Production method of wide titanium steel composite plate

Abstract

The invention relates to a production method of a wide titanium steel composite plate. The production method comprises the steps of machining and processing a blank, machining and processing a frame,coating an isolating agent on the titanium plate and then carrying out seal welding, assembling to form a titanium steel composite blank, centering the titanium steel composite blank, vacuumizing andwelding, inspecting welding seams, rolling and the like; and two titanium steel composite plate with target depth can be manufactured in one production process. According to the production method, theintegrated frame is adopted to replace a plurality of baffle strips for seal welding, so that the number of welding joints is reduced, the welding efficiency is improved, the welding heat input to corners is reduced, the heat influence on a base material structure in the welding process is reduced, and the welding quality is further improved; and an annular groove is formed in the frame, so thatthe phenomenon that the corner strength of a rolled finished composite plate is low due to the corner effect is avoided.

Description

technical field [0001] The invention relates to the technical field of metal composite material processing, in particular to a production method of a wide specification titanium steel composite plate. Background technique [0002] The rapid development of science and technology has put forward higher requirements for metal manufacturing and processing technology. In practical applications, the structure of a single material is often difficult to meet the requirements of use. The composite structure of dissimilar materials can combine the advantages of two materials. Minimize cost reduction and performance improvement. [0003] Among the metal composite materials, the titanium-steel clad plate not only has the excellent corrosion resistance of the titanium clad layer, but also has the strength and plasticity of the base structural steel. Compared with the titanium plate, its economic cost is greatly reduced, especially the double-sided titanium-steel clad plate , because the...

AI Technical Summary

Problems solved by technology

[0008] The above technical solutions all have the following problems: the use of carbon steel bars or titanium bars for sealing and welding of the composite billet puts forward higher requirements for the machining of the clamping bars, and if the flatness is not enough, the vacuum electron beam cannot be used for sealing and welding

At the same time, its sealing and welding process is relatively complicated, not only need to seal and weld 8 long straight side welds, but also need to carry out 4 short vertical side welding seams

Because the same position is repeatedly affected by welding heat, in the subsequent heating and rolling process, the corners are prone to cracking and sealing welding failure.
