Imvamisa yesiphakathi esiphakathi eshaya izitini eziphefumulayo

Igama lomkhiqizo:

Isitini esiphefumulwayo ngokushaya phansi kwesithando semvamisa esiphakathi

Isigaba: Izitini Eziphefumulekayo Zokushayiswa Ngaphansi Kwesithando Somlilo Esivamile Esiphakathi

Imininingwane yomkhiqizo

Ukusebenza okuphezulu kwezinga lokushisa kwezitini zokushaya phansi kwesithando samandla amaphakathi ikakhulu kuncike ekwakhiweni komzimba, kwamakhemikhali nokwakhiwa kwamaminerali kwezinto ezisetshenziswayo ezisetshenziswayo. UTongyao ungumphakeli wezinto zokwakha ezisenkingeni zomkhakha, futhi ukukhiqizwa kwezitini eziphehla umoya zokufutha ezansi kwamakhaza amaphakathi amaphakathi kusetshenziswe kabanzi. uhlelo lokusebenza.

Ukusetshenziswa Kobuningi Bokuphefumula Izitini Obuphefumula Esithombeni Somlilo Esetshenziswa Ngokujwayelekile

Ngokusebenzisa izitini ezingena emoyeni, sifingqe ubuchwepheshe obuphakathi bokuvulwa kwesithando esiphakathi nendawo, esiguqule isithando somlilo esivamile esiphakathi nendawo sisuka “ekhemikhali lensimbi” senziwa insimbi. Ezimweni eziningi, ikhwalithi yensimbi encibilikisiwe (taijin) ifinyelele esithandweni se-AOD naseLF yokucwilisa isithando somlilo. , Izinga lekhwalithi yokuhlanza isithando somlilo se-VD.

Irhasi edingekayo (efana ne-high-purity argon) ithunyelwa ensimbi encibilikisiwe ngesitini esingenwa ngumoya, futhi ngemuva kwenani elithile nesikhathi sokugeleza, ukufakwa (okufana neSio2, Al2O3, MgO, njll.) kuncishisiwe. Futhi okuqukethwe u-O】 O 【N】 【H,, kunezidingo ezikhethekile ezinjengokuthi uma ususa amandla okwengeza, ungashaya igesi ehlanganisiwe ye-argon / oxygen, enganciphisa okuqukethwe kwekhabhoni ebangeni elithile, lapho uhlangana nensimbi ene-nitrogen, ushaya nge-nitrogen kungaba Yandisa i-ammonia.

Isimiso sokusebenza Inqubo yokucwenga ngokushaya igesi ye-argon esithandweni sokungeniswa ngemuva kokuba insimbi encibilikile incibilikile. Ngemuva kokuthi i-pre-deoxygenation isiqediwe, ngemuva kokusampula nokuhlaziya, igesi ephezulu ye-argon ingeniswa ensimbi encibilikisiwe ngesitini esingena umoya esifakwe ezansi kwesithando somlilo. Lapho igesi ye-argon idlula esitinjini esingena umoya, inesilinganiso esiphakeme sokuhlakazeka, yakha inhlayiyana encane enejubane elikhudlwana lokukhuphuka. Ukugeleza kwe-bubble, amabhamuza angenakubalwa adlula ensimbi encibilikisiwe azokhiqiza umphumela wokucwengwa. Ibhamu ngalinye le-argon elingaphakathi kwensimbi encibilikisiwe liyigumbi elincane le-“vacuum”, kanti i-H, O, N namanye amagesi awaqukethwe kubhamuza lwe-argon. Lokho ukusho ukuthi, ingcindezi ngokwengxenye yalezi gesi ku-bubble ye-argon ilingana no-zero. Lapho i-bubble ye-argon enengcindezi ephezulu ngokwengxenye idlula ngensimbi encibilikisiwe, i- [H] [O] [N] encibilikisiwe kanye ne-c0 engancibiliki izongena nge-othomathikhi kubhamu ye-argon bese ilandela i-bubble Rise and overflow. Ukuze kufezwe inhloso ye-degassing.

