① Kev txiav txim siab ntawm tag nrho cov txheej txheem yog hais txog tag nrho cov deformation degree ntawm cov ntawv ci los ntawm recrystallization annealing rau dov tawm cov khoom tiav. Feem ntau hais lus, tag nrho cov kev ua tiav ntawm 1 series tuaj yeem ncav cuag ntau dua 99%, thiab qee cov khoom ntawm 8 series kuj tuaj yeem ncav cuag tus nqi no. Txawm li cas los xij, tag nrho cov txheej txheem ntawm aluminium alloy foil feem ntau qis dua 90%.
② Kev txiav txim siab ntawm kev ua tiav yog qhov tseem ceeb ntawm cov txheej txheem dov. Rau cov khoom lag luam ntshiab aluminium series, qhov kev ua tiav tuaj yeem ncav cuag 65%. Rau thawj kis tom qab annealing ntawm lub billet, nws tsis pom zoo kom siv tus nqi siab heev, feem ntau nyob ib ncig ntawm 50%.
Rolling thickness
Cov txheej txheem ntsuas thickness rau txhuas ntawv yob feem ntau suav nrog eddy tam sim no thickness ntsuas, isotope ray thickness ntsuas, thiab X-ray thickness ntsuas. X-ray thickness ntsuas yog txoj kev siv ntau tshaj plaws hauv aluminium ntawv ci, tshwj xeeb tshaj yog nyob rau hauv high-speed aluminium foil dov mills. Lub thickness tswj txoj kev thaum lub sij hawm txhuas ntawv yob yob muaj xws li dov quab yuam tswj, nro tswj, dov ceev tswj, nro / ceev, ceev / nro tswj.
