Inkqubo yokuvelisa i-aluminium sheet strip ibandakanya la manyathelo alandelayo:

• I-Scalping: ukususa iziphene zomhlaba ezifana nokwahlula, ukufakwa kwe-slag, izibazi, kunye nokuqhekeka kwendawo, kunye nokuphucula umgangatho wephepha. Umatshini we-scalping udibanisa macala omabini kunye nemida ye-slab, kunye nesantya sokugaya se-0.2m / s. Ubukhulu obukhulu obumele bucolwe yi-6mm, kwaye ubunzima bezinto ezilahliweyo ze-aluminiyam eziveliswe yi-383kg nge-slab nganye, kunye nesivuno se-aluminiyam ye-32.8kg.

• Ukufudumeza: i-scalped slab iye ifudunyezwe kwi-pusher-type furnace kubushushu obuyi-350℃ ukuya kuma-550℃ iiyure ezi-5-8. Isithando somlilo sixhotyiswe ngemimandla ye-5, nganye ine-high-flow air circulation fan efakwe phezulu. I-fan isebenza ngesantya se-10-20m / s, idla i-20m3 / min yomoya oxinyiweyo. Kukwakho nezitshisi zegesi zendalo ezingama-20 ezifakwe kwindawo ephezulu yeziko, ezidla malunga ne-1200Nm3/h yerhasi yendalo.

• I-Hot Rough Rolling: i-slab efudumeleyo ifakwe kwi-hot rolling mill, apho idlula i-5 ukuya kwi-13 yokudlula ukuze icuthwe kubukhulu be-20 ukuya kwi-160mm.

• I-Hot Precision Rolling: i-plate egobileyo iqhutywe ngakumbi kwi-hot precision rolling mill, kunye nesantya esiphezulu se-480m / s. Idlula i-10 ukuya kwi-18 yokupasa ukuvelisa iipleyiti okanye iikhoyili ezinobunzima be-2.5 ukuya kwi-16mm.

Inkqubo yokuqengqeleka ebandayo

Inkqubo yokuqengqeleka ilawulwa ziinkqubo zekhompyuter ze-flatness (AFC), ubukhulu (AGC), kunye ne-tension (ATC), kunye nesantya se-5 ukuya kwi-20m / s, kwaye ukuya kwi-25 ukuya kwi-40m / s ngexesha lokuhamba okuqhubekayo. Izinga lokunciphisa ngokubanzi liphakathi kwama-90% ukuya kuma-95%.

• I-Intermediate Annealing: ukuphelisa ukuqina komsebenzi emva kokuqengqeleka okubandayo, ezinye iimveliso eziphakathi zifuna ukukhutshwa. Ubushushu be-annealing buqala kwi-315℃ ukuya kwi-500℃, kunye nexesha lokubamba i-1 ukuya kwiiyure ze-3. Isithando somlilo sifudunyezwa ngombane kwaye sixhotyiswe ngabalandeli be-3 abahamba phambili phezulu, basebenza ngesantya se-10 ukuya kwi-20m / s. Amandla ewonke ezifudumezi yi-1080Kw, kwaye ukusetyenziswa komoya ocinezelweyo yi-20Nm3/h.

• I-Annealing yokugqibela: emva kokuqengqeleka okubandayo, iimveliso zigqithwa ekugqibeleni kwiqondo lobushushu le-260℃ ukuya kwi-490℃, kunye nexesha lokubamba i-1 ukuya kwiiyure ze-5. Umlinganiselo wokupholisa wefoyile ye-aluminiyam kufuneka ube ngaphantsi kwe-15℃/h, kwaye ubushushu bokukhutshwa akufanele budlule kwi-60℃ kwi-foil. Ngobunye ubunzima beekhoyili, ubushushu bokukhutshwa akufanele budlule kwi-100 ℃.

IiNdlela zokuLungiselela ezongezelelweyo

1. Inkqubo yokuzoba: Le nkqubo ibandakanya ukususwa kwegrisi, ukugalela isanti, kunye nokuhlamba amanzi. Kwinkqubo yokudweba iphepha le-aluminium, ubuchule obukhethekileyo befilimu busetyenziswa emva kokunyanga kwe-anodizing. Ngokubanzi, ibrashi yocingo engenastainless okanye ibhanti lesanti yenayiloni enobubanzi obuyi-0.1mm isetyenziselwa ukwenza umaleko wefilimu kumphezulu wephepha le-aluminiyam, inike inkangeleko entle kunye nesilika. Inkqubo yokudweba isinyithi isetyenziselwa ngakumbi ukuveliswa kweemveliso zephepha le-aluminium, ukubonelela zombini i-aesthetics kunye nokumelana nokubola.

2. Inkqubo ye-Etching: Le nkqubo ibandakanya ukugaya nge-jujube wood carbon ukususa igrisi kunye nemikrwelo, ukudala umphezulu we-matte. Emva koko, iphethini iprintwa kusetyenziswa ipleyiti yokushicilela isikrini, kunye neemodeli ze-inki ezifana ne-80-39, 80-59, kunye ne-80-49. Emva kokushicilela, ishidi lomiswe kwi-oven, livalwe ngasemva nge-adhesive esheshayo, kwaye imida ivalwe nge-tape. Iphepha emva koko lenze inkqubo yokubhala. Isicombululo se-aluminiyam ecwengekileyo sine-50% ye-ferric chloride kunye ne-50% yesulfate yobhedu, exutywe nomlinganiselo ofanelekileyo wamanzi, kubushushu obuphakathi kwe-15 ° C ukuya kwi-20 ° C. Ngethuba lokuqhawula, iphepha kufuneka libekwe phantsi, kwaye nayiphi na i-residu ebomvu ephuphumayo kwipatheni kufuneka isuswe ngebrashi. Amabhamuza aya kuvela kumphezulu we-aluminium, ethwele intsalela. Inkqubo yokubhala ithatha malunga ne-15 ukuya kwimizuzu engama-20 ukugqiba.

3. Inkqubo ye-Electrophoretic Coating Process: Le nkqubo ibandakanya la manyathelo alandelayo: ukuhlamba, ukuhlamba amanzi ashushu, ukuhlamba amanzi, ukungathathi hlangothi, ukuhlamba amanzi, i-anodizing, ukuhlamba amanzi, umbala we-electrolytic, ukuhlamba amanzi ashushu, ukuhlamba amanzi, i-electrophoresis, ukuhlamba amanzi kunye nokomisa. Ukongeza kwifilimu ye-anodized, ifilimu yepeyinti ye-acrylic ene-soluble yamanzi ifakwe ngokufanayo kumphezulu weprofayili ngokusebenzisa i-electrophoresis. Oku kwenza ifilimu edibeneyo yefilimu ye-anodized kunye nefilimu yepeyinti ye-acrylic. Iphepha le-aluminium lingena kwitanki ye-electrophoretic enomxholo oqinileyo we-7% ukuya kwi-9%, iqondo lokushisa lika-20 ° C ukuya kuma-25 ° C, i-pH ye-8.0 ukuya kwi-8.8, i-resistiveivity (20 ° C) ye-1500 ukuya kwi-2500Ωcm, i-voltage (DC) of 80 ukuba 25OV, kunye noxinano lwangoku 15 ukuba 50 A/m2. Iphepha lihamba nge-electrophoresis kwi-1 ukuya kwi-3 imizuzu ukufezekisa ubuninzi bokugquma kwe-7 ukuya kwi-12μm.
