PURPOSE: To form a stable pass line up to a take-up machine by introducing stably a metallic strip at the time of introducing the rapid cooled metal strip by peeling off the strip from the surface of a single roll in a single roll type rapid cooled strip producing device.
CONSTITUTION: A gas header 10 is provided along the peripheral surface of the cooling roll 2 and an ejector is formed at a space between the cooling roll 2 and the gas header 10. The space is made to 0.5-10mm at the inlet side of the header 12 and 0.3-3mm at the outlet side of the header 10. Further, the outlet position θ of the header is made to in the range of 1/6-1/2 round at the front in the advancing direction of the cooling roll from a spouting nozzle for the molten metal. An endless belt 6 is arranged closely to the cooling roll 2 in the non-contacting condition from the outlet of the header 10. Angle between the tangent of the cooling nozzle 2 at the position most nearest to the endless belt 6 and the axis of the endless belt 6 is made -10° to +10°. The space between the endless belt 6 and the cooling roll 2 is made 0.1-10mm. Angle α between the endless belt 1 and the tangent of the cooling nozzle 2 at the outlet side of the ejector 4 is made -10° to +10°.
