Abstract

In this method for cooling a main roll, sufficient strength is ensured for a shaft body of the main roll and a peripheral portion thereof, maintenance of the main roll is facilitated, and the shaft body of the main roll and the peripheral portion thereof are efficiently cooled. In this method for manufacturing a ring rolled body, a high-quality ring rolled body is manufactured. The present invention pertains to: a cooling method for a main roll 1 in which the ring rolling main roll 1 is cooled while upwardly facing one side in the axis of rotation direction thereof; and a ring rolled body manufacturing method including said cooling method. In the cooling method, a shaft body 11 is cooled by injecting a liquid W into receiving parts 13, 17 which are recessed from the upper end surface 12c of a mold 12 of the main roll 1 facing one side in the axis of rotation direction and surround the shaft body 11 of the main roll 1. In the ring rolled body manufacturing method, the mold 12 is heated by an induction heating mechanism 6 and the shaft body 11 is cooled through said cooling method, and furthermore, a ring material M is rolled between the main roll 1 and a mandrel 2 to manufacture the ring rolled body.
