Ukwelashwa ngokushisa kuyinqubo ebalulekile ekukhiqizweni kwezimboni. Kuhilela ukushisa nokupholisa izingxenye zensimbi ukuze kuthuthukiswe izakhiwo zazo zemishini, njengokuqina, ukuqina kanye nokumelana nokuguguleka. Kodwa-ke, akuzona zonke izindlela zokwelashwa ngokushisa ezidalwe zilingana. Ezinye zingabangela ukuguquka ngokweqile noma zilimaze izingxenye. Yilapho izitofu zokucima umoya we-vacuum ziqala khona ukusebenza.
Isithando sokucima umoya se-vacuumuhlobo lwemishini yokwelapha ukushisa, esebenzisa igesi enomfutho ophezulu ukushisa izingxenye ku-vacuum bese izipholisa. Kudalwa i-vacuum ukuvimbela noma yikuphi ukungcoliswa noma ukushiswa, futhi igesi (ngokuvamile i-nitrogen noma i-helium) isetshenziswa ukucima ingxenye ngokushesha nangokulinganayo.
Ukucima i-vacuum kubhekwa njengenye yezindlela ezinhle kakhulu zokufeza ibhalansi engcono kakhulu yokuqina nokuqina ezingxenyeni zensimbi. Kukhiqiza isakhiwo esincane esihle ngaphandle kokususwa kwekhabhoni noma ukuguqulwa, okuholela ezicini ezinhle kakhulu zemishini kanye nokuphila isikhathi eside kwenkonzo. Ngaphezu kwalokho, izitofu zokucima i-vacuum zingaphatha izinto ezahlukahlukene, kusukela ensimbini nasensimbi engagqwali kuya ku-aluminium kanye ne-titanium alloys.
Ukuze uthole izinzuzo ezigcwele zokuqinisa i-vacuum, udinga i-vacuum harding ethembekile nesebenzayo.isithando sokucima i-vacuumIsitofu esihle kufanele sibe nezici ezilandelayo:
- I-vacuum ephezulu: Okungcono kakhulu, isithando somlilo kufanele sikwazi ukufinyelela i-vacuum engu-10^-5 Torr noma ngaphansi ukuze kuncishiswe ukungcoliswa kanye nokungcola.
- Ukucima okusheshayo: isithando somlilo kufanele sikwazi ukupholisa ingxenye ku-10-50°C/s ukuze kufezwe isakhiwo esincane esifunekayo.
- Ukusatshalaliswa kwezinga lokushisa elifanayo: Isithando somlilo kufanele sibe nohlelo lokushisa oluklanywe kahle olusabalalisa ukushisa ngokulinganayo kulo lonke isithando somlilo ukuqinisekisa imiphumela yokucima ehambisanayo.
- Uhlelo lokulawula oluthuthukisiwe: Isithando somlilo kufanele sibe nephaneli yokulawula elula ukuyisebenzisa evumela ukulawula okunembile kokushisa nokugeleza kwegesi, kanye nokuqapha nokuqopha idatha yenqubo.
At I-PaijinSinikeza izinhlobo eziningi zezitofu zokucima i-vacuum ezihlangabezana nalezi zidingo nokuningi. Izitofu zethu zaklanywa futhi zakhiwa kusetshenziswa ubuchwepheshe bamuva nezinto zokwakha yithimba lonjiniyela nochwepheshe abanolwazi. Siphinde sinikeze izixazululo ezenziwe ngokwezifiso ukuze zihlangabezane nezidingo zakho ezithile.
Amanye amamodeli ethu athandwa kakhulu afaka:
- Isithando somlilo esivala umoya esiqondile: isithando somlilo singaphatha izingxenye ezifika ku-2000mm ukuphakama kanye nesisindo esingu-1500kg, kanye nokushisa okuphezulu okungu-1350°C kanye nesivinini sokupholisa esisheshayo esingu-30°C/s.
- Isithando somlilo esivala umoya esivundlile: Lesi sithando somlilo singacubungula izingxenye ezinobubanzi obungu-1000mm kanye nesisindo esingu-1000kg, kanye nokushisa okuphezulu okungu-1350°C kanye nesivinini sokupholisa esisheshayo esingu-50°C/s.
- Isithando somlilo esinomshini wokuhlanza esisetshenziswa ngezindlela eziningi: Lesi sithando somlilo singasetshenziselwa izinqubo ezahlukene zokwelapha ukushisa ezifanaukucima i-vacuum, ukufudumala, ukupholisa, ukupholisa, njll., ngezinga lokushisa eliphezulu lika-1300°C kanye nezinga le-vacuum elingu-10^-5 Torr.
Ekuphetheni, izitofu zokucima umoya nge-vacuum ziyithuluzi elibalulekile lokufeza imiphumela yokwelashwa kokushisa esezingeni eliphezulu neqhubekayo. Zinikeza ukusebenza okuphezulu, ukusebenza kahle kanye nokuguquguquka uma kuqhathaniswa nezinye izindlela zokwelapha ukushisa. Uma ufuna isitofu esithembekile nesisebenzayo, hlola uhla lwe-Paijin lwe-Vacuum Air Quenching Furnaces namuhla!
