    ʻO ka crucible kahi ipu hao e hoʻohana ai i ka metala no ka hoʻoheheʻe ʻana i loko o ka umu. ʻO kēia ka mea kiʻekiʻe kiʻekiʻe, ʻoihana ʻoihana crucible i hoʻohana ʻia e ka ʻoihana foundry ʻoihana.

    He aha ia hana:

    Pono ka crucible no ka pale ʻana i nā wela wela i loaʻa i nā metala hehee. ʻOi aku ka kiʻekiʻe o ka mea hoʻoheheʻe ʻia ma mua o ko ka metala i hoʻoheheʻe ʻia a he ikaika maikaʻi kona ʻoiai ke wela keʻokeʻo.

    Hiki ke hoʻohana i ka ipu hao i hana ʻia no ka hoʻoheheʻe ʻana i nā metala e like me ka zinc a me ka aluminika, no ka mea, hehee kēia mau metala ma kahi mahana ma lalo o ke kila. Eia naʻe, pilikia ka scaling (fllaking) o ka ʻili o loko o ka ipu hao. Hiki i kēia unahi ke hoʻohaumia i ka heheʻe a me ka lahilahi o nā paia kīʻaha me ka wikiwiki. E hoʻohana nā crucibles kila inā ʻoe e hoʻomaka wale ana a mai noʻonoʻo ʻoe i ka hana ʻana i ka scaling.

    ʻO nā mea refractory maʻamau i hoʻohana ʻia i ka hana crucible ʻo ka pālolo-graphite, a me ke kalapona i hoʻopaʻa ʻia i ka silicon-carbide. Hiki i kēia mau mea ke kū i nā wela kiʻekiʻe loa ma ka hana hoʻokumu maʻamau. Loaʻa i ka Silicon carbide ka mea i hoʻohui ʻia he mea paʻa loa.

    Ua helu ʻia kā mākou mau kīʻaha Clay Graphite Bilge Shape no 2750 °F (1510 °C). E mālama lākou i ka zinc, aluminika, keleawe / keleawe, kālā a me ke gula. Ua ʻōlelo ka mea hana hiki ke hoʻohana ʻia no ka hao hao. Hana ʻia ma ʻAmelika Hui Pū ʻIa!

    Nā ʻano kīʻaha:

    Ua like ke ʻano o ka pahu bilge (“B” Shape) e like me ka pahu waina. ʻO ke anawaena "bilge" ke anawaena o ka crucible ma kona wahi ākea loa. Inā ʻaʻohe anawaena bilge i hōʻike ʻia a laila ʻo ke anawaena o luna ka laulā kiʻekiʻe.

    Wahi a kekahi lula o ka manamana nui, hāʻawi ka # o kahi kīʻaha "bilge" i kona hiki ke hana ma nā paona alumini. No ke keleawe a me ke keleawe e hoʻohana i 3 manawa i ka crucible #. No ka laʻana, hiki i kahi kīʻaha #10 ke paʻa ma kahi o 10 paona alumini a me 30 paona keleawe.

    Hoʻohana maʻamau ʻia kā mākou "B" shape crucibles e nā mea leʻaleʻa a me nā casters pinepine. He ʻano kiʻekiʻe kēia, ʻoi aku ka lōʻihi o ka pahu pāʻoihana.

    E nānā i nā papa ma lalo e ʻike i ka nui kūpono no kāu hana.

    Pehea e hoʻohana ai:

    Pono e lawelawe ʻia nā kīʻaha a pau me nā ʻōpiʻi kūpono (mea hana hāpai). Hiki ke hōʻino a i ʻole ka hāʻule ʻole ʻana o kahi kīʻaha i ka manawa ʻino loa.

    Hiki ke waiho ʻia kahi pahu pahu pahu ma waena o ka ipuhao a me ke kumu umu ma mua o ka hoʻomehana ʻana. E ʻā ana kēia, e waiho ana i kahi ʻāpana kalapona ma waena a pale i ke kīʻaha mai ka pipili ʻana i lalo o ka umu. ʻO kahi uhi o Plumbago (Carbon Black) hana like.

    ʻOi aku ka maikaʻi o ka hoʻohana ʻana i kahi kīʻaha ʻokoʻa no kēlā me kēia ʻano metala e pale aku i ka haumia. E hōʻoia hoʻi e hoʻokaʻawale loa i ka crucible ma hope o ka hoʻohana ʻana. Hiki ke hoʻonui ʻia ka metala i hoʻopaʻa ʻia i loko o ka crucible i ka hoʻomehana hou ʻana a luku iā ia.

