Hoʻohana kā mākou hui i ka ʻenehana hana kiʻekiʻe, e kālele ana i nā ʻano like ʻole o ke keleawe a me ka alumini a me nā metala nonferrous ʻē aʻe. I kēia manawa, ʻo nā huahana nui o ka hui: ka pā alumini, ka pahu alumini, ke koʻokoʻo aluminika, nā profiles aluminika, ka alumini ingots, ka uea alumini, ka pā keleawe, ke kaula keleawe, ka uea keleawe keleawe, ke koʻokoʻo keleawe, ka lālani keleawe, ke keleawe keleawe, ka laina keleawe, ka uea keleawe, zinc, lead, tin, magnesium and other non-ferrous metals. Ke hahai nei mākou i ka manaʻo maikaʻi ʻo "One Belt and One Road" Kina, e hana ana i kahi ʻoihana kalepa maikaʻi a me ka hoʻokumu ʻana i kahi kiʻi honua maikaʻi.

ʻO ke kūpaʻa ʻino: ʻo 2.7g/cm³ ka nui o ka ʻaoʻao alumini, e pili ana i ka nui o ke kila, keleawe a me ke keleawe (7.83g/cm³, 8.93g/cm³), a me 1/3. Ma ka hapanui o nā kūlana kaiapuni, e like me ka ea, ka wai (a i ʻole ka brine), kemika ʻaila, a me nā ʻōnaehana kemika he nui, hōʻike ka alumini i ke kūpaʻa maikaʻi loa.

Conductivity: koho pinepine ʻia ka profile alumini no kāna conductivity maikaʻi loa. Ma ke kumu o ke kaupaona like, ua aneane ʻelua ke kiʻekiʻe o ka conductivity o ka alumini ma mua o ke keleawe.

Thermal conductivity: ka thermal conductivity o nā alumini alumini ma kahi o 50-60% o ke keleawe, he mea pono i ka hana ʻana i nā mea hoʻololi wela, nā evaporators, nā mea hoʻomehana, nā mea kuke, a me ke poʻo cylinder a me nā radiators o ke kaʻa.

Non-ferromagnetic: ʻAʻole ferromagnetic nā profiles aluminika, kahi hiʻohiʻona koʻikoʻi o ka ʻoihana uila a me ka uila. ʻAʻole hoʻopau wale ka ʻaoʻao alumini, he mea nui ia no ka hoʻohana ʻana i ka lawelawe ʻana a i ʻole ka hoʻopili ʻana me nā mea inflammable a pahū.

Machinability: maikaʻi loa ka machinability o ka profile alumini. Ma nā ʻano like ʻole o ka alumini alumini a me ka alumini alumini, a ma nā mokuʻāina like ʻole ma hope o ka hoʻopuka ʻana o kēia mau ʻāpana, ʻokoʻa nā hiʻohiʻona machining, e koi ana i nā mea mīkini kūikawā a i ʻole nā ​​ʻenehana.

Formability: ikaika tensile kiko'ī, ikaika hua, ductility, a me ka machining hardening rate e hoʻomalu i ka hoʻololi i ka ʻae ʻia.

(1) mānoanoa kiʻiʻoniʻoni oxide - ʻaʻole lawa ka mānoanoa, hiki i ka ʻili alumini i ka pala a me ka ʻino. ʻAʻole pono e emi iho ka mānoanoa o nā kiʻiʻoniʻoni alumini oxide ma lalo o 10um (micron). ʻO kekahi mau inoa inoa, nā helu wahi, nā laikini hana, nā palapala hōʻoia i nā profile alumini alumini, ka mānoanoa kiʻiʻoniʻoni o 2 a 4um, ʻaʻole nā ​​​​kiʻiʻoniʻoni. Wahi a ka loiloi loea, ʻo kēlā me kēia emi ʻana o ka mānoanoa kiʻiʻoniʻoni 1um oxide, hiki ke hoʻemi i ka hoʻohana ʻana i ka mana no ka ton o nā mea 150.

(2) ka mea hoʻohui kemika, me ka nui o ka alumini alumini, hiki ke hoʻohaʻahaʻa loa i ke kumu kūʻai o ka alumini alumini ʻoihana, akā e alakaʻi ia i ka hoʻohui ʻana i ka alumini alumini hana ʻole, kahi e hoʻoweliweli nui ai i ka ʻenehana palekana.

(3) ka mahele ana o ka mānoanoa o ka like like ka nui kaha kiʻi, a me ka pauku nui, laula, waena lua, akā, paia mānoanoa okoa nui loa, no hoi hiki ke loa okoa, ke kaumaha o kēlā me kēia kumukūʻai e pili ana i ka nui ākea. Eia kekahi, hiki i ka alumini ʻoihana haʻahaʻa ke hoʻemi i kekahi manawa pani, hoʻemi i ka hoʻohana ʻana i nā reagents kemika, a hoʻemi i ke kumukūʻai, akā ua hoʻemi nui ʻia ka pale ʻana o nā mea.

(4) nā mea hana - nā extruders alumini nui, nā mea maka, nā kūlana kaʻina hana, ka mana koʻikoʻi o ka maikaʻi, nā kumukūʻai kiʻekiʻe ma mua o nā mea hana liʻiliʻi, a hiki ke hoʻololi ʻia ka uku hana e 2000-3000 / ton. E hoemi i ka 2-3 yuan/kg.

