Pressure core-filling continuous casting equipment and process for double-metal-bag long carbon fiber composite material

Abstract

The invention provides pressure core-filling continuous casting equipment and a process for a double-metal-bag long carbon fiber composite material. The continuous casting equipment is composed of an inner-layer metal plug rod, a carbon fiber guide pipe, an inner-layer metal thermodetector, an inner-layer metal pressurizing cover, an outer-layer metal thermodetector, a core filling pipe, an outer-layer metal pipe thermodetector, a composite interface pressurizing device, a heat-insulating and water-stopping plate, a secondary cooling device, a drawing roller, a finishing roller, an inner-layer metal liquid pressurizing pipe, an inner-layer metal temperature control furnace, an outer-layer metal liquid pressurizing pipe, an outer-layer metal pressurizing cover, an outer-layer metal liquid temperature control furnace, an outer-layer metal liquid temperature control crystallizer, a composite interface pressurizing device, a heating element and a temperature control element. Inner-layer metal is smelted and insulated in the inner-layer metal temperature control furnace and is filled into a condensed outer-layer metal pipe inner hole and one bundle of long carbon fibers through the core filling pipe, so as to be fused and condensed with the inner-layer metal and the carbon fibers to form a composite material. The speed of core-filling and continuous casting is controlled by the drawing roller and an outer-layer metal pipe casting blank is pressurized to be ejected out from the outer-layer metal liquid temperature control crystallizer.

Description

technical field

[0001] The invention belongs to the field of metal materials, and relates to pressure-filled core continuous casting equipment and technology of bimetal-clad long carbon fiber composite material. Background technique

[0002] Copper-clad aluminum and silver-clad aluminum composite conductors are bimetallic composite conductors with a copper (or silver) layer concentrically coated on the inner metal core, mainly used for high-frequency information transmission, such as the inner conductor of coaxial cables for mobile communication signals , and certain military uses. The frequency of mobile communication signals is very high, generally 50~800MHz. According to the principle of "skin effect", high-frequency electromagnetic waves are only concentrated on the thin copper (silver) layer on the surface of the conductor for transmission, so the copper (silver) package Layer metal composite conductors have exactly the same transmission properties as copper (silver) c...
