elingu-1350°C kanye nezinga lokupholisa ngokushesha elingu-50°C/s.
- Isithando somlilo se-Multi-purpose vacuum: Lesi sithando somlilo singasetshenziselwa izinqubo ezahlukene zokwelapha ukushisa ezifanaukucisha i-vacuum, ukufudumala, ukuthungatha, ukubhula, njll., ngezinga lokushisa eliphakeme lika-1300 ° C kanye ne-vacuum degree engu-10^ -5 Torr.
Sengiphetha, izithando zokucima umlilo ze-vacuum ziyithuluzi elibalulekile lokuthola imiphumela yekhwalithi ephezulu kanye nemiphumela engaguquki yokwelashwa kokushisa.Banikeza ukusebenza okuphezulu, ukusebenza kahle kanye nokuguquguquka uma kuqhathaniswa nezinye izindlela zokwelapha ukushisa.Uma ufuna isithando somlilo esithembekile nesisebenza kahle, hlola uhla lwe-Paijin lwe-Vacuum Air Quenching Furnaces namuhla!
