E wehewehe kikoʻī i ke ʻano o ka hoʻolei ʻana o nā ʻanuʻu koʻokoʻo alumini no ʻoe

1. E koho i ka wela hoolei pololei
ʻO ka mahana hoʻoheheʻe kūpono kekahi kumu nui e hana ai i ka maikaʻi kiʻekiʻenā pahu alumini. He mea maʻalahi ka hana ʻana i nā hemahema e like me ka palaoa a me ka hulu aniani ke kiʻekiʻe ka mahana.
Ma hope o ka hoʻomaʻemaʻe ʻana i ka palaoa, hiki ke hoʻonui ʻia ka mahana forging o ka wai 6063 alumini alumini, ma waena o 720-740 ℃, no ka mea:
(1) Lilo ka alumini wai ma hope o ka hoʻomaʻemaʻe ʻana i ka palaoa a me ka crystallization solidification maʻalahi. (2) Aia kahi wai-paʻa ʻelua-phase nui loa i ka crystallization mua o ka pahu alumini i ka forging. ʻO ka mahana forging kiʻekiʻe he haiki loa ka ʻāpana, kahi kūpono i ka pakele ʻana o ke kinoea i kāpae ʻia mai ka crystallization mua. ʻOiaʻiʻo, ʻaʻole hiki ke kiʻekiʻe loa ka mahana, ʻoi aku ka kiʻekiʻe o ka wela forging e hōʻemi i ka manawa kūpono o ka mea hoʻomaʻemaʻe palaoa a lilo i mea nui.
2. Ke loaʻa nā kūlana, hoʻomaʻamaʻa piha, hoʻomaloʻo i ka ʻōnaehana hoʻolei e like me ka pahu kahe a me ka pā shunt e pale ai i ka hopena o ka wai a me ka alumini wai e hana i ka absorption hydrogen.
3. Ma ka alumini bar forging, e ho'āʻo e pale i ka turbulence a me ka olokaʻa o ka wai alumini, mai hoʻohana wale i nā mea hana e hoʻoulu ai i ka alumini wai i loko o ka pahu kahe a me ka pā shunt, i hiki ai i ka alumini wai i ka ʻili o ke kiʻi oxide ma lalo o ka pale o ka paʻa kahe i loko o ka crystallizer crystallization.
ʻO kēia no ka mea e hoʻokaʻawale ka ʻili o ka alumini oxide kiʻi ʻoniʻoni i nā mea hana agitation wai alumini a me nā kahe kahe wai, e hana i kahi oxidation hou, i ka manawa like, ke kiʻi ʻoniʻoni i komo i ka alumini wai.
Hōʻike ka noiʻi i ka ikaika adsorption ikaika o ke kiʻi oxide, aia ka 2% wai, i ka wā i komo ai ke kiʻi oxide i ka alumini wai, ka wai i loko o ke kiʻi oxide a me ka hopena alumini wai, e hana ana i ka hydrogen absorption a me ka slag.
4. ʻO ka alumini bar alumini wai kānana, kānana he ala kūpono e wehe ai i ka slag nonmetal i loko o ka wai alumini, i ka hana ʻana o 6063 alumini alumini, maʻamau me ka multi-layer glass fiber filtration filtration a i ʻole ka kānana ceramic filter plate filtration, ʻaʻohe mea o ke ʻano kānana i hoʻohana ʻia.
I mea e hōʻoia ai i ka kānana maʻamau o ka alumini wai, pono e hoʻoneʻe ʻia ka alumini wai mai ka scum ili ma mua o ka kānana ʻana, no ka mea he maʻalahi ka scum o ka ʻili e hoʻopaʻa i ka mīkini kānana o ka mea maka, i hiki ʻole ke hoʻokō ʻia ka kānana, ʻo ke ala maʻalahi e wehe i ka ʻili o ka alumini wai ʻo ka hoʻonohonoho ʻana i kahi pā slag i loko o ka pahu kahe, no laila e wehe ʻia ka alumini wai ma mua o ka holoi ʻana.
