Claims
- 1. A method of producing a rapidly solidified microcrystalline metallic tape by continuously pouring molten metal through a nozzle onto surfaces of a pair of cooling members rotating at a high speed to rapidly solidify it and then coiling the resulting rapidly solidified metallic tape, characterized by the steps of initially cutting an imperfect portion of the solidified tape with a cutting means installed in a vertical path just beneath said cooling rolls, catching a steady tip of the cut tape and transporting the tape through a cooling region, and coiling said tape into a roll.
- 2. The method according to claim 1, wherein a travelling line speed of said metallic tape is decreased at said initial production stage including a last production stage in the cutting of said non-steady portion, and increased at the remaining steady stage.
- 3. The method according to claim 1, including a first and second rolling surface, and the step of increasing the speed of the first rolling surface with respect to the second rolling surface.
- 4. The method according to claim 1, wherein said cooling of the metallic tape is carried out with gas or mist or fog.
- 5. The method according to claim 1, wherein tension control of said metallic tape while being transported from the cooling members to coiling is separately carried out at a front region wherein said metallic tape is at low tension, and a rear region wherein said metallic tape is at high tension.
