ʻO ka hana hoʻomaʻemaʻe ʻana o ka kānana puʻu ceramic

Hiki i ke kānana ʻōhua seramika ke hoʻopili pono i nā hoʻokomo ʻana i loko o ka metala wai a hoʻomaikaʻi i ka maikaʻi o ka hoʻolei ʻana a me ka hoʻoulu ʻana, ʻehā mau ʻano hana nui e hoʻomaʻemaʻe maikaʻi i ka metala wai.
(1) Mekini hoʻokaʻawale lana
Ma hope o ka waiho ʻana i kakānana ʻōhua seramikai loko o ka ninini nenoaiu, ke kū'ē o ka wai metala kahe kahe ana, a me ka wai metala i loko o ka ninini nenoaiu piha i ka moku'āina, no laila, e pāʻani i ka slag blocking hana o ka ninini nenoaiu. I ka manawa like, ʻo ke kahe wai i hoʻokuʻu ʻia mai ka sprue pololei e throttled ma o ka kānana, noho pōkole ka metala wai i loko o ka sprue pololei, a ʻo ka slag me ka liʻiliʻi liʻiliʻi e lana a hoʻokaʻawale, hiki ke hana i ka hopena like o ka injection lalo. ʻōnaehana ninini. Ke hele ka metala wai ma ka
E hoʻomau i ka ninini ʻana i nā kānana ceramic foam, ma ka ʻaoʻao hoʻokahi, ka mānoanoa o ka slag liʻiliʻi e lana ana, ma ka ʻaoʻao ʻē aʻe, e hōʻemi a hoʻopau paha i ka manawa eddy.
(2) "Kāna kānana" mechanical
kānana ʻōhua seramikaʻO ke kahawai curved, hiki ke hoʻopaʻa ʻia i ka mīkini paʻa, ʻoi aku ka nui ma mua o ka lua kānana i loko o ka slag entrapment i hopu ʻia ma ka hopena inlet o ka kānana. Me ka hoʻonuiʻana i ka helu o nā mea hoʻokomo i hopuʻia, i loko o ka hopena inlet kānana o kaʻili o ka hoʻokumuʻiaʻana o nā'āpana nui o ka hoʻokomoʻana i hanaʻia e ka "cake kānana". ʻO ka "keke" e hoʻoheheʻe ʻia ka wai, no laila ʻoi aku ka liʻiliʻi o nā inclusions ma mua o ka nui o ka kānana e hopu ʻia i loko o ka "keke".
(3) Adsorption mechanical
Hoʻokomo ʻia ke kānana i loko o ka lua o ke ala kea a i ʻole sprue i loko, ʻo ka hana kānana he kānana hohonu, i ka wā e hiki mai ai ke kaula mua o ka metala i hoʻoheheʻe ʻia ma ka inlet hope ʻili o ka kānana, e hopena i ka kahe wai a me ka ʻōpala mesh adsorption hanana, ma ka like. I ka manawa, e hele mai ka wai kahe "impact", ʻo ka kānana ponoʻī he hopena blocking, kekahi o nā haumia i kekahi kaomi, ma muli o nā haumia a me ka ʻūhū paʻa. mesh seramika. Kekahi mau inclusions ma lalo o kekahi puʻe, ma muli o ka inclusions a me ka paʻa pahu ceramic mesh kiʻi like me ka "maʻamau grid correspondence" pilina, i mea maʻalahi i ka lubricate a me ka adsorption, keia adsorption mea nui non-koho nui-molecular papa o physical. adsorption ka mea nui, inclusions i loko o ke kānana mesh frame adsorption papa ma ka papa, a hiki i ka blockage.
(4) Ka hopena hoʻoponopono
Ke kahe ka mea hooheheeia ma ke kanana hu'ahua seramika, ua maheleia i na apana liilii he nui o ke kahe o ke kaula, a ua uuku kona anawaena, i emi mai ai ka helu Reynolds (Re=vD/γ), i mea e emi ai ka wai. i ke kahe lamina. I ka wa o ka wai metala i loko o ka laminar kahe moku'āina, ma muli o ka manoanoa o ka mea hooheheeia ua oi aku mamua o ka density o inclusions, i inclusions i lawa manawa e lana e wehe, pela kakānana ʻōhua seramikahiki no hoi ke kokua i ke kea-hoolei channel slag blocking, ninini nenoaiu ma hope o kau i ka kānana, ka wai metala kahe kū'ē mahuahua, i loko o ke keʻa-hoʻolele ala i ke kahe o ka wai metala ua oluolu e hana i ka piha kahe, a hana i ka. kahe kahe haʻahaʻa, conducive i ka lana o inclusions a paʻa i loko o ka ʻO ka ʻili luna o ke kahawai kea.
