An endless belt work hardening apparatus including a pair of rotatable supporting rolls, a work roll disposed between the supporting rolls and a pair of tension rolls having disposed therebetween the work roll. The endless belt is positioned in the apparatus so that the tension rolls and the work roll engage the inner major surface of the endless belt and the supporting rolls engage against the outer major surface of the endless belt. The tension rolls are moved away from each other and the supporting rolls are rotated to reduce the thickness of the endless belt and work harden the endless belt. Associated methods of work hardening an endless belt for use in a belt caster and manufacturing an endless belt for use in a belt caster are also disclosed. |
