ʻO kā mākouPohaku Pohakuhana ʻia mai ka isostatically kaomi silicon carbide graphite, kahi mea e hāʻawi ana i ke kūpaʻa kiʻekiʻe kiʻekiʻe a me ka conductivity thermal maikaʻi loa, e lilo ia i mea pono no nā noi hoʻoheheʻe ʻoihana.

1. Silicon Carbide (SiC): Ua ʻike ʻia ʻo Silicon carbide no kona paʻakikī loa a me ke kūʻē maikaʻi ʻana i ka ʻaʻahu a me ka ʻino. Hiki iā ia ke pale i nā hopena kemika wela kiʻekiʻe, e hāʻawi ana i ka paʻa ʻoi aku ka maikaʻi ma lalo o ke koʻikoʻi wela, e hōʻemi ana i ka pilikia o ka pohā i ka wā e hoʻololi koke ʻia ka mahana.
2. Natural Graphite: Hāʻawi ka graphite kūlohelohe i ka conductivity thermal kūikawā, e hōʻoiaʻiʻo ana i ka hāʻawi ʻana i ka wela me ka like ʻole i loko o ka crucible. ʻAʻole like me nā graphite crucibles maʻamau, hoʻohana kā mākou cylindrical crucible i ka graphite kūlohelohe kiʻekiʻe, kahi e hoʻomaikaʻi ai i ka hoʻoili wela a hoʻemi i ka hoʻohana ʻana i ka ikehu.
3. Isostatic Pressing Technology: Hoʻokumu ʻia ka crucible me ka hoʻohana ʻana i ke kaomi isostatic kiʻekiʻe, e hōʻoiaʻiʻo ana i ka paʻa like ʻole me nā hemahema o loko a i waho paha. Hoʻonui kēia ʻenehana i ka ikaika a me ka pale ʻana o ka crucible, e hoʻolōʻihi i kona kūpaʻa ma nā wahi wela kiʻekiʻe.

Hana:

1. ʻO ka Thermal Conductivity Kiʻekiʻe: Hana ʻia ka Cylindrical Crucible mai nā mea hoʻonaninani wela kiʻekiʻe e hiki ai ke hoʻohele wikiwiki a me ka wela. Hoʻonui kēia i ka maikaʻi o ke kaʻina hana hoʻoheheʻe me ka hoʻemi ʻana i ka ikehu. Hoʻohālikelike ʻia i nā crucibles maʻamau, hoʻomaikaʻi ʻia ka conductivity thermal e 15% -20%, e alakaʻi ana i ka mālama wahie nui a me ka wikiwiki o ka hana ʻana.
2. ʻOi aku ka maikaʻi o ka Corrosion Resistance: ʻO kā mākou silicon carbide graphite crucibles he kūpaʻa loa i nā hopena corrosive o nā metala hoʻoheheʻe a me nā kemika, e hōʻoiaʻiʻo ana i ka paʻa a me ka lōʻihi o ka crucible i ka wā lōʻihi. He mea maikaʻi kēia no ka hoʻoheheʻe ʻana i ka aluminika, ke keleawe, a me nā ʻāpana metala like ʻole, e hōʻemi ana i ka mālama ʻana a me ka hoʻololi pinepine ʻana.
3. ʻO ke ola lawelawe lōʻihi: Me kona ʻano kiʻekiʻe kiʻekiʻe a me ka ikaika kiʻekiʻe, ʻo ke ola o kā mākou cylindrical crucible he 2 a 5 mau manawa ʻoi aku ka lōʻihi ma mua o nā crucibles graphite pālolo kuʻuna. ʻO ke kūpaʻa kiʻekiʻe i ka haki ʻana a me ka ʻaʻahu e hoʻonui i ke ola hana, hoʻohaʻahaʻa i ka manawa hoʻomaha a me nā kumukūʻai pani.
4. Kū'ē Kū'ē Kiʻekiʻe: ʻO kahi haku mele i hoʻonohonoho pono ʻia e pale pono i ka oxidation o ka graphite, e hōʻemi i ka hōʻemi ʻana i nā wela kiʻekiʻe a hoʻolōʻihi i ke ola o ka crucible.
5. ʻO ka ikaika o ka mīkini kiʻekiʻe: Mahalo i ke kaʻina hana isostatic kaomi ʻana, ke kaena nei ka crucible i ka ikaika mechanical kūikawā, e mālama ana i kona ʻano a me ka lōʻihi i nā kaiapuni wela. He mea kūpono kēia no nā kaʻina hoʻoheheʻe e koi ana i ke kaomi kiʻekiʻe a me ke kūpaʻa mechanical.

