1 capacitor casting dendrite structure During the casting process, crystals always grow in the form of dendrites, which easily form a cellular structure with strong directionality or a more obvious dendrite network structure. This phenomenon is particularly significant in the capacitor casting dendrite structure. When the electromagnetic field is introduced during casting, the cellular structure or dendrite [...]

1 Electromagnetic Casting and Rolling Technology of Capacitor Aluminum Alloy The electromagnetic casting and rolling process includes electromagnetic process parameters and casting and rolling process parameters, mainly including: excitation current, magnetic field strength, magnetic field oscillation frequency, magnetic field oscillation form, magnetic field switching frequency, which is suitable for the forming and organization control of capacitor [...]

Currently, in the casting and rolling production of aluminum and aluminum alloys, in order to obtain uniform and fine equiaxed crystal structure, the most effective way is to use aluminum titanium boron wire for online modification. However, this method has very strict technical requirements for aluminum titanium boron wire, and at the same time, hard phase [...]

1 Preparation of gating system in capacitor foil manufacturing The main function of the casting system is to transport the liquid metal from the static furnace to the feed nozzle. During the transportation process, the aluminum melt is further purified to improve the purity of the melt, maintain a certain and stable pressure of the melt, [...]

1 Casting-Rolling Speed During the continuous casting-rolling process of capacitor foil strip, the crystallization process of the strip is from the surface of the casting roll vertically to the center of the casting-rolling billet along the outlet side to the inlet side. The casting-rolling zone is triangular. As the casting-rolling rolls rotate continuously, the heat is [...]
