Abstract

PURPOSE:To directly execute continuous casting of a clad steel plate from molten metal under using a drum type slab continuous caster by dividing the space formed by side weirs pushing to the end faces of two drums into two by a partition weir and pouring molten metals having different quality for each other into two divided spaces respectively. CONSTITUTION:The partition weir 6 is arranged into the space formed by two water cooling drums 1, 1' and two side weirs 2, 2'. And, the molten metals 3, 3' stored in tundishes 4, 4' are poured into the spaces divided by the partition weir 6 through nozzles 5, 5'. The molten metals 3, 3' are cooled by contacting with surfaces of the water cooling drums 1, 1' respectively, to form solidified shells 7, 7'. And, the solidified shells 7, 7' are integrated at a neutral point P of the water cooling drums 1, 1', to cast the clad steel plate 8 having two layers.

In the method for producing a clad steel sheet using the previously proposed means, it is necessary to fuse the molten metal and the metal plate, and for this purpose, the melting point of the metal plate must be lower than the melting point of the molten metal. Moreover, since it is impossible to formulate a compound with a slight difference in melting point, the previously proposed method has the disadvantage that it can only use materials with a considerably large dot, and there is also a limit to the length of the metal plate. However, it also has drawbacks such as requiring a process to connect the metal plates.
