Hana ʻia kā mākou mau kīʻaha nui maiʻO ka carbide silikona kūlana kiʻekiʻe (SiC)agraphitecomposites, e hāʻawi ana i ka maikaʻi o ka wela, ka ikaika mechanical, a me ke kū'ē i ka haʻalulu wela. Ua koho ʻia kēia mau mea no ko lākou hiki ke mālama i ka wela wela a me nā wahi corrosive, e hana ana i nā crucibles kūpono no ka hoʻoheheʻe ʻana i nā metala e like me:
ʻO kēlā me kēia crucible nui ka pololei-hana ʻia ma okaomi isostatice hōʻoia i ka mānoanoa like ʻole a me ka paʻa, e hopena i ka hāʻawi ʻana i ka wela maikaʻi a me ka lōʻihi o ke ola lawelawe.
Hoʻolālā ʻia nā crucibles nui e kūwela loa, hiki pinepine a hiki i1600°C, e pili ana i ka metala kikoʻī e hana ʻia nei. ʻO kā lākoukiʻekiʻe thermal conductivitye hōʻoia i nā manawa hoʻomehana wikiwiki a me ka ikaika o ka ikehu, he mea nui ia no nāʻoihanaʻoihana nui.
Eia hou, ko lakouka helu haʻahaʻa o ka hoʻonui welae hōʻoia i ka pale ʻana o ka crucible i ka haki ʻana a i ʻole ke kaua ʻana i ka wā e hoʻololi wikiwiki ai ka mahana, e hoʻolilo iā lākou i mea paʻa loa no ka hoʻohana pinepine ʻana i nā hana kaumaha.
I ka hoʻoheheʻe ʻana i ka nui o nā metala, ʻike pinepine ʻia ka crucible i nā slags corrosive a me nā oxide metala hiki ke hōʻino i nā mea haʻahaʻa. Hoʻolālā kūikawā ʻia kā mākou crucibles nui mekiʻekiʻe corrosion kū'ē, e hōʻoia i ka liʻiliʻi o ka ʻaʻahu ʻoiai ke hoʻoheheʻe ʻana i nā metala reactive a i ʻole nā mea hao. ʻO ke kīʻahaʻili o loko paheʻeke pale aku nei i ke kūkulu ʻia ʻana o ke koena metala, e hōʻoia ana i ka kahe ʻana o ka metala i hoʻoheheʻe ʻia me ka ʻole o ka pipiʻi ʻana, e hoʻomaikaʻi ana i ka ninini holoʻokoʻa a hōʻemi i ka ʻōpala metala.
Loaʻa kā mākou crucibles nui i nā ʻano nui, me nā mana mai50 kg a oi 500 kg, ma muli o ke kapuahi kūikawā a me nā koi hoʻoheheʻe metala. Hoʻolālā ʻia kēia mau crucibles e kūpono menā kapuahi hoʻokomo uila, nā kapuahi ahi, anā kapuahi kūʻē, hāʻawi i ka maʻalahi ma waena o nā ʻoihana hana metala like ʻole.
Nā noikomo:
Hoʻokumu ʻia kā mākou crucibles nui e hoʻomanawanui i nā kūlana paʻakikī o nā hana hoʻoheheʻe metala mau. Me ake ola a hiki i ka 100 melt cyclesma muli o ke ʻano metala a me nā kūlana kapuahi, hāʻawi lākou i ka mālama kālā no ka wā lōʻihi ma ka hoʻemi ʻana i ke alapine o nā pani. ʻO kahale paʻae hōʻoiaʻiʻo nō hoʻi i ka hoʻomau ʻana o ka crucible i ke kani, ʻoiai ma hope o ka ʻike pinepine ʻana i ka wela nui a me ke kaumaha mechanical.
Ma ke ʻano he alakaʻi alakaʻi o nā crucibles no nā noi ʻoihana, hana mākou i ka mea nuimaikaʻi, ka lōʻihi, ahoʻokōi kēlā me kēia huahana. Hoʻokumu ʻia kā mākou crucibles nui e hoʻonui i ka huahana a hōʻoia i nā hopena kūlike i nā kaʻina hoʻoheheʻe kiʻekiʻe. Inā ʻoe e holo ana i kahi mea hoʻoheheʻe metala, mea hoʻoheheʻe metala makamae, a i ʻole mea kanu hana hou, hāʻawi kā mākou crucibles nui i ka hiki a me ka hilinaʻi e pono ai e hoʻokō i kāu mau pahuhopu hana.

1. E kūʻai i nā crucibles ma kahi maloʻo a maloʻo e pale ai i ka hoʻoheheʻe ʻana o ka wai a me ka corrosion.
2.E mālama i nā crucibles mai ka lā a me nā kumu wela e pale ai i ka deformation a i ʻole ka haki ʻana ma muli o ka hoʻonui wela.
3. E kūʻai i nā crucibles ma kahi maʻemaʻe a me ka lepo ʻole e pale ai i ka haumia o loko.
4. Inā hiki, e uhi i nā kīʻaha me ka poʻi a i ʻole ka uhi ʻana i mea e pale aku ai i ka lepo, nā ʻōpala, a me nā mea ʻē aʻe mai ke komo ʻana.
5.Avoid stacking a pilaling crucibles ma luna o kekahi i kekahi, no ka mea, hiki i keia ke hana poino i ka lalo.
6. Inā pono ʻoe e lawe a hoʻoneʻe paha i nā crucibles, e mālama iā lākou me ka mālama a pale i ka hāʻule ʻana a i ʻole ke kuʻi ʻana iā lākou i nā ʻili paʻakikī.
7. E nānā pono i nā crucibles no nā hōʻailona o ka pōʻino a i ʻole ka lole, a hoʻololi iā lākou e like me ka mea e pono ai.
Pehea mākou e hōʻoia ai i ka maikaʻi?
Ke hōʻoiaʻiʻo nei mākou i ka maikaʻi ma o kā mākou kaʻina hana o ka hana mau ʻana i kahi laʻana pre-production ma mua o ka hana nui a me ka hana ʻana i kahi nānā hope ma mua o ka hoʻouna ʻana.
No ke aha ʻoe e kūʻai mai ai iā mākou ʻaʻole mai nā mea hoʻolako ʻē aʻe?
ʻO ke koho ʻana iā mākou ma ke ʻano he mea hoʻolako ʻo ia ka loaʻa ʻana o kā mākou mea hana kūikawā a me ka loaʻa ʻana o ke kūkākūkā loea loea a me ka lawelawe maikaʻi loa ma hope o ke kūʻai aku.
He aha nā lawelawe i hoʻohui ʻia e kāu hui?
Ma waho aʻe o ka hana maʻamau o nā huahana graphite, hāʻawi pū mākou i nā lawelawe i hoʻohui ʻia e like me ka anti-oxidation impregnation a me ka mālama ʻana i ka uhi, hiki ke kōkua i ka hoʻonui ʻana i ke ola lawelawe o kā mākou huahana.
