Problems solved by technology

[0002] Most of the PS plate bases produced according to the original domestic manufacturing process have problems such as obvious surface stripes or insufficient tensile strength, which cannot meet the requirements for surface quality and baking strength of PS plate bases for high-end printing at the same time. Therefore, CTP or high-end color printing Most of the PS plate bases for high-end printing are imported from abroad, and there is still a big gap in China about how to improve the manufacturing process to improve the quality of PS plate bases.

specific Embodiment approach 1

[0012] Specific embodiment one: the manufacturing process of this high-grade printing PS plate base, it carries out according to the following process steps:

[0013] First: casting alloy ingots with 1060, 1070, 1050 or 1052 alloys as raw materials, and hot rolling to 2.0~7.0mm;

[0014] Second: the first cold rolling of the hot-rolled billet to 2.0~4.0mm, and more than 30% of the cold working volume is completed;

[0015] Third: complete annealing at a temperature of 300~450°C for 12~20h;

[0016] Fourth: the second cold rolling to 0.8~1.0mm, the third cold rolling to 0.4~0.5mm;

[0017] Fifth: The last cold rolling to 0.27mm, the finished product is obtained after stretching, bending, straightening and packaging.

specific Embodiment approach 2

[0018] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the alloy ingot is hot-rolled to 5.5mm, cold-rolled to 2.5mm for the first time, cold-rolled to 0.85mm for the second time, and cold-rolled for the third time. Rolled to 0.45mm.

specific Embodiment approach 3

[0019] Embodiment 3: This embodiment is different from Embodiment 1 in that the complete annealing temperature is 420°C.

Abstract

The invention relates to a method for producing PS version base of print, wherein it comprises: 1, using 1060, 1070, 1050, or 1052 alloy as material to cast alloy cast ingot, thermally rolling it into 2.0-7.0mm; 2, first cold rolling into 2.0-4.0mm, completing 30% of cold process; 3, at 300-450Deg. C, completely annealing for 12-20h; 4, secondly cold rolling to 0.8-1.0mm, and thirdly cold rolling to 0.4-0.5mm; 5, at last, cold rolling to 0.27mm, bending, packing, obtaining the final product. The invention can significantly eliminate the surface pattern, improve the surface quality, and improve the strength.

Description

technical field [0001] The invention relates to a manufacturing process of a PS plate base for high-grade printing. Background technique [0002] Most of the PS plate bases produced according to the original domestic manufacturing process have problems such as obvious surface stripes or insufficient tensile strength, which cannot meet the requirements for surface quality and baking strength of PS plate bases for high-end printing at the same time. Therefore, CTP or high-end color printing Most of the PS plate bases for high-end printing are imported from abroad, and there is still a big gap in China about how to improve the manufacturing process to improve the quality of PS plate bases. Contents of the invention [0003] The purpose of the present invention is to provide a high-grade printing PS plate base manufacturing process, the manufacturing process can not only significantly eliminate the surface stripes of the PS plate base, improve the surface quality, but also imp...
