Definitions
- the initially amorphous tape produced using this rapid solidification technology is then wound into magnetically variable magnetic cores, which can be oval, rectangular or round.
- the central step in achieving good soft magnetic properties is the "nanocrystallization" of the alloy strips, which were still amorphous until then. From a soft magnetic point of view, these alloy strips still have poor properties because they have a relatively high magnetostriction
- a crystallization heat treatment tailored to the alloy is carried out, an ultrafine structure is created, ie an alloy structure is formed in which at least 50% of the alloy structure is occupied by body-centered FeSi crystallites. This Crystallites are embedded in an amorphous residual phase made of metals and metalloids.
- the amorphous strips are first wound on ring winding cores with as little tension as possible on special winding machines.
- the amorphous band is first wound into a round ring band core and - if necessary - brought into a shape deviating from the round shape by means of suitable shaping tools.
- suitable winding bodies shapes that deviate from the round shape can also be achieved directly when winding the amorphous tapes into toroidal tape cores.
- the furnace has the shape of a tower furnace in which the annealing zone runs horizontally.
- the horizontally running annealing zone is in turn divided into several separate heating zones, which are provided with separate heating controls.
- At least one, but preferably a plurality of support plates rotating about the tower furnace axis is then provided as the means for conveying the unstacked amorphous toroidal cores through the horizontally extending annealing zone.
- the distribution curve for the magnetic characteristics of a production batch runs broadly, steadily and drops monotonically towards high values.
- the exact course depends on the soft magnetic alloy used, the magnetic core geometry and the stack height.
- FIG. 3 shows the influence of differently thick copper heat sinks on the exothermic behavior in toroidal tape cores, which had dimensions of approximately 21 x 11.5 x 25 mm.
- FIG. Another embodiment of the present invention is illustrated in FIG. Again, the shape of the furnace is that of a tower furnace, but the annealing zone is horizontal.
- the horizontally running annealing zone is in turn divided into several separate heating zones, which are provided with separate heating controls.
- As means for conveying the unstacked amorphous toroidal cores through the horizontally extending annealing zone one, but preferably several, support plates rotating around the tower furnace axis are provided, which serve as heat sinks.
