Example Embodiment

[0039] Example 1:

[0040] Prepared as figure 1 (A) The contact line shown without grooves.

[0041] A production equipment for a new type of large-length, large-diameter, high-strength, high-conductivity composite wire rod, including an internal mold tube 7, an external mold tube 9, a circulating cooling system 2, and a coil 1. The diameter of the external mold tube 9 is larger than that of the internal mold tube 7. The inner mold tube 7 is sleeved into the outer mold tube 9, and the copper liquid 4 is injected between the inner mold tube 7 and the wall of the outer mold tube 9. When the copper liquid 4 passes through the circulating cooling system 2, the upper part is the copper liquid 4, and the lower part Partly solidified into a copper tube 15, the upper inlet of the inner mold tube 7 is higher than the inlet of the outer mold tube 9, and the outlet of the inner mold tube 7 is located in the middle of the solidified copper tube 15. The inner mold tube 7 has the center of the ...

Abstract

The invention provides production equipment of a large-length, large-diameter, high-strength and high-conductivity novel composite wire and a process thereof. The production equipment is characterizedby comprising an internal mold pipe, an external mold pipe, a circulating cooling system and a coil, wherein the diameter of the external mold pipe is larger than the diameter of the internal mold pipe; the internal mold pipe is sleeved in the external mold pipe; copper liquid is injected between pipe walls of the internal mold pipe and the external mold pipe; when the copper liquid passes through the circulating cooling system, the upper part is the copper liquid, and the lower part is solidified as a copper pipe; an upper inlet of the internal mold pipe is higher than an inlet of the external mold pipe; and an outlet of the internal mold pipe is positioned at the middle part of the solidified copper pipe. Through self-weight of vertical mixed liquid and control of the solidification time and speed of the mixed liquid, the thickness of a copper and steel composite layer can be adjusted, the firmness, the bonding degree and the integrity of the composite wire are improved, and meanwhile, the tensile strength and the electric conductivity are improved.

Description

technical field [0001] The invention relates to a production equipment and technology of a new composite wire with large length, large diameter, high strength and high conductivity. Background technique [0002] With the development of electronic information technology, the requirements for the comprehensive performance of copper alloy conductive materials are getting higher and higher. It is required to maintain high electrical conductivity and thermal conductivity while maintaining high strength (hardness), toughness, and wear resistance. Sex, cold resistance, non-ferromagnetic and other characteristics. These excellent properties make copper alloys gradually become important metal materials used in high-tech fields such as electric power, information, transportation, energy, light industry and aerospace. In many occasions, it is rarely used in the form of pure copper. This is because the strength of pure copper is low (230-300 MPa). Although it can reach 400 MPa after co...
