The roll body determines the width of rolled titanium foil, the wider and thinner it is, the harder it is to roll. The width of rolled titanium foil is about 600mm, titanium and titanium alloy foils are mainly used in electronics, instrumentation and other sectors.
Titanium foil has high strength, good corrosion resistance, excellent quality and superior corrosion resistance. Titanium foil is widely used, one is used in the tweeter membrane of loudspeakers and horns, using titanium foil to make high fidelity high, clear and bright sound. Secondly, it is used in magnetic heads of tape recorders, video recorders and magnetic card machines. With pure titanium foil manufactured speaker vibration membrane, so that the speaker creep amount is small, vibration membrane in the usual state in the magnetic bass and high droop response characteristics have been greatly improved. Titanium foil material also involves the following fields: precision parts titanium foil, titanium foil for sound film, vacuum plating special sound film titanium foil, pure titanium foil, titanium alloy foil, titanium with glossy titanium foil, titanium foil with matte surface, curved surface treatment of titanium foil, titanium foil, ultra-thin titanium foil, titanium foil rolled and so on.
The manufacturing method of titanium foil is widely used in flat roll strip rolling, which has high productivity, large scale and large output, and basically uses six-roll cold rolling mill or 20-roll cold rolling mill for production. Mainstream on the titanium strip foil heat treatment there are two ways: vacuum annealing and online protection annealing. Vacuum annealing, is the roll or sheet titanium foil placed in a vacuum furnace for heat treatment; titanium strip foil continuous on-line protection annealing technology introduced, which compared with the vacuum annealing has a high production efficiency, and in the product has a high level of enhancement, but the threshold of the equipment is higher, especially for product quality and titanium strip foil mechanical properties of the indicators on a good guarantee.