Nā Pono Huahana:

• Pono Pono: ʻO ka hoʻohana ʻana i ka graphite maoli a me ka silicon carbide e hōʻoia i ka conductivity thermal kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion, e hāʻawi ana i ka hana mau i nā wahi paʻakikī, kiʻekiʻe-mehana.
• Hoʻolālā Kiʻekiʻe Kiʻekiʻe: Hoʻopau ka ʻenehana kaomi Isostatic i nā puka o loko a me nā māwae, e hoʻomaikaʻi nui i ka paʻa a me ka ikaika o ka crucible i ka wā hoʻohana lōʻihi.
• ʻO ke kūpaʻa kiʻekiʻe: Hiki ke kū i nā mahana a hiki i 1700 ° C, kūpono kēia crucible no nā kaʻina hana hoʻoheheʻe a me ka hoʻolei ʻana e pili ana i nā metala a me nā ala.
• ʻO ka ikaika o ka ikehu: ʻO kāna mau waiwai hoʻoili wela maikaʻi e hoʻemi i ka hoʻohana ʻana i ka wahie, ʻoiai ʻo ka mea pili i ke kaiapuni e hōʻemi i ka pollution a me ka ʻōpala.

ʻO ke koho ʻana i kā mākou Cylindrical Crucible hana kiʻekiʻe ʻaʻole ia e hoʻomaikaʻi wale i kāu hoʻoheheʻe ʻana akā e hōʻemi hoʻi i ka hoʻohana ʻana i ka ikehu, hoʻonui i ke ola o nā mea hana, a hoʻohaʻahaʻa i nā kumukūʻai mālama, i ka hoʻomaikaʻi ʻana i ka pono hana.

