Problems solved by technology

[0021] The technology described in Patent Document 5 does not take into account the above practical considerations, and the power storage mechanism described in this document is not necessarily necessary
[0022] In addition, in the conventional thermoelectric power generation method, in an unsteady state where the front end or rear end of the steel material becomes a heat source, in order to prevent damage to the device caused by the height variation of the steel plate, etc., only the thermoelectric power generation method can be used. The device is set in the distance of the steel
Moreover, if it is installed far away from the steel material, the thermal energy of the high-temperature object cannot be well transferred to the thermoelectric power generation device, so there is a problem that it cannot be efficiently converted into electrical energy

Embodiment 1

[0253] In order to confirm the effect of the thermoelectric power generation device of the present invention, the following test was carried out, that is, in figure 2 The configuration shown is used with a 1m 2 The thermoelectric generation unit with an area of ​​, and the thermoelectric generation unit is set at Image 6 In the position of C, confirm the output of each thermoelectric generation unit.

[0254] As Invention Example 1, a test was carried out in which the distance between the thermoelectric generator and the thick bar was set at 3000 mm when the thick bar was passed through the plate, and after the front end of the thick bar passed, the thermoelectric generator was moved, and the thick bar was separated from the thermoelectric generator. The distance control is 720mm. In addition, the temperature of the thick bar is approximately 1200°C in the center of the width direction, and the width end (represents a range within approximately 80 mm from the width end fac...

Embodiment 2

[0273] In order to confirm the effect of the thermoelectric power generation device of the present invention, the following test was carried out, that is, in figure 2 The configuration shown is used with a 1m 2 The thermoelectric generation unit with an area of ​​, and the thermoelectric generation unit is set at Figure 7 In the position of F, confirm the output of each thermoelectric generation unit.

[0274] As Invention Example 8, a test was carried out in which the distance between the thermoelectric generator and the hot slab was set at 3000 mm when the feeding of the hot slab was started, and after the front end of the hot slab passed, the thermoelectric generator was moved, and the The distance from the hot slab is controlled to be 720mm. In addition, the temperature of the hot slab is approximately 1000°C in the center of the width direction, and the width end portion (represents a range within approximately 80 mm from the width end surface of the hot slab in the w...

Embodiment 3

[0293] In order to confirm the effect of the thermoelectric power generation device of the present invention, the following test was carried out, that is, in figure 2 The configuration shown is used with a 1m 2 The thermoelectric generation unit with an area of ​​, and the thermoelectric generation unit is set at Figure 8 In the position of G, confirm the output of each thermoelectric generation unit.

[0294] As Invention Example 15, a test was carried out in which the distance between the thermoelectric generator and the slab was set at 3000 mm when the slab was passed through, and after the front end of the slab passed, the thermoelectric generator was moved to place the distance between the slab and the slab. The distance control of blank is 720mm. In addition, the slab temperature is used (in the present embodiment, when simply referred to as the slab temperature, it means the temperature of the central part of the slab.) is about 1200° C. The range of the end surfac...
