Njira yopangira pepala la aluminiyamu imaphatikizapo izi:

• Scalping: kuchotsa zolakwika zapamtunda monga tsankho, kuphatikizika kwa slag, zipsera, ndi ming'alu yapamtunda, ndikuwongolera mawonekedwe a pepalalo. Makina a scalping amapangira mbali zonse ndi m'mphepete mwa slab, ndi liwiro la mphero la 0.2m / s. Kukula kwakukulu koyenera kugayidwa ndi 6mm, ndipo kulemera kwa zidutswa za aluminiyamu zopangidwa ndi 383kg pa slab, ndi zokolola za aluminium 32.8kg.

• Kutentha: scalped slab ndiye kutenthedwa mu ng'anjo pusher pa kutentha 350 ℃ mpaka 550 ℃ kwa 5-8 maola. Ng'anjoyo ili ndi madera a 5, iliyonse ili ndi fan yothamanga kwambiri yomwe imayikidwa pamwamba. Kukupiza kumagwira ntchito pa liwiro la 10-20m / s, kuwononga 20m3 / min ya mpweya woponderezedwa. Palinso zoyatsira 20 za gasi zomwe zimayikidwa kumtunda kwa ng'anjo, zomwe zimawononga pafupifupi 1200Nm3/h ya gasi.

• Hot Rough Rolling: slab yotenthedwa imadyetsedwa mu mphero yotentha yosinthika, pomwe imadutsa 5 mpaka 13 kuti ichepetse mpaka makulidwe a 20 mpaka 160mm.

• Kugudubuzika Kwambiri Kwambiri: mbale yopindikayo imakonzedwanso mu mphero yotentha yotentha, ndi liwiro lalikulu la 480m/s. Imadutsa 10 mpaka 18 kuti ipange mbale kapena ma coils okhala ndi makulidwe a 2.5 mpaka 16mm.

Cold Rolling Process

Njira yozizira yopukutira imagwiritsidwa ntchito popanga ma coil aluminiyamu ndi izi:

• makulidwe: 2.5 mpaka 15mm

• M'lifupi: 880-2000mm

• M'mimba mwake: φ610 mpaka φ2000mm

• Kulemera kwake: 12.5t

Ndondomekoyi imakhala ndi izi:

• Cold Rolling: zitsulo zotayidwa zotentha za aluminiyamu zokhala ndi makulidwe a 2-15mm ndizozizira zokulungidwa mumphero yosasinthika yosasinthika kwa mphindi 3-6, kuchepetsa makulidwe ake mpaka 0.25 mpaka 0.7mm. Kugudubuza kumayendetsedwa ndi makina apakompyuta a flatness (AFC), makulidwe (AGC), ndi kupanikizika (ATC), ndi liwiro la 5 mpaka 20m / s, mpaka 25 mpaka 40m / s panthawi yopitirirabe. Mlingo wochepetsera nthawi zambiri umakhala pakati pa 90% mpaka 95%.

• Intermediate Annealing: kuthetsa kuuma ntchito pambuyo ozizira kugudubuza, mankhwala ena wapakatikati amafuna annealing. Kutentha kwa annealing kumachokera ku 315 ℃ mpaka 500 ℃, ndi nthawi yogwira 1 mpaka 3 ola. Ng'anjo yowotcherayo imatenthedwa ndi magetsi ndipo imakhala ndi mafani 3 othamanga kwambiri pamwamba, akugwira ntchito pa liwiro la 10 mpaka 20m/s. Mphamvu zonse za heaters ndi 1080Kw, ndi wothinikizidwa mpweya mowa ndi 20Nm3/h.

• Final Annealing: pambuyo kugudubuzika kozizira, zinthuzo zimadutsa pa kutentha kwa 260 ℃ mpaka 490 ℃, ndi nthawi yogwira 1 mpaka 5 maola. Kuzizira kwa zojambulazo za aluminiyamu kuyenera kukhala kosakwana 15 ℃ / h, ndipo kutentha kwazitsulo kuyenera kusapitirira 60 ℃ kwa zojambulazo. Pa makulidwe ena a ma coils, kutentha kotulutsa sikuyenera kupitirira 100 ℃.

Njira Yomaliza

Njira yomaliza ikuchitika kuti mukwaniritse zofunikira za zinthu za aluminiyamu. Zimaphatikizapo njira zotsatirazi:

• Zomwe Zatsirizidwa:

• makulidwe: 0.27-0.7mm

• M'lifupi: 880-1900mm

• M'mimba mwake: φ610 mpaka 1800mm

• Kulemera kwake: 12.5t

• Kukonzekera kwa Zida:

• 2000mm Cross Cutting Line (2 mpaka 12mm) - 2 seti

• 2000mm Tension Leveling Line (0.1 mpaka 2.5mm) - 2 seti

• 2000mm Cross Cutting Line (0.1 mpaka 2.5mm) - 2 seti

• 2000mm Thick Plate Straightening Line - 2 seti

• 2000mm Coil Automatic Packaging Line - 2 seti

• MK8463 × 6000 CNC Pereka Akupera Makina - 2 mayunitsi

• Njira ndi Parameters:

• Cross Cutting Production Line: kudulidwa kolondola kwa aluminiyamu ndi ma aluminium alloy coil okhala ndi makulidwe a 2 mpaka 12mm, okhala ndi kutalika kwa 11m.

