In addition, in the case that the temperature of hot rolled plate in steel plate manufacturing equipment is 1000 DEG C, make thermoelectric power generation unit with The distance of hot rolled plate is 280mm, and in the case where the temperature of hot rolled plate is 950 DEG C, if making above-mentioned distance be moved to 90mm And be controlled, then it can enter line efficiency highest thermoelectric power generation.
In the present invention, as shown in figure 12, thermoelectric power generation unit can be arranged at and the thermal source in addition to tubing etc. Distance corresponding to the output of temperature and/or thermoelectric power generation unit.This is done because：By being formed as above-mentioned setting side Formula, compared with being only flatly to set the situation of thermoelectric power generation unit, the displacement, secondary of thermoelectric power generation unit can be reduced Number, so as to reduce cost of electricity-generating.
For example, for Figure 12 middle body, in the case where thermal source is slab, thick bar, make the distance with unit Be formed as 720mm, and the distance of width end is moved to 640mm and is controlled, in addition, in the feelings that thermal source is hot rolled strip Under condition, if making to be formed as 280mm with the distance of unit, and the distance of width end is moved to 200mm and is controlled, then can Enough carry out efficient thermoelectric power generation.
In addition, in the present invention, as shown in figure 13, can be by thermoelectric power generation unit in the case where thermal source is tubing etc. It is arranged at distance corresponding with the output of the temperature of tubing etc. and/or thermoelectric power generation unit.This is done because：Pass through shape As above-mentioned set-up mode, compared with being only flatly to set the situation of thermoelectric power generation unit, thermoelectric power generation list can be reduced The displacement of member, number, so as to reduce cost of electricity-generating.
For example, in Figure 13 middle body, tubing is being replaced into the steel plate transport road of steel plate, make unit and steel plate away from From for 90mm, if distance controlling is 60mm by width end, efficient thermoelectric power generation can be carried out.On the other hand, in tubing Transport road, it is 120mm to make the distance of unit and tubing, if distance controlling is by end (being referred to as the temperature in tubing reduces scope) 60mm, then it can carry out efficient thermoelectric power generation.
The temperature of the width (the rectangular direction with the direct of travel of slab etc.) of slab etc. is from slab etc., steel plate End measure, and the position (in the present invention, referred to as width end) of two times or so of the length in thickness of slab~thickness of slab is anxious The low situation that falls sharply is more, therefore preferably makes the advance movement of thermoelectric power generation unit and be controlled.This is done because：Above-mentioned Width end, the possibility of the less result of obtained electric power is larger for the electric power for moving thermoelectric power generation unit.
For the embodiment set according to above-mentioned output of thermoelectric power generation unit etc., due to can be by thermoelectricity Generator unit is arranged to the shape of oval half, so compared with the situation without thermoelectric power generation unit, due to the dynamic of hot-fluid Change, so there is the advantages of heat insulation effect is outstanding, as a result, the thermoelectricity hair that the organic efficiency that can be formed as heat energy is excellent Electric installation.
