Abstract

The invention discloses a preparation method for micron-grade titanium foil. The preparation method comprises the steps that firstly, a titanium belt is fed into a rolling mill to be subjected to primary rolling, and a primary rolled titanium foil semi-finished product is obtained; second, after being washed, the primary rolled titanium foil semi-finished product is fed into a vacuum furnace to be subjected to heat preservation treatment; thirdly, the primary rolled titanium foil semi-finished product is fed into the rolling mill to be subjected to secondary rolling, and a secondary rolled titanium foil semi-finished product is obtained; fourthly, after being washed, the secondary rolled titanium foil semi-finished product is fed into the vacuum furnace to be subjected to heat preservation treatment; fifthly, the secondary rolled titanium foil semi-finished product is fed into the rolling mill to be subjected to tertiary rolling, and a tertiary rolled titanium foil semi-finished product is obtained; and sixthly, after being washed, the tertiary rolled titanium foil semi-finished product is fed into the vacuum furnace to be subjected to heat preservation treatment, and the finished titanium foil product is obtained. According to the preparation method, the technological process is simple, energy sources are saved, the energy consumption is low, the production efficiency is effectively improved, the titanium foil with the thickness only being 0.007 mm-0.009 mm can be prepared, the titanium foil is smooth in surface, the defects of cracking, peeling, folding, obvious oxidation and impurity pressing-in are not caused, the titanium foil can replace an existing titanium foil product, and the titanium foil has wide market space and development prospects.

Description

technical field [0001] The invention belongs to the technical field of titanium foil preparation, and in particular relates to a preparation method of micron titanium foil. Background technique [0002] Titanium foil is widely used in military sensors, aviation remote sensors, aerospace and electronic terminal vibration plates, civil medical treatment, loudspeakers and other industries. Another application market is as a catalyst carrier to promote oil cracking reactions. In recent years, it is also being developed for marine applications. Titanium foil for anti-corrosion of buildings and regular filling body for catalysts and titanium foil for the development of nuclear instruments for protection and detection, especially in the loudspeaker industry, because of its low hydrogen and iron content, high hardness, good ductility, especially ultra-thin The titanium sound film made of titanium foil has become the first choice for high-quality speakers. The published production p...
