Igayidi ephelele yama-graphite ama-brucIbles kanye nemikhawulo yokushisa

1. Isingeniso ku-graphite crucibles

Ama-graphite ama-brucIblesamathuluzi abalulekile embonini yensimbi yokusakaza. Kepha yini ebenza babaluleke kakhulu, futhi kungani amathoyizi ochwepheshe ancike kuma-graphite kwezinye izinto zokwakha? Konke kwehlela ezakhiweni eziyingqayizivele zegraphite: Ukuvuselelwa okuphezulu okushisayo, ukumelana nokushisa okuhlukile, kanye nokuqina kwamakhemikhali okumangalisayo.

Kusetshenziswe kabanzi ezimbonini ezinjengokuphonsa insimbi, ukucwengwa kwensimbi okuyigugu, kanye namathole, ama-graphite ama-trucibles athenjwa ngokuphatha amazinga okushisa aphezulu kanye nezinsimbi ezahlukahlukene. Ziyinto evame kakhulu ezinqubweni ezibandakanya amathoyizi we-aluminium e-propane noma izimfanelo zokungeniswa okushisa kakhulu. Ama-graphite ama-brucIbles awagcini ngokumelana nezimo ezimbi kakhulu kepha futhi aqinisekise ukungcoliswa okuncane, okubaluleke kakhulu ekuhlanzeni kwensimbi.

2. Ukuqonda ukuqonda okuncibilikayo kwe-graphite yokunciphisa kanye nemikhawulo yokushisa

2.1. Ukuncibilika kokushisa kwe-graphite

I-Graphite inendawo ephezulu kakhulu yokuncibilika - cishe u-3,600 ° C (6,512 ° F). Lokhu kushisa kungaphezu kwamaphoyinti ancibilikayo asetshenziswa kakhulu kumathoni atholwayo, anjengokuthi:

• Ithusi: 1,085 ° C (1,984 ° F)
• Aluminiyamu: 660 ° C (1,220 ° F)
• Insimbi yoku-ayina: 1,538 ° C (2,800 ° F)

Ngenxa yalokhu, i-graphite ilungele izinhlelo zokusebenza lapho kudingeka khona ukuqina kokushisa okukhulu. Ngenkathi i-graphite ingavamisi iphuzu layo lokuncibilika ezilungiselelweni zezimboni, izinga lokushisa layo eliphakeme eliphakeme liqinisekisa ukuqina nokuqina ngesikhathi sokuchayeka isikhathi eside ekushiseni okwedlulele.

2.2. I-graphite lokushisa elinokushisa bubanzi

Ama-graphite amaningi ama-grapte alinganiselwe ukubekezelela amazinga okushisa aphakathi kuka-1,800 ° C kuya ku-2,800 ° C kuya ngokwakheka kwawo kanye nenqubo ethile yokukhiqiza. Lokhu kumelana okushisa okuphezulu kwenza ama-graphite ama-rucicibles alungele izinhlelo ezahlukahlukene zezicelo, kusuka ekunciphiseni izinsimbi zensimbi njengethusi ne-aluminium ekusingatheni ama-alloys ngisho nezinsimbi ezinhle.

Insimbi yanama ini	Iphoyinti Lokuncibilika (° C)	Kunconywe impahla ebekiwe
Ithusi	1,085	I-Graphite, i-Silicon Carbide
Aluminiyamu	I-660	I-Graphite, ubumba
Isiliva	961	I-graphite
Imali ebomvu	1,064	I-graphite
Insimbi	1,370 - 1,520	I-Graphite, i-Silicon Carbide

Qaphela: Le thebula liqokomisa ukuthi ama-grapIte ama-brucibles anikeza kanjani ukuguquguquka okudingekayo kwezinsimbi ezahlukahlukene.

3. I-Graphite Crucibles vs ezinye izinto ezisebenzayo

Akuwona wonke ama-crucible adalwe alingana. Nakhu ukuthi i-Graphip iqhathanisa kanjani nezinye izinto ezithandwayo:

• I-Refractory Cement Cument: Yaziwa ngokuqina kwayo nokusebenza kwezindleko, i-Refractionalt Refractional Centmer Imfanelo isebenza kahle kuzinhlelo zokusebenza ezinamazinga okushisa aphakathi. Kodwa-ke, abaswele umthamo wokushisa okuphezulu kanye nokuphikiswa okushisayo okushisayo kwe-graphite.
• I-Silica ne-Ceramic Curicibles: Lezi zivame ukusetshenziselwa ama-alloys athile noma izilungiselelo zelabhoratri kodwa zivame ukungakwazi ukuqina kwezicelo eziphakeme zezimboni. Baphinde bathambekele ekushashweni okushisayo, ikakhulukazi ngaphansi kokushisa okusheshayo nemijikelezo yokupholisa.

