鋳造するものである。(Prior art) As shown in Fig. 2, the roll type continuous casting method uses two rolls 1 and 1 that are rotatably arranged parallel to each other at a predetermined interval.
A molten metal 4 is formed by these two rolls 1 and two fixed weirs 2.2 placed at both ends of are rotated in directions facing each other as shown by arrows A and B, respectively, and while cooling the molten metal 4 by each of these rolls 1.1, these rolls 1.
The steel plate 6 is continuously cast by drawing it out from the gap 5 and solidifying it.

る。(Problems to be Solved by the Invention) However, in the conventional roll type continuous casting method described above, cooling of the molten metal 4 is insufficient when passing through the gap 5 of the two rolls 1.1. A so-called breakout, in which unsolidified portions exist in the metal gJ plate 6 to be cast, is likely to occur. Furthermore, if sufficient cooling is performed in the gap 5, there is a risk that the molten metal 4 may already solidify in the sump 3. Therefore, there is a problem in that it is difficult to prevent the molten metal from solidifying in the molten metal sump 3 and to prevent breakout of the cast thin metal plate 6 from occurring.
