Abstract

The invention discloses an improved CTP plate base aluminum alloy strip based on a 1052# aluminum alloy. The improved CTP plate base aluminum alloy strip is manufactured through the procedures of melting, refining, cast rolling, finish rolling, stretch bending and straightening. To save the production time and improve the production efficacy, a 1052# aluminum alloy strip is directly selected as araw material, the excellent physical and mechanical performance is reserved, meanwhile, an Al-Ti-B wire and a titanium-magnesium alloy strip are selected in a grain refining agent, the integral feeding amount of the titanium element is increased, and the grain refining degree is improved; due to the mixed magnesium element, the electrolysis quality is better improved, a sand mesh layer can be better finely and evenly improved, the sand mesh value Ra is greatly improved, and the CTP plate base quality requirement is completely met; and through the improvement on a runner, the feeding frequencyof aluminum molten liquid is improved, and rolling efficiency and quality improving is ensured as well. As a whole, the product CTP plate base aluminum alloy strip completely meets the CTP plate basequality requirement, and meanwhile the beneficial effects of the simple technology and the high production efficiency are achieved.

Description

technical field [0001] The invention relates to the field of aluminum alloy strip production, in particular to an improved CTP plate-based aluminum alloy strip based on No. 1052 aluminum alloy. Background technique [0002] CTP plate has the advantages of high printing quality, no environmental pollution, remote plate transfer and on-demand printing, etc., so the application of CTP plate has been developed rapidly, and it has become a trend to replace the traditional PS plate. The aluminum alloy strip has internal defects such as poor surface quality, insufficient flatness, and coarse structure, resulting in electrolytic corrosion performance that cannot meet the requirements of high-quality printing. [0003] The physical and mechanical properties of 1052 aluminum alloy are outstanding, which fully meets the elements of the CTP plate base. Improvements on this basis can significantly improve the quality of the obtained CTP plate base. Contents of the invention [0004] A...
