Problems solved by technology

Compared with solid-solid composite rolling, this method has the advantages of good forming shape, but in the production process, a large amount of toxic flux is used on the surface and interface, which is difficult to remove, poor thermal stability, strong corrosion, and removal of oxidation. The composite board obtained by this method can meet the general decoration requirements, and it is difficult to withstand the machining of large deformation.

Embodiment 1

[0033] A method for preparing a double-physics-field-assisted single-sided metal layered composite panel, the steps are as follows:

[0034] 1) Clean the surface of pure aluminum plate and pure iron plate with pickling method to remove grease, stains and oxide film, and dry them for later use;

[0035] 2) Preheat the pure aluminum plate and pure iron plate after the above treatment to a temperature of 350°C under atmospheric conditions;

[0036] 3) The above-mentioned preheated pure aluminum plate and pure iron plate are rolled with internal cooling water-cooled rolls, and ultrasonic waves and magnetic fields are continuously applied at the same time, such as figure 1 Shown: Turn on the ultrasonic equipment to continuously apply ultrasonic action. The ultrasonic application device is composed of a transducer, a horn, and a tool head. It can apply transverse and longitudinal ultrasonic waves. The ultrasonic frequency is 3×10 4 Hz, the output amplitude of the tool head is 10μm,...

Embodiment 2

[0038] A method for preparing a double-physics-field-assisted single-sided metal layered composite plate, the steps of which are basically the same as in Example 1, the difference is that the shape of the ultrasonic head of the ultrasonic application device used is different, including roller type, column type, Inverted trumpet type, such as figure 2 shown.

Embodiment 3

[0040] A method for preparing a double-physics-field-assisted single-sided metal layered composite panel, the steps of which are basically the same as in Example 1, except that the aluminum plate is heated and melted, such as image 3 shown.

Abstract

The invention provides a double-physical-field-assisted single-face laminated metal composite plate manufacturing method. The method includes the following steps that the surface of a base metal plate is cleaned through an acid pickling method, grease, stains and oxidation films are removed, and drying is conducted; the base metal plate is preheated under the atmospheric conditions or nitrogen or argon protection condition, the preheating temperature ranges from 150 DEG C to 1700 DEG C; rolling is conducted on the base metal plate or a base metal plate of preset low-melting-point filling materials through an inner-cooling type water cooling roller, meanwhile, ultrasonic waves and magnetic fields are applied continuously till a single-face laminated metal composite plate is manufactured. The double-physical-field-assisted single-face laminated metal composite plate manufacturing method has the advantages that the ultrasonic waves and the magnetic fields are applied, control over the interface reaction and intensifying of mass transfer process are facilitated, a composite welding seam for intensifying intermetallic compound particles is obtained, welding seam grain is refined, residual stress is lowered, the oxidation films are broken effectively, consumption of brazing flux is lowered or avoided, the toxic and side effect on staff and adverse effects on combined interfaces are reduced, energy saving is facilitated, and the environmental pollution is lowered.

Description

technical field [0001] The invention relates to the field of metal composite materials, in particular to a method for preparing a double-physics-field assisted single-sided metal layered composite board. Background technique [0002] The layered metal composite plate is a new type of material that uses different composite connection technologies to achieve a firm combination of two or more base metal plates with different properties. The base metals of each layer still maintain their original characteristics, and their overall performance is superior to that of any single base metal. Therefore, new dissimilar metal composite plates have received widespread attention in recent years. They are widely used in power generation equipment, automobiles, ships, steel road transportation, nuclear energy, It is widely used in machinery, aerospace, petroleum, chemical industry, etc. [0003] The production methods of layered metal composite panels mainly include semi-solid pressure co...
