The invention provides a cold rolling titanium foil process, which is used for meeting the requirement of processing ultrathin titanium foils. The method is implemented according to the following steps: (1) selecting and processing blank materials: selecting hydrogen A1 blank material for polishing treatment; (2) primary rolling: polishing the blank, reversing, crossing and repeatedly cold-rolling the blank to the thickness of 0.18-0.22 mm by a multi-roller foil mill for multiple times; (3) rolling a finished product: rolling the foil to 0.05-0.003 mm thickness, degreasing, cleaning and coiling; (4) wrapping and annealing: and (3) wrapping the titanium foil with a zirconium foil which is good for absorbing hydrogen and oxygen in a natural relaxed state of the titanium foil, annealing in a vacuum furnace, taking out of the furnace, and cooling to room temperature to obtain a finished product. The prepared foil has the characteristics of good ductility, high specific strength, excellent tensile strength and rigidity and the like. < | 1- >)
Description
Technical field
The invention belongs to metal material processing technical field, particularly the processing of rare metal foil.
Background technology
Along with industrialization becomes more meticulous making unceasing progress of high accuracy Subminiature electronic product, the vacancy and the international Chinese foil that show domestic foil fall behind place.Colored product foil needs medium-sized and small enterprises of the same trade and constantly makes great efforts just can catch up with and exceed world level.Titanium foil, hafnium paper tinsel, zirconium paper tinsel, niobium paper tinsel, tantalum paper tinsel is had all to need high-quality rolling mill practice to complete in foil industry.
Titanium foil uses extensively in the industry wide such as military project sensor, aero remote sensor, civilian medical treatment, particularly in the utilization of loudspeaker industry, because its hydrogen iron content is low, hardness reaches Hv130 degree, ductility reaches more than 35%, and particularly the titanium sound film of Process of Ti-Foil processing and fabricating becomes the first-selection of high-quality speaker.The production technology of disclosed Titanium board material and foil mainly adopts the hot-rolled temperature of 750 ~ 840 DEG C, and multi-roll mill cold-rolling process also carries out vacuum annealing in 600 ~ 750 DEG C and can obtain various finished product titanium material. and the subsequent treatment process such as hot rolling, annealing, de-scaling, cold rolling, cleaning, vacuum annealing is the viable process preparing Titanium board material and foil.This explained hereafter is just applicable to general thickness titanium foil, and processes for less than 0.1 millimeter foil and be not suitable for.
Summary of the invention
The object of the invention is to provide a kind of cold rolled titanium foil technique, to meet the processing of ultra-thin titanium foil.
Specifically, cold rolled titanium foil technique, it is according to following flow implementation: the process of (1) hair slab selection: select hydrogen content < 0.005%, iron content < 0.02%, thickness close to the TA1 blank material polishing of 1.0mm; (2) preliminary rolling: repeatedly carry out commutation intersection through multiple roll foil mill after the polishing of blank material and be repeatedly cold-rolled to thickness 0.18mm-0.22mm, degrease is cleaned after cutting itemize, then at 600 DEG C-610 DEG C, carry out vacuum annealing, make titanium crystallization again, internal structure is more even; (3) finished product rolling: the foil of breaking down is rolling to 0.05mm-0.003mm thickness again, degrease cleaning rolling; (4) parcel annealing: under titanium foil natural relaxation state, by titanium foil with being good at the metal zirconium paper tinsel parcel inhaling hydrogen oxygen uptake, sends into low vacuum in 1.0 × 10
-3in the vacuum drying oven of Pa, 490 DEG C-510 DEG C annealing, being incubated came out of the stove after 1-2 hour is down to room temperature and is finished product.
The present invention selects the polishing of the satisfactory 1.0mm of hydrogen, iron content thick TA1 blank material, carry out commutation intersection through multiple roll foil mill and be repeatedly cold-rolled to thickness 0.18mm-0.22mm, carry out the vacuum annealing of 600 DEG C after itemize cleaning, make titanium crystallization again, internal structure is more even; Be rolling to 0.05mm-0.015mm thickness again, decontamination cleaning rolling (often roll up weight and be less than 2kg).Under titanium foil natural relaxation state, with being good at the metal zirconium paper tinsel parcel inhaling hydrogen oxygen uptake, send into vacuum 1.0 × 10
-3in the vacuum drying oven of Pa, select 490 DEG C-510 DEG C annealing, being incubated came out of the stove after 1-2 hour is down to room temperature and is finished product.This finished product has that ductility is good, specific strength is high, the excellent feature of tensile strength rigidity.
Innovative point of the present invention: 1. blank material polishing, commutation tandem rolling, titanium is crystallization again.2. with being good at the metal zirconium paper tinsel parcel annealing of inhaling hydrogen oxygen uptake.3. titanium foil finished product ductility is good, specific strength is high, and tensile strength rigidity is excellent.

Detailed description of the invention
Cold rolled titanium foil technique, it is according to following flow implementation: the process of (1) hair slab selection: select hydrogen content < 0.005%, iron content < 0.02%, thickness close to the TA1 blank material polishing of 1.0mm; Carry out vacuum annealing in the process of hair slab selection to eliminate stress simultaneously.(2) preliminary rolling: repeatedly carry out commutation intersection through multiple roll foil mill after the polishing of blank material and be repeatedly cold-rolled to thickness 0.18mm-0.22mm, degrease is cleaned after cutting itemize, then at 600 DEG C-610 DEG C, carry out vacuum annealing, make titanium crystallization again, internal structure is more even; (3) finished product rolling: the foil of breaking down is rolling to 0.05mm-0.003mm thickness again, degrease cleaning rolling; (4) parcel annealing: under titanium foil natural relaxation state, by titanium foil with being good at the metal zirconium paper tinsel parcel inhaling hydrogen oxygen uptake, sends into low vacuum in 1.0 × 10
-3in the vacuum drying oven of Pa, 490 DEG C-510 DEG C annealing, being incubated came out of the stove after 1-2 hour is down to room temperature and is finished product.
Preliminary rolling comprises: (1) split rolling method: blank is repeatedly carried out commutation intersection at multiple roll foil mill and is repeatedly cold-rolled to 0.5mm foil, after cleaning, vacuum annealing, cutting itemize, sampling detects; (2) intermediate rolling: repeatedly carry out commutation through multiple roll foil mill and intersect that cold rolling 0.5mm foil is 0.18-0.20mm is repeatedly semi-finished product, after cutting itemize, cleaning, vacuum annealing, sampling enters finished product rolling after detecting.Described commutation intersect repeatedly cold rolling be foil after a direction rolling one time, at once by rolling again after foil sheet conversion 90 degree.
The titanium sound film that present invention process is made exceedes other material sound film power 5 watts of same model, such as: titanium sound film power in the specification 51 core test of loudspeaker horn of 0.03mm thickness reaches 55 watts, and Japanese same model titanium sound film power only reaches 47-48 watt.And do not produce resonance, the instructions for use of high-quality sound equipment can be reached.Product of the present invention is applied on the products such as titanium sound film and loudspeaker, and having stability stablizes, the feature that titanium sound film yield rate is high.
