PURPOSE:To prevent erosion damage by sticking a cushion material formed of a specific material having a specific thickness on the end face of each deformation-preventing die projecting to the inner side of water cooling chambers from the outside wall. CONSTITUTION:An ultrasonically oscillating mold has water-cooling chambers 3, and the inside wall 2 which is in contact with a molten steel is formed by using Cu or a Cu alloy. A cushion material 8 is adhered to the end face of each deformation-preventing die 4 projecting from the outside wall 1 thereof to the inner side 5 of the water-cooling chambers to pack the space between the dice 4 and the wall 2. Any one kind among polyurethane, fluororubber, silicone rubber and polyamide resin is used for the material 8 and is made to 0.1-20mm. thickness. |
