Abstract

The invention discloses a method for manufacturing a metal composite plate, and belongs to the technical field of metal composite plate manufacturing technology. The method comprises the following steps that firstly, the rusty layer and the oxide layer of multiple layer metal and parent metal are removed, the corners at the two ends and the middle of the metal layer placed on the upper face in the process of heating are respectively drilled, and each position of the corners at the two ends and the middle of the metal layer is provided with a vent hole with the diameter ranging from 4mm to 8mm; secondly, the multiple layer metal and the parent metal are stacked, and the periphery of the contact face is welded and sealed; thirdly, the air inside the contact face space is completely exhausted by injecting argon through the vent hole in one end, and the vent holes in the two ends are sealed; fourthly, the metal composite plate is placed inside a heating furnace to be heated according to the production requirements for the composite layer metal; fifthly, the metal composite plate is rolled on a rolling mill; sixthly, if the multiple layer metal needs to be later processed in a heat mode, the composite plate is processed in the heat mode according to the demands. By means of the method, the oxidation of the contact face of the metal composite plate can be reduced, the shearing strength of the contact face of the metal composite plate is improved, vacuumizing is not needed, operation is easy, and cost is low.

Description

technical field [0001] The invention relates to a method for manufacturing a metal composite board, belonging to the technical field of metal composite board manufacturing technology. Background technique [0002] The metal composite panel is made of multiple layers of metals with different components and different properties. It can have both the properties of the clad metal and the base metal, and can also use the cheap base layer metal to replace the expensive clad layer metal to reduce costs. Therefore, there is a huge demand for metal clad panels in the market, including: stainless steel-steel clad panels, wear-resistant steel-steel clad panels, titanium-steel clad panels, etc. [0003] At present, the preparation methods of metal clad plates mainly include brazing cladding method, explosive cladding method and rolling cladding method. [0004] The brazing composite method is a method in which the solder is placed between the cladding metal and the base metal, and pres...
