A2

According to one aspect of the present invention, provided is an asymmetric rolling method. A work piece to be rolled is rolled using one or more working rolls, wherein rolling rolls rotating at a same rotational linear velocity and having diameters different from each other are paired. According to another aspect of the present invention, provided is an asymmetric rolling device, comprising: a first roll contacting the first surface of a work piece; a second roll having a diameter larger than that of the first roll and contacting a second surface, that is, the opposite surface of the first surface; and a power supply section for supplying power to the first roll and the second roll so as to control the ratio of the rotational angular speed of the first roll and the second roll.
