ʻO ke kaʻina hana o ka ʻāpana pepa alumini e pili ana i nā pae aʻe:

• Scalping: e wehe i nā hemahema o ka ʻili e like me ka hoʻokaʻawale ʻana, ka hoʻokomo ʻana i ka slag, nā ʻōpala, a me nā māwae ʻili, a hoʻomaikaʻi i ka maikaʻi o ka ʻili o ka lau. Hoʻopili ka mīkini scalping i nā ʻaoʻao ʻelua a me nā ʻaoʻao o ka pā, me ka wikiwiki o ka wili o 0.2m/s. ʻO ka mānoanoa kiʻekiʻe loa e wili ʻia ʻo 6mm, a ʻo ke kaumaha o nā ʻōpala alumini i hana ʻia he 383kg no ka papa, me ka hua alumini o 32.8kg.

• Hoʻomaʻamaʻa: Hoʻomaʻamaʻa ʻia ka pā scalped i loko o kahi kapuahi pusher-type ma kahi mahana o 350 ℃ a 550 ℃ no 5-8 mau hola. Ua hoʻolako ʻia ka umu ahi me nā ʻāpana 5, kēlā me kēia me kahi peʻa lele lele kiʻekiʻe i kau ʻia ma luna. Hoʻohana ka peʻahi i ka wikiwiki o 10-20m / s, e hoʻopau ana i 20m3 / min o ka ea paʻa. Aia kekahi 20 mau mea puhi kinoea maoli i hoʻokomo ʻia ma ka ʻaoʻao o luna o ka umu ahi, e ʻai ana ma kahi o 1200Nm3/h o ke kinoea maoli.

• Wela Rough Rolling: ua hānai ʻia ka pā wela i loko o ka hale wili wela e hoʻohuli ʻia, kahi e hana ai ʻo 5 a 13 mau ala e hoʻemi ʻia i ka mānoanoa o 20 a 160mm.

• ʻO ka ʻōwili wela wela: ua hoʻomaʻamaʻa hou ʻia ka pā i ʻōwili ʻia i loko o kahi mīkini wili wela wela, me ka wikiwiki o ka ʻōwili ʻana o 480m/s. Loaʻa iā ia he 10 a 18 mau ala e hana ai i nā papa a i ʻole nā ​​coils me ka mānoanoa o 2.5 a 16mm.

Ke Kaʻina ʻOli ʻAi

Hoʻohana ʻia ke kaʻina ʻōwili anuanu no nā coils alumini me nā kikoʻī aʻe:

• Mānoanoa: 2.5 a 15mm

• Laulā: 880 a 2000mm

• Anawaena: φ610 a φ2000mm

• Kaumaha: 12.5t

Aia ke kaʻina hana i kēia mau ʻanuʻu:

• ʻO Cold Rolling: ʻo ka alumini wela i ʻōwili ʻia me ka mānoanoa o 2-15mm ua ʻōwili ʻia i loko o kahi wili anu hiki ʻole ke hoʻohuli ʻia no 3-6 mau ala, e hōʻemi ana i ka mānoanoa i 0.25 a 0.7mm. Hoʻomalu ʻia ke kaʻina ʻōwili e nā ʻōnaehana kamepiula no ka palahalaha (AFC), ka mānoanoa (AGC), a me ka hoʻopaʻapaʻa (ATC), me ka wikiwiki o ka ʻōwili ʻana o 5 a 20m/s, a hiki i 25 a 40m/s i ka wā e ʻōwili mau ai. ʻO ka nui o ka ho'ēmiʻana ma waena o 90% a 95%.

• Intermediate Annealing: e hoʻopau i ka paʻakikī o ka hana ma hope o ka ʻōwili anuanu, pono kekahi mau huahana waena i ka annealing. ʻO ka mahana annealing mai 315 ℃ a 500 ℃, me ka manawa paʻa o 1 a 3 mau hola. ʻO ka umu annealing ua hoʻomehana ʻia a hoʻolako ʻia me 3 kiʻekiʻe kiʻekiʻe ma luna, e hana ana ma ka wikiwiki o 10 a 20m/s. ʻO ka nui o ka mana o nā mea hoʻomehana he 1080Kw, a he 20Nm3 / h ka hoʻohana ʻana i ka ea.

• Hoʻopili hope: ma hope o ka ʻōwili anu, e hoʻopili ʻia nā huahana ma kahi mahana o 260 ℃ a 490 ℃, me ka manawa paʻa o 1 a 5 mau hola. ʻO ka nui o ka hoʻoluʻu o ka pahu alumini e emi iho ma mua o 15 ℃ / h, a ʻaʻole pono ka mahana hoʻokuʻu ma mua o 60 ℃ no ka foil. No nā mānoanoa ʻē aʻe o nā coils, ʻaʻole pono ka mahana hoʻokuʻu ma mua o 100 ℃.

Kaʻina Hoʻopau

Hoʻopau ʻia ke kaʻina hana e hoʻokō i nā kikoʻī i makemake ʻia o nā huahana alumini. Loaʻa iā ia nā ʻanuʻu:

• Nā kikoʻī o nā huahana i hoʻopau ʻia:

• Mānoanoa: 0.27 a 0.7mm

• Laulā: 880 a 1900mm

• Anawaena: φ610 a φ1800mm

• Kaumaha: 12.5t

• Hoʻonohonoho lako:

• 2000mm Cross Cutting Line (2 a 12mm) - 2 sets

• 2000mm Tension Leveling Line (0.1 a 2.5mm) - 2 sets

• 2000mm Cross Cutting Line (0.1 a 2.5mm) - 2 sets

• 2000mm Mānoanoa Plate Straightening Line - 2 sets

• 2000mm Coil Automatic Packaging Line - 2 sets

• MK8463×6000 CNC Roll Grinding Machine - 2 mau ʻāpana

• Kaʻina hana a me nā ʻāpana:

• Laina Hana Hana Kea: ʻokiʻoki pololei i nā alumini alumini a me nā alumini alumini me ka mānoanoa o 2 a 12mm, me ka lōʻihi o 11m.

