Problems solved by technology

This method can improve the bonding strength of the interface to a certain extent. However, due to the thin coating, elements such as titanium and iron can penetrate the coating under high temperature or long-term heating conditions and form brittle compounds at the interface, which cannot prevent the interdiffusion of elements. At the same time, due to the lack of good ductility of the coating metal, the problem of uneven interface state will be caused during the rolling process, resulting in the quality of the titanium-steel clad plate prepared by this method cannot be well guaranteed

Abstract

The invention belongs to the field of titanium clad steel plate preparing and processing, and particularly relates to a method for rolling a titanium clad steel plate in the atmospheric environment. The method comprises the following steps: a. assembling: symmetrically assembling according to the sequence of a steel plate, a titanium plate, a copper plate and a steel plate and welding so as to obtain a combined blank; b. heating: heating the combined blank at 950-1,050 DEG C for 2-6 h; c. rolling: rolling the heated combined blank for at least two times, wherein the total rolling deformation is larger than 90%; d. finishing: separating a titanium-steel interface to obtain the titanium clad steel plate. The method is simple in process, and can solve the problem of interface oxidation during the titanium clad steel plate preparing process; the obtained titanium clad steel plate is good in plate type and good in combining effect, and the combining strength is 200 MPa.

Description

technical field [0001] The invention belongs to the field of preparation and processing of titanium-steel clad plates, and in particular relates to a method for rolling titanium-steel clad plates in an atmospheric environment. Background technique [0002] Titanium has good physical, chemical and mechanical properties, but its smelting technology is complicated and the production cost is high, so the price of titanium is very expensive, which greatly limits the promotion and application of titanium. Combining titanium with other metals (such as steel, copper, aluminum, etc.) -Steel composite materials are widely used in chemical, petroleum and other industrial sectors because of their high strength, excellent corrosion resistance and significant economic benefits. [0003] At present, there are four main production methods of titanium-steel clad plates: explosive clad method, diffusion clad method, explosion-rolling and direct rolling method. The direct rolling method is t...
