Description

A kind of method that utilization thin-walled major diameter titanium welding pipe produces titanium matter cup/kettle
Technical field
The present invention relates to a kind of method that utilization thin-walled major diameter titanium welding pipe produces titanium matter cup/kettle.
Background technology
The corrosion resistance of the daily necessitiess such as titanium cup, titanium kettle is the several times of stainless steel, completely without Metal peculiar smell, prolonged resistance to With;It is titanium articles for use high temperature resistant, low temperature resistant, can below 600 DEG C long-term use without being deformed, in low temperature -196 ~ -253 Remain to keep preferable ductility and toughness under DEG C environment, and do not have ice-cold sensation.Titanium is physiologically several to human body All it is inert, is unique vegetative nerve and gustatory nerve to people and does not have the daily necessitiess such as effective metal, titanium cup, titanium kettle Safety non-toxic, also light weight, firmly, it is small specific heat, low thermal conductivity, nontoxic and the features such as without anaphylaxis, in food and life There is great potential in articles for use field.
Conventional wall thickness >=the 0.9mm of titanium seamless tubes, wall thickness is thicker, there are problems that the uniform yield rate of wall unevenness is low, and From the titanium welding pipe of 0.4 ~ 0.9mm of wall thickness, economic benefit ratio seamless pipe more preferably, but processes seamless pipe of the wall thickness less than 0.9mm Difficulty is big, and input cost is more.Because titanium has the characteristics such as excellent corrosion resistance, the U.S., Japan and France etc. in large-scale power In the heat exchanger and condenser of nuclear power station, titanium thin walled welds pipe is widely applied, China progressively draws from the eighties in 20th century A plurality of titanium welding pipe production line is entered, the titanium welding pipe of the various outer diameter specification of 0.5 ~ 2mm of wall thickness can have been produced.With China's electric power, The development of nuclear power, desalinization and heat exchange industry, the application of thin-walled welding pipe is more and more, development is also increasingly faster, nowadays I The annual production capacity of state's titanium welding pipe has been over 10,000 tons, and specifications and characteristics meets related international standard, and starts to method The states such as state, Norway export titanium welding pipe.
Due to high yield rate, advantages, thin-walled welding pipe turns into a kind of trend of current tubing production, thin-walled major diameter titanium The wall thickness of welded tube is generally 0.4 ~ 0.8mm, 50 ~ 120mm of diameter, but the principal element of restriction China titanium welding pipe development is titanium band Quality is unqualified and the failure welding of large diameter welded pipe, when producing parts using titanium welding pipe, often cracking phenomenon, and Cracking position majority is in weld seam annex;The indexs such as the mechanical property and machinability of titanium band and titanium tube are main by O and N content(Or O Equivalent)Determined Deng impurity, O content increases, the difficulty of machining deformation will increase.Particularly TA1 titanium tubes material is soft, if during shaping Speed and mould are mismatched, and easily cause the defect such as impression and scuffing, and undercut, step, weldering leakage and weld seam oxygen occur during welding Change etc. defect and cause failure welding.In order to obtain the parts of good utilization thin-wall titanium welding pipe preparation, it is necessary to be directed to difference Purposes select different titanium bands, while to control shaping, welding and annealing process, the good weldquality of acquisition.
The content of the invention
The purpose of the present invention is by being molded and welding, obtain the good thin-walled major diameter titanium welding pipe of weld seam, and provide one Kind of the method that titanium matter cup/kettle is produced using the thin-walled major diameter titanium welding pipe, the 0.4 ~ 0.8mm of wall thickness of titanium welding pipe, diameter 50 ~ 120mm。

Wherein, step(1)In titanium plate base use I grade of pure titanium of TA1, the control of titanium plate base composition is oxygen content≤0.07%. Nitrogen content≤0.01%.
Wherein, step(1)In titanium plate base use II grade of pure titanium of TA1, the control of titanium plate base composition be oxygen content≤ 0.06%.Nitrogen content≤0.008%.
Further, step(3)When preparing titanium matter cup/kettle using bulging method, the bulging rate of titanium welding pipe is no more than 20%.
Further, step(3)When preparing titanium matter cup/kettle using bulging method, the bulging rate of titanium welding pipe is 20 ~ 40%.
Wherein, step(1)Coiled strip is placed in vacuum cover annealing, annealing process is:Pressure-fired argon gas is protected, 600 ~ 700 DEG C of 1 ~ 10h of insulation.
Wherein, step(1)Middle hot-rolling method is rolled using Steckel mill, and coiled material enters temperature after often rolling a time Spend in the high temperature furnace for 800 DEG C and wind, next passage is then rolled again;Step(1)Middle cold rolling coil belt method is rolled using reversible Machine is cold rolling, wherein, the rolling process deflection of the coiled strip in cold rolling coil belt method is not less than 50%;Wherein, rolling process deflection refers to The ratio between rolling Reducing thickness and ingoing ga(u)ge.
Wherein, step(1)4 ~ 9 grades of the grain size of obtained finished titanium strip, specification is the finished product titanium of 500mm × 500mm The grain size number difference of band is no more than 0.5 grade.
Wherein, the vertical weldering of the titanium tube of bending is welded into titanium welding pipe, during welding, is welded to inner side from the outside of titanium tube, Single-side welding double-side forming is realized, wherein, the weld seam of welding and the titanium tube base materials of minimum thickness > 90% of titanium tube base material intersection Thickness, outside weld reinforcement≤0.05mm, inside weld reinforcement≤0.1mm, the hardness of weld metal zone is higher than titanium tube matrix hardness, the two Difference < 30HV.
Wherein, step(2)The anneal processing steps of titanium welding pipe are:Titanium welding pipe is loaded into vaccum sensitive stove, vaccum sensitive stove Temperature is 550 ~ 700 DEG C, is incubated 0.1 ~ 3min at such a temperature, and under argon atmosphere forced cooling to room temperature, then Come out of the stove, test.
Wherein, step(3)The method for preparing titanium matter cup/kettle using bulging method is:Using consistent with titanium matter cup/kettle profile Elastic mould is expanded into type in hydraulic press reclaimed water, and hydraulic pressure is 0 ~ 100MPa.
