Zusammenfassung: | PURPOSE:To permit the speedup of casting speed by a method wherein guiding means are provided at the outside of both side ends of die slit while a contacting area between the guiding means and the edges of molten body is regulated so that the edges, the vicinities of the edges and the central section in the widthwise direction of the sheet-like molten body arrive at a cooling surface in parallel to the die slit substantially under keeping a linear configuration substantially. CONSTITUTION:The edge of the molten body, extruded out of the die slit, flows down on the surface of the guiding means 10 vertically substantially and flows to the side end 22 of a guiding surface along the bottom side 21 of the guiding surface into the take-off direction of the molten body, then, is released from the side end and arrives at the cooling surface through free space. In order to prevent the curl at the edge of sheet-like molten body and make the landing line of the sheet-like molten body to be a straight line, a releasing point 30 from the guiding means should be in the same plane as the stream line 13 of the central part of the body in case they are observed from a side direction. In case the landing point of the edge is moved to the upstream side of the landing point of the central part in the cooling surface, a high-speed casting effect, due to electrostatic adhesion, will not be changed. |
