Embodiment 1

[0033] Example 1: Polish the surface of 0.1 mm thick stainless steel plate and 0.5 mm thick aluminum plate to smooth, and clean the oil stain; the pretreated stainless steel plate and aluminum plate are stacked in the order of stainless steel plate / aluminum plate / stainless steel plate to form a laminated plate 4 , laminated plate 4 superimposed thickness t 0 =0.7mm; first pass the laminated plate 4 through the clamping device 3 and the rolling mill 2 in turn, and then use the clamp body 1-1 to clamp and fix the tail of the laminated plate 4; adjust the working distance of the clamping device 3 to 0.65 mm, adjust the roll spacing of rolling mill 2 to 0.64 mm, set the roll line speed of rolling mill 2 to 5m / min, and set the moving speed of clamp body 1-1 to 5.25m / min. Such as figure 2 The microstructure of the cross-section of the stainless steel / aluminum / stainless steel laminated composite plate is shown, and it can be concluded that the interfacial bonding of the stainless s...

Embodiment 2

[0034] Example 2: Polish the surface of 0.3mm thick stainless steel plate and 1.0mm thick aluminum plate to smooth, clean up the oil stain; the pretreated stainless steel plate and aluminum plate are stacked in the order of stainless steel plate / aluminum plate / stainless steel plate to form a laminated plate 4. Laminated board 4 superimposed thickness t 0 =1.6mm; first pass the laminated plate 4 through the clamping device 3 and the rolling mill 2 in turn, and then use the clamp body 1-1 to clamp and fix the tail of the laminated plate 4; adjust the working distance of the clamping device 3 to 1.5 mm, adjust the roll spacing of rolling mill 2 to 1.5 mm, set the roll line speed of rolling mill 2 to 3m / min, and set the moving speed of clamp body 1-1 to 3.3m / min.

Embodiment 3

[0035]Example 3: The surfaces of the 0.5 mm thick stainless steel plate and the 4.0 mm thick aluminum plate are polished smooth, and the oil stains are cleaned; the pretreated stainless steel plate and aluminum plate are stacked in the order of stainless steel plate / aluminum plate / stainless steel plate to form a laminated plate 4 , laminated plate 4 superimposed thickness t 0 =5mm; first pass the laminated plate 4 through the clamping device 3 and the rolling mill 2 in sequence, and then use the clamp body 1-1 to clamp and fix the tail of the laminated plate 4; adjust the working distance of the clamping device 3 to 4.5 mm , adjust the roll spacing of rolling mill 2 to 4..5mm, set the roll line speed of rolling mill 2 to 2m / min, and set the moving speed of clamp body 1-1 to 3m / min.

Abstract

The invention relates to a layered composite plate, in particular to a device and a method for preparing a stainless steel / aluminum / stainless steel layered composite plate. The invention provides a novel device and method for preparing the stainless steel / aluminum / stainless steel layered composite plate so as to solve the problem that an existing device and method for preparing the stainless steel / aluminum / stainless steel layered composite plate have the defects in the prior art. A laminated plate sequentially penetrates through a gripping device and a rolling mill and is gripped and fixed through a clamp device, the working distance and the roll gap distance of the gripping device and the roll gap distance of the rolling mill are adjusted to be smaller than the thickness of the laminatedplate, and the rolling speed of the rolling mill and the moving speed of a clamp are set; and tension in the rolling direction is generated through the difference between the moving speed of the clampand the linear speed of a roller, drawing deformation is introduced in the rolling process through resistance generated by the gripping device, deformation nonuniformity of metal difficult to deformon a surface layer and metal prone to deform at the center portion is restrained or eliminated, and interface bonding is good.

Description

technical field [0001] The invention relates to a layered composite board, in particular to an equipment and method for preparing a stainless steel / aluminum / stainless steel layered composite board. Background technique [0002] Stainless steel has the characteristics of high strength and toughness, wear resistance, corrosion resistance, and high price, and is widely used in transportation, construction, home and other fields; aluminum has the characteristics of low density, good plasticity, good thermal conductivity, and relatively low price; if the two Combining two kinds of materials to form a stainless steel / aluminum / stainless steel layered composite board can have the advantages of high strength, toughness, wear resistance and corrosion resistance of the stainless steel surface, light weight of aluminum, and good thermal conductivity. [0003] At present, the composite plate is mainly prepared by rolling in a rolling mill, and the stainless steel plate and the aluminum p...
