Cathode Drum with 3.6 meters The biggest side in the word for Copper Foil Equipment
Technical Point:
The cathode drum plays a pivotal role in the production of electrolytic copper foil, with the crystal structure on the drum's surface directly influencing the crystalline state of the copper foil. During this process, if the titanium layer on the cathode drum exhibits high surface roughness and grain size, it results in a finer grain size of the copper foil, enhancing its ultra-thin toughness and other desirable properties.
Production and Processing Method:
The manufacturing process of the titanium layer on the cathode drum primarily involves welding, spinning, and other techniques. The innovative "ring rolling" technology, which combines forging and rolling, effectively meets the microstructural morphology and mechanical property requirements. This technology significantly improves the production quality of the titanium layer, thereby enhancing the overall quality of the deposited copper foil. It ensures the fineness and uniformity of the microstructure on the titanium surface, leading to consistent grain size. Analysis and comparison of relevant research indicate that this technology is crucial for the direct production of titanium rolls. It provides valuable insights for the future application of larger-scale "large-diameter, thin-walled, high-cylinder" spinning titanium rolls, supporting the rapid development of industrial production of cathode drums.
Our Cathode Drum total have 3 layers, first layer Stainless steel, second layer copper, the third layer GR1 pure titanium. The third layer titanium ring is seamless, The last layer is a seamless titanium ring. The cathode drum with a seamless ring produces higher quality copper foil.
