Isingeniso somkhiqizo

Lezi leli le-vacuum tungsten filament furnace liyisistimu esezingeni eliphezulu se-vacuum esezingeni eliphezulu ehlangana kakhulu nemvelo ye-vacuum nobuchwepheshe bokushisa obuphezulu kakhulu, isebenzisa i-high-purity tungsten wire mesh njengomthombo wokushisa, ihambisana nesakhiwo sokushisa esingamelana nokushisa esenziwe ngezinto eziningi ze-tungsten-molybdenum, ayina-carbon ngaphakathi, iqeda inkinga yokungcola kwe-carbon kusukela ekuqaleni. Umzimba we-furnace usebenzisa isakhiwo esiphindwe kabili se-stainless steel esipholiswe ngamanzi, esenziwe ngesibuko, isivinini esiphezulu se-vacuum singafinyelela ku-10⁻⁴ Palevel (i-molecular pump ephezulu ingafakwa kuze kufike ku10⁻⁵ ~ 10⁻⁶ Pa ), izinga lokushisa eliphezulu lokusebenza lingafinyelela ku-2300 ~ 2400℃. Le mishini ihlanganisa i-vacuum, ukuvikelwa kwesimiso, kanye ne-high-temperature sintering, inesakhiwo esihle, ukusebenza okuphephile, nokulawulwa kwezinga lokushisa okunembayo. Isetshenziswa kabanzi ku-powder metallurgy, i-functional ceramics, i-transparent ceramics, i-refractory metal alloys, nezinye izinqubo ze-high-temperature vacuum sintering zezinto ezintsha. Kuyisinqumo esihle kakhulu semishini yokuthuthukiswa kwezinto ezisezingeni eliphezulu emalabhorethri kanye nokukhiqizwa okuncane ezinkampanini.

Izici zobuchwepheshe

Izinga lokushisa eliphezulu kakhulu kanye ne-vacuum ephezulu: Izinga lokushisa eliphezulu lingafinyelela ku2300 ~ 2400℃, izinga lokugcina le-vacuum lingafinyelela≤6.67×10⁻⁴ Pa(i-furnace engenalutho, ebandayo), ingakhetha ipompo ye-molecular ukukhuphula i-vacuum kuya ku6×10⁻⁵Pa ~ 5×10⁻⁶ Pa, ihlangabezana nezidingo zokushisa ze-ultra-high vacuum.

Ukushisa okungenalo khabhoni nokuhlanzekile: Izinto zokushisa zisebenzisa izintambo eziphakeme kakhulu ze-tungsten/I-tungsten mesh, ayina-carbon ngaphakathi, iqeda ngokuphelele inkinga yokushintsha kwe-carbon nokungcola kwe-carbon okujwayelekile kwe-graphite furnace, ikakhulukazi ifanele ukushisa kwe-high-purity ceramic ne-transparent ceramic.

Ukusebenza kahle kokushisa nokufana kwezinga lokushisa: isakhiwo sokushisa se-tungsten cage net esinezinkanyezi ezintathu, indawo enkulu yokukhiqiza ukushisa, ukufana kwezinga lokushisa kungafinyelela ku-±3 ~ 5℃(1200℃Ngaphezu kwalokho); ihambisana nomklamo wokulawula izinga lokushisa elizimele wezindawo eziningi, iqinisekisa ngempumelelo ukufana kwendawo yokushisa endaweni yokusebenza.

Isikrini sokupholisa insimbi esendlalelwe izendlalelo eziningi: Uhlelo lokugcina ukushisa lusebenzisa isakhiwo sesikrini sokubonisa insimbi esendlalelwe izendlalelo eziningi, kusuka ngaphakathi kuya ngaphandle yizikrini ze-tungsten eziphakeme kakhulu, izikrini ze-molybdenum eziphakeme kakhulu, nezikrini zensimbi engagqwali ezendlalelwe izendlalelo eziningi, ukulahlekelwa okuncane kakhulu kokushisa, isivinini esisheshayo sokukhuphuka, ukonga amandla uma kuqhathaniswa ne-graphite furnace yakudala30%Ngaphezu kwalokho.

Isakhiwo esiphindwe kabili esipholiswe ngamanzi: Umzimba we-furnace usebenzisa isakhiwo esiphindwe kabili sensimbi engagqwali esipholiswe ngamanzi, ingaphandle liyatsheka, futhi uhlelo lokujikeleza okupholisa luqinisekisa ngempumelelo ukuthi izinga lokushisa langaphandle lezinto zokusebenza liyi-40 ~ 60℃, kuphephile futhi kuthembekile.

