Kugadzira Maitiro eAluminium Sheet Strip
Iyo yekugadzira maitiro ealuminium sheet strip inosanganisira anotevera matanho:
Scalping: kubvisa kuremara kwepamusoro sekuparadzana, kuiswa kwe slag, mavanga, uye kuputika kwepamusoro, uye kuvandudza kunaka kwepamusoro pepepa. Iyo scalping muchina inogaya mativi ese uye mipendero ye slab, ine chigayo chinomhanya che 0.2m/s. Ukobvu hwepamusoro hunofanira kugayiwa i6mm, uye huremu hwezvimedu zvealuminium zvinogadzirwa i383kg per slab, negoho realuminium re32.8kg.
Kupisa: iyo scalped slab inozodziiswa mupusher-mhando yevira patembiricha ye350 ℃ kusvika 550 ℃ kwemaawa 5-8. Choto chine nzvimbo 5, imwe neimwe ine yakakwira-kuyerera kwemhepo inotenderera fan yakaiswa pamusoro. Iyo fan inoshanda nekumhanya kwe10-20m / s, ichidya 20m3 / min yemhepo yakamanikidzwa. Kune zvakare makumi maviri anopisa gasi echisikigo akaiswa pamusoro pechoto, achipedza 1200Nm3/h yegasi rechisikigo.
Kupisa Rough Rolling: iyo inopisa slab inodyiswa mune inodzoserwa inopisa inotenderedza mill, iyo inopinda 5 kusvika 13 inopfuura kuti ideredzwe kuhukobvu hwe20 kusvika 160mm.
Kupisa Precision Rolling: iyo rough yakakungurutswa ndiro inogadziridzwazve mune inopisa chaiyo inokungurutsa mill, ine yakanyanya kukunguruka kumhanya ye480m/s. Inopfuura gumi kusvika gumi nemasere inogadzira mahwendefa kana makoiri ane ukobvu hwe2.5 kusvika 16mm.
Cold Rolling Process
Iyo inotonhora yekutenderedza maitiro inoshandiswa kune aruminiyamu coils ine anotevera maratidziro:
Ukobvu: 2.5 kusvika 15mm
Kureba: 880 kusvika 2000mm
Dhayamita: φ610 kusvika φ2000mm
Kurema: 12.5t
Iyo nzira ine matanho anotevera:
Cold Rolling: maaruminiyamu anopisa akakungurutswa makoiri ane ukobvu hwe2-15mm anotonhora akakungurutswa mune isingadzokeke inotonhorera inotenderedza guyo kwema 3-6 kupfuura, ichidzikisa ukobvu kusvika 0.25 kusvika 0.7mm. Iyo rolling process inodzorwa nemakomputa masisitimu e flatness (AFC), ukobvu (AGC), uye tension (ATC), ine rolling yekumhanya ye5 kusvika 20m/s, uye inosvika 25 kusvika 40m/s panguva yekutenderera. Chiyero chekudzikisa kazhinji chiri pakati pe90% kusvika 95%.
Intermediate Annealing: kubvisa kuoma kwebasa mushure mekutonhora, zvimwe zvigadzirwa zvepakati zvinoda annealing. Iyo tembiricha yekudziya inotangira pa315 ℃ kusvika pa500 ℃, ine nguva yekubata ye1 kusvika kumaawa matatu. Choto chekuvharisa chinodziiswa nemagetsi uye chine 3 high-flow fans pamusoro, chichishanda nekumhanya kwe10 kusvika 20m/s. Simba rose rezvidziviriro i1080Kw, uye kushandiswa kwemhepo kwakamanikidzwa i20Nm3/h.
Final Annealing: mushure mekutonhora kukunguruka, zvigadzirwa zvinopinda kwekupedzisira annealing patembiricha ye260 ℃ kusvika 490 ℃, ine nguva yekubata ye1 kusvika kumaawa mashanu. Mwero wekutonhora wealuminium foil unofanirwa kunge uri pasi pe15 ℃/h, uye tembiricha yekuburitsa haifanirwe kudarika 60 ℃ yefoiri. Kune mamwe makubvu emakoiri, tembiricha yekuburitsa haifanirwe kudarika 100 ℃.
Kupedzisa Maitiro
Iyo yekupedzisa maitiro inoitwa kuti izadzise yaidiwa zvirevo zvezvigadzirwa zvealuminium. Inosanganisira matanho anotevera:
Zvinotsanangurwa zveFinished Products:
Ukobvu: 0.27 kusvika 0.7mm
Kureba: 880 kusvika 1900mm
Dhayamita: φ610 kusvika φ1800mm
Kurema: 12.5t
Equipment Configuration:
2000mm Muchinjikwa Wekucheka Mutsetse (2 kusvika 12mm) - 2 seti

Maitiro uye Parameters:
Muchinjikwa Kucheka Kugadzira Mutsetse: chaiwo muchinjika-kucheka kwealuminium uye aruminiyamu alloy coils ane ukobvu hwe2 kusvika 12mm, nehurefu hurefu hwe11m.
