Ukukhiqizwa kwe-graphite ekhanyayo sekuvele kakhulu ngokuqala kwezobuchwepheshe bokucindezela oku-isostatic, kumake njengendlela esezingeni eliphezulu kakhulu emhlabeni jikelele. Uma uqhathanisa izindlela zokuhlangana zendabuko, imiphumela yokucindezela e-Isstatic ku-Crucibles enokuthungwa okuyunifomu, ubukhulu obuphakeme, ukusebenza kahle kwamandla, kanye nokumelana namandla ku-oxidation. Ukusetshenziswa kwengcindezi ephezulu ngesikhathi sokubumba kuthuthukisa kakhulu ukuthungwa okuthe xaxa, ukunciphisa i-poorrity kanye nokuqinisekiswa kokuqina, njengoba kuboniswe imvelo enobuntu, wukuqinisekisa ukuvumelana kwezinto okusebenzayo kulo lonke. Le ndlela, njengoba kuboniswe kuMdwebo 2, kuphuma i-Ofderformfs inqubo yokuhlalisana kwendabuko, okuholela ekuthuthukisweni okukhulu ekusebenzeni okusebenzayo.
1. Isitatimende senkinga
Ukukhathazeka kuvela kumongo we-aluminium alloy insulance ukumelana ne-wire rucible race usebenzisa ama-graphite ama-graphite ahlelwe, nesikhathi sokuphila cishe izinsuku ezingama-45. Ngemuva kwezinsuku ezingama-20 kuphela zokusebenzisa, ukwehla okubonakalayo kokuphakelayo okushisayo kuyabonakala, kuhambisana nemifantu emincane engaphezulu kwe-Crucible's Outer Super. Ezigabeni zakamuva zokusebenzisa, ukwehla okunzima ekuphathweni okushisayo kuyabonakala, ukunikela okubaleka cishe akukuqhubeki. Ngokwengeziwe, ukuqhekeka okungaphezulu kwemibuso, futhi ukugqashuka kwenzeka phezulu kwe-Crucible's Port ngenxa ye-oxidation.
Lapho ehlola isithando somlilo esibilekile, njengoba kukhonjisiwe kuMdwebo 3, isisekelo esakhiwa izitini ezigcwele izitini sisetshenziswa, ngento yokushisa kwe-bottommost ye-wire yokumelana nendawo ephakathi nendawo. I-Phezulu eBrucible ivalwe kusetshenziswa izingubo zokulala ze-asbestos, zibekwe cishe ngo-50 mm ukusuka emaphethelweni angaphandle, kuveze i-abrasion ebalulekile emaphethelweni angaphakathi.
2. Ukuthuthuka okusha kwezobuchwepheshe
Ukwenza ngcono 1: Ukutholwa kwegrafu ecindezelwe ecindezelwe e-Isstatic
Ukusetshenziswa kwaleli nto ebekwe ngcono kakhulu kuthuthukisa uhlelo lwayo ku-Aluminium Alloy insulation fouration, ikakhulukazi ngokuya ngokumelana ne-oxidation. Ama-graphite ama-onfidize ajwayele amazinga okushisa angenhla kwamazinga okushisa angenhla kwama-400 ℃, ngenkathi izinga lokushisa lokufaka ama-aluminium alloy lisukela ngo-650 no-700 ℃. I-Clacibles ene-oxidation-engavikeli i-oxidation-engavikeli i-axidation-state ngejubane ngempumelelo inqubo ye-oxidation emazingeni okushisa angaphezu kwama-600 ℃, uqinisekise ukuthuthuka okuhle kakhulu okushisayo. Ngasikhathi sinye, kuvimbela ukuncishiswa kwamandla ngenxa ye-oxidation, ukunweba isikhathi sokuphila esisekuqaleni.
