Problems solved by technology
[0007] However, the above patents all use the composite sealing welding of ordinary carbon steel and titanium plate. For high alloy steel, due to the poor welding performance of the steel plate itself, welding cracks are very easy to occur. Therefore, there is no precedent for the production of high alloy steel and titanium composite plate.

Abstract
The invention provides a high-alloy steel titanium composite plate vacuum electron beam assembly soldering and sealing method. According to the high-alloy steel titanium composite plate vacuum electron beam assembly soldering and sealing method, a concave-convex structure catching groove assembly technical scheme is proposed to be combined with a before-welding baking and preheating scheme, and the technical problem that the weld seam of high-alloy steel titanium composite blanks cracks easily is solved. Stable production of a high-alloy steel titanium composite plate is realized. The rollingprocess of the steel titanium composite blank produced through the method is stable and smooth. The flaw detection results of rolled plate blanks are all qualified. All the properties of the rolled plate blanks are far higher than the properties required by users. A powerful technical support is provided for expanding stable production of high-quality high-alloy steel titanium products.
Description
technical field [0001] The invention belongs to the technical field of composite billet production in the metallurgical industry, and in particular relates to a method for sealing and welding high-alloy steel-titanium composite boards with vacuum electron beam assembly. Background technique [0002] Titanium-steel composite plate not only has the excellent corrosion resistance of titanium, but also has the strength and plasticity of steel, and is widely used in the defense industry and civil industry. [0003] At present, there are four main methods for producing titanium-steel clad plates: explosive cladding, diffusion cladding, explosive cladding-rolling and rolling cladding. The composite panels produced by the first two processes are small in size and sometimes difficult to meet user requirements. Due to the commissioning and operation of large-capacity rolling mills, these two methods are only used in some special fields and tend to be eliminated abroad. The latter two...
