A conventional example of a billet heater will be explained based on FIG. In this figure, a chain conveyor 5 and a pinch roller 6 are installed inside a cylindrical heating coil 2 provided in a box-shaped case 1 and a cylindrical heating coil 4 provided in a heat-retaining case 3 adjacent to the case 1.
A large number of metal billets 7 are continuously fed in,
The billet 7 heated and heated by the induction heating action of the coil 2 passes through the inside of the coil 4 and is carried out from the billet outlet 3a of the case 3. The tip of the heated billet 7 of the heat-retaining heating coil 4 is connected to the outlet 3a.
This is to prevent the overall temperature from becoming uneven due to cooling by outside air. The outlet 3a is inclined forward and downward so that the billet 7 slides down under its own weight, and as shown by the chain line in FIGS. 2 and 3, the rear end of the billet 7, which is inclined forward and downward, is located at the inner periphery of the outlet 3a. Together with the coil 4, the cross-sectional shape is a vertically elongated oval so that the coil 4 does not come into contact with the coil 4.
このような構造ではコイル４の巻き枠が特別な
ものとなり、巻線作業も困難になるという欠点が
あつた。 This structure has the disadvantage that the winding frame of the coil 4 is special, making the winding work difficult.

FIGS. 4 and 5 show an embodiment of this invention, and the same parts as in FIGS. 1 to 3 are designated by the same reference numerals. In these figures, the heat-retaining heating coil 44 is divided into a plurality of parts in the axial direction, and this cylindrical divided coil 44a is attached to the heat-retaining case 4.
They are arranged in a step-like manner along the downward slope 43b in front of the billet outlet 43a of No. 3. The divided coils 44a have a vertically elongated cross-sectional shape, and are electrically connected after being formed using the same winding frame. The upper inner circumferential surface of the outlet 43a is also formed in a step-like manner so that the rear end of the billet 7, which is inclined forwardly and downwardly, does not come into contact with it.
