METHOD AND INSTALLATION FOR MANUFACTURING THIN METAL STRIP |
摘要 |
A method for manufacturing a thin metal strip by pouring and rapidly solidifying molten metal onto a cooling roll rotating at a high speed to form a thin metal strip having a width of 50˜350 mm, blowing compression gas from substantially a tangential direction of the cooling roll toward the thin metal strip to separate the thin metal strip from the cooling roll, adsorbing the separated thin metal strip with a permeable belt of a suction type belt conveyor, and transporting to a take-up reel to wind in form of a coil, the thin metal strip is adsorbed by the belt under conditions that 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. |

1. A method for manufacturing a thin metal strip comprising:
pouring and rapidly solidifying molten metal onto an outer peripheral surface of a cooling roll rotating at a high speed to form a thin metal strip having a width of 50˜350 mm, blowing compression gas from substantially a tangential direction of the cooling roll toward the thin metal strip to separate the thin metal strip from the cooling roll, adsorbing the separated thin metal strip with a permeable belt of a suction type belt conveyor, and transporting to a take-up reel to wind in form of a coil, wherein the thin metal strip is adsorbed by the belt under conditions that 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. |