Impahla ephalekile	Ukushisa kwe-MAX (° C)	Izicelo ezinhle kakhulu
I-graphite	1,800 - 2,800	Ukuphonswa kwensimbi okushisa kakhulu, ukucwilisa
I-Silicon Carbide	I-1,650 - 2,200	Izinsimbi eziyisisekelo, ama-alloys
I-refractory cement	1,300 - 1,800	Ukusebenza okuzenzakalelayo kokushisa okusebenzayo
Isihlaloni	1,600 - 1,800	Izicelo zelebhu kanye namakhemikhali

3.1. Kungani Khetha i-Graphite?

Ama-graphite exlels lapho ezinye izinto zisebenza khona. Ukumelana kwayo kokugqwala kwamakhemikhali, ukwanda okushisayo okuphansi, kanye nekhono lokumelana nokushaqeka kwe-thermal kwenze kube ukukhetha okuphakeme kwezimboni zensimbi. I-graphite kan-real-recervity enezinkimbinkimbi futhi ivimbela ukungcoliswa, iqinisekisa imikhiqizo esezingeni eliphakeme.

I-4. Ukukhetha ilungelo elifanelekile lokuphonsa insimbi

Ukukhetha ukucacisa okuyilo kubandakanya okungaphezu kokukwazi nje izidingo zokushisa. Nazi ezinye izinto okufanele zicatshangelwe:

• Usayizi osebenzayo: Ama-graphite ama-crucibles eza ngosayizi ahlukahlukene, kusukela kuma-eartible ama-lageratory ama-rucibles kuya kumamodeli wezimboni ezikwazi ukubamba amakhulu amakhilogremu wensimbi. Usayizi osebenzayo kufanele ukhethwe ngokususelwa kwivolumu yensimbi ecutshungulwe kanye nohlobo lomlilo.
• Uhlobo: Ama-rucibles ayatholakala ngezimo eziningi, njengezindlela zokugibela, ezi-conical, kanye nezingaphansi. I-Shape Ithosha ukusebenza kahle kokuthululwa, ukusatshalaliswa okushisayo, nokuphathwa kalula.
• Ububanzi bokushisa: Qinisekisa njalo ukubekezelela kwezinga lokushisa kwento ebekiwe, ikakhulukazi uma usebenza ngezinsimbi ezidinga ukushisa okushisa okuphezulu, njengensimbi nethusi.

Uhlobo olusebenzayo	Okungcono kakhulu	Izinzuzo
Cylindrical	Ukuphonsa okujwayelekile	Ngisho nokusatshalaliswa kokushisa, okuguquguqukayo
-Nengqondo	Ukululeka okuthululwa	Ukuthulula okulula, kunciphisa ukuchitheka
Phansi-uthele	Izicelo ezinkulu ze-wavery	Ukuhamba ngempumelelo okusebenzayo, kunciphisa ukungcoliswa

Ukukhetha okuthembekileI-graphite ecashileUmkhiqizi ubalulekile ekusebenzeni kahle kokusebenza kanye nokuphila isikhathi eside kwemishini yakho. Nazi ezinye zezinto ezibalulekile okufanele uzibheke kumenzi:

• Ikhwalithi ebonakalayo: I-graphite ephezulu yokuhlanza iqinisekisa ukumelana okushisa kangcono, inciphisa ukugqoka, futhi yehlise ukungcola.
• Inqubo Yokukhiqiza: Amasu afana nomphumela wokucindezela ama-Isstatic kuma-denser ama-crucibles amelana nezinguquko zokushisa kangcono.
• Izinketho Zokwezifiso: Abanye abakhiqizi banikela ngamasayizi ngokwezifiso nobukhulu bokufanisa izidingo ezithile zezimboni.

Ukusebenza nomenzi onolwazi akuqinisekisi kuphela ikhwalithi kodwa futhi kunikeza ukufinyelela kwesiqondiso sesazi ekukhetheni okubekwe kwesokudla kwezicelo ezithile.

I-6. Ukunakekelwa kanye nokunakekelwa kwama-graphite amabala

Ukunakekelwa okufanele kunweba isikhathi sokuphila se-graphite ama-graples futhi kuqinisekisa ukusebenza okungaguquki. Nawa amanye amathiphu wesondlo:

• Ukucasha: Njalo Preheat i-graphible ecashile ngaphambi kokusetshenziswa kwayo kokuqala ukushayela noma yimuphi umswakama oseleyo futhi uvikele ukuqhekeka.
• Gwema izinguquko zokushisa okusheshayo: I-Graphite imelana nokushaqeka kwe-thermal, kepha amashifu okushisa angazelelwe asakwazi ukudala umonakalo.
• Hlanza njalo: Izinsalela zensimbi zingasabela nge-graphite, zilimaza ngokusobala. Ukuhlanza ngemuva kokusetshenziswa ngakunye kuvimbela ukwakheka.
• Ukubeka: Gcina ama-graphite amabhulukwe endaweni eyomile ukuvikela ukumunca umswakama, okungaholela ekushashweni okushisayo ekuvuseleleni kabusha.

Ukulandela lezi zinyathelo kusiza ukugcina ubuqotho bezinhlekelele kanye nokusebenza okushisayo kwama-graphite ama-gruples, kunciphisa isidingo sokufakwa kabusha kwezidingo.
