The manufacturing method of aluminum sheet for PS plate base for printing, which involves a production process of aluminum alloy aluminum plate. It solves the problems of poor organization, mahinang kalidad ng ibabaw, masamang hugis ng plato at hindi pantay na kapal ng umiiral na mga plato ng aluminyo.
Isang paraan para sa pagmamanupaktura ng aluminium sheet para sa PS plate base para sa pag print, characterized in that it has the method steps of
a, according to the weight ratio Al: 98, Si: <1.0, Paa: 0.3 ~ 1.0, Cu: 0.03, Zn: 0.03, Mg: 0.03, Ti: 0.05 ratio of the above-mentioned alloy components mixed in the melting temperature of 720 ~ 800 ℃ conditions melting;
b, and then cast into alloy ingots at a casting temperature of 690-750 °C;
c, the alloy ingot in the temperature of 500 ~ 610 ℃ to make the ingot homogenization annealing;
d, and then hot-rolled at a temperature of 400 sa 540 °C;
e, hot-rolled blanks from 9.0mm cold-rolled to 0.7mm;
f, intermediate annealing at a temperature of 300 ℃ ~ 500 ℃ for 11h, holding 1h and then cold-rolled to 0.15mm, after stretching, complete straightening, shearing to get the finished product.
