The preparation method of micron-sized titanium foil is as follows: First, the titanium strip is sent into the rolling mill for one-time rolling to obtain the semi-finished product of one-time rolled titanium foil; Second, after cleaning, it is sent into a vacuum furnace for heat preservation treatment. Third, the semi-finished titanium foil from the first rolling is sent into the rolling mill for the second rolling to obtain the semi-finished titanium foil from the second rolling. 4. After cleaning, it is sent to the vacuum furnace for heat preservation treatment. 5, the semi-finished titanium foil from the secondary rolling is sent into the rolling mill for the third rolling to obtain the semi-finished titanium foil from the third rolling. 6. After cleaning, it is sent into a vacuum furnace for heat preservation treatment to obtain the finished titanium foil. The process of the present invention is simple, energy-saving, and has low energy consumption. It effectively improves production efficiency and can prepare titanium foil with a thickness of only 0.007mm to 0.009mm. The surface of the titanium foil is smooth, free of cracks, peeling, folding, obvious oxidation and impurity indentation defects. It can replace existing titanium foil products and has broad market space and development prospects.
The problem lies in that, in view of the deficiencies of the existing technologies mentioned above, a preparation method for micron-scale titanium foil is provided. This preparation method features a simple process, energy conservation, low energy consumption, and effectively enhances production efficiency. It can produce titanium foil with a thickness ranging from 0.007mm to 0.009mm. Moreover, the surface of the titanium foil is bright, free of cracks, peeling, folding, obvious oxidation, and impurities. It can replace existing titanium foil products. It has a broad market space and promising development prospects.
It can effectively improve the plate shape, reduce the breakage of strips, precisely control the thickness of foil materials, and increase the yield and quality of finished products. The thickness tolerance of the micron-sized titanium foil prepared by the present invention is ±0.0005mm, which is only ± 5.5% to ± 7.5% of the product thickness. The dimensional accuracy is superior to the high-precision requirement (± 10%) of the national standard GB/T 3622-2012(Titanium and titanium alloy strips and foils). Moreover, the plate shape is flat, the surface is smooth, without cracks, peeling, penetrating pinholes, creases, obvious oxidation or impurities being pressed in. It can meet the requirements of national standards for titanium and titanium alloy strip and foil materials, and can replace imported products. It has broad market space and development prospects.
