ʻO Silicon Carbide Graphite Crucible

Nā hiʻohiʻona

ʻO kā mākouʻO Silicon Carbide Graphite Cruciblehōʻike i kahi holomua i ka ʻenehana crucible, i hoʻolālā ʻia e hoʻokō i nā koi koi o nā noi hoʻolei metala kiʻekiʻe. ʻO ka hoʻohui ʻana i nā waiwai kūʻokoʻa o ka graphite flake maoli me nā ʻāpana silicon carbide (SiC), hāʻawi kā mākou crucibles i ka conductivity thermal like ʻole, ka pale oxidation, a me ka lōʻihi mechanical.

Nā mea nui:

  1. Hoʻonui i ka hoʻokō wela: ʻO ka hoʻohui ʻana o ka silicon carbide e hoʻomaikaʻi i ka hana hoʻoili wela o ka crucible, e hōʻemi ana i ka manawa e pono ai e hoʻoheheʻe i nā metala a me ka hoʻomaikaʻi nui ʻana i ka ikehu. Hiki i kā mākou crucibles ke mālama i ka 2/5 a i ka 1/3 ʻoi aku ka ikaika ma mua o ka graphite crucibles kuʻuna.
  2. ʻO ke kū ʻana i ka haʻalulu wela: ʻO ka haku mele ʻana o kā mākou crucible hiki iā ia ke hoʻomanawanui i ka hoʻololi ʻana o ka mahana me ka ʻole o ka haki ʻana, e hiki ai ke kūpaʻa i ka haʻalulu wela. ʻO ka wela a i ʻole ka maʻalili, mālama ka crucible i kona kūpaʻa.
  3. Kū'ē wela kiʻekiʻe: Ko makouʻO Silicon Carbide Graphite Crucibleshiki ke pale i nā mahana wela mai ka 1200 ° C a hiki i 1650 ° C, e kūpono iā lākou no ka hoʻoheheʻe ʻana i nā ʻano metala non-ferrous like ʻole, me ke keleawe, aluminika, a me nā metala makamae.
  4. ʻOi aku ka maikaʻi o ka Oxidation a me ka Corrosion Resistance: No ka pale ʻana i ka hoʻohāhā ʻana i nā wela kiʻekiʻe, hoʻopili mākou i ka uhi ʻana o nā aniani multi-layer i kā mākou crucibles, e hāʻawi ana i ka pale hou mai ka oxidation a me ka corrosion. Hoʻonui kēia i ke ola o ka crucible, ʻoiai ma nā wahi paʻakikī.
  5. Ili pipili ole: ʻO ka ʻili maʻemaʻe a hoʻopili ʻole o ka graphite e hōʻemi i ke komo ʻana a me ka hoʻopili ʻana o nā metala i hoʻoheheʻe ʻia, e pale ana i ka hoʻohaumia ʻana a me ka maʻalahi o ka hoʻomaʻemaʻe ma hope o ka hoʻohana ʻana. Hoʻemi pū ia i ka poho metala i ka wā o ka hoʻolei ʻana.
  6. Hoʻohaumia metala liʻiliʻi: Me ka maʻemaʻe kiʻekiʻe a me ka porosity haʻahaʻa, loaʻa i kā mākou crucibles nā mea haumia liʻiliʻi i hiki ke hoʻohaumia i ka mea hoʻoheheʻe. He mea kūpono kēia no nā noi e koi ana i nā pae kiʻekiʻe o ka maʻemaʻe i ka hana metala.
  7. Kū'ē Pilikino Mechanical: ʻO ke ʻano hoʻoikaika paʻa o kā mākou crucibles e hoʻokūpaʻa loa iā lākou i nā hopena mechanical, e like me nā mea i loaʻa i ka wā o ka ninini ʻana i nā metala hoʻoheheʻe ʻia, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka lōʻihi.
  8. Kū'ē i ka Flux a me ka Slag: Hōʻike kā mākou crucibles i ke kūpaʻa maikaʻi loa i ka flux a me ka slag, e hōʻoia ana i ka hilinaʻi lōʻihi i nā wahi e hoʻohana pinepine ʻia ai kēia mau mea.

Nā Pono Huahana:

  • Hoʻonui i ke ola lawelawe: Ke ola o ko kakouʻO Silicon Carbide Graphite CruciblesʻO 5 a 10 mau manawa ka lōʻihi ma mua o ka graphite crucibles maʻamau. Me ka hoʻohana kūpono, hāʻawi mākou i kahi palapala hōʻoia 6 mau mahina, e hōʻoiaʻiʻo ana i ka hana pono i ka manawa.
  • Maʻiʻo Silicon Carbide maʻamau: Hāʻawi mākou i nā crucibles me nā ʻano like ʻole o ka silicon carbide, i hana ʻia e hoʻokō i kāu mau koi hoʻolei kikoʻī. Inā makemake ʻoe i 24% a i ʻole 50% silicon carbide content, hiki iā mākou ke hana i kā mākou crucibles e kūpono i kāu pono hana.
  • Hoʻomaikaʻi i ka ʻoihana hana: Me nā manawa hoʻoheheʻe wikiwiki a me ka hoʻemi ʻana i ka ikehu, hoʻemi kā mākou crucibles i ka manawa haʻahaʻa a me nā koina hana, e hoʻonui i ka huahana o kāu foundry.

Nā kikoʻī:

  • Kūleʻa wela: ≥ 1630°C (hiki i nā hiʻohiʻona kikoʻī ke kū i ka ≥ 1635°C)
  • Kaona: ≥ 38% (nā hiʻohiʻona kikoʻī ≥ 41.46%)
  • ʻIke ʻia ka Porosity: ≤ 35% (nā hiʻohiʻona kikoʻī ≤ 32%)
  • ʻAiʻi Nui: ≥ 1.6g/cm³ (nā hiʻohiʻona kikoʻī ≥ 1.71g/cm³)

ʻO kā mākouʻO Silicon Carbide Graphite Crucibleshāʻawi i ka hana ʻoi aku ka maikaʻi ma nā wahi ʻoi aku ka paʻakikī, e hoʻolilo iā lākou i koho maikaʻi loa no nā noi hoʻolei metala non-ferrous. Me ka lōʻihi alakaʻi o ka ʻoihana, ke kū ʻana o ka wela, a me nā koho maʻamau, ua hana ʻia kā mākou crucibles e hāʻawi i ka pono, hilinaʻi, a me ka lōʻihi no kāu hana hoʻolei ʻana.