• ʻO ka hoʻopaʻapaʻa ʻana ʻo Prka laina oduction: ua hoʻokau ʻia ka coil alumini i ka hoʻopaʻapaʻa e nā ʻōwili tension, me ka ikaika o ka 2.0 a 20 kN. Ke hele nei ma waena o nā pūʻulu he nui o nā ʻōwili wili liʻiliʻi i hoʻonohonoho ʻia, e ʻae ana i ka hoʻopololei ʻana a me ke kulou ʻana e hoʻomaikaʻi i ka palahalaha o ke kaula. Hoʻohana ka laina i ka wikiwiki a hiki i 200m / min.

• ʻO ka Laina Hana Hoʻopono Papa Mānoanoa: hoʻonoho ʻia nā ʻōwili ma kahi kihi i ke kuhikuhi o ka neʻe ʻana o ka huahana. ʻElua a ʻekolu mau ʻōwili paʻi ikaika nui i alakaʻi ʻia e nā kaʻa kaʻa i ka ʻaoʻao hoʻokahi, a me kekahi mau ʻōwili kaomi passive liʻiliʻi ma kekahi ʻaoʻao, e kaʻa ana ma o ke kuʻekuʻe i hana ʻia e ke koʻokoʻo a i ʻole ka paipu. Hiki ke hoʻololi ʻia kēia mau ʻōwili liʻiliʻi i mua a i hope paha i ka manawa like a i ʻole kaʻawale e hoʻokō i ka koi koi o ka huahana. Ke hele nei ka huahana i ka laina laina mau a i ʻole ka neʻe ʻana i ka neʻe ʻana, ka hopena i ka hoʻopaʻa ʻana, ka piko, a me ka hoʻopalapala ʻana i nā deformations, a loaʻa i ke kumu o ka hoʻopololei. ʻO ka ikaika hoʻopololei o ka laina hana he 30MN.

Nā Hana Hana Hou

1. Kaʻina kaha kiʻi: ʻO ke kaʻina hana e pili ana i ka degreasing, ke one, a me ka holoi wai. I ke kaʻina hana kiʻi kiʻi alumini, hoʻohana ʻia kahi ʻenehana kiʻiʻoniʻoni kūikawā ma hope o ka mālama anodizing. ʻO ka mea maʻamau, hoʻohana ʻia kahi kāʻei ʻili kila kila a i ʻole ke kāʻei sanding nylon me ke anawaena o 0.1mm e hana i kahi papa kiʻiʻoniʻoni ma ka ʻili o ka pepa alumini, e hāʻawi iā ia i kahi hiʻohiʻona maikaʻi a silika. Hoʻohana nui ʻia ke kaʻina hana kiʻi metala i ka hana ʻana i nā huahana pepa alumini, e hāʻawi ana i ka aesthetics a me ke kūpaʻa corrosion.

2. Ke Kaʻina Hana: ʻO ke kaʻina hana e wili me ka kalapona lāʻau jujube e wehe i ka momona a me nā ʻōpala, e hana ana i kahi ʻili matte. A laila, paʻi ʻia kahi ʻano hoʻohana me ka pā paʻi pale, me nā hiʻohiʻona inika e like me 80-39, 80-59, a me 80-49. Ma hope o ka paʻi ʻana, hoʻomaloʻo ʻia ka pepa i loko o ka umu, hoʻopaʻa ʻia ma hope me ka hoʻopili koke, a hoʻopaʻa ʻia nā ʻaoʻao me ka lipine. A laila hele ka pepa i ka hana etching. ʻO ka hopena etching no ka pepa alumini he 50% ferric chloride a me 50% copper sulfate, i hui pū ʻia me ka nui o ka wai, ma kahi mahana ma waena o 15°C a 20°C. I ka wā o ka etching, pono e waiho ʻia ka lau i palahalaha, a ʻo nā koena ʻulaʻula e kahe ana mai ke kumu hoʻohālike e hoʻoneʻe ʻia me kahi pulupulu. E puka mai ana na bula ma ka ili alumina, e lawe ana i ke koena. Ma kahi o 15 a 20 mau minuke e hoʻopau ai ke kaʻina hana etching.

3. Electrophoretic Coating Process: Aia ka hana i kēia mau ʻanuʻu: degreasing, holoi wai wela, holoi wai, neutralization, holoi wai, anodizing, holoi wai, kala electrolytic, holoi wai wela, holoi wai, electrophoresis, holoi wai, a maloʻo. Ma waho aʻe o ke kiʻi ʻoniʻoni anodized, ua hoʻopili like ʻia kahi kiʻi pena kiʻi wai-soluble i ka ʻili o ka ʻaoʻao ma o ka electrophoresis. Hoʻokumu kēia i kahi kiʻi ʻoniʻoni o ke kiʻi anodized a me ke kiʻi pena acrylic. Hoʻokomo ka pepa alumini i loko o kahi pahu electrophoretic me kahi mea paʻa o 7% a 9%, kahi mahana o 20 ° C a 25 ° C, pH o 8.0 a 8.8, resistivity (20 ° C) o 1500 a 2500Ωcm, volta (DC) o 80 a 25OV, a me ka nui o keia manawa o 15 a 50 A/m2. Hoʻopili ka pepa i ka electrophoresis no 1 a 3 mau minuke e hoʻokō i ka mānoanoa o ka uhi ʻana o 7 a 12μm.
