Problems solved by technology

[0004] However, titanium is relatively active, and will oxidize even in a trace amount of oxygen at high temperatures, so it is very easy to react with nitrogen, hydrogen, and oxygen during annealing and other treatments; titanium plates made of pure titanium have poor processability, Can not meet more and more practical applications
The current composite titanium plate mainly adopts titanium steel composite plate or titanium aluminum composite plate, which greatly increases the weight and the surface condition is not ideal, which hinders the application of titanium plate in related fields.

Abstract

The invention discloses a composite titanium plate manufacturing process and system. The manufacturing process comprises the steps of (1) smelting; (2) heat insulation forging and hot rolling; (3) acid pickling; (4) cold rolling; and (5) annealing. Composite titanium plates manufactured from sponge titanium, aluminum debris and lead powder are subjected to three-step heat insulation treatment before forging; an organization microstructure obtained after forging is optimized; an oxide skin on the surface of the organization microstructure can be completely washed away in the acid pickling step, and the peracid phenomenon does not occur; through combination of specific technological condition treatment of cold rolling and annealing, the tensile strengths of the composite titanium plates obtained finally are all more than 520 MPa, the surface smoothness is good, and the cleaning performance is good. In addition, argon is used as a protective gas in the last annealing step, and oxidation is effectively prevented in the annealing process. Softening treatment is conducted before cold rolling, the plasticity of products is improved, and cracks in the cold rolling process are avoided.
