PURPOSE:To obtain stably and continuously a billet having a good shape by dipping a core material to which required curvature is given into a molten steel from above the molten steel by a delivery deice provided with a bending mechanism thereby sticking the molten steel to the surface of the core material. CONSTITUTION:The core material delivery device 4 provided with the bending mechanism 4 is disposed on the inlet side for dipping and the core material 2, for example, 3 mm thick steel plate, is dipped into the molten steel 7 in a molten steel holding furnace 3 from above and is pulled up while 500 mm R bending deformation is given thereto. The curvature is already plastically deformably given to the material 2 and therefore even if the core material is dipped into the steel 7, the core material has no tendency to the restoration of the original shape. The stable pass line is thus assured and the good billet shape is obtd. Always the prescribed curvature is stably given to the material 2 even if the thickness and shape of the material 2 change and the application of the dip forming method to the field of iron and steel is made advantageous. |
