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.

Embodiment 1

[0056] TA2 and high-alloy steel (carbon equivalent 0.92%) titanium steel composite plate: finished product thickness 2 (TA2) + 8 (steel) mm, width 3500 mm, length 8000 mm, the specific implementation plan is as follows:

[0057] 1) Blank preparation: two pieces of titanium plate TA2 (marked as C and D), both of size 10×1600×2500mm; two pieces of base material high-alloy steel (carbon equivalent 0.92) (marked as A and B): upper substrate A The size is 90×2000×3000mm, the size of the lower base plate B is 100×2000×3000mm; two pieces of IF steel (marked as E, F), the size is 1.0×1600×2500mm.

[0058] 2) Substrate processing: ① Mill the upper and lower surfaces of the upper substrate A and the lower substrate B until the metal luster is exposed on each surface and reach the required thickness; ② In the middle of the upper substrate A, process a groove with a milling machine , the groove depth is: IF steel E + titanium plate C + 2mm, the groove width is the titanium plate specifica...

Abstract

A method for sealing and welding high-alloy steel-titanium composite board blanks by vacuum electron beam. The technical problem that the seam is easy to crack; the stable production of high-alloy steel-titanium composite slab has been realized. The rolling process of the titanium-steel composite slab produced by this technology is stable. Requirements provide strong technical support for expanding the stable production of high-alloy steel and titanium high-quality 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...
