Manufacturing method of titanium-steel composite plate

摘要

The present invention relates to a method of manufacturing a titanium-steel composite plate, and bonding performance through manufacturing processes such as blank preparation, surface treatment, release agent brushing, blank symmetric assembly, electron beam sealing strip welding, heating, rolling, deformation correction and plate cutting separation, etc. This strong titanium-steel composite plate is produced. By adding the laminate plate (2) to the composite interface of titanium and steel through the blank assembly process, the titanium and steel in the composite blank cannot sufficiently contact each other, and it prevents the diffusion of elements from each other during the heating process. It controls the mutual generation of brittleness such as compounds, and then, by rolling with a high reduction, destroys the interface oxide film, forms a newly bonded interface between titanium and steel, sufficiently metallurgically bonds, and further, quickly after rolling. By cooling and controlling the formation of brittleness with each other again, a titanium-steel composite plate having no brittle phase and having strong bonding performance is produced. Compared to the case of adding an interlayer nickel foil or copper foil, the operation is simpler, the production cost is lower, and the bonding performance is stronger.
