Three types of flux as shown in Table 1 were prepared with a blending ratio of O: 10 (or more by weight). A composite wire with a predetermined length (200 m) was produced by putting a predetermined weight of flux into a hopper using the steel strip. At this time, the inclination angle of the wire at the flux injection part was changed, and the amount of flux remaining after manufacture (the amount of flux that was not introduced into the wire) was measured. The results are shown in Table 2.

At an inclination angle smaller than the collapse angle,
It is clear that the prescribed amount of filling cannot be achieved. Note that fluxing in the above refers to the ratio (unit: %) of the flux weight to the weight of the steel strip.
