Problems solved by technology

[0008] For the existing rolling metal composite plate process, when welding the blank, holes are directly opened at the composite joint of the clad plate, and the interface joint is easily oxidized, which affects the quality of the clad plate bond, resulting in a decrease in the bond strength of the clad plate; The equipment required for vacuuming the welded steel pipe is expensive and the process is complicated. The invention provides a method for preventing the interface oxidation of the rolled metal clad plate, that is, opening a vent hole at the interface compound before heating and rolling, and sealing Plugging the vent holes can avoid the problem that the interfacial bond rate decreases due to thermal expansion of the air between the composite interfaces during the heating and rolling process of the clad plate, thereby reducing the bond strength of the clad plate interface.

Embodiment 1

[0046] A method for rolling a stainless steel clad plate, comprising the steps of:

[0047](1) Raw material preparation: 316L stainless steel plate 1 and Q345R carbon steel plate 2 blanks of suitable size are cut from large-sized steel plates by wire cutting. Among them, the size specification of cut 316L stainless steel 1 is 200mm×100mm×5mm, and the size specification of Q345R carbon steel 4 is 200mm×100mm×25mm.

[0048] (2) Surface treatment: before welding the composite billet, it is necessary to treat the surface of the composite blank to increase the bonding rate of the composite surface. First, sand the surface with sandpaper to remove the rust layer and oxide layer on the surface; then repeatedly scrub the composite surface with acetone and alcohol to remove the organic matter and dirt on the surface, and quickly dry it with a hair dryer.

[0049] (3) Blank assembly and welding: In order to make the composite board have better welding quality, it is also necessary to p...

Abstract

The invention discloses a method for preventing interface oxidation of a rolled metal composite plate, and belongs to the technical field of metal composite plate rolling. According to the method, toprevent interface oxidation of the rolled metal composite plate, an exhaust hole is formed in the interface composite position before heating and rolling are carried out, then a sealing plug is used for plugging the exhaust hole, so that the problem that the interface bonding strength of the composite plate is reduced due to the decline of the interface bonding rate caused by the fact that air between composite interfaces is heated and expanded in the heating and rolling process of the composite plate; and the method has the advantages of being simple in structure, reasonable in design and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of metal composite plate rolling, and in particular relates to a method for preventing interface oxidation of a rolled metal composite plate. Background technique [0002] Metal composite panels are a type of metal matrix composite material obtained by forming a firm metallurgical bond at the interface after two or more layers of metal materials undergo some specific processing techniques. Compared with a single metal, metal composite panels not only have the advantages of their respective components, but also can obtain physical, chemical and mechanical properties that single-layer metal materials do not have, so that metal composite panels have high comprehensive mechanical properties. [0003] At present, the main production methods of metal clad plates include explosive clad plate, diffusion clad method, brazing method and rolling clad method, among which the roll clad method is widely used. The rolling...
