The Kocks method is known as a method of rolling wire rods by the three-roll system with a slight tension, but the concrete rolling conditions, such as the effects of the size and the shape of billets and the rolling tension on the reduction in area and the shape of the wire rod after rolling, are not available.
The authors carried out rolling tests using Plasticine as a modelling material of steel in hot working. The results show that if the size and the shape of billets before rolling are known, the shape of billets after rolling and reduction in area can be determined at every rolling tension, and thus it has become possible to decide the most appropiate rolling pass schedule of the three-roll system.
