Two kinds of respective optimum performances of metal are played, not only with combination properties such as excellent physics, chemistry, mechanics, can also be saved
A large amount of precious metals, reduce production cost, thus bimetallic ring be widely used in machinery, automobile, train, ship, metallurgy,
The industrial circles such as chemical industry, the energy, Aero-Space.At present, the main manufacture methods of bimetallic ring are to first pass through ring rolling work
Skill distinguishes two monometallic rings of roll forming, then two monometallic ring combinations are assembled into bimetallic ring.Due to two
Monometallic ring separates roll forming, causes this method process more, wastes time and energy, low production efficiency.And two of roll forming
When monometallic ring is combined assembling, elastic deformation or small plastic deformation only occur for ring contact interface, so as to cause the party
The bimetallic ring interracial contact of method manufacture is of poor quality, and bonding strength is low, it is impossible to meets high performance double metal ring military service performance
With the requirement of service life.
Bimetallic ring rolling, which refers to two kinds of metal ring billets being nested together, to be rolled, in the operation of rolling, due to metal
The factor such as characteristic of the resistance of deformation with temperature and material in itself it is relevant, it is easy to cause deformation uneven, and cause rolling to be lost
Lose.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of using control deformation process in metal material deformation temperature,
The roll forming of bimetallic ring is realized, obtains the good bimetallic ring of performance, size.
In order to solve the above technical problems, side of the two kinds of different titanium alloy combination rollings of the present invention for an annular element
Method, its technical scheme comprise the following steps：
Take two kinds of titanium alloy materials of TC4 and TC6, be cutting into bar by certain specification respectively, then by jumping-up, punching,
For pre-rolling into TC4 alloys ring billet and TC6 alloy ring billets, the internal diameter of TC4 alloy ring billets is equal to the external diameter of TC6 alloy ring billets；Respectively
TC4 alloy ring billets are heated to 880 ± 10 DEG C of insulations, TC6 alloy ring billets are heated to 900 ± 10 DEG C of insulations；By TC4 alloy hoops
The outside that base is enclosed on TC6 alloy ring billets is placed on looping mill and rolled together, obtains the bimetallic ring of two kinds of titanium alloys, its
In, the rolling of TC4 alloy rings is compared for K1, TC6 alloy rings rolling compare for K2；K1/K2=σs/σs', in formula, σsFor TC4
Alloy ring billet rolling deformation drag, σs' it is TC6 alloy ring billet rolling deformation drags.
The TC4 alloys ring billet rolling deformation drag is σs=n σ0, wherein, n is TC4 alloys in rolling corresponding deformation temperature
Under thermal parameter coefficient, σ0For the resistance of deformation of TC4 alloys at normal temperatures.
The TC6 alloys ring billet rolling deformation drag is σs'=n ' σ0', wherein, n ' is TC6 alloys in rolling corresponding deformation
At a temperature of thermal parameter coefficient, σ0' it is the resistance of deformation of TC6 alloys at normal temperatures.
Compared with prior art, beneficial effects of the present invention are as follows：
Two kinds of different titanium alloy combination rollings of the present invention are the method for an annular element, first according to two kinds of titanium alloys
The final size of ring, TC4 alloys ring billet and TC6 alloy ring billets are designed, and determine TC4 alloy rings and TC6 alloy hoops respectively
K is compared in the rolling of part1、K2, further according to K1/K2=σs/σs' determine TC4 alloys ring billet and TC6 alloy rolling deformation drags σs、σs', from
And determine the heating-up temperature of TC4 alloy rings and TC6 alloy rings.At the corresponding temperature, by TC4 alloys ring billet and TC6 alloys
Ring billet is nested together rolling, so as to obtain the bimetallic ring of two kinds of good titanium alloys of performance, size.
