CONTINUOUS CASTING METHOD OF THIN METALLIC PLATE

摘要

PURPOSE:To cast continuously a thin metallic plate having a sound casting surface, by supplying molten metal continuously into the molten metal stagnating part of a device and drawing the molten metal from the other end while cooling and solidifying the same with endless tracklike upper casting mold and lower casting mold. CONSTITUTION:The molten metal 2' charged into the molten metal stagnating part 4 of a continuous casting installation passes under a gate 5 and moves into the part 4 formed of a belt 8 which is an endless trackline upper casting mold and a lower casting mold 6 having a recessed longitudinal sectional shape. The molten metal 2' solidifies in the form of embedding a dummy bar head therein in this case. When the level of the metal 2' charged into the part 4 ascends to the position of a specified level, the dummy bar is drawn and a solidified ingot 9 is drawn. The mold 8 in this case is rotated in synchronization with the drawing speed. The thin metallic plate of about <=50mm. wall thickness is cast continuously and satisfactorily without breakdown of the ingot.
