Description
Technical field
The present invention relates to a kind of preparation method of composite strip, especially at a kind of preparation method of alternate side direction silver-copper composite strip.
Background technology
Silver/copper composite band is mainly used on the low-tension fuse as the substitution material of pure silver belt.It had both kept the effect of the quick fuse of original silver band, had saved material cost again in a large number, along with the development of industries such as electric power, metallurgy, chemical industry, petrochemical industry forms very big market, will progressively replace a large amount of at present fine silver fusing carrying materials that use.
The preparation method of present silver/copper composite band, disclosed have Chinese patent " copper/silver/copper two sided composite board band " (CN2718768Y, disclosed day on August 17th, 2005) and " a kind of preparation method of double side mosaic type hot-rolling composite silver copper strip " (CN101053874A, open day on October 17th, 2007).Said method makes the less stable of silver bar and the combination of copper bar side because the hot rolling compound tense can produce oxidation; And the working modulus compound owing to hot rolling is bigger, and to having relatively high expectations of capacity of equipment, and the width dimensions of silver bar and copper bar is also wayward.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, provide the multiple layer of a kind of silver of preparing/copper composite band firmly, silver bar and the combination of copper bar side stable higher, to the preparation method of less demanding, the double lateral insert silver-copper composite strip that production cost is low of capacity of equipment.
The objective of the invention is to be achieved through the following technical solutions.
A kind of preparation method of double lateral insert silver-copper composite strip is characterized in that the step of its preparation process comprises:
(1) the strip copper coin is gone up symmetry placed in the middle along its length and leave the strip through hole;
(2) cooperation is inlaid into yellow gold/silver/yellow gold three-layer composite board bar in strip through-hole, forms composite blank;
(3) composite blank after will inlaying is put into vacuum brazing furnace, is incubated 10～30min under 780～850 ℃ of temperature, silver and copper brazing connection;
(4) soldering is connect the back composite blank and carry out cold rolling, annealing, finish rolling to finished product.
The preparation method of a kind of double lateral insert silver-copper composite strip of the present invention is characterized in that described yellow gold/silver/yellow gold three-layer composite board adopts the blast complex method to make by yellow gold plate, silver plate, yellow gold plate.
The preparation method of a kind of double lateral insert silver-copper composite strip of the present invention, it is characterized in that described composite blank through cold rolling, annealing, finish rolling to the cold rolling process conditions of finished product process is: the total working modulus between every twice annealing is 60%～80%, pass reduction is 7%～10%, annealing temperature is 500～600 ℃, and annealing time is 1～2h.
Method of the present invention, having overcome prior art uses the soldering composite methods to produce silver/copper composite band, because scolder is not to fill the interface junction of entering to close defect of bad, yellow gold/silver/yellow gold the three-layer composite board that adopts the blast composite methods to make, solder thickness is 0.1～0.12mm, therefore finished product silver/copper composite band can guarantee that product is attractive in appearance, and resistivity is qualified, can make multiple layer have stability preferably again; Owing to adopt the compound technology of soldering, and in follow-up mill-annealed process, annealing process when adopting rolling technology of little working modulus and middle temperature long, make finished product silver/copper composite band bond strength height, safe and reliable, the silver of preparing/copper composite band, the intensity height of silver bar and the combination of copper bar side, and stability better, replaces pure silver belt to be widely used in the low pressure fastp-acting fuse.When satisfying instructions for use, can save the noble metal fine silver in a large number, thereby reduce production costs greatly.
