Abstract

PURPOSE:To prevent the thermal deformation of a thin strip by preliminarily heating the outside peripheral surface of a cooling drum and supplying a molten metal to just behind the same to relieve the temp. gradient of the molten metal in the stage of quick solidification. CONSTITUTION:A burner 7 is provided to the lower side of the side face on a gate 2 side of the cooling drum 1 and a cover 8 is disposed. The molten metal 5 is poured into the gate 2 and the outside peripheral surface of the drum 1 is preliminarily heated by the burner 7 to 500-700 deg.C just prior to the supply of the molten metal 5 onto the outside peripheral surface of the cooling drum 1. The heating with the burner 7 is then stopped and the molten metal 5 is supplied from the gate 2 on the outside peripheral surface of the cooling drum 1 under rotation. As a result, the temp. gradient of the molten metal 5 in the stage of the quick solidification thereof is relieved and the thermal stress to be generated is suppressed within the range of elastic deformation. The thermal deformation of a shin sheet 6 is, therefore, prevented.

However, the ribbon 6 manufactured by the method described above has
There is a problem that thermal deformation occurs. The reason why such thermal deformation occurs is that when the molten metal 5 adhering to the outer peripheral surface of the cooling drum 10 is rapidly solidified and the ribbon is cooled by the cooling drum 1, a large amount is generated in the thickness direction and the length direction. A temperature gradient occurs, and the thermal stress generated at this time causes plastic deformation in the ribbon 6. That is, if the temperature gradient in the thickness direction of the ribbon 6 is large, the ribbon deforms away from the cooling drum 1, and the adhesion between the outer peripheral surface of the cooling drum 1 and the ribbon 6 decreases, causing the ribbon to deform. 6 is difficult to peel from the outer circumferential surface of the cooling drum 1, and if the temperature gradient in the longitudinal direction of the ribbon 6 is large, the ribbon 6 tends to contract and buckle.

Such thermal deformation that occurs in the ribbon 6 cannot be completely prevented even by the press rolls 4.4 provided on the top and side surfaces of the cooling drum 1; on the contrary, the deformation is caused by the press rolls 4, 4. It is folded into a ribbon with extremely bad wrap-like wrinkles.
