Okonga amandla okwengeziwe nokonga izindleko——Isingeniso se-graphite silicon carbide crucible

Ngenisa

Ekuphishekeleni ukusebenza kahle kwamandla nokonga izindleko,graphite silicon carbide crucibleskukhona ukukhetha okuhle kakhulu kwezicelo zezimboni. Ngezinto zayo ezikhethekile kanye nenqubo yokukhiqiza, i-crucible inempilo ende yesevisi, ukuhamba kahle kwe-thermal, ukumelana ne-oxidation nokugqwala, ukuminyana kwevolumu ephezulu kanye nobungane bemvelo. Lesi sihloko sinikeza ukubuka okuningiliziwe kwezici kanye nezinzuzo ze-graphite silicon carbide crucibles, izakhiwo zabo zomzimba namakhemikhali, kanye nemikhiqizo ehlobene.

Impilo yokusebenza enwetshiwe
I-graphite silicon carbide crucibles inempilo ende yesevisi. Ngokuya ngendawo yokusetshenziswa kwekhasimende, ukucaciswa kokusebenza nokugcinwa okuvamile, impilo yesevisi ingafinyelela ezinyangeni eziyisi-6 kuye kweziyi-18 noma ngaphezulu. Impilo ende enjalo ayigcini nje ngokusindisa amabhizinisi izindleko zokushintshwa njalo kwama-crucibles, kodwa futhi kunciphisa isikhathi sokuphumula, ngaleyo ndlela kuthuthukisa ukusebenza kahle kokukhiqiza.

I-conductivity enhle kakhulu ye-thermal
I-crucible ine-thermal conductivity enhle kakhulu futhi igcina ukusebenza okuhle kokudlulisa ukushisa phakathi nezinyanga zokuqala ezi-6 kuya kweziyi-8 zokusetshenziswa. Kodwa-ke, kubalulekile ukuqaphela ukuthi izindawo ezibola kakhulu zingafinyeza impilo yesevisi ye-crucible kanye nokusebenza kwe-thermal. Ngokulungiswa nokusebenza kwesayensi, ukusebenza kwe-crucible kungakhuliswa, kugcinwe amandla, kanye nokusebenza kahle kokukhiqiza kuthuthukiswe.

I-Anti-oxidation kanye ne-anti-corrosion
I-graphite silicon carbide crucible ikhiqizwa kusetshenziswa izinto ezithuthukile kanye nobuchwepheshe bokucindezela be-isostatic, okuthuthukisa kakhulu ukumelana kwayo ne-oxidation, ukushaqeka okushisayo nokugqwala. Lezi zici zivumela i-crucible ukuthi igcine ukusebenza okuzinzile ezindaweni ezisezingeni eliphezulu, inwebe impilo yayo yesevisi, futhi inciphise ukuphazamiseka kokukhiqiza nokuguga kwemishini okubangelwa umonakalo omkhulu.

Ukuminyana kwenqwaba ephezulu
Amandla aphezulu kanye ne-porosity ephansi ebonakalayo ye-graphite silicon carbide crucibles inikeza ukudluliswa kokushisa okungcono nempilo yesevisi ende. Ukuminyana kwevolumu ephezulu akusho nje kuphela ukuqina kwe-crucible, kodwa futhi kuthuthukisa ukumelana kwe-crucible kumthelela wemishini, iqinisekisa ukusebenza okuzinzile ngaphansi kwezimo zokukhiqiza eziphezulu.

Ukuvikelwa kwemvelo nokusebenza kahle kwamandla
I-graphite silicon carbide crucible inokusebenza okuhle kakhulu ekongeni amandla kanye nokwenza ngcono ukusebenza kahle. Ukuklama kwayo nokukhethwa kwezinto ezibonakalayo kuzixazulula ngokuphumelelayo izinkinga zokungcoliswa kokungcola kanye ne-die-casting porosity, engathuthukisi nje kuphela ikhwalithi yomkhiqizo, kodwa futhi kunciphisa ukusetshenziswa kwamandla ngesikhathi senqubo yokukhiqiza, futhi ihlangabezana nezidingo zokuvikela imvelo embonini yesimanje.

I-graphite silicon carbide usayizi we-crucible
Sihlinzeka nge-graphite silicon carbide crucibles ngobukhulu obuhlukahlukene ukuhlangabezana nezidingo ezahlukene zokukhiqiza. Ukuze uthole osayizi abathile nolwazi oluthe xaxa lomkhiqizo, sicela ukhululeke ukuxhumana nathi.

Izakhiwo zomzimba namakhemikhali
Uhlobo lwe-crucible: i-graphite silicon carbide crucible, i-clay crucible
Okuqukethwe kwekhabhoni (%): ≥38, ≥45
Ukuminyana kwevolumu (g/cm3): ≥1.70, ≥1.85
I-porosity ebonakalayo (%): ≤29, ≤21
Amandla acindezelayo (Mpa): ≥20, ≥25
Iziqu ze-Refractory (℃): ≥1500, ≥1500
Lezi zakhiwo ezibonakalayo namakhemikhali zibhekisela kumazinga kazwelonke we-graphite crucibles, ukuqinisekisa ukwethembeka kwekhwalithi nokusebenza komkhiqizo.

Imikhiqizo Ehlobene
Ngokungeziwe kuma-graphite silicon carbide crucibles, siphinde sinikeze imikhiqizo ehlobene elandelayo:
- I-clay graphite crucible
- I-Carbon graphite crucible
- Ithubhu yokuvikela i-Thermocouple
- Degassing rotor
- Amathuluzi okuphakamisa ama-crucible
- Ithuluzi lokuhlanza le-crucible
- Ikhava engashi
- Isisekelo se-graphite
- Ipuleti le-graphite
- Isithando somlilo esivuthayo
Le mikhiqizo ihlanganisa izidingo eziningi ezimbonini ze-Foundry kanye ne-metallurgical, ihlinzeka ngokusekela okuphelele kwezinqubo zakho zokukhiqiza.

Ekuphetheni
Ukukhetha i-graphite silicon carbide crucible akuzuzisi nje kuphela ukongiwa kwamandla nokuvikelwa kwemvelo, kodwa futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Sibheke ngabomvu ukusebenzisana nawe ukuze sifinyelele izinjongo ezengeziwe zokonga ugesi nezokonga. Ukuze uthole ulwazi olwengeziwe noma ukufaka i-oda, sicela ukhululeke ukusithinta.
