摘　　要：电解铜箔被称为电子产品信号和电力传输的“神经网络”,阴极辊的质量决定着电解铜箔的品质,阴极辊表面钛筒套焊接成型具有成本较低、生产效率高、不受直径影响等优点。然而,焊接成型工艺制造的阴极辊表面存在一条纵焊缝,调控焊缝区和热影响区组织,达到与基材相近,是焊接阴极辊制造的关键核心技术。以阴极辊用TA1为研究对象,采用退火及喷砂复合处理对焊接成型阴极辊焊缝区和热影响区进行显微组织调控,并采用DMI-3000M型光学显微镜(OM)观察显微组织。结果表明,焊后退火热处理有利于细化焊缝区和热影响区组织,其中650℃退火改善效果最优,可有效细化晶粒,降低焊缝与母材组织的差异。退火后再进行喷砂处理,可进一步细化焊缝区晶粒,获得接近基体的显微组织。最后,采用经复合处理的焊接钛筒套制备了电解铜箔,其表面不存在明显亮带,这说明复合处理焊接钛筒套可有效去除电解铜箔表面因焊缝而引起的亮带。Electrolytic copper foil is one of the important materials for manufacturing copper clad laminate(CCL)and printed circuit board(PCB),it is also known as the"neural network"of electronic product signal and power transmission in the electronic industry.In recent years,due to the rapid development of science and technology in the downstream industry,higher requirements are put forward for the upstream electrolytic copper foil.Not only its demand is getting more and more,but also the quality requirements of copper foil are becoming higher and higher.At present,there are two kinds of methods for producing copper foil,one is calendering,and the other is electrolysis.Electrolytic production of copper foil is an efficient technology developed in recent years,whichhas the following two obvious advantages:highefficiency and low cost.The roll cathode withuniform speed and slow rotation is used to continuously produce electrolytic copper foils withcertain width.Withthe rapid development of China's electrolytic copper foil industry,the demand for cathode roller and the key equipment for producing copper foil are also increasing rapidly year by year.Cathode roller is the core and key part of electrolytic copper foil equipment and its quality determines the grade and quality of copper foil.There are two forming and manufacturing methods of"spinning"and"welding"for the titanium sleeve on the surface of the cathode roll.Althoughthe cathode roll produced by"welding"has many advantages,suchas low production cost,highproduction efficiency and the titanium sleeve is not affected by the diameter,while,the process also has some defects,that is,in the manufacturing process,a relatively obvious longitudinal weld will appear on the surface of the titanium sleeve,and this will cause a spot or bright band on the corresponding position of the copper foil surface in the subsequent production process,whichwill seriously reduce the production efficiency and affect the quality of copper foil.Therefore,the key technology of welding cathode roll i
