As the outer parts of a hot roll for sheat iron are subjected to repeated heating and cooling by the intermittent passages of hot materials, there arise numerous small cracks on its surface. In this research, we considered theoretically the mechanism of occurrence of these cracks and studied the necessary characters of the material of this roll in order to prevent these cracking. From the data of rolling operations we calculated the temperature variations of the outer parts of the roll, and by the method of graphical solution we analysed the stresses on the roll surface, and examined the influences of roll material upon the stresses.
