Nā huahana
Kīkini no ka hoolei metala
Nā hiʻohiʻona
Pāʻani koʻikoʻi nā Crucibles mahoolei metala, hōʻoia i nā kaʻina hoʻoheheʻe maʻemaʻe a maikaʻi. Hāʻawi mākounā kīʻaha no ka hoʻolei ʻana metalahoʻohana ʻiaʻenehana kaomi isostatice hoʻokō i nā koi kiʻekiʻe o nā ʻoihana ʻoihana. ʻO ke kaomi Isostatic e hiki ai ke hana i nā crucibles me ka paʻa like ʻole a me ka paʻa ʻana o ke kūkulu ʻana, e hoʻolilo iā lākou i mea kūpono no nā noi hoʻoheheʻe kiʻekiʻe a me ke kaumaha.

Nā Kūlana Kūlana a me ka Hana Hana Hana
No ka hōʻike hou aku i ka hana kiʻekiʻe o kā mākou crucibles, ua hana mākou i ka hoʻāʻo piha ʻana i nā ʻāpana koʻikoʻi:
| Palena maʻamau | ʻIkepili hoʻāʻo |
|---|---|
| ʻO ka pale wela ≥ 1630 ℃ | ʻO ka pale wela ≥ 1635 ℃ |
| ʻO ka maʻiʻo kalapona ≥ 38% | ʻO ka maʻiʻo kalapona ≥ 41.46% |
| ʻIke ʻia ka porosity ≤ 35% | ʻIke ʻia ka porosity ≤ 32% |
| Ka nui o ka leo ≥ 1.6g/cm³ | ≥ 1.71g/cm³ |
Hōʻike kēia mau hopena i ka maikaʻi koʻikoʻi o kā mākou crucibles, ʻaʻole i hui wale akā ma mua o nā ʻāpana maʻamau i manaʻo ʻia i ka ʻoihana hoʻolei. ʻO ka pale wela kiʻekiʻe a me ka maʻi kalapona e hāʻawi i ka hana ʻoi aku ka maikaʻi ma nā noi wela kiʻekiʻe, ʻoiai ʻo ka porosity ʻike haʻahaʻa e hōʻoia i ka ikaika mechanical kiʻekiʻe.
Ke koho ʻana i ka ipu hao kūpono no kāu kaʻina hoʻolei metala
Hāʻawi ʻia kā mākou crucibles i ʻelua ʻano kumu:graphite pālolo cruciblesakiʻi kiʻi kiʻi kiʻi kiʻi. Eia pehea e koho ai i ka ipu hao kūpono no kāu kaʻina hoʻoheheʻe metala:
- Nā Kuʻi Palolo Graphite: He kūpono no nā haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa e like me ka hoʻolei ʻana i ke keleawe a i ʻole nā metala makamae. Hāʻawi kēia mau crucibles i ka mālama wela maikaʻi loa a he kumukūʻai.
- ʻO Silicon Carbide Graphite Crucibles: ʻOi aku ka maikaʻi no ka hoʻolei ʻana i ka wela, ʻoi aku ka maikaʻi no nā metala non-ferrous e like me ka alumini. Me ka hoʻololi ʻana i ka wela wikiwiki, hāʻawi kēia mau crucibles i hoʻonui i ka pale ʻana i ka haʻalulu wela a me ke kūpaʻa corrosion, e hoʻolilo iā lākou i mea kūpono no nā noi koi ʻoi aku.
ʻO nā kīʻaha no ka hoʻolei metala
Me ka oi15 makahiki o ka ʻikei ka ʻoihana hana crucible, ʻike ʻia kā mākou hui no ka hana ʻana i ke ʻano kiʻekiʻepahu hoolei metalame ka hoʻohana ʻana i nā kaʻina hana hou. Hoʻolaha mākou i nā mea ʻeluagraphite pālolo cruciblesakiʻi kiʻi kiʻi kiʻi kiʻi, mālama i nā pono ʻoihana like ʻole ma ka honua holoʻokoʻa.
ʻO kā mākouʻenehana kaomi isostatichōʻoia i ka pae kiʻekiʻe o ka maikaʻi, e hāʻawi ana i nā crucibles ʻaʻole lōʻihi wale nō akā ke kumu kūʻai hoʻokūkū. Hāʻawi haʻaheo mākou i kā mākou huahana i nā ʻāina e like meWiekanama, Tailani, Malaia, ʻInidonesia, aPakitana, kahi i ʻike ʻia ai kā mākou crucibles no kā lākou hana ʻoi aku ka maikaʻi e hoʻohālikelike ʻia me nā hōʻailona honua.
Ke koho ʻana i ka ponoipu hao no ka hoolei metalaHe mea koʻikoʻi ia i ka hōʻoia ʻana i ka maikaʻi a me ka huahana i kāu mau hana hoʻokumu. Menā kīʻaha isostatic kaomi, loaʻa iā ʻoe ke kūpaʻa kiʻekiʻe, ke kūpaʻa wela, a me ka maikaʻi o ke kumukūʻai. ʻO kā mākou ʻike nui a me ka hoʻokō ʻana i ka maikaʻi e hoʻolilo iā mākou i mea hoʻolako hilinaʻi no nā foundries a puni ka honua.
E kelepona mai iā mākou i kēia lāe aʻo hou e pili ana i kā mākoupahu hoolei metalahiki ke hoʻonui i kāu hana hana. E kōkua mākou iā ʻoe e ʻimi i ka hopena crucible kūpono i kūpono i kāu mau pono kikoʻī.
