The process of rolling titanium strip foil is in principle the same as that of rolling plate, see “Lubrication and Cooling of Titanium Strip Foil”. The production process of titanium strip and foil includes the following basic steps: hot rolling of slabs into flat bars and winding into coils-warm rolling and cold rolling into intermediate strip blanks-cold rolling of strips and foils with a multi-roll mill ; Finishing process.
In the former Soviet Union, industrial pure titanium and titanium alloys can be used to produce foils with a thickness of 0.05 to 0.08 mm and strips with a thickness of 0.1 to 1.5 mm and a width of 200 to 600 mm. The strips are rolled according to the process listed in Table 2-25. system.
When the strip material is rolled to a thickness of 1.6mm, the low-alloyed titanium alloy can be cold-rolled, and the high-alloyed titanium alloy can be warm-rolled in two rolling passes at 720~800T, and the total relative deformation is 50 % And 40%. Between the two rolling passes, the strip blanks need to be pickled and annealed during cold rolling, but only need to be pickled during warm rolling.
Titanium foil is generally a 0.5~0.8mm strip blank in a vacuum annealed state, which is rolled to a final thickness of 0.05–7 through a cold rolling pass of 7-8 cold rolling passes with a total reduction of 20% to 50%. 0.08mm.
