Embodiment 1

[0025] The specifications of the bimetal composite board are: 4.5×1020×Cmm, the target width of the strips 3 is: 950mm, the thickness of the cladding material 1 is 2.5mm, and the cladding material 1 is 65Mn (use requirements: the minimum thickness of the cladding is guaranteed to be ≥ 2mm ), the thickness of the base material 2 is 2.0mm, and the base material 2 is Q235.

[0026] Since the thickness of the two sides of the bimetallic composite plate will be thinned after rolling, in order to ensure that the thickness of the clad material and the total thickness of the material meet the end use requirements after stripping, the total thickness of the bimetallic composite material and the cladding before stripping The thickness of material 1 is measured separately, and the results show that at -475mm from the center point, the average thickness of cladding material 1 (wear-resistant layer) is: 2.10mm, and the total average thickness of bimetallic composite material is: 4.50mm; the...

Embodiment 2

[0037] The specifications of the bimetallic composite material are: 4.5×1020×Cmm, the target width of the strips 3 is: 420mm, the thickness of the cladding material is 2.5mm, and the cladding material is 65Mn (use requirements: the minimum thickness of the cladding layer is guaranteed to be ≥ 2mm), the thickness of the base layer 2.0mm, base material is Q235.

[0038]Since the thickness of the two sides of the bimetallic composite material will be thinned after rolling, in order to ensure that the cladding thickness and total material thickness of the material after slitting meet the final use requirements, the total cross-sectional thickness and cladding of the bimetallic composite material before slitting The thicknesses of the layered materials were measured separately, and the results showed that the average thickness of the composite material 1 at -460mm from the center point was 2.155mm, and the total average thickness of the bimetallic composite material was 4.502mm; the...

Abstract

The invention discloses a longitudinal shearing splitting method of a metallic composite. The longitudinal shearing splitting method comprises the steps that the number of split strips is determined according to target splitting width and the actual width of a metallic composite plate; row cutter sets with the number matched with that of the split strips are arranged on a longitudinal shearing line and are composed of upper cutters and lower cutters, the cutters at the two ends of the upper cutters or the lower cutters are located at the outermost ends at the same time by adjusting the upper cutters or the lower cutters of the row cutter sets, and then the clearance between every two cutters is adjusted according to rules; the metallic composite plate is fed into the longitudinal shearing line, and the composite is made to face the cutters at the two ends, namely, the upper cutters or the lower cutters located at the outermost ends at the same time to ensure the composite is in an outwards-bent state always in the longitudinal shearing splitting process; longitudinal shearing splitting is carried out on the metallic composite plate according to the rules, and metallic composite strips with the target width can be obtained. The metallic composite strips meeting requirements can be obtained through one-time longitudinal shearing splitting. The problem that the metallic composite is layered in the longitudinal shearing splitting process is solved fundamentally, adverse effects of layering on subsequent processing and using are completely eradicated, and product quality is improved.

Description

technical field [0001] The invention relates to a slitting and slitting method for bimetallic composite materials, and belongs to the technical field of slitting composite materials. Background technique [0002] Bimetallic composite material is a newly developed steel variety. The composite material uses ordinary carbon steel as the base material, and wear-resistant steel or stainless steel as the cladding material, and is composited as a whole through the metallurgical combination method of hot rolling. The base material (carbon steel) can provide sufficient structural strength, and has good formability and weldability at the same time; the clad layer (wear-resistant steel or stainless steel) material as the surface layer material has high hardness and good finish, and can Ensure sufficient wear and corrosion resistance. [0003] In the past, the specific process of slitting and slitting a single material is: arranging knives according to the target width → setting the b...
