Embodiment 1

[0043] Adopt the present invention to produce 4005 / 3003 / 4005 three-layer aluminum alloy composite board. This three-layer aluminum alloy composite board has the advantages of good welding performance of 4005 aluminum alloy and good corrosion resistance of 3003 aluminum alloy. It is often used in the manufacture of automobiles, electronics, Heat exchangers for electrical appliances, etc., as follows:

[0044] Step 1: Clean the surface of the core layer 3003 aluminum alloy plate to remove oil stains and scale on the surface;

[0045] Step 2: Pass the core layer 3003 aluminum alloy plate through the rectangular channel on the preheating device and the rectangular channel on the crystallizer in turn, and finally reach the gap between the two rolls, and then turn on the power of the preheating device to heat the core layer The metal plate is preheated, and the preheating temperature is 200°C;

[0046] Step 3: Heat and melt the 4005 aluminum alloy liquid in a resistance melting fur...

Abstract

A short-process rolling forming device and method for a three-layer metal composite plate, comprising a frame, two rollers installed horizontally side by side on the frame, a crystallizer installed on the two rollers, and two rollers installed on the crystallizer A tundish and a preheating device installed in the middle of the crystallizer and between the two tundishes, the center of the crystallizer and the center of the preheating device are provided with a rectangular channel for the core metal plate to pass through. The present invention has adopted the structure that two crystallization cavities are arranged between the crystallizer and the two rolls and a rectangular passage for the core layer metal plate to pass is arranged at the center of the crystallizer. In the two crystallization cavities, the The two cladding layer metal liquids are continuously cooled and stirred into a semi-solid slurry, and then they are directly compounded and rolled with the core metal plate to form a three-layer metal composite plate. The board quality is good and so on.

Description

technical field [0001] The invention belongs to the technical field of metal composite plate preparation, and in particular relates to a short-flow rolling forming device and method for a three-layer metal composite plate. Background technique [0002] The three-layer metal composite panel is a metal composite panel with a sandwich structure formed by covering the upper and lower sides of the core metal plate with two other layers of metal. The core metal and the cladding metal are combined by interface metallurgy. The core metal and the cladding metal on the upper and lower sides are different metals, and the cladding metal on the upper and lower sides can be the same metal. It can also be different metals. Therefore, the three-layer metal composite board combines the properties of two or three metals. It is a multi-functional and multi-purpose metal board that can be widely used in automobiles, electronic appliances, metallurgy, chemical industry aerospace and other field...
