Nā huahana
ʻO ka grit alumina i hoʻopili ʻia i ka ʻeleʻele no ka wili wili pepa one i uhi ʻia i ka abrasive
ʻO ka alumina i hoʻopili ʻia me ka ʻeleʻele/ʻeleʻele corundum, i ʻike nui ʻia ʻo emery, he corundum hana ʻeleʻele i hana ʻia ma ka hoʻoheheʻe ʻana a me ka hōʻemi ʻana i ʻekolu mau mea maka: bauxite, mea kalapona a me nā waihona hao i loko o ka umu arc uila, no laila ka inoa. ʻO kona ʻāpana nui he alumina, a ua hoʻokaʻawale ʻia nā māka e ka nui o ka alumini. ʻO ka haʻahaʻa o ka nui o ka alumini, ʻo ka haʻahaʻa o ka paʻakikī. Hana ʻia ka nui o nā ʻāpana huahana e like me nā kūlana honua a me nā kūlana aupuni, a hiki ke hana ʻia e like me nā koi o ka mea hoʻohana. ʻO ka nui o nā ʻāpana maʻamau he F4 ~ F320, a ʻokoʻa kona ʻano kemika ma muli o ka nui o nā ʻāpana. ʻO ka hiʻohiʻona koʻikoʻi, ʻo ia ka liʻiliʻi o ka nui o ke aniani a pale i ka hopena. No ka mea ua hana ʻia a haki ʻia e kahi mīkini wili ponoʻī, ʻo ka hapa nui o nā ʻāpana he mau ʻāpana poepoe. Maloʻo a maʻemaʻe ka ʻili, a maʻalahi ke hoʻopaʻa me ka mea hoʻopaʻa. Hana ʻia ka alumina i hoʻopili ʻia me ka bauxite papa abrasive ma ke ʻano he mea maka a hoʻohui ʻia me nā mea kōkua. Hoʻomaʻemaʻe ʻia i loko o ka umu arc uila ma kahi mahana kiʻekiʻe ma luna o 2250 ℃. Ma kēia kumu, ua hoʻomaʻemaʻe ʻia e kahi mea hoʻokaʻawale magnetic ikaika kiʻekiʻe a ʻoi aku kona refractoriness ma mua o 1850 ℃. ʻO ka corundum ʻeleʻele i hana ʻia e kā mākou hui he mau ʻano o ka maʻemaʻe kiʻekiʻe, ka crystallization maikaʻi, ka wai ikaika, ka coefficient hoʻonui linear haʻahaʻa a me ke kūpaʻa corrosion. Loaʻa i ka huahana nā ʻano o ka pahū ʻole, ka pauka ʻole, a me ka haki ʻole i ke kaʻina hana noi, a hoʻohana pinepine ʻia i nā abrasives a me nā ʻoihana mea maka refractory.

Nā mea ʻāpala: Huila wili, kāʻei ʻāpala, pepa one, lole ʻāpala, ʻāpana ʻoki, ʻenehana hoʻoheheʻe one, wili, papahele pale ʻaʻahu, ʻoki ʻana i ka wai, nā mea ʻāpala i uhi ʻia, nā mea ʻāpala i hoʻopaʻa ʻia, a pēlā aku.
Nā mea kūpaʻa ʻole: Hiki ke hoʻoheheʻe ʻia, piliki kūpaʻa ʻole, mea ramming, papa slide, nozzle, ladle, mea lining. hoʻolei pololei, a pēlā aku
Ua kapa ʻia ka corundum ʻeleʻele i nā niho ʻoihana: hoʻohana nui ʻia i nā refractories, nā huila wili, a me ke one.
1. Hoʻohana ʻia e hana i nā mea refractory holomua, nā mea i hoʻoheheʻe ʻia, nā pōhaku refractory, a pēlā aku.
2. Ke one ʻana—he paʻakikī waena ko ka abrasive, nui ka nui o ka nui, ʻaʻohe silica manuahi, kiʻekiʻe ke kaumaha kikoʻī, a me ka paʻakikī maikaʻi. He mea hoʻoheheʻe one "aloha i ke kaiapuni" kūpono ia. Hoʻohana nui ʻia ia i nā ʻaoʻao alumini, nā ʻaoʻao keleawe, ke aniani, a me nā jeans i holoi ʻia. Nā ʻōmole kikoʻī a me nā kahua ʻē aʻe;
3. ʻO ka abrasive wili manuahi, i hoʻopili ʻia i ka wili manuahi ma nā kahua o ka paipu kiʻi, ke aniani optical, ka silicon monocrystalline, ka lens, ke aniani wati, ke aniani kristal, ka jade, a pēlā aku. He mea wili kiʻekiʻe ia i hoʻohana pinepine ʻia ma Kina;
4. Nā mea hoʻopalupalu Resin-Nā mea hoʻopalupalu me ke kala kūpono, paʻakikī maikaʻi, paʻakikī, ʻano ʻāpana ʻāpana kūpono a me ka paʻa ʻana o ka lihi, i hoʻopili ʻia i nā mea hoʻopalupalu resin, kūpono ka hopena;
5. Nā mea hoʻopōʻino i uhi ʻia—he mau mea maka nā mea hoʻopōʻino no nā mea hana e like me ka pepa one a me ka gauze;
6. Hoʻopiha hana-hoʻohana nui ʻia no nā ʻāpana paleki kaʻa, nā kaila kūikawā, nā huahana kūkulu kūikawā a me nā kola ʻē aʻe, hiki ke hoʻohana ʻia e like me nā mea pale e like me nā ala holo, nā uapo, nā wahi kaʻa, nā papahele ʻoihana, nā wahi haʻuki, a pēlā aku;
7. ʻO ka media kānana-he kahua noi hou o nā abrasives. Hoʻohana ʻia nā abrasives granular ma ke ʻano he media lalo o ka moena kānana e hoʻomaʻemaʻe i ka wai inu a i ʻole ka wai hoʻoneoneo. He ʻano hou ia o ka mea kānana wai ma ka home a ma waho, kūpono loa no ka hana ʻana i nā mineral metala ʻole ferrous: ʻaila ʻeli lepo kaupaona:
8. ʻO ka ʻoki ʻana i ka hydraulic - hoʻohana i nā mea abrasives ma ke ʻano he mea ʻoki a hilinaʻi i nā jet wai kiʻekiʻe no ka ʻoki maʻamau. Hoʻopili ʻia ia i ka ʻoki ʻana i nā paipu aila (kinoea kūlohelohe), ke kila a me nā ʻāpana ʻē aʻe. He ʻano ʻoki hou, palekana a palekana hoʻi ia no ke kaiapuni.
