When the molten metal 8b is poured onto the rear wall 2a of the mold flask 2, the molten metal flows between the walls surrounded by the rear wall 2a of the mold flask 2, both side walls 2b and 2c, and the forward running surface 6a of the endless belt B. It is stored as molten metal 8C with a free surface 8d. In this case, the lower surface of the forward running surface 3α is water-cooled and moves in the direction of the arrow 3c, but at this time, the portion of the molten metal 8C near the upper surface of the forward running surface 6a is dragged by the forward running surface 6a. Since it is cooled while moving, a solidified layer is gradually formed near the upper surface of the forward running surface 3a. This solidified layer 9
The Il width of α gradually increases as shown in Fig. 4, but once it exceeds the free surface of the molten metal 8C, it does not increase any further, and the solidified layer (slab) 9C that has completed its growth is an endless belt. The forward running surface 3a of B is also separated and pulled out by the pinch roll 7 in the direction of arrow 9C.

The molten metal is deep at the position where the molten metal flows through the molding flask 2, and the molten metal is shallow at the late stage of the development of the solidified layer 9a. The turbulent flow that accompanies pouring does not impede the stable growth of the solidified layer 9a, nor does it reduce the growth rate of the solidified layer 9a in the later stages of development. When pouring from the gutter 1, there is no need to pay close attention as in conventional equipment.

Stable growth of 9α is not inhibited.
