asymmetric rolling apparatus, asymmetric rolling method and rolling material that has been produced using the

摘要

According to one aspect of the present invention, asymmetric rolling method of rolling rolls having a diameter different from each other and rotate at the same rotational linear velocity, using a work roll (s) that form a pair, rolling the material to be rolled is provided is. According to one further aspect of the present invention, a first roll that contacts the first surface of the rolled material, has a larger diameter than the first roll, a second surface which is opposite side of the first surface a second roll to be contacted with the ratio of the rotational angular velocity of the first roll and the second roll to be adjusted, and asymmetric rolling apparatus including, for supplying a power supply unit to power to the first roll and the second roll There are provided.
