Abstract

PURPOSE:To prevent development of vibration and movement of a metal strip and to stabilize detaching of the metal strip from the cooling drum by arranging a pushing roll as facing to one side of a cooling drum at the lower position from drum gap part. CONSTITUTION:At the lower position from the drum gap part 5 between the cooling drums 1a, 1b, the pushing roll 6 is faced to the peripheral surface of the one side of the cooling drum 1b. In surface of the metal strip 4 along the peripheral surface of the cooling drum 1b, the carrying force in proportion to rotating speed is worked. On the other hand, to the surface of the strip 4 on the pushing roll 6 side, too, carrying force in proportion to the rotation speed of the roll 6 is worked. By the difference of the carrying force, the rotating force to clockwise direction in the strip 4 is worked while making the pushing roll 6 as supporting point. In this way, the strip 4 is detached from the peripheral surface of the cooling drum 1b at near the roll 6. Further, in the range from the drum gap 5 to the roll 6, the strip 4 is carried under pushing condition to the peripheral surface of the drum 1b by the roll 6. By this method, the metal strip 4 can be stably carried from the casting apparatus.
