ʻOi aku ka mālama ʻana i ka ikehu a me ke kumu kūʻai——Hoʻolauna i ka graphite silicon carbide crucible

Hoʻolauna

I ka ʻimi ʻana i ka pono o ka ikehu a me ka mālama kālā,graphite silicon carbide crucibleshe koho maikaʻi loa no nā noi ʻoihana. Me kāna mau mea kūikawā a me kāna kaʻina hana, ʻoi aku ka lōʻihi o ka lawelawe ʻana o ka crucible, ka maikaʻi o ka thermal conductivity, oxidation a me ka corrosion resistance, kiʻekiʻe kiʻekiʻe o ka nui a me ka launa ʻana i ke kaiapuni. Hāʻawi kēia ʻatikala i kahi kikoʻī kikoʻī o nā hiʻohiʻona a me nā pono o ka graphite silicon carbide crucibles, ko lākou ʻano kino a me kemika, a me nā huahana pili.

Hoʻonui i ke ola hana
He lōʻihi ke ola lawelawe ʻana o nā crucibles silicon carbide graphite. Ma muli o ka hoʻohana ʻana o ka mea kūʻai aku, nā kikoʻī hana a me ka mālama maʻamau, hiki i ke ola lawelawe ke hiki i 6 a 18 mau mahina a ʻoi aku paha. ʻAʻole mālama wale kēlā ola lōʻihi i nā ʻoihana i ke kumukūʻai o ka hoʻololi pinepine ʻana i nā crucibles, akā e hōʻemi ana hoʻi i ka downtime, no laila e hoʻomaikaʻi ai i ka hana hana.

ʻOi aku ka maikaʻi o ka thermal conductivity
Loaʻa i ka crucible ka hoʻoili wela maikaʻi loa a mālama i ka hana hoʻoili wela maikaʻi ma ka 6 a 8 mau mahina o ka hoʻohana ʻana. Eia nō naʻe, he mea nui e hoʻomaopopo e hiki ke hoʻopōkole i nā kaiapuni ʻino loa i ke ola lawelawe o ka crucible a me ka conductivity thermal. Ma o ka mālama ʻana a me ka hana ʻepekema, hiki ke hoʻonui ʻia ka hana o ka crucible, mālama ʻia ka ikehu, a hoʻomaikaʻi i ka hana hana.

Anti-oxidation a me ka anti-corrosion
Hana ʻia ʻo Graphite silicon carbide crucible me ka hoʻohana ʻana i nā mea kiʻekiʻe a me ka ʻenehana kaomi isostatic, kahi e hoʻonui nui ai i kona kūʻē ʻana i ka oxidation, thermal shock a me ka corrosion. ʻO kēia mau hiʻohiʻona e hiki ai i ka crucible ke mālama i ka hana paʻa i nā wahi wela kiʻekiʻe, e hoʻonui i kona ola lawelawe, a e hōʻemi i ka hoʻopau ʻana i ka hana a me nā mea hana i hana ʻia e ka pōʻino crucible.

Kiʻekiʻe bulk density
ʻO ka ikaika kiʻekiʻe a me ka porosity haʻahaʻa haʻahaʻa o ka graphite silicon carbide crucibles e hāʻawi i ka hoʻoili wela maikaʻi a me ke ola lawelawe lōʻihi. ʻAʻole wale ke ʻano o ka paʻa kiʻekiʻe o ka crucible, akā hoʻonui pū i ke kūʻē ʻana o ka crucible i ka hopena mechanical, e hōʻoia ana i ka hana paʻa ma lalo o nā kūlana hana kiʻekiʻe.

Ka palekana kaiapuni a me ka ikehu
He hana maikaʻi loa ʻo Graphite silicon carbide crucible i ka mālama ʻana i ka ikehu a me ka hoʻomaikaʻi maikaʻi ʻana. ʻO kāna hoʻolālā a me kāna koho waiwai e hoʻoponopono pono i nā pilikia o ka haumia haumia a me ka porosity make-casting, ʻaʻole ia e hoʻomaikaʻi wale i ka maikaʻi o ka huahana, akā e hōʻemi ana hoʻi i ka hoʻohana ʻana i ka ikehu i ka wā o ke kaʻina hana, a hoʻokō i nā koi palekana o ka ʻoihana hou.

ʻO ka nui o ke kīʻaha graphite silikon carbide
Hāʻawi mākou i nā crucibles graphite silicon carbide i nā nui like ʻole e hoʻokō i nā pono hana like ʻole. No nā nui kikoʻī a me nā ʻike huahana hou aʻe, e ʻoluʻolu e kelepona iā mākou.

ʻAno kino a me kemika
ʻAno kīʻaha: graphite silicon carbide crucible, clay crucible
ʻO ke kalapona (%): ≥38, ≥45
Ka nui o ka leo (g/cm3): ≥1.70, ≥1.85
ʻIke ʻia ka porosity (%): ≤29, ≤21
Ka ikaika compressive (Mpa): ≥20, ≥25
Degere Refractory (℃): ≥1500, ≥1500
ʻO kēia mau waiwai kino a me kemika e pili ana i nā kūlana aupuni no nā crucibles graphite, e hōʻoiaʻiʻo ana i ka hilinaʻi o ka maikaʻi o ka huahana a me ka hana.

Nā Huahana Pili
Ma kahi o ka graphite silicon carbide crucibles, hāʻawi pū mākou i nā huahana e pili ana:
- Pālolo graphite crucible
- ʻO ka pahu kalapona graphite
- Paipu pale Thermocouple
- Hoʻopau i ka rotor
- Nā mea hana hoʻokiʻekiʻe crucible
- Mea hoʻomaʻemaʻe crucible
- Ka uhi pale ahi
- Ke kumu graphite
- Papa graphite
- Ke kapuahi pahu
Hoʻopili kēia mau huahana i ka nui o nā mea e pono ai i ka ʻoihana foundry a me nā ʻoihana metallurgical, e hāʻawi ana i ke kākoʻo piha no kāu kaʻina hana.

I ka hopena
ʻAʻole pono wale ke koho ʻana i ka graphite silicon carbide crucible i ka mālama ʻana i ka ikehu a me ka mālama ʻana i ke kaiapuni, akā hoʻomaikaʻi nui hoʻi i ka hana hana a me ka maikaʻi o ka huahana. Manaʻo mākou e hana pū me ʻoe no ka hoʻokō ʻana i nā pahuhopu hoʻōla a me nā kumu kūʻai. No ka ʻike hou aku a i ʻole e kau i kahi kauoha, e ʻoluʻolu e kelepona mai iā mākou.
