This application discloses a friction energy dissipation unit device, relating to the field of slope protection net technology. It includes a first plate, a second plate, a steel wire rope, a sleeve, and a core ring. The first plate is located below the second plate and the two are connected. The second plate has an irregularly shaped surface and symmetrical first and second energy dissipation channels. The steel wire rope has energy dissipation channels at both ends, forming a U-shaped structure. The sleeve is fitted with the U-shaped structure to form a clamping structure, which engages with the arc-shaped groove of the core ring. Under external force, the steel wire rope slides relative to the energy dissipation channels to achieve frictional energy dissipation. Some embodiments increase the constraint area through S-shaped / spiral channels or achieve secondary energy dissipation through sliding connections between the plates. The device adopts a frictional energy dissipation mode, has no irreversible deformation, is reusable, and has a detachable structure for easy maintenance. It is suitable for external force energy dissipation scenarios such as earthquakes and rockfall impacts in slope protection net systems.

The application discloses a method for regulating material reaction rate to improve finished product rate of aluminum-tantalum intermediate alloy, and relates to the technical field of intermediate alloy materials. The specific steps comprise the following steps: mixing large-granularity tantalum pentoxide, aluminum particles and potassium chlorate to obtain first-grade material; mixing medium-granularity tantalum pentoxide, aluminum particles and potassium chlorate to obtain second-grade material; mixing small-granularity tantalum pentoxide, aluminum particles and potassium chlorate to obtain third-grade material; sequentially adding the third-grade material, the second-grade material and the first-grade material into a reaction crucible, and insulating the materials by using porous aluminum foil, then performing aluminothermic reaction, and then performing gradient cooling to obtain aluminum-tantalum alloy without loose material. The reaction rate of the materials in the crucible gradually increases from top to bottom, the problems of poor slag-ingot separation and insufficient feeding caused by long formation of alloy liquid at the end of solidification and slow backflow are solved, the formation time of the alloy liquid in the later period is shortened, the backflow feeding is accelerated, the loose and stratification defects of the aluminum-tantalum alloy ingot are reduced, and the finished product rate is improved by more than 6%.
