Kev tsim cov txhuas yob ntawv ci 3003 koom nrog ntau txheej txheem sib txuas ua ke sib txuas nrog kev txawj ntse metall Hauv qab no yog cov kauj ruam-ntawm-kauj ruam txheej txheem:
Alloy Npaj:
Raw aluminium (thawj lossis rov ua dua tshiab) yog melted nyob rau hauv cov chaw ua hluav taws xob ntawm ~ 750 degree. Manganese, hlau, thiab lwm cov ntsiab lus ntxiv kom ua tiav 3003 muaj pes tsawg leeg. Lub Molten hlau yog degassed kom tshem tawm impurities li hydrogen.
Chaw ua casuming:
Lub Mollot Alloy tau raug pov rau hauv cov kab loj loj (ntawm cove ncaj dauve ua kom direct casting) lossis yob txuas ntxiv (rau thinner gauges). Homogenization annealing (ntawm 500-600 degree) kom ua kom cov teeb tsa microstructure.
Kub Rolling:
Ingots yog preheated rau 400-500 degree thiab dov rau hauv tuab daim ntawv (2-6 mm). Cov kauj ruam no tsoo cov qauv cam khwb cia, txhim kho ductility.
Cuav Dab:
Cov ntawv txheeb dhau los ua tiav colling colling kis kom txo cov tuab (li nyias li {}}. 006 hli). Nruab nrab annaling (300-400 degree) relieves kev ntxhov siab thiab restores formancion.
Cov txheej txheem ua tiav:
Txoj kab: Cov coil yog txiav mus rau hauv nqaim loj siv ntau lub ntsej muag.
Nto Kho: Ntawv ci tej zaum yuav ua kom zoo, laminated, lossis anodized rau cov ntawv thov tshwj xeeb (piv txwv li, tiv thaiv corrosion corrosion rau HVAC fins).
Npau taws: Qhov kawg cov khoom siv tau hloov kho ntawm annealing (o-npau taws) lossis ib nrab txias ua haujlwm (H-Tempers zoo li H14 lossis H18).
Kev Tswj Xyuas Zoo:
Thickness, tensile lub zog, thiab nto yam tsis xws luag yog kev sim nruj heev. ASTM B479 thiab Ams 4036 tus qauv tswj hwm kev thev taus.
Cov kev sib tw tseem ceeb xws li tswj cov ris tsho sib txawv thaum dov thiab minimizing saum npoo zoo li pinholes. Advanced Mills siv cov gauge tswj thiab kev tswj hwm nruj-xob los ua kom muaj kev sib xws.
Cov khoom kawg sib xyaw ua ke nrog cov khoom haum siab nrog cov khoom siv, cov lus qhia ntawm kev xav tau los ntawm Aerospace-cov khoom ntim khoom lag luam. Kev nruam zoo li ntxaib-yob casting thiab eco-friendly recycling txuas ntxiv txhim kho kom muaj kev ruaj khov hauv 3003 ntawv ci ntau lawm.
