Method and installation for manufacturing thin metal strip

An installation for manufacturing a thin metal strip, comprising:

• a cooling roll rotating at a high speed,
• a hot metal pouring port having a slit nozzle of 50-350 mm in width for pouring the molten metal onto an outer peripheral surface of the cooling roll,
• an air nozzle for blowing compression gas from a substantially tangential direction of the outer peripheral surface of the cooling roll toward the thin metal strip to separate the thin metal strip,
• a suction type belt conveyor for adsorbing and transporting the separated thin metal strip with a permeable belt by sucking air with a suction box, and
• a take-up reel winding the transported thin metal strip in form of a coil,
• wherein a nearest approaching distance L between the cooling roll and the suction type belt conveyor is 2-50 mm and a suction width S of a suction box arranged in the suction type belt conveyor is 1.2-2.5 times of a width W of the thin metal strip.