Tension Leveling Production Mutsara: iyo aluminium coil inoiswa pasi pekunetsekana netension rolls, ine tension simba re2.0 kusvika 20 kN. Iyo inopfuura nemaseti akawanda ediki-dhayamita kubhenda rolls akarongwa neimwe nzira, achibvumira kutambanudza uye kukotama kuvandudza kupfava kwetambo. Mutsara unoshanda nekumhanya kunosvika 200m/min.
Gobvu Plate Kururamisa Kugadzira Mutsetse: iwo marongero akamisikidzwa pakona kuenda kune iyo nzira yekufamba kwechigadzirwa. Kune maviri kana matatu mahombe anoshanda epressure rolls anofambiswa nemamotor anotenderera akananga kudivi rimwe, uye akati wandei madiki madiki anotenderera anotenderera kune rimwe divi, achitenderera kuburikidza nekukwesha kunokonzerwa neinotenderera tsvimbo kana pombi. Aya madiki madiki anogona kugadziridzwa kumberi kana kumashure panguva imwe chete kana zvakasiyana kuti awane kudzvanywa kunodiwa kwechigadzirwa. Chigadzirwa chacho chinoenderera mberi mutsara kana kutenderera kutenderera, zvichikonzera kudzvanya, kukotama, uye kupepeta deformation, pakupedzisira kuzadzisa chinangwa chekutwasanuka. Simba rekururamisa remutsetse wekugadzira i30MN.
Kuwedzera Magadzirirwo Techniques
Kudhirowa Maitiro: Iyo nzira inosanganisira degreasing, jecha, uye kugeza mvura. Mune aluminium pepa rekudhirowa maitiro, yakasarudzika firimu nzira inoshandiswa mushure meanodizing kurapwa. Kazhinji, simbi isina Stainless waya bhurashi kana bhandi rejecha renaironi rine dhayamita ye0.1mm rinoshandiswa kugadzira firimu layer pamusoro pepepa realuminium, richipa chitarisiko chakanaka uye chine silky. Iyo simbi yekudhirowa maitiro iri kuwedzera kushandiswa mukugadzirwa kwealuminium sheet zvigadzirwa, ichipa zvese aesthetics uye corrosion kuramba.
Etching Process: Iyo nzira inosanganisira kukuya nejujube huni kabhoni kuti ubvise girizi uye zvikweshwa, kugadzira matte pamusoro. Zvadaro, patani inodhindwa uchishandisa chidzitiro chekudhinda ndiro, ine ingi mienzaniso yakadai se80-39, 80-59, uye 80-49. Mushure mekudhinda, pepa racho rinoomeswa muchoto, rakavharwa kumashure nekunamatira pakarepo, uye mipendero yakavharwa ne tepi. Pepa racho rinobva raita etching process. Iyo etching solution yealuminium sheet ine 50% ferric chloride uye 50% copper sulfate, yakasanganiswa nehuwandu hwakakodzera hwemvura, patembiricha iri pakati pe15°C kusvika 20°C. Panguva yekucheka, pepa rinofanira kuiswa rakadzikama, uye chero masara matsvuku anoputika kubva pamuenzaniso anofanira kubviswa nebhurashi. Mabhuru achabuda pamusoro pealuminium, achitakura zvakasara. Iyo etching process inotora angangoita 15 kusvika 20 maminetsi kuti apedze.
Electrophoretic Coating Process: Iyo nzira inosanganisira matanho anotevera: degreasing, kugeza mvura inopisa, kugeza mvura, neutralization, kugeza mvura, anodizing, kugeza mvura, electrolytic coloring, kugeza mvura inopisa, kugeza mvura, electrophoresis, kugeza mvura, uye kuomesa. Mukuwedzera kune anodized firimu, mvura-soluble acrylic pendi firimu inoshandiswa zvakafanana pamusoro pepamusoro peprofile kuburikidza ne electrophoresis. Izvi zvinoumba firimu rinoumbwa reanodized firimu uye acrylic pendi firimu. Pepa realuminium rinopinda mu electrophoretic tank ine zvinhu zvakasimba zve 7% kusvika 9%, tembiricha ye20 ° C kusvika 25 ° C, pH ye8.0 kusvika 8.8, resistivity (20 ° C) ye1500 kusvika 2500Ωcm, voltage (DC) ye80 kusvika ku25OV, uye ikozvino density ye15 kusvika 50 A/m2. Iyo shiti inopinda electrophoresis kwemaminetsi 1 kusvika ku3 kuti iwane ukobvu hwekuputira hwe7 kusvika 12μm.
