preparation example Construction

[0027] The preparation process of the composite bimetallic wire base material of the present invention comprises the following steps:

[0028] The aluminum-magnesium alloy rod raw material enters the continuous extruder at normal temperature and is continuously extruded by the continuous extrusion method to obtain the composite bimetallic wire base material, wherein the temperature of the inlet of the extruder cavity is normal temperature, and the control deformation rate is 70%- 95%, the extrusion speed is 110-460kg / h, so that the outlet temperature of the extruder cavity is 380-450℃.

[0029] The raw material of the aluminum-magnesium alloy rod is obtained by the following method: the Φ9.50mm aluminum-magnesium alloy rod obtained by the conventional horizontal continuous casting method is stretched to Φ8.50mm for rounding treatment; and then rinsed with clean water to remove adsorption on the aluminum-magnesium alloy. The sediment on the surface of the rod is completely drie...

Abstract

The invention discloses a preparation process of a composite bimetallic wire substrate. The provided preparation process can bring a material into a continuous extrusion machine under a normal temperature state to realize one-time production of a product with good performance through a continuous extrusion technology. According to the process, an aluminum-magnesium alloy rod raw material is delivered into the continuous extrusion machine under normal temperature for undergoing continuous extrusion through a continuous extrusion method, thus obtaining the composite bimetallic wire substrate. Specifically, the inlet of an extrusion machine cavity is at normal temperature, the deformation rate is controlled at 70%-95%, the extrusion speed is controlled at 110-460kg / h, and the outlet temperature of the extrusion machine cavity is 380-450DEG C. The process provided in the invention delivers the raw material into the continuous extrusion machine under a normal temperature state, adopts the continuous extrusion technology to prepare an aluminum-magnesium alloy rod, and realizes the product production in one time. Due to the employment of a large deformation amount, and the control of the extrusion machine outlet temperature by combining the deformation amount and the extrusion speed, the internal defects of the aluminum-magnesium alloy rod raw material are effectively controlled. The obtained product has good surface quality, and can have improved mechanical properties, electrical properties and the like after coating.

Description

technical field [0001] The invention relates to a preparation process of a composite bimetallic wire base material. Background technique [0002] A large number of communication cables, signal cables and control cables have shielding braids, which are used to prevent electric field interference due to potential difference of conductors and magnetic field interference due to current frequency. The braided wire plays both the role of shielding and bundling, so it is required to have high strength; in order to reduce the leakage rate, sometimes a complex braided pattern is used, and the braided wire is required to have high bending resistance; under non-short-circuit conditions Due to the extremely weak current in the shielded braided wire, the requirements for the conductivity of the material are not high. [0003] The traditional shielded braided wires are mainly pure copper wires and aluminum wires (aluminum alloy wires). Broken wires, and in many occasions, when used with...
