Embodiment 1

[0031] The production process of a phosphor copper strip for electrical engineering in the first embodiment includes the following steps:

[0032] Upward continuous casting-continuous extrusion-cold rolling-annealing-finishing rolling-cleaning passivation-slitting

[0033] The specific steps are:

[0034] 1. Upward continuous casting

[0035] Using high-purity copper cathode, 20% phosphorous copper alloy and 5% copper tellurium alloy as raw materials, the high-purity copper cathode, 20% phosphorous copper alloy, and 5% copper tellurium alloy are preheated and dried in the melting device. For melting, charcoal and graphite flakes are used to cover the copper liquid surface, and a traction unit is used to draw the copper rod. The melting device includes a melting furnace and a holding furnace.

[0036] Further settings are as follows: the temperature of the crystallizer outlet water is controlled at 30℃~34℃, the temperature of the melting furnace is 1180℃~1185℃, and the drying charcoal ...

Abstract

The invention relates to a production technique for a phosphor copper strip for electrical purposes. The production technique comprises the first step of introduction of a copper bar onto a tractor unit with high-purity cathode copper as a raw material, the second step of continuous extrusion of a copper strip blank, the third step of cold rolling, the fourth step of annealing, the fifth step of finish rolling, the sixth step of cleaning and passivation, and the seventh step of splitting. The produced phosphor copper strip for electrical purposes has high purity, low oxygen content, high electric conduction and high surface quality. The technique is short in process, high in efficiency and capable of saving energy.

Description

Technical field [0001] The invention relates to the technical field of non-ferrous metal processing, in particular to a production process of a phosphor copper strip for electrical engineering. Background technique [0002] Copper has a wide range of applications in the electrical field, and can be used as conductive parts, heat dissipation parts, etc. At present, pure copper is widely used in electrical engineering. Although pure copper has good electrical conductivity, its strength is limited. At the same time, pure copper is prone to discharge during the contact process of electrical devices. [0003] Microalloying is the focus and hotspot of copper research and development. By adding a small amount of other elements to pure copper, certain properties of copper can be improved to meet the increasing application of copper. Adding other trace elements to pure copper will have a certain impact on the electrical conductivity of copper materials. However, for some special applicatio...
