Inqubo yokukhiqiza i-aluminium sheet strip ihlanganisa lezi zinyathelo ezilandelayo:

• I-Scalping: ukususa amaphutha angaphezulu njengokuhlukaniswa, ukufakwa kwe-slag, izibazi, nokuqhekeka kwendawo, nokuthuthukisa ikhwalithi yangaphezulu yeshidi. Umshini we-scalping ugaya izinhlangothi zombili namaphethelo we-slab, ngesivinini sokugaya esingu-0.2m/s. Ubukhulu obukhulu okufanele bugaywe bungu-6mm, kanti isisindo sezinsalela ze-aluminium ezikhiqiziwe singama-383kg nge-slab ngayinye, nesivuno se-aluminium esingu-32.8kg.

• Ukushisisa: i-scalped slab bese ibaselwa esithandweni sohlobo lwe-pusher ezingeni lokushisa elingu-350℃ kuya ku-550℃ amahora angu-5-8. Isithando somlilo sifakwe izindawo ezi-5, ngayinye inefeni yokugeleza komoya ephezulu efakwe phezulu. Ifeni isebenza ngesivinini esingu-10-20m/s, idla u-20m3/min womoya ocindezelwe. Kukhona nezibasi zegesi yemvelo ezingama-20 ezifakwe engxenyeni engenhla yesithando somlilo, zidla cishe u-1200Nm3/h wegesi yemvelo.

• I-Hot Rough Rolling: i-slab eshisayo ifakwa esigayweni esishisayo esiphendukayo, lapho sidlula ama-5 kuya ku-13 ukuze sincishiswe sibe ugqinsi lwama-20 kuya ku-160mm.

• I-Hot Precision Rolling: ipuleti eligoqiwe liphinde licutshungulwe endaweni yokugaya enembayo enembayo, enesivinini esiphezulu esingu-480m/s. Idlula amaphasi ayi-10 kuye kwayi-18 ukuze ikhiqize amapuleti noma amakhoyili anogqinsi luka-2.5 kuya ku-16mm.

I-Cold Rolling Process

Inqubo yokugoqa ebandayo isetshenziselwa amakhoyili e-aluminium anezincazelo ezilandelayo:

• Ubukhulu: 2.5-15mm

• Ububanzi: 880-2000mm

• Ububanzi: φ610 ukuze φ2000mm

• Isisindo: 12.5t

Inqubo iqukethe izinyathelo ezilandelayo:

• I-Cold Rolling: amakhoyili e-aluminium ashisayo aginqiwe anogqinsi oluyi-2-15mm abanda agingqelwe endaweni ebandayo engaphendukiyo egoqayo izikhathi ezi-3-6, ehlisa ukujiya ku-0.25 kuya ku-0.7mm. Inqubo yokugingqika ilawulwa amasistimu ekhompyutha wokucaba (AFC), ukujiya (AGC), kanye ne-tension (ATC), enesivinini sokuginqika esingu-5 ukuya ku-20m/s, futhi sifike ku-25 kuya ku-40m/s ngesikhathi sokugingqika okuqhubekayo. Izinga lokunciphisa ngokuvamile liphakathi kuka-90% kuya ku-95%.

• I-Intermediate Annealing: ukuqeda ukuqina komsebenzi ngemva kokugoqa okubandayo, eminye imikhiqizo ephakathi idinga ukuhushulwa. Izinga lokushisa le-anneal lisukela ku-315℃ ukuya ku-500℃, nesikhathi sokubamba ihora eli-1 kuye kwangama-3. Isithando somlilo sishisiswe ngogesi futhi sifakwe amafeni ageleza aphezulu angu-3 phezulu, asebenza ngesivinini esingu-10 kuya ku-20m/s. Amandla ama-heaters angu-1080Kw, kanti umoya ocindezelwe wu-20Nm3/h.

• I-Final Annealing: ngemva kokugoqeka okubandayo, imikhiqizo ifakwa emazingeni okushisa angama-260℃ kuya ku-490℃, nesikhathi sokubamba amahora angu-1 kuye kwayi-5. Izinga lokupholisa le-aluminium foil kufanele libe ngaphansi kuka-15℃/h, futhi izinga lokushisa lokukhipha akufanele lidlule ku-60℃ ku-foil. Ngobunye ubukhulu bamakhoyili, izinga lokushisa lokukhipha akufanele lidlule i-100 ℃.

Inqubo yokuqeda

Inqubo yokuqeda yenziwa ukuze kuzuzwe imininingwane oyifunayo yemikhiqizo ye-aluminium. Kubandakanya izinyathelo ezilandelayo:

• Imininingwane Yemikhiqizo Eqediwe:

• Ubukhulu: 0.27-0.7mm

• Ububanzi: 880-1900mm

• Ububanzi: φ610 ukuze φ1800mm

• Isisindo: 12.5t

• Ukucushwa kwesisetshenziswa:

• 2000mm Cross Cutting Line (2 kuya 12mm) - 2 amasethi

• 2000mm Tension Leveling Line (0.1 kuya ku-2.5mm) - amasethi ama-2

• 2000mm Cross Cutting Line (0.1 kuya 2.5mm) - 2 amasethi

• 2000mm Thick Plate Straightening Line - 2 amasethi

• 2000mm Coil Automatic Packaging Line - amasethi ama-2

• I-MK8463×6000 CNC Roll Grinding Machine - amayunithi ama-2

• Inqubo namapharamitha:

• I-Cross Cutting Production Line: ukunqanyulwa okuqondile kwamakhoyili e-aluminium kanye ne-aluminium alloy anogqinsi oluyi-2 kuya ku-12mm, anobude obuyi-11m.

