Embodiment 1

[0044] Such as figure 1 Shown: This method is used to prepare stainless steel-carbon steel single-sided composite panels.

[0045] 1. Slab processing: select one carbon steel plate and one stainless steel plate with a size of 1200mm long × 600mm wide. The carbon steel plate is made of Q235 plate with a thickness of 60mm, and the stainless steel plate is made of 304 stainless steel with a thickness of 10mm. Along the length direction, mutually matching rectangular protrusions are processed on one surface of the carbon steel plate and the stainless steel plate respectively, the number of rectangular protrusions on a single metal slab is 4, the rectangular protrusions are continuously distributed, and the height of the rectangular protrusions is It is 4mm and its width is 100mm. After the processing is completed, clean the processing surface to remove all oil stains; stack the processing surfaces (ie composite surfaces) of the two metal slabs relative to each other, so that the r...

Embodiment 2

[0052] Such as figure 2 Shown: This method is used to prepare stainless steel-carbon steel double-sided composite panels.

[0053] 1. Slab processing: Select carbon steel plate and stainless steel plate with a length of 1200mm×width 600mm respectively. The carbon steel plate adopts Q345 plate with a thickness of 60mm and the quantity is 1 piece. The stainless steel plate adopts 304 stainless steel with a thickness of 10mm and the quantity is 2 pieces. Along the length direction, mutually matching rectangular protrusions are processed on two surfaces of the carbon steel plate and one surface of the stainless steel plate respectively. The number of rectangular protrusions on a single metal slab is 5, and the rectangular protrusions are continuously distributed. The height of the protrusion is 3mm, and its width is 80mm. After processing, clean the processing surface to remove all oil stains; stack the slabs in the order of stainless steel plate, carbon steel plate, and stainle...

Embodiment 3

[0060] Such as figure 1 Shown: This method is used to prepare carbon steel extra-thick plates.

[0061] 1. Slab processing: Select two carbon steel slabs with a size of 1000mm long x 600mm wide x 200mm thick. The carbon steel plate is Q345. Along the length direction of the slab, process triangular protrusions on the surface of two carbon steel slabs respectively, the number of triangular protrusions is 8, the triangular protrusions are continuously distributed, the height of the triangular protrusions is 20mm, and its width is 100mm. , cleaning the processing surface, removing all oil stains; stacking the processing surfaces of two carbon steel slabs relative to each other, so that the triangular protrusions on the two carbon steel slabs are in a meshing state, thereby obtaining a composite slab.

[0062] 2. Sealing and welding: The composite slabs are welded with equal-length sealing and welding plates to seal the space between adjacent metal slabs, and the sealing and weld...

Abstract

The invention discloses a meshing type composite plate vacuum rolling preparation method. The meshing type composite plate vacuum rolling preparation method includes the steps: processing base plate protrusions and covering plate protrusions, which are matched mutually, on compositing surfaces of a base plate and a covering plate respectively; cleaning the compositing surfaces of the base plate and the covering plate; overlaying the base plate and the covering plate, and enabling the base plate protrusions on the base plate and the covering plate protrusions on the covering plate to be meshed mutually; obtaining a composite plate blank by means of blank assembly; and performing hot rolling so that a composite plate is obtained. The meshing type composite plate vacuum rolling preparation method has the advantages that the base plate protrusions and the covering plate protrusions which are matched mutually are processed on the compositing surfaces of the base plate and the covering plate respectively, so that fitting force between the base plate and the covering plate is increased by the aid of meshing force among the base plate protrusions and the covering plate protrusions, separation of the base plate from the covering plate during rolling is avoided, and rolling quality is improved while process is simple; meanwhile, contact area between the base plate and the covering plate is enlarged (namely, the area of a compositing interface is enlarged), so that compositing strength of the composite plate is enhanced; and the meshing type composite plate vacuum rolling preparation method is applicable to preparation of composite plates.

Description

technical field [0001] The invention relates to a method for preparing a metal composite plate, in particular to a method for preparing a composite plate by meshing vacuum rolling. Background technique [0002] Metal composite panels are composited by two or more metal panels with different properties through special preparation methods. Compared with single metal components, metal composite panels after rational design and combination combine the respective advantages of metal components, and can obtain mechanical, physical and chemical properties that single metals do not have. In recent decades, the development, production and application of metal composite panels have attracted more and more attention. This composite material has been widely used in aerospace, petroleum, chemical industry, metallurgy, machinery, automobile, ship, construction and other fields. [0003] At present, the preparation methods of metal clad plates mainly include: explosive cladding method, c...
