Embodiment 1

[0012] Embodiment 1: the silver plate is rolled to a thickness of 12 mm, a groove of a certain size is finished with a milling machine on both sides of the silver plate, and a boss of a certain size is finished with a milling machine at one side of a copper plate with a thickness of 12 mm, The grooves and bosses are interference-fitted into a copper / silver / copper composite billet. The composite billet is heated and kept at 600°C for 10 minutes under the protection of argon, and is hot-rolled on a φ350 hot rolling mill to a thickness of 1.80mm, and then rolled on a cold rolling mill. Cold rolled to 0.20mm, annealed at 450°C under argon protection for 30 minutes, finish rolled to 0.10mm, slit to 80mm wide, and finished products after cleaning.

Embodiment 2

[0013] Embodiment 2: Extrude the silver ingot into a double-sided groove-shaped silver profile, and then cut it into a double-sided groove-shaped silver composite billet; extrude the copper ingot into a single-side protruding copper profile, and then cut it into a single-side protruding copper profile. Composite billet: after the interference fit of the copper / silver / copper composite billet, under the protection of argon, it is heated and kept at 600°C for 10 minutes, hot rolled on a φ350 hot rolling mill to a thickness of 1.80mm, and then cold rolled on a cold rolling mill to 0.20mm, annealed at 450°C for 30 minutes under argon protection, finish rolling to 0.10mm, slitting to 80mm width, and finished products after cleaning.

Embodiment 3

[0014] Embodiment three: the silver plate is rolled to be 12mm thickness, go out the groove of certain size with mould, die-pressing the groove of certain size at two sides of silver plate, make double-sided groove shape silver composite billet; A boss of a certain size is molded on the side to make a single-side protruding copper composite billet. After interference fitting the copper / silver / copper composite billet, it is heated and kept at 700°C for 10 minutes under the protection of argon, and hot rolled at φ350 Hot rolling on the machine to a thickness of 1.80mm, then cold rolling to 0.20mm on a cold rolling mill, annealing at 450°C under argon protection for 30 minutes, finish rolling to 0.10mm, slitting to a width of 80mm, and cleaning to become finished products.

Abstract

A preparation method of bilateral surface mosaictype hot rolling compound silver copper strip material comprises: rolling silver ingot into a plate-shaped blank with a certain thickness, cutting the blank to form silver blank in sections, and processing the silver blank into bilateral groove-shape compound silver preform in machine tooling or deepdrawn manner; processing the copper blank into unilateral protruding shape compound copper preform in machine tooling or deepdrawn manner; hot rolling compositing the compound copper preform / compound silver preform / compound copper preform lateral under argon gas protection after interference fit, with heating temperature of 500-900DEG C., soaking time of 10 minutes-100 minutes, and deflection of 40%-90%, to change mechanical interference fit of the compound copper preform / compound silver preform / compound copper preform into crystal combination between mosaic atoms; and cold rolling, annealing and finishing rolling the strip material to obtain the product which has more strong compound layer with higher bonding strength compared with prior technology.

Description

Technical field: [0001] The invention relates to a preparation method of a composite strip, in particular to a preparation method of a double-sided mosaic hot-rolled composite silver-copper strip. Background technique: [0002] At present, pure silver strips are widely used. For example, pure silver strips are used in the melt of some fuses. Since silver is a precious metal, its price is high and rising, resulting in high and rising costs of pure silver strips. conducive to its promotion and application. [0003] A Chinese patent once disclosed a "copper / silver / copper double-sided composite plate strip" (CN2718768Y, announced on August 17, 2005), which included two metal strips of silver and copper, wherein the silver strip was on the surface of the board. In the middle of the silver bar, both sides of the silver bar are copper bars, and the silver bar and the sides of the copper bars on both sides are metallurgically bonded with high strength. However, its multi-layer fir...
