Melt spinning

The melt spinning is a method of rapid solidification technology. This is produced by very rapid cooling of a melt materials with special properties. For example, metals in general crystalline, but some alloys with very rapid cool from the molten state as the " metallic glasses " can be obtained. In melt spinning, the melt is to a means of a nozzle - brought copper wheel, where it solidifies immediately - often cooled with water. The cooling rate in this case be about 10,000 to 1,000,000 ° C per second. Due to the high rotational speed of the tape thus obtained is spun off from the wheel.

The melt spinning is sometimes incorrectly as " melt spinning " translated from English, which refers to this process as melt spinning. spin in this case means but do not spin in the sense of " fibers twist together " but " quickly turn " or " spin ". Melt spinning is therefore a much more appropriate term.

Essential for fusion spinning process is the cooling rate. In addition to the temperature difference and the rate at which the melt strikes on the wheel, it naturally depends on the rotational speed; this can be easily varied by this method.