I nā makahiki i hala iho nei, me ka pae ʻoihana, ua lilo ka ʻoihana alumini a kaulana loa. Hāʻawi ke kūʻai aku i ka ʻokoʻa, ka like ʻole o ke kumukūʻai. ʻAʻole ʻike ʻia ka mea kūʻai aku, mai ke kumukūʻai haʻahaʻa wale nō e koho i ka ʻoihana kūʻai alumini alumini. Ua koi kēia i kekahi mau ʻoihana e koi ana i ka maikaʻi ma mua mai nā haʻahaʻa haʻahaʻa haʻahaʻa a me nā kumukūʻai hana e hōʻoia i ke kūʻai ʻana a me ka haunaele mākeke.

ʻO ka paʻa o ka ʻili o ke keleawe he ʻano hemahema o kekahi coil a me ke keleawe i hoʻopaʻa ʻia i loko o ke kaʻina annealing, ʻo ia ka adhesion ma waena o ka ʻāpana coil a me ka papa.

Nā kumu o ka pili ʻana o ka ʻili:

(1) ʻoʻoleʻa loa ka ʻili o ka ʻili;

(2) nui loa ka ha'alulu a pa'a loa ka ha'alulu;

(3) kiʻekiʻe loa ka mahana annealing a i ʻole ka lōʻihi o ka manawa insulation;

(4) ʻaʻole like ke kaʻina hana hoʻomehana, a ʻokoʻa ka nui o ka hoʻonui wela ma waena o ka papa a me ka papa;

(5) ʻoi aku ka wikiwiki o ka hoʻoheheʻe ʻana i ke kaʻina hana hoʻoluʻu, e loaʻa ana i kahi coefficient ʻokoʻa o ka contraction ma waena o ka leo waho a me loko o ka hoʻoluʻu.

ʻO (2) a me (3) nā kūlana kūpono, a inā loaʻa kekahi o nā kumu ma (4) a me (5) i ka manawa like, hana ʻia ka adhesion.

Nā hana hoʻopau:

(1) pono e haʻahaʻa ka haʻalulu ke lawe ʻia ka leo, ʻoi aku ka nui o ka leo hope ma mua o ka hoʻopili ʻana;

(2) ka wikiwiki o ka hoʻomehana ʻana a me ka hoʻoluʻu pono e mālama pono ʻia i ka hana annealing;

(3) hoʻemi pono i ka mahana annealing a hoʻopōkole paha i ka manawa mālama wela;

(4) hoʻonui pono i ka smoothness o ka roller.

ʻO ka alumini he metala māmā me ka luster silvery, ʻelua mau hiʻohiʻona o kona kūpaʻa corrosion:

(1) ʻoi aku ka maʻemaʻe kiʻekiʻe, ʻoi aku ka maikaʻi o ka corrosion, ua ʻike ʻia ʻo ka alumini maʻemaʻe i ka lewa me ka oxygen, ma luna o ka ʻili o ka alumini e hana i kahi ʻāpana lahilahi o ke kiʻi ʻoniʻoni kūlohelohe maoli, a ʻoi aku ka wikiwiki ma mua o nā kiʻi ʻoniʻoni metala ʻē aʻe i hana ʻia i ʻoi aku ka mānoanoa.

(2) maikaʻi ke kūpaʻa ʻino o ka alumini maʻemaʻe, akā ʻo ka ikaika mechanical maikaʻi ʻole, ka mea i kaupalena ʻia i ka hoʻohana ʻana i ka alumini, no laila, e hoʻohui i ka nui o nā kānaka i ka alumini magnesium, keleawe, zinc a me nā metala ʻē aʻe, i hana ʻia i nā ʻano like ʻole o ke alumini alumini, alumini alumini o ka ikaika mechanical kiʻekiʻe, hoʻomaikaʻi maikaʻi i ka ikaika mechanical o ka alumini, hoʻonui nui i ka laulā noi, ʻoi aku ka maikaʻi o ka alumini, ʻoi aku ka maikaʻi o ka pale ʻana o ka alumini, akā ʻoi aku ka maikaʻi. ʻinoʻino. ʻO ka mea e pono ai ka pale no ka uhi ʻana o ka alumini alumini, alumini alumini me kona ʻāpana liʻiliʻi, maʻalahi i ka mīkini, ikaika mechanical, etc.

Ma hope o ka hoʻomaʻamaʻa ʻana i ka ʻili, loaʻa i ka alumini ke kūpaʻa corrosion kiʻekiʻe, ka ʻokoʻa o ka waihoʻoluʻu, nā pōmaikaʻi he nui, e like me ke ʻano o ka ʻili o ka hale me nā kiʻi ʻoniʻoni ʻē aʻe o ka pā hale waho, e kūkulu i ka hale kala.

Hiki ke hoʻololi i kā mākou mau kumukūʻai ma muli o ka lako a me nā kumu mākeke ʻē aʻe. E hoʻouna mākou iā ʻoe i kahi papa inoa kūʻai hou ma hope o ka hoʻopili ʻana o kāu hui iā mākou no ka ʻike hou aku.

ʻAe, koi mākou i nā kauoha honua āpau e hoʻomau i ka nui o nā kauoha liʻiliʻi. Inā ʻoe e ʻimi nei e kūʻai hou aku akā ma ka liʻiliʻi liʻiliʻi, paipai mākou iā ʻoe e nānā i kā mākou pūnaewele.
