Abstract

The invention provides a device for rolling a silver magnesium nickel alloy narrow band. The device comprises a paying-off wheel, rollers and a take-up wheel. A roller entrance guide wheel is arranged at inlets of the rollers. A straightening mechanism is arranged at outlets of the rollers. Spray guns utilizing compressed air to purge the surfaces of the rollers are arranged on the portions, above and below the inlets, of the rollers respectively. The invention further provides a method for utilizing the device to roll the silver magnesium nickel alloy narrow band. The method includes the following steps of (1) selecting a silver magnesium nickel alloy wire, and determining rolling passes; (2) carrying out first pass rolling to obtain a semi-finished product narrow band; and (3) carrying out second pass rolling to obtain the silver magnesium nickel alloy narrow band. The problem that the requirement for technology of the product is high can be effectively solved, and the narrow band product meeting the quality requirement can be obtained. The device has the beneficial effects of being simple in machining process, high in production efficiency, simple in structure, high in use reliability, high in repeated operability and the like.

Description

technical field [0001] The invention belongs to the technical field of alloy material processing, and in particular relates to a device and method for rolling a silver-magnesium-nickel alloy narrow strip. Background technique [0002] Silver-magnesium-nickel alloy is a ternary alloy composed of silver as the base and adding a small amount of magnesium and nickel, which belongs to the internal oxidation strengthening material. When the silver-magnesium-nickel alloy is heated in air, oxygen-enriched or oxygen, the magnesium atoms originally present in the solid solution are preferentially oxidized to form submicroscopic MgO dispersion-strengthened particles, which rapidly increase the strength, hardness and elastic properties of the alloy, and maintain Good electrical conductivity, thermal conductivity and electrical contact performance, low creep rate at high temperature, good anti-relaxation performance. Silver-magnesium-nickel alloy combines the properties of electrical co...
