つた。 As a conventional heating furnace of this kind, there are, for example, those shown in FIGS. 1 and 2, particularly those having a structure that can handle short materials. That is, in the same figure, a is a walking beam, b is a fixed beam, c is a finger of the extractor, d is a hearth, e is a furnace side wall, f is an extraction wall, g and
g' is a steel material, h, i, and j are steel material mounting tables provided in the preheating zone, and k is a burner. To explain further,
Since the upper surfaces of the mounting tables h, i, and j are uniformly flat, as shown in FIG. 2, scale m is deposited on the upper surfaces of the mounting tables h, i, and j during operation. Therefore, the stability of steel materials g and g′ is lost, and
There were disadvantages in that the upper surfaces of the refractory material mounting tables h, i, and j were eroded, and the back surfaces of the steel materials g and g' were damaged. In particular, short length materials such as steel material g' have the disadvantage that they are extremely unstable due to the above-mentioned scale, and may tend to tilt or fall.

を示したものである。 In Figures 3 and 4, 1 is a walking beam, 2 is a fixed beam, 3 is an extractor finger, 4 is a hearth, 5 is a furnace wall, 6 and 6' are steel materials (slabs), and 7 and 7' is a steel mounting table made of fireproof material.
The upper surfaces of these mounting tables 7 and 7' have horizontal surfaces 8 and 8' provided in the width direction of the mounting tables, respectively.
consisting of inclined surfaces 9, 9';
9' are provided such that the direction of inclination is alternately changed in the longitudinal direction of the mounting table. Reference numeral 10 denotes a steel mounting table made of fireproof material, which is located between the above-mentioned mounting tables 7 and 7'.
Similarly, the upper surface of this mounting table 10 consists of a horizontal surface 11 provided in the width direction of the mounting table and an inclined surface 12, and the inclined surfaces 12 are provided with the direction of inclination alternately changed in the longitudinal direction of the mounting table. ing. Further, each of the horizontal surfaces 8, 8', 11 has a small width to support the load of the steel material, and each of the inclined surfaces 9, 9', 12
is tilted downward to the extent that the scale falls. In addition, 13 shown in Figure 3 is the extraction wall,
14, 14', and 14'' shown in FIG. 4 indicate scales.

の幅が小さいから、その堆積は殆んどない。 In the scale removing device for the steel material mounting table of the heating furnace configured as shown in FIGS. 3 and 4, even if scale is to accumulate on the upper surface of the steel material mounting table 7, 7', 10, the Since the inclined surfaces 9, 9', 12 are provided, as shown in FIG. 4, along the inclined surfaces 9, 9', 12,
14, 14', 14''. Therefore, scale will not be deposited on the inclined surfaces 9, 9', 12. That is, the load of the steel material 6 will fall on the horizontal surfaces 8, 8', 11. The load of the steel material 6' is supported horizontally on the horizontal surface 11, and the scale is
Since the inclined surfaces 9, 9', and 12 are provided with the direction of inclination alternately changed in the longitudinal direction of the steel material mounting table, it is possible to prevent the steel material from accumulating in the center of the steel material mounting table 7, 7', and 10. ing. Therefore, if scale is to be deposited on the upper surface of the steel material mounting tables 7, 7', 10, only a limited horizontal surface 8,
8', 11, but these horizontal planes 8, 8', 10
Since the width is small, there is almost no accumulation.

好となる。 As mentioned above, the top surface of the steel material mounting table of the present invention is
It consists of a horizontal surface with a small width that supports the load of the steel material, and an inclined surface that slopes downward from the horizontal surface to the extent that the scale falls, so there is almost no accumulation of scale on the top surface of the steel material mounting table. Therefore, the steel material is stabilized, the back surface of the steel material is not scratched, and the top surface of the steel material mounting table is not eroded. Moreover, the portion of the top surface of the mounting table that does not come into contact with the steel material is smaller than before. As the temperature increases, the heat transfer from the sloped portion to the steel material increases, and the temperature distribution of the steel material becomes better.

きい。 In addition, since the inclined surfaces are oriented downward by alternating the direction of inclination in the longitudinal direction of the mounting table, falling scales do not accumulate in the center of the steel material mounting table, and the horizontal surface is oriented downward in the longitudinal direction. Therefore, the load of the steel material is stably applied to the mounting table, and there is only a slight accumulation of scale on the horizontal surfaces at both ends in the width direction. The effects of the present invention are extremely large, such as being able to support steel materials in an extremely stable manner, stabilizing the load acting on the mounting table, and guaranteeing an extension of the life of the mounting table.