    E ʻoluʻolu e hoʻonā i nā crucibles hou a i ʻole nā ​​​​mea i waiho ʻia i loko o kahi waihona. E puhi i ka ipu hao ʻole no 2 mau hola ma 220 F (104 C). (Use adequate ventilation. New crucibles will smoke as the glaze sets.) A laila e puhi i ka ipu hao ʻole i kahi wela ʻulaʻula. E ʻae i ka crucible e hoʻolili i ka lumi wela i loko o ka umu ma mua o ka hoʻohana ʻana. Pono e hahai ʻia kēia kaʻina hana no nā kīʻaha hou a pau a no kēlā me kēia kīʻaha i ʻike ʻia paha i nā kūlana pulu i ka waiho ʻana.

    E mālama i nā kīʻaha a pau ma kahi maloʻo. Hiki i ka maʻu ke hoʻohāhā i ka ipuhao i ka wela. Inā ua mālama ʻia no kekahi manawa, ʻoi aku ka maikaʻi o ka hana hou ʻana i ka tempering.

    ʻO nā kīʻaha silikoni carbide ka mea liʻiliʻi loa e komo i ka wai i ka waiho ʻana a ʻaʻole pono e hoʻomaʻamaʻa ʻia ma mua o ka hoʻohana ʻana. He manaʻo maikaʻi e puhi i kahi kīʻaha hou i kahi wela ʻulaʻula ma mua o kona hoʻohana mua ʻana e kipaku a hoʻopaʻakikī i nā uhi a me nā mea hoʻopaʻa.

    Pono e waiho ʻia ka mea i loko o ka crucible LOA loa. ʻAʻole "hoʻopaʻa" i kahi kīʻaha, no ka mea, e hoʻonui ʻia ka mea i ka hoʻomehana ʻana a hiki ke haki i ka ceramic. Ke hoʻoheheʻe ʻia kēia mea i loko o kahi "kuʻekuʻe", e hoʻouka pono i nā mea hou aku i loko o ka puddle no ka hoʻoheheʻe ʻana. (NĀ MEA: Inā loaʻa kekahi maʻa ma luna o ka mea hou, e hiki mai ana ka PAHU mahu). Eia hou, mai hoʻopaʻa paʻa i ka metala. E hoʻomau i ka hānai ʻana i ka mea i loko o ka hehee a hiki i ka hoʻoheheʻe ʻia ʻana o ka nui i makemake ʻia.

    WARNING!!!: He pōʻino nā crucibles. He pōʻino ka hoʻoheheʻe ʻana i ka metala i loko o ka ipu hao. He pōʻino ka ninini ʻana i ka metala i loko o nā mole. Hiki ke hāʻule ka pahu me ka ʻike ʻole ʻole. Hiki i nā crucibles ke komo i nā hemahema huna i nā mea a me ka hana ʻana i hiki ke alakaʻi i ka hāʻule, pōʻino waiwai, hōʻeha pilikino, hōʻeha i ka poʻe e kū ana a me ka pohō o ke ola.

    BCS ʻO kahi poloka kumu kahi paepae wela kiʻekiʻe i hoʻohana ʻia e hoʻāla i kahi kīʻaha i ka wahi wela o kahi umu.

    He aha ia hana:

    Hoʻohana maʻamau ʻia kahi poloka kumu i loko o ka umu ahi i hoʻokuʻu ʻia e hoʻokiʻekiʻe i ke kīʻaha i luna i ʻole e pā pololei ka lapalapa ahi i loko o ka paia lahilahi o kahi kīʻaha.

    ʻO ka hoʻokiʻekiʻe ʻana i ka crucible hiki iā ia ke komo i loko o ka "'āpana wela" o ka umu. ʻOiai ua komo ka lapalapa ahi i loko o ke kino o ka umu ahi ma lalo, ʻo ka wahi wela loa mai waena a i luna. Aia ma kēia ʻāpana e hoʻomehana ʻia nā paia o ka umu ahi e ke kinoea holo ʻoi loa. ʻO ka loaʻa ʻana o nā ʻaoʻao o ka crucible ma kēia ʻāina e hoʻolalelale i ka hoʻomehana maikaʻi loa mai ke kahawai ʻea huikau a me ka hoʻomālamalama wela o nā paia o loko o ka umu ahi.

    Pehea e hoʻohana ai:

    Pono ke kiʻekiʻe o ka ʻāpana kumu e hoʻohālikelike ʻia ka lapalapa ahi me ka piko o ka poloka. ʻOi aku ka maikaʻi inā ʻoi aku ka kiʻekiʻe o ka piko o ka poloka ma mua o ke komo ʻana o ke ahi. ʻO ka mea āu e makemake ʻole ai, ʻo ka paʻi ʻana o ke ahi i nā ʻaoʻao ʻoi aku ka lahilahi o ka ipu. Hiki ke ʻae ʻia inā pā ka lapalapa i ka ʻāpana ʻoi aku ka mānoanoa o lalo o ka crucible no ka mea ʻaʻole maʻalahi kēia ʻāpana i ke kinoea.
