specific Embodiment approach 1

[0004] Specific embodiment 1: The steps of the method are: a. According to the ratio of parts 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 mixing the above alloy components, smelting at a melting temperature of 720-800°C; b, then casting an alloy ingot at a casting temperature of 690-750°C; c, casting an alloy ingot at a temperature of 500-610°C Under the condition of ℃, the ingot is homogenized and annealed; d, and then hot-rolled at a temperature of 400-540 ℃; e, the hot-rolled billet is cold-rolled from 9.0mm to 0.7mm; f, at a temperature of 300-540 ℃; Intermediate annealing at 500°C for 11 hours, heat preservation for 1 hour, and then cold rolling to 0.15 mm. After stretching, complete straightening, and shearing, the finished product is obtained. The finished product is obtained after being cut by a 1300 slitting machine.

specific Embodiment approach 2

[0005] Embodiment 2: In this embodiment, on the basis of Embodiment 1, a refining agent is added to the alloy composition, and the amount added is 0.1-1% of the total weight of the alloy. The refiner is aluminum titanium boron refiner.

specific Embodiment approach 3

[0006] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 is that the weight ratio of each alloy component in the aluminum plate is Al: 98, Si: 0.8, Fe: 0.4, Cu: 0.03, Zn: 0.03, Mg: 0.03, Ti: 0.05.

Abstract

A manufacturing method of aluminum board used for the PS plate aluminum board used for printing. The steps of the method are: a. according to the weight proportions of Al: 98, Si: < 1.0, Fe: 0.3 - 1.0, Cu: 0.03, Zn: 0.03, Mg: 0.03, Ti: 0.05, mix the said alloy components and smelt them in the temperature condition of 720 - 800 Deg. C; b. found them into alloy cast ingot in the temperature condition of 690 - 750 Deg. C; c. make the cast ingot equably anneal in the temperature condition of 500 - 610 Deg. C; d. have hot roll in the temperature condition of 400 - 540 Deg. C; e. cold roll them from 9.0 mm to 0.7 mm; f. have 11 hours' middle anneal, 1 hour's heat preservation, then cold roll them to 0.15 mm. The advantages are light weight, high intensity, good water-proof performance, good hydrophilic performance and easy to have surface process.

Description

Technical field: [0001] The invention relates to a production process of an aluminum alloy aluminum plate, in particular to a production method of an aluminum plate for a PS plate base for printing. Background technique: [0002] The original PS plate base aluminum plate for printing has the disadvantages of poor surface quality, low dimensional accuracy, poor shape quality, high reject rate, and improper control of Fe and Si content, and the previous production process will make the aluminum alloy ingot microstructure Inhomogeneity, coarse grains, segregation, dendrites and other abnormal structures, in the subsequent use process, will cause problems such as black bars, bright spots on the surface, poor shape quality, and unqualified same plate difference. Invention content: [0003] The object of the present invention is to provide a method for manufacturing an aluminum plate used as a PS plate base for printing, which solves the problems of poor structure, poor surface ...
