Embodiment Construction

[0026] 1) Up-leading copper rod: the high-purity cathodic electrolytic copper with no defects such as "copper beans" and acid marks on the surface is used as the raw material to cut off the lugs. After preheating and drying, it is melted in the melting device (the melting device includes a melting furnace, Static furnace, casting furnace), the temperature of the melting furnace is 1160°C, the copper liquid in the melting furnace is covered with charcoal, the particle size of the charcoal is 40mm, and the covering thickness is 125mm to ensure the reducing atmosphere of the melting furnace; the copper melted by the melting furnace The liquid flows into the static furnace through the flow channel. The temperature of the static furnace is 1160°C. The copper liquid in the static furnace is covered with charcoal. The particle size of the charcoal is 35mm, and the covering thickness is 120mm. The content is 0.005~0.05%; each component with a rare earth content of 0.01~0.05% is require...

Abstract

The invention relates to a silver-copper strip material and a production process thereof. The silver-copper strip material comprises chemical components in percentage by mass as follows: the total amount of copper and silver is larger than or equal to 99.95%, and the silver content is 0.04-0.15%; the oxygen content is smaller than or equal to 0.0005%; the tin content is 0.005-0.05%; the rare earth content is 0.01-0.05%; the sum of other impurities is smaller than or equal to 0.01%; and the sum of all the components is 100%. The production process comprises steps as follows: 1) fusion casting; 2) continuous extrusion; 3) cold rolling; 4) annealing; 5) cold rolling; 6) slitting and 7) packaging for storage. The silver-copper strip material and the production process have the technical advantages as follows: the material composition is reasonable; with the adoption of a novel fusion casting furnace and an online degassing device, performance of high strength, high conductivity, high softening temperatures of the silver-copper strip material is guaranteed, and performance requirements of fields such as a nuclear fusion device, a commutator, a contact switch, and the like are met; and the production process is short in procedure, efficient and energy-saving, energy consumption can be saved by more than 20% while compared with a conventional production process, and the yield is larger than 75%.

Description

technical field [0001] The invention relates to a technology in the field of nonferrous metal processing, in particular to a silver-copper strip material and a processing method thereof. Background technique [0002] As a high-strength and high-conductivity copper alloy, silver-copper strip material is widely used in commutators, contact switches, nuclear fusion equipment, etc. At present, the production process of silver-copper strip materials is batching-melting-casting-sawing-milling-face-milling-heating-hot-rolling-cold-rolling-sawing-packaging. The production process mainly has the disadvantages of long process flow, high energy consumption and high production cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a silver-copper strip material and its processing method, which can provide key materials such as commutators, contact switches, and nuclear fusion equipment. At the same time, the method has the a...