• I-Tension Leveling PrI-oduction Line: ikhoyili ye-aluminiyamu ibhekene nokushuba kwamaroli okudonsa ngamandla, amandla okudonsa ka-2.0 kuya ku-20 kN. Idlula kumasethi amaningi amaroli okugoba anobubanzi obuncane ahlelwe ngokushintshana, okuvumela ukwelula nokugoba ukuze kuthuthukiswe ukucaba komugqa. Ulayini usebenza ngesivinini esingafika ku-200m/min.

• I-Thick Plate Straightening Production Line: amaroli abekwe nge-engeli eya lapho ukunyakaza komkhiqizo. Kunamaroli amabili noma amathathu amakhulu okucindezela okusebenzayo ashayelwa amamotho azungeza ohlangothini olufanayo, kanye namagingqika amaningana amancane okucindezela okuguquguqukayo ngakolunye uhlangothi, azungezayo ngenxa yokungqubuzana okubangelwa induku ejikelezayo noma ipayipi. Le miqulu emincane ingalungiswa iye phambili noma emuva ngesikhathi esisodwa noma ngokuhlukana ukuze kuzuzwe ukuminyanisa okudingekile komkhiqizo. Umkhiqizo uthola ukunyakaza okulandelanayo noma okujikelezayo okuqhubekayo, okuholela ekucindezelweni, ukugoba, kanye nokukhubazeka okuyisicaba, ekugcineni kufinyelele inhloso yokuqondisa. Amandla okuqondisa omugqa wokukhiqiza angama-30MN.

Amasu Okucubungula Engeziwe

1. Inqubo Yokudweba: Le nqubo ihilela ukususa amafutha, ukugalela isihlabathi, nokugeza amanzi. Enqubweni yokudweba i-aluminium sheet, inqubo ekhethekile yefilimu isetshenziswa ngemva kokwelashwa kwe-anodizing. Ngokuvamile, ibhulashi lensimbi engagqwali noma ibhande lesanding enayiloni elinobubanzi obungu-0.1mm lisetshenziselwa ukwakha ungqimba lwefilimu phezu kweshidi le-aluminium, lilenze libukeke kahle futhi linosilika. Inqubo yokudweba insimbi iya ngokuya isetshenziswa ekukhiqizeni imikhiqizo yeshidi le-aluminium, ihlinzeka kokubili ubuhle nokumelana nokugqwala.

2. I-Etching Process: Le nqubo ihilela ukugaya nge-jujube wood carbon ukususa amafutha kanye nokuklwebheka, ukwakha i-matte surface. Bese, iphethini iphrintwa kusetshenziswa ipuleti lokuphrinta lesikrini, elinamamodeli ayinki afana no-80-39, 80-59, kanye no-80-49. Ngemuva kokuphrinta, ishidi liyomiswa kuhhavini, livalwe ngemuva nge-adhesive esheshayo, futhi imiphetho ivalwe nge-tape. Ishidi libe selingena kwinqubo yokuqopha. Isixazululo se-etching seshidi le-aluminium siqukethe u-50% we-ferric chloride kanye no-50% we-copper sulfate, exutshwe nenani elifanele lamanzi, ezingeni lokushisa eliphakathi kuka-15°C kuya ku-20°C. Ngesikhathi se-etching, ishidi kufanele libekwe phansi, futhi noma yiziphi izinsalela ezibomvu ezichichima iphethini kufanele zisuswe ngebhulashi. Amabhamuza azovela endaweni ye-aluminium, ethwala okusele. Inqubo yokufaka ithatha cishe imizuzu eyi-15 ukuya kwengama-20 ukuqeda.

3. Inqubo ye-Electrophoretic Coating: Inqubo ihlanganisa izinyathelo ezilandelayo: ukuhlanza, ukugeza kwamanzi ashisayo, ukugeza amanzi, ukungathathi hlangothi, ukugeza amanzi, i-anodizing, ukugeza amanzi, umbala we-electrolytic, ukugeza kwamanzi ashisayo, ukugeza amanzi, i-electrophoresis, ukugeza amanzi, nokomisa. Ngaphandle kwefilimu ye-anodized, ifilimu yepende ye-acrylic encibilikayo emanzini isetshenziswa ngokufanayo ebusweni bephrofayela ngokusebenzisa i-electrophoresis. Lokhu kwakha ifilimu ehlanganisiwe yefilimu ye-anodized nefilimu yepende ye-acrylic. Ishidi le-aluminium lingena ethangini le-electrophoretic elinokuqukethwe okuqinile okungu-7% kuya ku-9%, izinga lokushisa elingu-20°C kuya ku-25°C, i-pH engu-8.0 kuya ku-8.8, ukumelana (20°C) kuka-1500 kuya ku-2500Ωcm, i-voltage (DC) ka-80 kuya ku-25OV, kanye nokuminyana kwamanje kuka-15 kuya ku-50 A/m2. Ishidi lithola i-electrophoresis imizuzu engu-1 kuya kwemi-3 ukuze lifinyelele ukushuba kokumboza okungu-7 kuya ku-12μm.