Ukwenza ngcono 2: Isisekelo Sothando Sisebenzisa i-Graphite Yezinto Ezifanayo Njenge-Elensible
Njengoba kuboniswe kuMdwebo 4, kusetshenziswa isisekelo segrafu yento efanayo neyokucacisa kuqinisekisa ukufudumala okufanayo kokungaphansi kwesembatho ngesikhathi senqubo yokushisa. Le mitinates gradients yokushisa ebangelwa ukufudumeza okungalingani futhi inciphise ukuthambekela kokuqhekeka okuvela ekushiseni okuphansi okungaphansi. Isizinda se-graphite esizinikezele sibuye siqinisekise ukusekelwa ezinzile kwe-ebethelwe, ukuhambisana nokungaphansi kwayo nokunciphisa ukuqhekeka okubangelwa ukucindezela.
Ukuthuthuka 3: Ukuthuthukiswa Kwezinkampani Zasendaweni (Umdwebo 4)
- Unqenqema lwangaphakathi oluthuthukisiwe lwesembozo somlilo, ukuvikela ukugqoka ngokuphumelelayo kokukhanya okuthe xaxa nokuqinisa ukubopha ukubopha ukubekwa uphawu kwesithando.
- Ukuqinisekisa ukuthi i-wire yokumelana inezinga eliphansi, liqinisekisa ukufudumeza okwanele.
- Ukunciphisa umthelela we-Top Fiber Blatet Seals ekufuneni okunembatho, uqinisekise ukufudumala okwanele ngaphezulu futhi kunciphisa imiphumela ye-oxidation encane yokushisa.
Ukuthuthuka 4: Ukuhlaziya izinqubo zokusetshenziswa ezinokwethenjelwa
Ngaphambi kokusetshenziswa, Preheat the ebethelwe esithandweni somlilo emazingeni okushisa angaphansi kwama-200 ℃ kumahora angama-1-2 ukuqeda umswakama. Ngemuva kokuthola kuqala, phakamisa ngokushesha izinga lokushisa libe ngu-850-900 ℃, linciphise isikhathi sokuhlala phakathi kuka-300-600 ℃ ukunciphisa i-oxidation ngaphakathi kwalolu banga lokushisa. Kamuva, yehlisa izinga lokushisa kumazinga okusebenza asebenze futhi wethule izinto eziwuketshezi ze-aluminium zokusebenza okujwayelekile.
Ngenxa yemiphumela elonakalisayo yama-ejenti acwengezayo ku-tucibles, landela amaphrothokholi wokusebenzisa afanele. Ukususwa kwe-SLAG ejwayelekile kubalulekile futhi kufanele kwenziwe lapho kushisa, njengoba ukuhlanza i-slag kuba yinselele ngenye indlela. Ukuqashelwa okuphaphama kokusebenza kwe-thermal e-Crucible's kanye nokuba khona kokuguga ezindongeni ezisebenzayo kubalulekile ezigabeni zakamuva zokusebenzisa. Ukushintshwa okufika ngesikhathi kufanele kwenziwe ukugwema ukulahleka kwamandla okungadingekile kanye nokuvuza kwe-aluminium.
3. Imiphumela Yokuthuthuka
Impilo ekhulisiwe ye-Earcialible ethuthukile iyaphawuleka, igcina ukuthuthuka okushisayo kwezikhathi ezinde, ngaphandle kokuqhekeka komhlaba. Impendulo yomsebenzisi ikhombisa ukusebenza okuthuthukile, hhayi ukunciphisa izindleko zokukhiqiza kepha futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza.
4. Isiphetho
- I-Isstatic acindezelwe graphite brucibles crucibles acperform rucibles izimfanelo zendabuko ngokuya ngokusebenza.
- Isakhiwo sesakhiwo somlilo kufanele sihambisane nosayizi nokwakheka kwecala lokusebenza kahle.
- Ukusetshenziswa okufanelekile okungekho emthethweni kwandisa kakhulu isikhathi sayo sokuphila, okulawulwa ngempumelelo izindleko zokukhiqiza.
Ngokucwaninga ngokucophelela nokwenza kahle kobuchwepheshe beFucible Funeraction, ukusebenza okuthuthukisiwe kanye nokuphila okuvuselelayo kufaka isandla kakhulu ukukhulisa ukusebenza kahle kokukhiqiza kanye nokonga izindleko.
