Imiqathango yokusebenza kwe emoyeni eziko emoyeni

I-vacuum atmosphere furnace luhlobo lwesithando somlilo esinokucocwa kwaye sinokudlula umoya. Ineendidi ezininzi ezahlukeneyo zeziko ezifana nohlobo lwebhokisi, isithando somlilo setyhubhu, kunye nesithando somlilo esiphakamisayo. Nangona zininzi iintlobo, izilumkiso ngexesha lokusebenza azikho zimbi. Ngezantsi masifumanise:

1. Iziko lobushushu obuphezulu lobushushu alinakugcwala kakhulu. Ubushushu obuphezulu bokusebenza bubhekisa kubushushu obuvumelekileyo bomphezulu bento kwi-vacuum, hayi ubushushu bezinto zokufudumeza okanye ubushushu obujikeleze into yokufudumeza. Kufuneka kuqatshelwe ukuba iqondo lokushisa le-vacuum yokufudumala i-vacuum ngokwayo liyi-100 ° C ngaphezu kokushisa kwendawo ejikelezileyo okanye ukushisa okutshisayo.

2. Xa ulinganisa ukufana kweqondo lokushisa kwesithando somlilo we-vacuum, nikela ingqalelo kwindlela yokumisa uqhagamshelwano lokulinganisa ubushushu kunye nomgama ovela kwindawo yokufudumala. Sebenzisa iibhrashi, imitshayelo okanye umoya ocinezelweyo, izicoci zokufunxa, njl. njl ukujikeleza, kunye nokutshisa iintonga zokufudumeza i-molybdenum. Ipleyiti esezantsi, intonga yokufudumeza i-molybdenum, i-furnace insulation layer kunye nezinye izinto zentsimbi ezikwazi ukumelana nobushushu kufuneka zicocwe rhoqo xa zisetyenziswa. Ukunkqonkqoza kunqatshelwe ngokungqongqo, kwaye isikali sabo se-oxide sinokususwa ngononophelo.

3. Emva kokuba isithando somlilo sishushu, inkqubo ye-vacuum ayinakutshatyalaliswa ngokukhawuleza, makungabikho ukuvula umnyango wesithando somlilo. Qaphela ukuba igeyiji yevacuum kufuneka icinywe phambi kokuba igcwalise umoya ukuthintela ukuguga kwevacuum. Xa iqondo lobushushu lingaphezulu kwe 400℃, kufuneka lingapholiswa ngokukhawuleza. Kuphephe ukusabela phakathi kwezinto zokufudumeza kunye neemveliso, ngakumbi ukuba ubhedu, i-aluminiyam, i-zinc, itoti, ilothe, njl.njl. zidibana nezinto zokufudumeza ngevacuum, nokuba ngumgubo ocolekileyo, ulwelo olutyhidiweyo okanye umphunga, njl. njl., ukunqanda ukhukuliseko kunye nokwakheka “imigodi” phezu kwendawo yokufudumala yombane. , I-cross-section iba yincinci, kwaye iyatshisa emva kokushisa. Xa iindawo zokuhambisa zifunyenwe zixinzelelwe, zingachanekanga kumda, kunye nokungaphumeleli kokulawula, kufuneka zipheliswe ngokukhawuleza, kwaye unganyanzeli umsebenzi ukuphepha umonakalo kwiindawo.

4. Amacandelo ensimbi ekwazi ukumelana nokushisa njengeplate engezantsi yesithando somlilo se-vacuum, i-molybdenum yokufudumala, i-furnace insulation layer, njl. Ukunkqonkqoza kunqatshelwe ngokungqongqo, kwaye isikali se-oxide sinokususwa ngononophelo. Ukuba isikali se-iron oxide kunye nezinye izinto ezingcolileyo azisuswanga ngexesha, indawo etyhidiweyo iya kuvutha kunye ne-insulation layer, ibangele ukuba ucingo lwe-molybdenum luncibilike.

5. Emva kokuba isithando somlilo sishushu, inkqubo ye-vacuum ayinakutshatyalaliswa ngokukhawuleza, makungabikho ukuvula umnyango wesithando somlilo. Qaphela ukuba igeyiji yevacuum kufuneka icinywe phambi kokuba igcwalise umoya ukuthintela ukuguga kwevacuum. Xa iqondo lobushushu lingaphezulu kwe 400℃, kufuneka lingapholiswa ngokukhawuleza. Kwi-vacuum yokufudumeza into, kulula ukubangela i-oxidation xa iqondo lokushisa liphezulu, idigri ye-vacuum ayilungile, kwaye utshintsho olubandayo kunye nobushushu lukhulu. Kwiziko lokufudumeza i-molybdenum, ngexesha lokusetyenziswa okuqhelekileyo kunye nokugcinwa, kufuneka zipholiswe ngaphantsi kwe-200 ° C ngaphambi kokuba i-nitrogen ekhuselayo imiswe. Ucango lwesithando somlilo lunokuvulwa kuphela ngaphantsi kwama-80°C.

6. Isixokelelwano sokupholisa siyinxalenye ebalulekileyo yesithando somlilo sevacuum. Isiphaluka samanzi okupholisa kufuneka sigcinwe singenasiphelo, ngaphandle koko ukushisa kwamanzi kuya kunyuka kwaye kubangele ukuba umatshini ayeke. Le yingxaki edla ngokungahoywa xa i-atmosfera isebenza. Inokubangela umonakalo omkhulu kwiziko lobushushu obuphezulu bevacuum xa ingaqwalaselwanga. Injongo yokunyanga amanzi okupholisa ngoncedo lwe-biological decomposition kunye neendlela zekhemikhali kukugcina amaminerali ekumisweni kunye nokunciphisa ukuqokelelwa kwentlenga kwi-tube yerubha, ityhubhu yenyoka kunye nejacket yamanzi, ukuze amanzi ahambe kakuhle. Oku ngokuqhelekileyo kwenziwa sisixhobo esizenzekelayo, esinokubeka iliso kwindlela amanzi ahamba ngayo, ngokuzalisa ngokuzenzekelayo ii-agent agents, ukugungxula umzila wamanzi, kunye nokongeza amanzi amatsha.
