Method for manufacturing aluminum plate for printing-based PS plate

Patent name: Printing method for the production of PS-based aluminum plates Patent applicant Dongbei Light Alloy Co., Ltd. Main applicant Address: 15060 Inventor of Xinjiang Street, Pingfang District, Harbin, Heilongjiang Province Zhong Li; Xu Tao; Tang Mingjun; Li Yahong; Tao Zhimin; Application (Patent) No. 200510010005.3 Date of Application 2005.05.20 Approval Date Approval Notice No. 1693992 Validation announcement date 2005.11.09 Instruction CD-ROM D0545 Main classification number G03F7/09 Classification No. G03F7/09; G03F7/004; B41N3/03 Original The method for manufacturing a base plate for a PS plate based on priority number abstract printing for an application number relates to a production process of an aluminum alloy aluminum plate. It solves the problems of poor organization, poor surface quality, poor plate shape, and uneven thickness of existing aluminum plates. The method comprises the following steps: a. mixing the above-mentioned alloy components in a ratio by weight of Al:98, Si:<1.0, Fe:0.3-1.0, Cu:0.03, Zn:0.03, Mg:0.03, Ti:0.05. After the temperature of 720 ~ 800 °C under the conditions of smelting; b. in the temperature of 690 ~ 750 °C under the conditions of casting alloy ingots; c. In the temperature of 500 ~ 610 °C under the conditions of ingot annealing uniform; d. In the temperature of 400 ~ 540 °C temperature hot rolling; e. From 9.0mm cold-rolled to 0.7mm; f. In the temperature of 300 °C ~ 500 °C under the conditions of intermediate annealing 11h, heat 1h after cold rolling 0.15mm. The invention has the advantages of light weight, high strength, good water resistance, good hydrophilicity, good stability, and easy surface treatment. Sovereignty Item 1, a method for manufacturing an aluminum plate for printing-based PS plates, characterized in that its method steps are: a. Parts by weight: Al: 98, Si: <1.0, Fe: 0.3-1.0, Cu: 0.03, Zn: 0.03, Mg: 0.03, Ti: 0.05 The above alloy components are mixed and melted at a smelting temperature of 720-800°C; b, then cast into an alloy cast at a casting temperature of 690-750°C. Ingot; c, alloy ingot at a temperature of 500 ~ 610 °C under the conditions of uniform ingot annealing; d, and then at a temperature of 400 ~ 540 °C temperature hot-rolled; e, hot-rolled blank by 9.0mm cold Rolled to 0.7mm; f, in the temperature of 300 °C ~ 500 °C under the conditions of intermediate annealing 11h, heat 1h and then cold-rolled to 0.15mm, after stretching, completely straightened, cut to obtain the finished product.