• Tension Leveling PrOduction Line: koyilo ya aluminiyamu imakhudzidwa ndi mipukutu yolimba, yokhala ndi mphamvu ya 2.0 mpaka 20 kN. Imadutsa m'magulu angapo amizere yaying'ono yopindika yokonzedwa mosinthana, kulola kutambasula ndi kupindika kuti mzerewo ukhale wosalala bwino. Mzerewu umagwira ntchito pa liwiro la 200m / min.

• Thick Plate Straightening Production Line: mipukutuyo imayikidwa pakona komwe kumayendera komwe chinthucho chikuyenda. Pali mipukutu iwiri kapena itatu ikuluikulu yogwira ntchito yoyendetsedwa ndi ma mota omwe amazungulira mbali imodzi, ndi magudumu angapo ang'onoang'ono ang'onoang'ono ang'onoang'ono ang'onoang'ono ang'onoang'ono ang'onoang'ono ang'onoang'ono omwe amasuntha mbali inayo, akuyenda mokangana chifukwa cha ndodo yozungulira kapena chitoliro. Mipukutu yaying'ono iyi imatha kusinthidwa kutsogolo kapena kumbuyo nthawi imodzi kapena padera kuti mukwaniritse kupsinjika komwe kumafunikira. Chogulitsacho chimayenda mosalekeza mozungulira kapena mozungulira, zomwe zimapangitsa kupsinjika, kupindika, ndi kupunduka kosalala, pamapeto pake kukwaniritsa cholinga chowongola. Mphamvu yowongoka ya mzere wopanga ndi 30MN.

Njira Zina Zopangira

1. Njira Yojambulira: Njirayi imaphatikizapo kuchotsa mafuta, kupukuta mchenga, ndi kutsuka madzi. Pojambula pepala la aluminiyumu, njira yapadera ya filimu imagwiritsidwa ntchito pambuyo pa mankhwala a anodizing. Nthawi zambiri, burashi yachitsulo chosapanga dzimbiri kapena lamba wa mchenga wa nayiloni wokhala ndi mainchesi 0.1mm imagwiritsidwa ntchito popanga filimu wosanjikiza pamwamba pa pepala la aluminiyamu, ndikupangitsa kuti iwoneke bwino komanso ngati silky. Kujambula kwachitsulo kumagwiritsidwa ntchito kwambiri popanga zinthu za aluminiyamu, zomwe zimapereka kukongola komanso kukana dzimbiri.

2. Etching Njira: Njirayi imaphatikizapo kugaya ndi kaboni wamatabwa a jujube kuti achotse mafuta ndi zokala, kupanga pamwamba pa matte. Kenako, chojambula chimasindikizidwa pogwiritsa ntchito mbale yosindikizira, yokhala ndi mitundu ya inki monga 80-39, 80-59, ndi 80-49. Pambuyo pa kusindikiza, pepalalo limawuma mu uvuni, losindikizidwa kumbuyo ndi zomatira pompopompo, ndipo m'mphepete mwake amasindikizidwa ndi tepi. Pambuyo pake, pepalalo limagwira ntchito yojambula. The etching solution for aluminium sheets are 50% ferric chloride and 50% copper sulfate, wosakaniza ndi madzi okwanira, pa kutentha kwapakati pa 15°C mpaka 20°C. Pa etching, pepalalo liyenera kuikidwa lathyathyathya, ndipo zotsalira zofiira zomwe zikusefukira kuchokera pa chitsanzo ziyenera kuchotsedwa ndi burashi. Mavuvu amatuluka pamwamba pa aluminiyumu, kunyamula zotsalira. Ntchito yojambula imatenga pafupifupi mphindi 15 mpaka 20 kuti ithe.

3. Electrophoretic Coating Process: Njirayi imaphatikizapo njira zotsatirazi: kupukuta, kuchapa madzi otentha, kutsuka madzi, neutralization, kutsuka madzi, anodizing, kutsuka madzi, electrolytic coloring, kutsuka madzi otentha, kutsuka madzi, electrophoresis, kutsuka madzi, ndi kuyanika. Kuphatikiza pa filimu ya anodized, filimu ya utoto wa acrylic yosungunuka madzi imayikidwa mofanana pamwamba pa mbiriyo kudzera mu electrophoresis. Izi zimapanga filimu yophatikiza ya anodized film ndi acrylic paint film. Pepala la aluminiyamu limalowa mu thanki ya electrophoretic yokhala ndi 7% mpaka 9%, kutentha kwa 20 ° C mpaka 25 ° C, pH ya 8.0 mpaka 8.8, resistivity (20 ° C) ya 1500 mpaka 2500Ωcm, voltage (DC) wa 80 kuti 25OV, ndi kachulukidwe panopa 15 mpaka 50 A/m2. Tsambalo limakumana ndi electrophoresis kwa mphindi 1 mpaka 3 kuti likwaniritse makulidwe a 7 mpaka 12μm.
