graphite crucibleʻO ke kīʻaha graphite silikonihe ipu i hana ʻia me ka graphite ma ke ʻano he mea maka, no laila he kūpaʻa kiʻekiʻe kiʻekiʻe loa a hiki ke hoʻohana ʻia i ka hoʻoheheʻe metala ʻoihana. No ka laʻana, i ke ola o kēlā me kēia lā, hiki iā ʻoe ke hoʻomaopopo i ka nui o nā mea kālepa ma nā kuaʻāina e hoʻoponopono i nā ipu alumini a i ʻole nā ipu alumini. ʻO nā mea hana a lākou e hoʻohana ai he crucibles. Hoʻokomo ʻia nā ʻāpana alumini i loko o ka ipuhao a hoʻomoʻa ʻia i ke ahi a hoʻoheheʻe ʻia i loko o ka wai alumini, ninini hou i ka māwae o ka ipu hao, hoʻomāalili, a laila hiki ke hoʻohana ʻia. Eia nō naʻe, hoʻohana ʻia nā crucibles graphite a me ka silicon carbide crucibles i ka ʻoihana. Ma waena o lākou, loaʻa i nā crucibles graphite maikaʻi ka thermal conductivity, akā ua maʻalahi lākou i ka oxidation a loaʻa ka nui o ka pōʻino. ʻOi aku ka nui a me ka lōʻihi o ke ola lawelawe ʻana ma mua o nā crucibles graphite Silicon carbide. Ua loea mākou i ke kūʻai aku a me ka hana ʻana i nā crucibles no 40 mau makahiki. ʻO nā kīʻaha graphite a mākou e hana ai he kūpono ia no ka hoʻoheheʻe ʻana i ke gula, ke kālā, ke keleawe, ka hao, ka aluminika, ka zinc, a me ka tin, a me nā ʻano hana hoʻoheheʻe a me ka hoʻomehana ʻana e like me ka coke, ka ʻaila ʻaila, ke kinoea maoli, ka umu uila, etc. ʻO nā crucibles graphite a mākou e hana nei, mahalo nui ʻia e nā mea kūʻai hou a me nā mea kahiko no kā lākou hana maikaʻi a paʻa. Hoʻokomo pū mākou i ka ʻenehana hana hoʻomohala holomua - ke ʻano hana hoʻoheheʻe isostatic pressure crucible - e pili ana i ka mākeke a me nā pono o ka mea kūʻai aku, A me kahi ʻōnaehana hoʻāʻo hōʻoia koʻikoʻi, ʻo ka silicon carbide crucible i hana ʻia e kēia ʻenehana nā hiʻohiʻona o ke kiʻekiʻe leo kiʻekiʻe. thermal conductivity, acid and alkali corrosion resistance, kiʻekiʻe wela ikaika, a kiʻekiʻe oxidation kū'ē. ʻO kona ola lawelawe he 3-5 mau manawa o nā crucibles graphite. I ka manawa like, mālama ia i ka wahie a hoʻemi i ka ikaika o ka hana no nā limahana. ʻO ke kumu kūʻai o nā mea hoʻoheheʻe isostatic hoʻōla i ka ikehu a me nā mea hoʻolaʻa isostatic pressure crucibles e hoʻohana nui ʻia kēia huahana i ka hoʻoheheʻe ʻana i nā metala non-ferrous.
Hiki ke hoʻohana ʻia nā kīʻaha graphite i loko o nā kapuahi like ʻole, e like me nā kapuahi uila, nā kapuahi uila, nā umu ahi, nā kiln, a me nā mea ʻē aʻe, no ka hoʻoheheʻe ʻana i ke gula, kālā, keleawe, hao, aluminika, zinc, tin, a me nā mea hoʻohui. ʻO ke ala hoʻokomo pololei no ka pahu graphite a me ka pahu silika carbide
1. Pono ke kumu o ka graphite crucible e like a oi aku paha ke anawaena e like me ka lalo o ka crucible, a o ke kiekie o ka crucible platform e pono e oi aku mamua o ka nozzle e pale aku i ke ahi mai ka pipi ana maluna o ka crucible.
2. I ka hoʻohana ʻana i nā pōhaku lepo refractory e like me nā papa ʻaina, pono e hoʻohana ʻia nā pōhaku lepo pōʻai, he palahalaha a ʻaʻole piʻo. Mai hoʻohana i ka hapalua a i ʻole nā mea pōhaku lepo ʻole. ʻOi aku ka maikaʻi o ka hoʻohana ʻana i nā papa graphite crucible i lawe ʻia mai.
3. Pono e waiho ʻia ka papa ʻaina ma ke kikowaena o ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana, me ka pauka coke, ka lehu mauʻu, a i ʻole ka pulupulu refractory ma ke ʻano he pad e pale aku ai i ka pili ʻana ma waena o ka crucible a me ka papa ʻaina. Ma hope o ke kau ʻana i ka crucible, pono e pae.
4. Pono ka nui ma waena o ka ipuhao a me ke kino o ka umu ahi, a ʻo ka mamao ma waena o ka ipuhao a me ka pā hoʻoheheʻe e kūpono, ma kahi o 40mm a ʻoi aku paha.
I ka wā e hoʻouka ai i kahi kīʻaha nuku i loko o ka umu ahi, pono e mālama ʻia kahi āpau ma kahi o 30-50MM ma waena o ka lalo o ka nozzle crucible a me ka brick refractory, ʻaʻohe mea e waiho ʻia ma lalo. Pono e hoʻomaʻemaʻe ʻia ka nozzle a me ka paia o ka umu me ka pulupulu refractory. Pono e hoʻopaʻa ʻia ka pā o ka umu ahi a hoʻopaʻa ʻia ka crucible me ka pahu corrugated me ka mānoanoa o kahi o 3mm e like me ka wahi hoʻonui wela ma hope o ka hoʻomehana ʻana.
Hōʻike nui ʻia ka ʻenehana hana o nā crucibles graphite i nā ʻano e like me ka formula, nā mea maka, nā lako hana, a me nā ʻenehana. Ma ke ʻano o ke koho ʻana i nā mea maka, hoʻohana nui mākou i ka pālolo refractory, aggregates, graphite maoli, a me nā mea ʻē aʻe. ʻO ke ala ma o ka hoʻoheheʻe ʻia ʻana, ka hoʻoheheʻe ʻana, a me ka hana lima, ʻo ia ka graphite molding. Ma hope o ka hana ʻana i ka hana ʻana, pono e hoʻomanaʻo e hoʻomaloʻo. Ma hope o ka nānā ʻana, ua kūpono ia, a hiki ke hoʻonani ʻia nā huahana kūpono
