Embodiment Construction

[0009] The cold-rolled titanium foil process is implemented according to the following process: (1) rough material selection treatment: select TA1 rough material with hydrogen content -3 In a vacuum furnace of Pa, anneal at 490°C-510°C, keep warm for 1-2 hours, and then cool down to room temperature to be the finished product.

[0010] Preliminary rolling includes: (1) Billet rolling: the billet is repeatedly cold-rolled to 0.5mm foil in a multi-roller foil mill, cleaned, vacuum annealed, cut into strips, and then sampled for inspection; (2 ) Intermediate rolling: through multi-roller foil rolling mills, reverse crossing and repeated cold rolling of 0.5mm foil to 0.18-0.20mm is a semi-finished product. After cleaning, vacuum annealing, cutting and slitting, sampling and testing are carried out before rolling into finished products. The reversing and cross-repetitive cold rolling means that after the foil is rolled once in one direction, the foil sheet is immediately turned by ...

Abstract

The invention provides a cold rolling titanium foil process to meet requirements of ultrathin titanium foil machining. The cold rolling titanium foil process is carried out according to the following procedures that (1) blank materials are chosen and processed: hydrogen aluminum blank materials are chosen to be processed in a polished mode; (2) primary rolling is achieved: the blank materials are polished, the materials are reversed, intersected and repeatedly rolled through a multi-roll foil rolling machine for a plurality of times to achieve the fact that the thickness of the materials reaches 0.18mm-0.22mm; (3) end products are rolled: foil materials after primary rolling are rolled to the foil materials with the thickness of 0.05mm-0.003mm, and fatting, cleaning and lapping are achieved; and (4) packaging and annealing are achieved: under the state that titanium foil is naturally relaxed, the titanium foil is packaged through metal zirconium foil good at hydrogen absorption and oxygen absorption, and after the annealing is achieved in a vacuum furnace, the materials out of the furnace are cooled to be in the room temperature to become end products. The prepared foil materials have the advantages of being good in malleability, high in specific strength, excellent in strength of extension and rigidity, and the like.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, in particular to the processing of rare metal foil materials. Background technique [0002] With the continuous advancement of industrialized, refined, high-precision and ultra-small electronic products, it shows the vacancy of domestic foil materials and the backwardness of international Chinese foil materials. Foils for non-ferrous products need continuous efforts of small and medium-sized enterprises in the same industry to catch up with and exceed the international level. In the foil industry, titanium foil, hafnium foil, zirconium foil, niobium foil, and tantalum foil all require high-quality rolling processes. [0003] Titanium foil is widely used in military sensors, aviation remote sensors, civilian medical and other industries, especially in the loudspeaker industry. The titanium sound film made of thin titanium foil has become the first choice for high-quality speake...
