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.
