Problems solved by technology

The commonly used welding manufacturing methods are surfacing welding method and stack rolling method. It is difficult to ensure reliable and uniform welding of the welded copper alloy clad steel plate. The bonding rate between the copper-containing gold-containing plate and the carbon steel substrate is low, and the bonding rate is only 65-70%.

Embodiment 1

[0035] Substrate, double board and its technical requirements

[0036] 1. Substrate: Q235 in the national standard GB700

[0037] Length 4050mm Width 550mm Thick 45mm

[0038] 2. The compound plate is Cr0.5Cu chrome copper steel alloy plate in the national standard GB2045.

[0039] Length 4100mm Width 600mm Thick 17mm

[0040] The embodiment of the manufacturing method of this chrome-copper alloy steel clad plate is the following steps in sequence:

[0041] I. Match

[0042] The chromium-copper alloy plate Cr05Cu and the ordinary carbon steel plate Q235B that meet the national standards and technical requirements for use will be inspected and assembled according to the requirements of the final product.

[0043] II. Stress grooves are opened around the chrome-copper alloy plate

[0044] According to the plane size of the base plate, explosive welding stress grooves are opened around the joint surface of the chrome-copper alloy double plate. The depth of the stress groove ...

Embodiment 2

[0058] The difference between this embodiment and the first embodiment is that the material of the substrate is Q235 carbon steel plate in GB700, the material of the double plate is QA17 bronze alloy plate in GB / T2043, and the steps of the manufacturing method are the same as those in the first embodiment. The explosive combination rate reaches 99.90%.

Embodiment 3

[0060] The difference between this example and Example 1 is that the material of the base plate is Q255 carbon steel plate in GB700, the material of the double plate is QSn6.5-0.1 bronze plate in GB / T2040, and the drug frame is directly placed on the double plate Above, the steps of the manufacturing method are the same as those in Embodiment 1. The explosive combination rate reaches 99.40%.

Abstract

The invention provides a method used for manufacturing a copper alloy composite steel plate; the substrate material is carbon steel plate and the composite plate is copper alloy plate; the manufacture method comprises the manufacture steps as follows: I matching: copper alloy composite plate and normal carbon steel plate which comply with the national standard and usage technical requirement according to the detection are combined in pairs according to the requirement of final products; II: stress troughs of 8-10mm deep and 10-12mm wide are arranged at the circumference of the copper alloy composite plate; III: grinding the surface: oxides and sundries on the explosive combination surface of the substrate and the composite plate are removed; subsequently, a protection layer is uniformly coated on the contact surface of composite plate and dynamite; IV explosive welding: the composite plate and the substrate are supported by copper fulcrum or aluminium fulcrum and welded together by virtue of explosive welding. The combination rate of the manufacture method of the copper alloy plate and the composite steel is more than 99%, with the hardness of HB130-150, thus completely meeting the requirement of copper motor plate on the hardness.

Description

technical field [0001] The invention relates to a manufacturing method of a composite steel plate of a copper alloy plate, in particular to a welding manufacturing method of a copper-containing alloy plate, especially a chromium-copper alloy steel clad steel plate, by explosive welding. Background technique [0002] The copper alloy clad steel plate is mainly composed of two parts, one of which is explosively welded composite material, which uses copper-containing alloy plate such as Cr05Cu chrome bronze plate; the other part is explosively welded base material, which uses ordinary carbon steel plate such as Q235 ordinary steel plate. The commonly used welding manufacturing methods are surfacing welding method and stack rolling method. It is difficult to ensure reliable and uniform welding of the welded copper alloy clad steel plate. The bonding rate between the copper-containing gold-containing plate and the carbon steel substrate is low, and the bonding rate is only 65-70%....