OkuhlakaniphilePIDUkulawulwa kwezinga lokushisa: Kuhlome ngesishintshi sokulawula izinga lokushisa esingenisiwe (njenge-Eurotherm3204/3504) nomaPLC + Uhlelo lokulawula isikrini sokuthinta, ukunemba kokulawula izinga lokushisa±1℃, inokulawula uhlelo lwezinga lokushisa lezigaba eziningi, ukuzilungisa, ukushisa ngokweqile/I-thermocouple/Ukwedlula kwamanje/imisebenzi yokuvikela i-water pressure interlock alarm.

Indawo yokusebenza ehlukahlukene: Isekela i-vacuum sintering kanye ne-atmosphere protection sintering (ingagcwaliswa nge-nitrogen, i-argon, i-hydrogen, i-nitrogen-hydrogen mixture, njll.), ingcindezi yokugcwalisa ≤0.05 MPa, ivumela ukuzivumelanisa kalula nezinqubo ezahlukene zezinto.

Qaphela: Izinhlobo ezahlukahlukene zezifudumezi zokuhlola kanye nezifudumezi zezimboni zingakwazi ukwenziwa ngokwezifiso ngokuya ngezimo zangempela zamakhasimende.

Izindawo zokusebenzisa

Ukubilisa kwe-ceramic esobala:YAGI-ceramic esobala, i-alumina ceramic esobala, i-magnesium aluminum spinel ceramic esobala, njll. iyaboshwa ngokuqinile ku-vacuum ephezulu kakhulu ukuze kutholwe ukudluliswa kokukhanya okuphezulu nokusebenza okuhle komshini.

Izikhungo zocwaningo namalabhorethri asezingeni eliphezulu: ukuthuthukiswa kwezinto ezintsha, ukuqinisekiswa kwenqubo, ukubonisa okufundisayo nokukhiqizwa okulinganiselwe.

Izinzuzo

Indawo ehlanzekile ye-ultra-high temperature: Ukushisa kwenethiwekhi ye-tungsten kuhlanganiswe nomklamo ongenayo i-carbon, uhlangabezana2000℃izidingo zokwelashwa kwezinga lokushisa eliphezulu kakhulu ngenkathi kugwenywa ukungcola kwekhabhoni, kuqinisekiswa ikhwalithi ye-sintering yezinto eziphakeme kakhulu.

Ukuhlanzeka okuphezulu kwe-vacuum ephezulu: Izinga lokugcina le-vacuum lifinyelela10⁻⁴ PaUbukhulu, uvimbele ngempumelelo ukubola kwezinto, ukukhipha umoya ngokuphelele, ikakhulukazi ifanele ukwelashwa kwezinto eziyigugu ezidinga ukuhlanzeka okuphezulu kakhulu.

Ukufana kokushisa okuhle kakhulu: isakhiwo sokushisa se-tungsten net esizungezile esinezinhlangothi ezintathu kanye nesikrini sokubonisa insimbi esendlalelwe izendlalelo eziningi, ukushisa kwezinga lokushisa kulawulwa ku-±3 ~ 5℃ngaphakathi, kuthuthukisa kakhulu ukungaguquguquki kwe-sintering yesampula.

Ukonga amandla nokunciphisa ukusetshenziswa: Isakhiwo sesikrini sokubonisa insimbi sinomsebenzi wokusebenzisa amandla aphezulu, ukulahlekelwa okuncane kokushisa, ukonga amandla uma kuqhathaniswa ne-furnace yokushisa ye-graphite yakudala30%ngaphezu kwalokho, izindleko zokusebenza ziphansi.

Ukulawulwa okuhlakaniphile kanye nokuvikelwa okuphephile okuningi:PLC + Uhlelo lokulawula isikrini sokuthinta, olusekela ukusebenza okuzenzakalelayo okugcwele ngokuchofoza okukodwa, futhi lunemithamo eminingi yezinyathelo zokuvikela ezifana ne-alarm yokushisa ngokweqile, ukuvikelwa kokunqamuka kokuphambanisa, ukuvikelwa okweqile kwamanje, nokuqapha ingcindezi yamanzi, ukuqinisekisa ukusebenza okuphephile nokuzinzile kwezinto zokusebenza.

Uzakuzenzela futhi kulula ukugcinwa: Umzimba we-furnace usebenzisa isakhiwo esiqondile, esithatha indawo encane, futhi umklamo ophindwe kabili opholiswe ngamanzi uthuthukisa ukuqina nokusebenza kwemishini; umshini wokulayisha ophansi ophansi wenza ukulayisha nokukhipha amasampula kube lula futhi kusebenze kahle.

Imisebenzi eguquguqukayo, ukwandiswa okuqinile: Ingakhetha ngokuguquguqukayo i-molecular pump, uhlelo olusheshayo lokupholisa, i-flow meter yezinto eziningi (MFC) uhlelo lokulawula ukuxubana kwegesi njll., lunokunwetshwa okunamandla, lufanele izimo eziningi zenqubo kusuka ocwaningweni oluyisisekelo kuya ekukhiqizeni okulinganiselwe.