Ngemuva kokucwengwa, ikhwalithi nokuhlanzeka kwensimbi kuthuthukiswa kakhulu, ukungafani kokufakwa ngaphambi nangemva kokucwengwa kuncishiswe kakhulu, futhi okuqukethwe kwegesi kuncishiswe kakhulu. Isibonelo manje sifaniswa ngokulandelayo

1. Ukufaka

Into i-ABCD

I-Sulfide Alumina Silicate Ball oxide

Isilinganiso ngaphambi kokucwengwa 1.8 1.7 1.5 2.1

Isilinganiso ngemuva kokucwenga i-0.55 0.64 0.5 0.67

Ukwehliswa okuphakathi% 69 62 67 68

Imiphumela yesilinganiso yangempela ihlangabezana nezidingo zobuchwepheshe zezinga.

2. Okuqukethwe kwe-hydrogen kungaphansi kuka-1.0ppm, kuhlangabezana nezidingo zensimbi yokufa ≤2.5ppm, namanye amabanga wensimbi ≤3.0ppm.

3. Okuqukethwe kwe-oxygen kungaphansi kuka-0.0050%.

4. Ngemuva kokucutshungulwa kwe-ingot yensimbi, ukuhlolwa kwe-ultrasonic kufinyelele ezingeni lesibili le (GB / T13315-1991).

5. Ukuqhathanisa izakhiwo zomshini zensimbi engagqwali engu-304 ngaphandle nangaphandle kokucwengwa: (GB / T328-2002)

1) Amandla we-tensile angama-549.53Mpa ngaphambi kokucwengwa futhi i-606.82Mpa ngemuva kokucwengwa inyuswe ngo-57.29Mpa

2) Amandla wesivuno angama-270Mpa ngaphambi kokucwengwa futhi ama-339.52Mpa ngemuva kokucwengwa akhuphuke ngo-69.52Mpa

3) Phoqa u-38.46KN ngaphambi kokucwenga i-49.10KN ngemuva kokucwenga ukwanda ngo-10.64KN

Amanothi ambalwa:

a) Njengoba isikhathi sokushaywa kwe-argon esithandweni ngasinye sensimbi singu-5 ~ 10mm, ukushaywa kwe-argon kwenziwa ngemuva kokungeza iTaijin. Ngemuva kokushaya, ukuthepha insimbi ngeke kuthinte isikhathi sokuncibilikisa futhi ngeke kwandise ukusetshenziswa kwamandla.

b) Ukususwa kwe- [N] [H] [O] ngokushaya igesi ye-argon akubangeli ukusabela kwamakhemikhali, ngeke nje kuphela kunciphise impilo yesikhumba esimbozwe esithandweni somlilo, kepha ngokuphambene nalokho, impilo yesikhumba sesikhumba isithatha isikhathi eside ngenxa kuya homogenization lokushisa ncibilika esithandweni.

c) I-Argon iyigesi engokomzwelo futhi iphephe kakhulu ukuyisebenzisa.

Kafushane nje: Ubuchwepheshe bokucwiliswa kwesithando esiphakathi nendawo obumakishwe ngokusetshenziswa kwezitini ezivumela umoya kuyinqubo yokukhiqiza enotshalo-mali oluphansi, ukufinyelela okusheshayo, izindleko eziphansi kanye nekhwalithi ephezulu. Kuyinqubo yokukhiqiza yokonga amandla futhi engasebenzisi imvelo kanye nenqubo yokukhiqiza ehamba kancane. Ngokuya ngalobu buchwepheshe, kuhlanganiswe nenqubo yokusakaza evikelayo, ukukhishwa kwekhwalithi ephezulu nemikhiqizo yensimbi kungakhiqizwa.
