Description
Technical field
The invention belongs to metal material processing technical field, is related to a kind of processing method of titanium-alloy thin-plate.
Background technology
Titanium alloy not only has less density, good room temperature, high temperature, cryogenic mechanics performance, and in a variety of media
With excellent corrosion resistance, the series of advantages such as solderable, cold/hot shaped, therefore in Aero-Space, petrochemical industry, shipbuilding, vapour
The application that the departments such as car, medicine all succeed.With the development of the industrial technologies such as Aeronautics and Astronautics and ship, titanium alloy is surpassed
The demand of thin plate increasingly increases.At present, domestic titanium alloy plate is in terms of production technology, product quality and specification, with Japan, Europe
Mei Deng developed countries depend on import in the presence of very big gap, especially some ultra-thin titanium alloy plates, far from satisfaction
The domestic market demand.
Method of the titanium-alloy thin-plate frequently with pack ply-rolling is produced at present, i.e., using multiple 4mm-6mm hot rolling titanium alloy sheets
Superposition, welded with steel plate surrounding jacket, then carry out hot rolling.The titanium-alloy thin-plate surface orange peel phenomenon that the method is produced is tight
Weight, follow-up surface treatment is next difficult, but also needs cold rolling again, tedious process, and plate shape is difficult to control, and is significantly impacted
Plate surface quality, even result in scrapping for sheet material.
The content of the invention
It is an object of the invention to provide a kind of processing method of titanium-alloy thin-plate, solves and prepares titanium-alloy thin-plate surface matter
The problem of amount is poor, complex procedures.
The technical solution adopted in the present invention is a kind of processing method of titanium-alloy thin-plate, specifically real according to following steps
Apply：
Step 1, the spot of steel plate and titanium alloy sheet surface cleaned out；
Step 2, laminated titanium-alloy plate is superimposed to form titanium alloy stacking, the titanium alloy stacking after superposition it is upper
Lower two sides is respectively covered with the steel plate after cleaning, and is covered with side seal steel plate strip in titanium alloy stacking avris；
Step 3, steel plate and steel plate strip are welded envelope titanium alloy stacking, form ply rolling bag；
Step 4, ply rolling bag described in step 3 is placed in heating furnace it is heated to 860 DEG C -1000 DEG C, reaches the humidity province
Between the warm 30min of follow-up continuation of insurance come out of the stove, ply rolling bag is rolled using 2800mm four-roller reversible hot milling roll group after coming out of the stove, rolled
During control pass deformation rate be not more than 30%；
Step 5, the ply rolling bag in step 4 after rolling is made annealing treatment, then by the ply rolling after annealed processing
Bag shearing is unpacked, and obtains titanium alloy plate；
Step 6, sanding and pickling processes are carried out to the titanium alloy plate surface obtained in step 5, obtain pack ply-rolling titanium
Latten.
The features of the present invention also resides in：
The thickness in monolayer of titanium alloy sheet is 3mm-4mm；Steel plate, the steel of titanium alloy stacking gross thickness and cladding after superposition
The thickness of bar is identical.
Uniform passage is left on ply rolling bag side seal board, ventilation hole area accounts for the 15% of whole side seal plate suqare.
The finishing temperature of rolling is 850 DEG C -1100 DEG C, is rolled with 5%-20% reduction in pass, total rolling process
Deflection is 45%-85%.
Acid cleaning process uses volumetric concentration as 45% nitric acid, at normal temperatures pickling 15min.
A kind of processing method of titanium-alloy thin-plate of the present invention, titanium alloy plate is coated in outside and surrounding using steel plate,
By titanium alloy sheet relative closure in the box body that a steel plate forms, then heating rolling, ensure that the rolling of titanium alloy plate
Process is carried out in a metastable temperature, it is ensured that the stability of finished sheet.By completing to roll in certain temperature
System can rationally design rolling temperature according to demand, obtain appropriate Phase Proportion, to ensure special performance requirement, and suitable
When completing rolling under high temperature, the processing in the absence of metal is hardened, and will not produce texture, the anisotropy very little of material.The present invention
By selecting suitable deformation temperature, rational deflection and perfect cladding group material mode, by physical property, chemical property and
Room-temperature mechanical property differs greatly steel plate as outsourcing material, using titanium alloy plate as inner core material.Utilize the low price of steel plate
Value is rolled down to certain thickness, produces the inside titanium-alloy thin-plate of high value in outside as protection, cladding bag.
The beneficial effects of the invention are as follows the thickness of cladding titanium alloy sheet used to be reduced to 3mm-4mm by 4mm-6mm, reduces
The cumulative effect of tangerine hull constitution, and be advantageous to control plate shape.Whole process is easily controllable, simple to operate, solves system
The problem of standby titanium-alloy thin-plate surface quality is poor, complex procedures.
