Systematic experiments were conducted to get a better understanding of how hydrodynamic behavior and cooling characteristics depend on the shape and quality of FeSi77.5B15 wires produced by the in-rotating-water spinning method. X-ray diffraction analysis and differential scanning calorimetry were used to quantify the degree of non-crystallinity of the wire produced. The temperature distribution along the melt jet in the water layer was measured by a photocalorimetric method. The optimum spinning condition to produce long, straight wires was identified. The degree of noncrystallinity could be expressed quantitatively in terms of the heat of crystallization. The temperature distribution along the melt jet was not significantly affected by the operating condition. The average cooling rate between 1200 to 950 °C was estimated to be 6 × 104 to 9 × 104 K/s. The non-crystallinity was considered to be affected by the cooling characteristics in the lower temperature region.