1. ʻO ka hoʻoili wela
   • Hōʻike nā ʻōpala graphite i ka hoʻoili wela maikaʻi loa, e hōʻoia ana i ka hāʻawi ʻana i ka wela. Hoʻemi kēia waiwai i nā wahi wela a hōʻoia i ka hoʻoheheʻe ʻana, e hana maikaʻi loa ia no nā metala e like me ke gula, ke keleawe, a me ka alumini.
   • Hiki i ka conductivity thermal ke hiki i nā waiwai a hiki i 100 W/m·K, ʻoi aku ka maikaʻi ma mua o nā mea refractory kuʻuna.
2. Kū'ē Kūlana Kiʻekiʻe
   • Hiki i nā crucibles graphite ke kū i nā wela kiʻekiʻe loa, a hiki i ka 1700 ° C i loko o nā ea inert a i ʻole nā ​​​​kūlana ʻawaʻawa. Hāʻawi kēia iā lākou e mālama i ka pono o ke kūkulu ʻana i nā kaiapuni koi ʻole me ka hoʻohaʻahaʻa ʻole.
   • Paʻa kēia mau crucibles a kūpaʻa i ka deformation ma lalo o ka wela nui.
3. Haʻahaʻa haʻahaʻa o ka hoʻonui wela
   • He haʻahaʻa haʻahaʻa nā mea graphite o ka hoʻonui wela (e like me 4.9 x 10^-6 / °C), e hōʻemi ana i ka pilikia o ka pohā a i ʻole ka haʻalulu wela ke ʻike ʻia i nā loli wikiwiki.
   • Hana kēia hiʻohiʻona i nā crucibles graphite kūpono loa no nā kaʻina hana e pili ana i ka hoʻomehana ʻana a me nā pōʻai hoʻomaha.
4. Pale ʻino
   • ʻAʻole inert kemika ka Graphite a hāʻawi i ke kūpaʻa kiʻekiʻe i ka hapa nui o nā waikawa, alkalis, a me nā mea ʻino ʻē aʻe, ʻoi aku ka hoʻohaʻahaʻa ʻana a i ʻole ka lewa. He mea kūpono kēia i nā crucibles graphite no nā kaiapuni kemika koʻikoʻi i ka hoʻolei metala a hoʻomaʻemaʻe paha.
   • Hiki ke hoʻonui hou ʻia ke kūʻē ʻana o ka mea i ka oxidation e nā uhi a i ʻole nā ​​hana kūikawā, e hōʻoia ana i ka lōʻihi o ke ola lawelawe.
5. Hoʻolima Uila
   • Ma ke ʻano he conductor maikaʻi o ka uila, kūpono nā mea graphite no nā noi hoʻomehana induction. Hiki i ka conductivity uila kiʻekiʻe ke hoʻohui maikaʻi me nā ʻōnaehana induction, e hōʻoiaʻiʻo ana i ka hoʻomehana wikiwiki a me ka like.
   • Hoʻohana pono kēia waiwai i nā kaʻina hana e koi ana i nā crucibles induction heater, hoʻonui i ka pono o ka hana i nā ʻoihana e like me ka foundry work a me ka metallurgy.
6. Maʻemaʻe a me nā mea i haku ʻia
   • ʻO nā pahu kalapona kalapona maʻemaʻe kiʻekiʻe (a hiki i ka 99.9% maʻemaʻe) he mea nui ia no nā noi kahi e pale ʻia ai ka hoʻohaumia metala, e like me ka hana ʻana i nā metala makamae a i ʻole nā ​​ceramics kiʻekiʻe.
   • Hoʻohui ʻia nā ʻāpana graphite silicon carbide i nā waiwai o ka graphite a me ka silicon carbide, e hāʻawi ana i ka ikaika mechanical i hoʻonui ʻia, ka pale ʻana o ka oxidation, a me kahi helu heheʻe kiʻekiʻe, kūpono no nā kūlana hana koʻikoʻi.
7. Ka lōʻihi a me ka lōʻihi
   • Hana ʻia nā crucibles graphite Isostatically i loaʻa i ke ʻano like ʻole a me ka ikaika, e hopena i nā ola lōʻihi a hoʻemi ʻia ka hemahema o ka waiwai i ka wā o nā hana wela. ʻOi aku ka paʻa o kēia mau crucibles i ka erosion a me ka pōʻino mechanical.

8. Huina Kemika:

   • Kalapona (C): 20-30%
   • Silicon Carbide (SiC): 50-60%
   • Alumina (Al2O3): 3-5%
   • Nā mea ʻē aʻe: 3-5%
9. Nā Nui a me nā ʻano hoʻohālikelike
   • Loaʻa kā mākou graphite crucibles i nā ʻano nui a me nā hoʻonohonoho. Mai nā kīʻaha graphite liʻiliʻi (kūpono no ka hoʻāʻo ʻana i ka metala nui o ka lab-scale) a hiki i nā crucibles nui i hoʻolālā ʻia no ka hoʻoheheʻe ʻana i ka ʻoihana, hāʻawi mākou i nā hopena kūpono no kēlā me kēia noi.
   • Hiki ke hoʻopilikino ʻia nā crucibles graphite-lined me nā spouts i nā koi hoʻoheheʻe kikoʻī, e hōʻoiaʻiʻo ana i ka maʻalahi a me ka pono i ka lawelawe ʻana metala.
