本発明は、双ロール法による急冷薄帯の製造方
法および装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method and apparatus for producing a quenched ribbon using a twin roll method.
＜従来の技術＞
一般に、溶融金属急冷法による急冷薄帯作製法

帯３を得るものである。<Prior art> In general, there are two methods for producing a quenched ribbon using a molten metal quenching method: a single roll method and a twin roll method.
As shown in Fig. a, the twin roll method is a method in which molten metal 1 is continuously supplied to the surface of a cooling roll 2 rotating at high speed through a pouring nozzle 13 and rapidly solidified to obtain a ribbon 3.

ない欠点があつた。 When manufacturing a ribbon using this twin-roll method, a heat crown (difference in thermal expansion in the width direction of the roll) occurs as the roll surface temperature increases, so the ribbon shell as shown in Figures 6b and 6d. A roll gap difference occurs in the sheet width direction, and an unsolidified shell is formed at both edges and in the center of the ribbon.
As a result, not only the plate thickness becomes non-uniform, but in some cases unsolidified shells are generated, resulting in breakout, and the disadvantage is that a ribbon with a uniform plate thickness and good shape cannot be obtained.

As shown in Figure 3b, as the casting time increases, a heat crown occurs due to the difference in thermal expansion between the center and edge parts of the roll, and the center part becomes thinner than the edges, and the thickness deviation increases. Ta. Along with this, breakouts also occurred at the roll edges, and the board width became extremely narrow. On the other hand, as shown in FIG. 3a, when the quenched ribbon manufacturing apparatus of the present invention is used, the unsolidified shell is crushed under hydraulic pressure to prevent breakout at the roll edge, and as a result, It has become possible to continuously produce ribbons with small thickness deviations and good shapes.
