In composite roll design, toughened and shock resistant shaft is used along with a locking mechanism for fixing the hardened and wear resistant rolling ring securely in proper place. In the present work an attempt has been made to design and develop a composite ring roll system such that the roll assembly becomes dimensionally as well as functionally same as a conventional mono-block roll system. The circular mechanical shrink fit device is proposed in the composite roll system, has been developed based on the basic principle of friction lock. Torque is transmitted by friction between the contact surfaces of locking system, roll shaft and rolling ring, resulting from tightening of the screws. A scale down model of a composite roll has been developed and tested thoroughly to assess its torque transmitting capacity.
