1.Residual Stress in Capacitors Manufacturing Residual stress refers to the secondary stress remaining in the deformed body after the external force is removed during the XUANSN capacitors manufacturing process. Residual stress can be caused by deformation, uneven heating and cooling, and uneven microstructure transformation. Residual stress, corresponding to secondary stress, is also classified into first-type, second-type, [...]
Plastic deformation of metal is uneven deformation. This unevenness will have a significant impact on the structural integrity of the material and the capacitor performance. An object is divided into many small grids, called coordinate grids (see Figure 1). If the height before deformation is H and the width is B, the height of each grid [...]
Modern metal rolling is performed on rolling mills equipped with automatic thickness and shape control systems (see Figure 1). Flat castings or billets are fed between two counter-rotating rolls. The friction exerted by the rotating rolls typically forces the rolled material into the gap between the rolls. Once in the gap, the rolled material deforms under [...]
In strip casting and rolling production, equipment failures often directly impact product quality and production efficiency, a critical issue for XUANSN, which prioritizes high quality. Proper equipment maintenance and management is not only fundamental to ensuring smooth production, but also essential for XUANSN to achieve high-quality production. This issue is particularly prominent in the production process [...]
(1) Coarse Grains. Coarse grains often manifest as wheat-ear crystal structure. As mentioned above, due to the lack of active crystal nuclei in electrolytic aluminum liquid and superheated aluminum melt, the energy of homogeneous nucleation is higher than the energy of nucleation on the surface of the casting roller sleeve. Therefore, during the casting process, when [...]
